The first thing I should say is that I have not yet seen the new Star Trek movie, though I do intend to. (Is it any good?) But I have seen a raft of articles about the science of Star Trek (what should the collective noun for Star Trek stories be? An “enterprise” of Star Trek stories?) over the past week.

All this reminded me that I have the distinction of actually having attended a conference a couple of years ago dedicated to building a warp drive, organised by the British Interplanetary Society, in London. The society’s motto is “From imagination to reality...” and that was very much the spirit of the meeting as engineers and physicists met to seriously discuss if, when, and how warp drives could be manufactured, allowing faster-than-light travel. (One participant did wear a Klingon tie, but he did so with irony.)

Jeremy Gardiner kicked off by boldly predicting something that no man had predicted before: that we will be whizzing around in FTL spacecrafts by 2180. His estimates weren’t based on evaluations of the physics or on engineering considerations, but—interestingly—he looked at the timescale for other seemingly wild ideas to shift from science fiction to science fact. In particular, he compared the case with the historical development of the technology needed to travel to the moon, identifying six steps society needs to pass through from “conjecture” (1657 in the moon case, when Cyrano de Bergerac wrote about journeying to the moon), passing through the phases of “speculation,” “science,” “technology,” “application,” to final “realisation” (1969 for the moon case, with the Apollo landings).

According to Gardiner, we are now in the “speculation” stage of building a warp drive, following a mathematical proposal in 1994 by Miguel Alcubierre for making a “warp bubble” around a spacecraft, contracting space ahead of it and expanding it behind the craft. The craft surfs along in its bubble, without ever technically breaking light’s speed limit, but reaching its destination faster than a light beam forced to travel around the bubble.

That all sounded great, but I wanted to know if anyone actually had any ideas for how to practically implement this. One speaker, Richard Obousy, promised that he had the answer. His method was based on the string theory notion that there are extra spatial dimensions. All you need to build a warp drive, said Obousy, is to manipulate the size of the cosmological constant in front of and behind the craft, by contracting and expanding the curled up extra dimensions respectively, to build your warp bubble. Ok, I said, but how would you actually set about contracting and expanding the curled up extra dimensions—given that we don’t even know they exist? He wasn’t sure, he replied, as it’s still a work in progress...

At that point I lost interest in his warp drive. However, since then Obousy has published his work on the warp drive, so you can check it out, along with a video of one of his talks, on youtube.

I didn’t follow up the warp drive meeting, or think much more about it until the recent hype around the new Star Trek film. But thinking back, one talk, by Claudio Maccone of the International Academy of Astronautics, did make me stop and think. He didn’t make any bold claims, and he didn’t have any speculative blueprints. But he did make a plea to physicists on behalf of engineers: sort out your math. The problem with attempting to build any kind of warp drive, he said, was that engineers and computer scientists are baffled by mathematical conventions that physicists use, for instance, their use of natural units, in which certain physical constants (the speed of light, Planck’s constant...) are set equal to 1. At the moment, he said, progress was being hampered because scientists in different disciplines simply don’t understand each other’s conventions. Put another way, if you want a warp drive, Spock and Scotty need to speak the same language.

Quantum theory makes the warp drive unlikely. The Alcubierre warp drive requires negative energy. Quantum mechanically this means there are no lower bounded states. This is a disaster, for it means mass-energy can fall into an endless well and produce a huge amount of energy. it is related to Dyson's observation that letting electric charge e ---> ie i = sqrt{-1} results in radiation from the vacuum.

Only a decent theory of quantum gravity will tell us for sure, but my bet is that macroscopic wormholes and warp drives are not possible.

Lawrence,

If you can change the speed of light by understanding how the speed of light is enforced, new things become possible. Of course, even if you could, getting a mass to achieve 100c (100 times speed of light) appears to require insanely high energies: K= 1/2mv2 = 1/2 m(100c)2 = 5000mc2. Warp drive accidents would result in very dramatic explosive events.

But there is another way...

Hi all,

Personnally if it exists a super velocity ,it will be for the rotation of the quantum spheres around themselves ,those velocities are proportional with mass .

In our physical Universe and its laws the light velocity which is linear is maximum I think .But for quantum spheres around themselves it's an other story .I see these spheres and the velocities of rotations like foundamental ,all is in a logic of rotation .The frequences ,the polarities,the senses , the volumes of spheres ,the fields ,...in fact those velocities are like codes of comportment.It d be interesting to know the quantum architecture of spheres for water for exemple and the liquid comportment on Earth with its parameters .Why H2O is H2O ,what is the spheres architecture and their velocities of rotation at 30 degrees celsius for exemple and what is the velocities of rot for 100 degrees celsius and 0 .

If we take the cosmological numbers of spheres and their volumes ,more an universal law about mv like a constant quant/cosmol ,thus it's possible to know the specific architecture of water like gauge ,or H ,it's there the chemestry is important and the stability of molecules .

About energy ,the maximum is everywhere in maximum quantity after different steps in the quantum architecture towards the wall .At this limit all has the same maximum .

It's interesting this link if we consider the quantum Universe and the cosmological universe ,In this logic ,time is a part of the increase of mass and energy in the physical Universe in evolution .Thus it's always a question of limits towards walls in the quantum dynamic and the cosmological evolution .

The maximum energy is in all things with its limits of perception .

It's a very important foundamental because the applications are incredible .

It's the message of E =mc² all has the maximum quantity of energy .

In my model I perceive the light like a chief orchestra ,the light begins of the center of our Universe ,towards centers towards ultim cosmological membran sphere ,the curvature by gravity implies a spherization of all ,of the light .

The Light is like an ultim frequence of evolution.Thus like a constant of evolution like the time ,both of them are constants of evolution .They won't change I think .The space on the other side changes its volume in time,expansion and accretion.



In this logic of centers ,the comportments of our Universal center are so far of us but so intriguing ,it's there the ultim code .All is linked with this universal center where all begins ,began .

I don't imagine too whormholes and warp drives like possible .

Sincerely

Steve

The speed of light is an absolute invariant. The "real McCoy" author kept saying dx^4 = icdt, which is a trivial statement but is worth considering. Everything is moving the speed of light locally, and it is really just a way of comparing a meter stick measure of one dimension in space with the fourth dimension of time.

General relativity is a bit odd, for locally in a flat Lorentx frame the speed of light is an invariant. Yet glocally points of space can be dragged or moved by almost anyway imaginable. In cosmology points on the spatial surface of the universe can slide apart with v = Hd, H = hubble constant and d = distance. The CMB limit is about 75 billion light years away, and this means the points of space frome where we observe these photons from are sliding away at about six times the speed of light! This is also how black holes can form. In these cases we are comparing physics between two frames which are not mutually the same or the same Lorentz frame. It is also interesting that photons from the CMB limit can reach us!!! Very strange indeed, but it does work out.

The warp drive does some sliding of spatial points. It compresses the distance between points in a small region in front of a flat region (inside the warp bubble) and expands spatial distances behind the flat region in the bubble. So in a funny way this does amount to adjusting the speed of light by playing with the curvature of spacetime. Yet, this leads to some pathologies, primarily it violates the Hawking Penrose energy condition, particularly the weak condition T^{00} >= 0. If this momentum-energy T^{00} is determined by quantum fields T^{00} < 0 leads to some very troubling problems with quantum theory.

Lawrence,

Lawrence,

The mathematical physics is completely correct as far as can see. But it’s not being interpreted correctly. I offer a succinct interpretation that can explain QM, GR, space, mass, time and String Theory. Just give me a few sentences to appeal to your interest.

The Laws of physics in free space have to be implemented somehow; to say they are Platonic absolutes is to suggest a mysterious cause. All of the mathematical physics is correct, but only part of it represents the a priori phenomena; the question is, which part? Consider two “Action at-a-distance” phenomena, Newtonian gravity and Coulomb’s law; what does it take to implement this kind of phenomena? In special relativity, two inertial frames with some relative velocity experience absolute speed of light, but peculiar temporal affects? What is the connection between them that is capable of transmitting information between the two frames? And finally, wave mechanics and Schrödinger’s equation is more than suggestive of wavy objects.

The real a priori objects that show up everywhere in the mathematics, are one dimensional string-like objects. An over simplification would be that every particle in the universe is connected to every other particle by a string. The string can transmit information and energy at the speed of light, c = v = sqrt (Tension/density). Strings are straight and are under tension; they can vibrate. More accurately, particles are “string” hubs with a finite, more reasonable number of connections. Rest mass is dependent upon the number of strings attached to the particle; a proton would have about (1/6E-27/9E-31) 1800x the number of strings passing through it than an electron would have. Photons would be vibrations/disturbances that propagate along the string and spread out across many strings. The mechanism that explains probabilistic detection remains unknown. The strings have peculiar properties. They are probability amplitudes. They pass through each other (so as to avoid knotting). They implement action at-a-distance forces. There lengths can and will change as particles move around.

Advantages to this interpretation:

1. Twin slit experiments can be explained as the photon energy (from even a single photon) causing the already present string paths to vibrate.

2. Elaborate and hard to imagine mental constructs can simplify into sophisticated 3D networks whose links transmit disturbances at the speed of light.

3. Fields, which are described with waves anyway, become collections of strings.

4. …

As for warp drives and changing the speed of light, one would have to change the properties of the strings (something I don't know how to do, yet).

Jason Wolfe/wulphstein@gmail.com wrote on May. 20, 2009 @ 07:28 GMT
Strings are allowed to rotate along their axis (like logs rotating in the river).

If mass is the consequence of the number of strings attached to a particle, then black holes can be desrbided as the maximum number of strings for a given volume; all of these strings are under tension with everything else in the universe. This idea relates quantity of strings to mass and gravitational attraction. There really is a weave of space-time.

Please challenge me if you don't like my idea. I would like to figure out where the interpretation doesn't work.

Hi Spheric Steve,

Section 3.2 of my E12 TOE predicts charged scalar fermions, ie. TACHYONS!

Theoretically, these charged tachyons radiate electromagnetic energy until they asymptotically approach zero energy = infinite velocity (if our equations for Special Relativity can be applied to imaginary masses). Numbers like zero and infinity make me nervous - there is probably a quantum and/ or Dirac Large Number limit. These tachyons are created and annihilated in pairs.

Could we control tachyons inside a gravitational bottle? It would be the gravitational equivalent of using a magnetic bottle (such as a tokamak) to confine plasma. If we could contain tachyons thus, we may be able to release them such that we can steer our spaceship. Could we envelope our spaceship with a tachyonic field and trick Gravity into thinking that the entire spaceship is a tachyon? And could we steer such a spaceship?

To Jason’s point, we still do not understand the full consequences of Strings and Quantum Entanglement…

By the way, your rotating fundamental spheres are angular momentum, not linear momentum. I do not think they say anything about the speed of light. I suspect the Universal Foundation has a String/ Sphere dual nature.

Hi Dr Cosmic Ray ,

Happy to read you again .

A duality between spheres and strings ,it's interesting indeed ,if I imagine a closed circle membran and a sphere membran ,it's relevent about the frequences ,vibrations and harmonization in Time Space evolution.

What is interesting too is the different step before ,the different volume too ,inside the sphere too .

The quantum architecture in this logic is correlated with cosmological spheres and its volumes ,ratios and proportions .

Just for fun ,let's imagine a sphere with a kind of ultim liquid inside and a membran betwenn math/phys world ,and a code of becoming if I can say .

with those rotations of spheres ,many forms of complementarity are possible .

The rotation and this kind of incompressible liquid imply a specific comportment .

But In a global point of vue ,I see the foundamental in the sphere ,with a big big majority ,a string is divisible ,a sphere no ,it's the perfect balance between strenghts and that everywhere in our physical universe .

Dear Ray ,

could you tell me more about a tachyon ,I have difficulties to imagine it .

Is this supravelocity is linear in this hypothesis ?

thus I understand the time travel hypothesis and the check of futur and past,but really impossible for me to have possibilities to travel in Time .

I think it's more interesting to focus on Space and the check of energy ,it s logic in an evolution point of vue with this time constant .

You say (hihihi me too) Numbers like zero and infinity make me nervous ,

personnally I think zero is a human invention ,the infinity is behind our walls .Thus two human inventions and that to imagine the limits of perceptibility .

I use zero but I don't imagine it ,I use infinity but I don't imagine it hihihi

The zero don't exist .like a mirror of the reality ,we can break this mirror ,hihi ...

The inclusion of string theory and anything else does not change the problem of the speed of light. The warpdrive exists mathematically by violating the Hawking-Penrose energy condition T^{00} < 0. This causes all sorts of trouble for quantum mechanics. If this condition T^{00} < 0 holds it also means that wormholes and even time machines can exist. We are all familiar with the paradoxes of time travel.

I don't think that the universe is self-contradicting. To avoid causality paradoxes with time travel is a tricky thing to do. Quantum gravity under these conditions would be extremely difficult to formulate. It is hard enough as it is! I suppose in physics we can't ever say something is absolutely impossible, but I do think we can say certain things are very improbable or implausible. Warp drives, wormholes, Krasnykov tubes, time travel and so forth are I think unlikely.

Dear Spheric Steve,

Consider the equation (pc)^2=E^2-(mc^2)^2 with imaginary mass (a tachyon), such that -m^2>0. Kinematics demand that a low-energy tachyon travels infinitely fast, while a very energetic tachyon "slows" down and asymptotically approaches the speed of light, so that its speed is always more than c. Electrically charged tachyons must radiate electromagnetic radiation, which reduces their energy and increases their velocity. (Yes, it sounds backwards, but tachyons are like that).

You know how I feel about the number "infinity"... I was an undergraduate student at Florida State University when Paul Dirac was a Professor Emeritus there. I will continue to carry on Dirac's Large Number Hypothesis...

Can we use these exotic particles to propel a spaceship? I'm not sure. Could Planck or Einstein have predicted the impact of Quantum Mechanics on our modern lifestyles and economy over 100 years ago? I'm not sure.

One of my friends at NASA was playing around with the idea of stepping through a multi-dimensional (pick a number 10, 11, or 12 dimensions?) doorway into another time and/ or place in the Universe. The idea is that there may be a higher-dimensional short-cut versus the standard four dimensions. I have doubts about that approach because hyperspace is more likely to be small and require high access energies; rather than inflated, invisible, and require low access energies.

Have Fun!

Hi Dr Cosmic Ray ,

Dirac Was an incredible mathematician and a searcher of truth ,the secret is there I think .

His Hypothesis is relevant about our limits .

In my quantum model and the cosmological link ,the numbers of stars ,planets ,moons ,....are so important ,I don't see an other universality for the quantum architecture and its rotations of spheres .

This quantum architecture is like a code of becoming in space time evolution .

You say "Can we use these exotic particles to propel a spaceship? I'm not sure. Could Planck or Einstein have predicted the impact of Quantum Mechanics on our modern lifestyles and economy over 100 years ago? I'm not sure."

So many secrets there in this local mechanic .The increase of energy towards walls ....all has the maximum quantity of energy but before the check of fields....it's the same with our global energy system by nuclear ,where are we ,still far of the wall .Furthermore our global economic system decrease the velocity of evolution and thus the technology,always this individualism against the complementarity .

The quantum mechanics has many secrets to discover ,personnally I think That it's possible to check the space but not the time ,a, interesting point of vue is the decrease of space in an contraction evolution ,thus the space between mass decrease thus intresting for the check of space .

If we consider this ultim sphere ,this ultim harmony between mass ,it's so fascinating for the interactions .The human species is a explorer ,a catalyzer ,a discover,....we must check the velocity ,the mobility ,the communication.

Sometimes I extrapolate the lifes in our Universe ,the astrobiology is fascinating ,how are those intelligences ,how are their evolutions ,hope they don't make the same silly things than us on Earth.In all case ,one day we shall communicate with us and more ,always the complementarity between all like in our quantum architecture and its codes .all lives ,all evolves ,all towards harmony .The light in this logic is the ultim frequence ,and the universal center where all begins .

It's a pleasure Ray to discuss with you .

and again I find theory with its head in the clouds, but that's what makes dreaming fun. now warping space on that scale isn't as easy as it sounds. it would require a large amount of mass (or E equivalent) perpetually warping the space as well as moving on the up slide of the warped space (think of E principles for this) the worst part is the distortive affect it would have on the craft itself. and thats just for movement. For tricking FTL travel without moving FTL u would have to warp time a huge amount (probably doing both at the same time lol) which is even more fun. warp travel Possible YES probable no . imagine riding a grave wave on the edge of an event horizon without getting pulled in or left behind because it to would have to move. then u have to stop it would be really hard surfin.

Jason Wolfe/wulphstein@gmail.com wrote on Jul. 1, 2009 @ 18:41 GMT
This warp drive conundrum is becoming an obsession. Since physics, as physicists understand it, is not very conducive to FTL travel, we have to think about how the universe is constructed/assembled.

From a QM point of view, I believe that prior to the Big Bang, there was nothingness; this is equivalent to V(r) = infinity. In other words, the non-existent nothingness in which the universe expands, does not allow particles, light or anything to exist in it's n-dimensional space. When the Big Bang occured, the universe (space-time expanded). Space-time is, for lack of better language, made of something (strings perhaps). It is the expansion of this something that reworks the potential energy topography to something less then infinity. As the universe expands and cools, the background energy approaches the zero point energy. I believe that the substance of which space-time is made, creates the background potential energy topography for n-dimensions. Time is nothing more than the fact that energy flows across the available states similar to the way that water seeks its own level.

With the tesselation/crystal approach, you don't get the expansion of space because crystals don't really move. I really like the idea of a molten polymer because superstrings are similar to long carbon chains.

I like the idea that superstrings can have a large number of states such that the low energy states are conducive to three spatial dimensions and allow for rotation as well. In the same way that a plastic cup holds water, is it possible to say that a superstring/polymer-like universe can hold energy in ways that behaves like Hilbert space?

So why are planck's constant, speed of light, etc absolutes? I don't know yet. But I'm trying to get at two energy topographies, one for the standard model and one for hyperspace. I'm willing to bet that trying to get around in hyperspace, using tachyon fields, will get you lost very easily unless you use a lot of energy to direct your spaceship to exactly where you want to go. I'm suggesting that a hyperspace has Quantum behavior in the sense that a detection of a particle in regular space is a parallel to an accurate hyperspace jump. Unless you put a lot of energy into the jump, you will not complete your jump anywhere close to your intended destination (in spite of the fact that you jumped 1 million lightyears away).

Hi Jason ,

It's indeed interesting .Those anomalies are relevants ,

If I take a simple constant m v x =m'v'x'...it's interesting about the variables of velocities of rotations who imply thus different mass thus gravity .

It's logic in this optic to have this kind of problems .

The architecture of gravity and fields in a spherical logic is necessery with some adapted new parameters and variables .With this kind of sphere with spheical fields inside and those parameters,we could adapt and change parameters .If some weak changements of the velocity of rotation of a body are evident thus the mass and gravity too have these changements and that proportionaly.

I think that all is correlated with these rotations of spheres and that in the quantum and cosmological dimensions .

The gauge is possible with thoses rotations and that to have the best architecture .

I have a unknew (with unknews)in this equation mvx like a constant .m the mass of the sphere ,v the velocity of rotations of the sphere ,and x a variable due to the nature of the sphere (liquid ,solid ,gaz,proportion,density,not compressibility ,volume,pression,......more the complexification and the spherization thus the increasing of mass and the decreasing of space ).

I have some questions about the sphercal laws .

Some parameters can indeed change with the centers (planets,stars,galaxies....)thus we can extrapolate with galactic center and its laws ,stars and its laws ......

To elaborate correctly this universal constant ,I need datas and helps of course but the whole is there .

This new constant will permit to link all I think .The rotations of spheres like a driving force of the harmonization towards ultim sphere.

In the quest to come up with the hyperdrive (or something plausible), I've been looking very closely at mesons/baryons/hadrons (strong force mediators and quark stuff). There are six kinds of quarks + their antiquarks for a total of 12. I had the following idea. What if there is yet another symmetry for sub light speed/FTL. This will again double the number of quarks. I'm talking about tachyon quarks. When I tried to figure out what their properties would be, I thought of gravitons and Higg particles. If I imagined that gravitons and Higg particles are really tachyon quarks, would I be violating any physics principles?

I'm trying to come up with some UFO physics, something to explain hyperdrives and the bending of space-time (Alcubierre drive). The idea I have is to take a semiconductor material, or a metal, and replace some of the proton/neutrons with tachyon quarks. I thought it might be a possible way to couple electromagnetic forces with gravity-like forces and space curvature in a logical way.

Is there any reason to discount the idea that gravitons and higgs particles are tachyon quarks?

It's not quite a hyperdrive; but a wormhole with moveable gates would work just as well.

You fly your space shuttle (sub light speed) into the entrance way. Upon crossing the threshold of the wormhome, your shuttle is coated by a protected boundary that isolates the craft and crew (in standard space-time) from the hyperspace wormhole. Once inside, the wormhole treats the globular object (the coated shuttle) as a "mass" in a pendulum. When the wormhole/hyperspace globular object is released and allowed to move, it accellerates up to multiples of c. At the halfway point, it reaches its maximum velocity with zero accelleration, then it starts slowing down. The shuttle, relative to the protective boundary which the wormhole sees as a globular "mass", the shuttle is at rest and not accellerating. Towards the other end of the wormhole, the shuttle is slowing down to a stop. The shuttle passes through the exit where the protective boundary is removed. The gates on either end can be moved without changing the 'altered' laws of physics of the worm hole.

Yes, I know that the physics community doesn't have the slightest clue how to do any of this. Yes, I know about the tv show StarGate. Yes, I know that any real physicist would repeat the chant "that's impossible, that's science fiction". On a positive note, I don't have to worry about steering or propulsion.

Jason,

Back in the 90's, one of my NASA colleagues (now a Prof Emeritus at UAH) was trying to combine the Star Gate concept with String Theory. His basic idea is that we might be able to find a multidimensional shortcut between doorways. Your basic idea is that we might be able to find a (wormhole/ multidimensional?) super highway with a speed limit greater than c between doorways. The net effect seems similar, but the Physics is different. I wonder if an observer could determine that the Physics was different?

In the Nineteenth Century, travelling to the Moon was also science fiction...

Let's go for fun and science fiction ,

A door like in Stargate ,and a wormhole ,thus the rotations implies gravity thus possibility to coordonate the frequances of a wormhole and create a symetric space thus a possible teleportation with a good architecture .

Don't forget too to calculate the quantum spheres and the nature of the polarization ,here a human ,Quantum spheres .......HCNO ....cells ...human

Thus the check of rotations is important to harmonize the frequences .

Thus the spherical fields must be very well calculate and the reproduction must be well teleported .I don't want be like in the film the fly.Thus the quantum coded spheres and their rotations must be well replicated .because all is linked by rotations and spherical fields .To reproduce an human ,it's difficult No .We are not God in fact .

Not teleportation. Pendulum Wormhole! In Las Vegas at one of the Casinoes, they have a ride called the Sky Screamer. They strap you down and lift you up in this pendulum system. They live you up about 150 feel, and then they release you. You swing back and forth about 8 or 9 times. Ok, I did scream like a little girl, but it was so much fun. It's a little bit like that.

Nobody knows how to really manipulate space-time without using black holes and singularities. I look at the various electromagnetic field equations and I see charges with velocities crossing field (perpendicular) to create forces (perpendicular to the plane); these cross products give me ideas. Yes, you guessed it; I'm looking for hyper dimensional forces that can shape space-time. I'll let you all know if I come up with anything interesting.

Hi Steve,

I'm still working on how to actually build a Pendulum Wormhole. Within the cylindrical region of the wormhole, I'm ok with allowing the physics constants to vary, symmetrically, along the pathway. The shuttle must be enclosed within a boundary to protect it from the extreme laws of physics inside of the wormhole. I do not want to use black holes and other huge mass-energies if it can be avoided.

I was thinking about how E&M has coupling between electricity and magnetism; in comparison, mass/gravity has no such coupling, that is obvious. I want to assume that electromagnetism/photons are a separate phenomena from mass/gravity. If electromagnetism is implemented by virtual photons, then mass/gravity would be implemented by virtual Higgs particles and virtual gravitons. But I'm not entirely convinced that they really are point like particles at all. In fact, gravity doesn't seem like a point-like interaction at all.

As for creating wormholes, there is going to have to be a hyperdimensional force involved of some kind. In electromagnetism, the Pointing vector S=E X B (times some constants). I'm looking for a hyper-force that has manifestations in the space-time + hyperspace in a similar kind of cross product way.

I'm going under the assumption that a solid-state crystal picture in not correct. The balloon/giant photon/5D wave-front idea is more compatible with the Big Bang and warping of space-time. Furthermore, I am assuming that QM is absolute and GR is a construct of QM. In other words, I think entire universes can be created and manipulated, but the multiverse is stuck with QM, like it or not.

As for the Quaternion model of a scalar energy dimension + 3 spatial dimensions, if you imagine a boiling pot of water, I believe that virtual photons behave similarly to the bubbles. I believe the the virtual photons (virtual Higgs/gravitons) are manifesting space and an energy dimension by their intereactions. Time/causality only occur if the virtual photons (Higgs/gravitons) are allowed to transmit their momentum/frequency information; kx - wt.

If a pendulum wormhole were to be created, virtual photons would not be of any use; so don't expect lightning or radio contact from the wormhole. It might have to be a region of gravitons/Higgs particles only. The two dimensional surface/boundaries that isolate the wormhole entrance and shuttle are another physics I'll have to think about. If your worried about observers on the other side of the boundary (by observers I mean quantum particles and fields), I'm willing to restrict anything from crossing the boundary. In fact, if electromagnetism does not exist inside of the wormhole, then the boundaries will have to be opaque.

I'll keep thinking about it. If I notice any 6D+time bosonic gravitational forces anywhere, I'll let you know.

Hypothetically, if two shuttles entered from each side of the pendulum wormhole, each with the appropriate protective boundary, if the two shuttles pass through each other at velocities exceeding the speeding of light, then interaction or a collision cannot occur. A collision requires electrostatic interaction, which requires virtual photons. But photons can only interact at the speed of light. For two shuttles passing each other at faster than light speeds, an electrostatic interaction would not have time to occur. I'm assuming the shuttles have masses that are too small to be gravitationally relavent.

Hi Jason,

I understand better .

I d like ask you one thing about the bosons de Higgs ,what do you think about its mass ,its linear velocity and the velocity of rotations .

Let's admit this weak interactions and the Einstein Bose Stat .

This equation thus n=g(i)/exp{Ei-u/K(B)T-1}.

We see the Thermodynamical balance ,in the Bose Einstein condensate ,the weak temperature are in coherence too .

If I take my link with rotating spheres ,a big vel of rot of the sphere implies a small mass ,thus the light has the maximum in the two sens ,linear and around themselves,I d say what these bosons have a big velocity of rot and a proportional weak mass .

If we change the temperature ,like a condensate ,thus we change all velocities of rot of quantum spheres ,thus the thermodynamic and gravitational effects are invariants in their balances .

If the gauge is the light ,the graviton and the higgs bosons are how in this case and do you think there is symetric frequenes .And how keeping the frequences informations .

If one is attractive ,the other repulsive,what I find impossible is the time travel ,but a space travel is interesting .

Let's take a paper ,one page ,you take the plan between two points ,for exemple 25 cm ,and you approach the point of the plan .The two points are 0.1 cm .It's like we cut the Einstein Rosen Bridge and create a circular vortex between the two points ,the two gravitational singularities but not with time but with space .

What do you think Jason ?

The aim is to find its velocities in fact and thus ...

What I find relevant is the evolution point of vue and the diffusion of these waves since the beginning ,here the Big Bang Theory or a multiplication of el part ,the general relativity is on the road always .

Let's take now the spin 0,1,2 .and the results of the extrapolations ,thus the restr relativity must be adapted ,the rotations of the spheres and its ponctuality is totatly different than a linear velocity ,in this case the rest relativity is not applicable .

It's important to encircle the real universal dynamic of gravitational wave and the graviton ,the ultim rotating codes sphere or spheres .The Linear velocity ,the gauge ,the limits ,and the rotations which implies mass.

Hi Steve,

I've been thinking a lot about wormhole physics. After trying to explain these ideas to my girlfriend and her brother, I realized I need to make this as simple as possible.

Our physical universe can be considered like an expanding balloon. The Cosmological constant can be compared to the air pressure of the balloon that causes it to expand. 3d space can be compared to the 2D surface of a balloon. Quantum particles can be described with superstrings within a parallel pair of D-branes (effectively a conduction band). These d-branes are separated by a thickness d that can be compared to the thickness of a balloon; but this thickness 'd' is a placeholder for additional work.

The Higgs field, mass, speed of light, gravitational constant, and charge are all properties of the 3D surface of the expanding/contracting 4D balloon-like universe. Objects that can expand/contract subject to the Cosmological constant are called, by me, for now, Inflatons. Our physical universe is an Inflaton. Inflatons are quantum particles that, if stimulated with radiation (details not known), can expand. Programming the laws of physics for an Inflaton are left for later discussion. Once programmed, the inflaton has to be collapsed back to a singularity (quantum particle) to have it's physical laws reprogrammed. Part of the radiation will be used to add quantum particles (superstrings) to the inflaton. While generally hyperspherical in shape, they can be stretched into stable wormholes and anchored at both ends. More info to follow...

Steve,

While conservation of linear momentum is like a ball and chain to the hyperdrive, I dare not get rid of it. If I did, my whole line of conjecture would be lost in hyperspace.

For a shuttle to enter a pendulum wormhole, it must be able to preserve its own laws of physics, or face disintigration. The pendulum wormhole has its physics streamlined to allow maximum linear velocity in both directions. Since various subatomic particles are not stable in our universe, I expect particle stability to be an important technical challenge to overcome. There will exist particles/materials that are stable within the wormhole. Those particles/materials need to completely coat the shuttle; both to provide something that can accellerate in a wormhole, and to provide part of the protective barrier around the shuttle. Since, E=mc2 in our universe, I would hate to think how much energy it would take to supply enough material mass to completely cover the shuttle. If E = m(c')2 where c' (speed of light in the wormhole) = 100c, the material-energy cost will be enormous.

In a previous post, I suggested that electromagnetism and photons do not exist in the pendulum wormhole. Does this mean that mass cannot exist? I believe it takes something like a Higgs field to provide mass. But a Higgs field is described as the quantity of interactions that resist accelleration.

In the interest of purely fun speculation, is there any chance that a Higgs field manifests as momentum eigenstates that exist across all of space? Let's pretend that the 10 lightyear pendulum wormhole has momentum eigenstates in (1Kg)(1m/s) = 1Kgm/s increments. Let's pretend that each of these eigenstates spans the entire length of the wormhole. Whatever rotational eigenstates there could be, are blocked out, for now. For some wormhole material moving along the length of the wormhole, there is no reason to even consider it's mass unless a change in momentum occurs. Due to the spacing of the momentum eigenstates, the mass is just the energy cost associated with changing momentum. The relationship between measured distance and momentum do not always appear to be 1:1. I'm sure you're familiar with X=X0 + vt + 1/2at2. While it would be nice to just talk about velocity eigenstates that span all of space, conservation of momentum deserves due consideration in terms of mass/Higgs fields and the warping of space.

What I am looking for is a quantum mechanics wave description for momentum. Yes, I know that in quantum mechanics, momentum operator p = -i hbar d/dx. I'm just wondering if it's possible to break up space into momentum eigenstates, such that transitions between these states will point to the need for 'mass'.

Steve,

I hope you don't mind. I'm just thinking out loud. If a Higgs field (mass giving field) is unique to each universe, than can linear momentum still be conserved? Or do we have to restrict such interactions? Since only top and bottom quarks are stable, botton is only somewhat stable; truth, beauty, strange and charmed only last for a few nanoseconds before they decay into something else. I have suggested that top and bottom quarks (and other quantum particles stable in our universe), would become unstable in another hypothetical universe with different laws of physics.

To my knowledge, nobody can explain why some quarks are stable but others are not. Quark stability/instability has something to do with the innate characteristics of space-time. As far as momentum conservation, p1 (the shuttle momentum) = m1v1 in our universe. If the shuttle flies into the gateway of a wormhole without any kind of barrier or shield to preserve its laws of physics, then the shuttle's atoms, protons, neutrons and electrons will undergo a change into some other kind of material; or be converted entirely into energy. But will p2 (momentum of the shuttle in the wormhole) still equal p1?

Let's make it easy. Let's imagine a proton in our universe with a momentum of p1=m1v1. It crosses the threshold into the wormhole with altered laws of physics. If c'=100c, then, to solve the problem, a proton's mass is converted into energy. 938Mev/c2. In the wormhole, 1 MeV/c2 converts to 1MeV*(100)2/c'2 = 9.8TeV/c'2. If there is a stable particles in the wormhole at this energy, that's what the proton will become. If there is excess energy, it will probably scatter the proton and violate conservation of momentum.

I suggested that quantum mechanics is independent of which universe is being discussed. I do not know if that includes h-bar, as well.

Yes, of course, you are absolutely right about invariance, stability of the system, etc... It is constraining to try to create the universe out of points, lines, geometric objects, spheres (sorry about that, steve). I want to abandon our preconceived notions about spatial dimensions. I don't believe that there is any absolute space or space-time. Quantum Mechanics is the absolute. We live in a bubbling brew of quantum foam. Out of all of the quantum particles in the foam, only a few different kinds represent the absolute geometric nature of the universe, the virtual photon and virtual gravitons. The rest are engaged in a continual exchange of converved quantities. Space, orientation and direction do not exist until one steps back from the boiling quantum foam. As we step back, conduction bands and higher dimensions emerge. As we step back further and further, 3D space returns to us. Each quantum particle can belong to many different groups the way an overachiever has membership in many clubs. Each "club" may be tachyonic compared to the next.

The
boiling quantum foam I've been thinking about is probably the effect of the highly tuned Cosmological constant. From what I understand, the exansion of the volume of space creates a vacuum pressure; because the Cosmological constant is perfectly tuned, quantum energy is forced into existence as a bubbling of background zero point energy. At least that is my interpretation.

Just by playing around with wormholes and some extremely simplified physics, I discovered Action and the Lagrangian. If I take a worm hole of lenght 2D (D = halfway point); accelleration of g up to the midpoint, and then -g to the other side, where g is a constant; GR inside of the wormhole is ignored to keep it really simple, I came up with some interesting equations.

L=T-V; T=1/2mv2; V=mgx. How long it takes to reach the halfway point is important, so I'm calling that time t1/2.

If my space ship has a mass m, and initial velocity zero, then it's velocity

v(t) = gt. So T(time t) = 1/2mv2 = 1/2mg2t2.

Potential energy V=mgx = mg(gt2)=mg2t2.

For L(t)=T-V=1/2mg2t2-mg2t2, I get L(t) = -1/2mg2t2.

The Action up to the halfway point is S=int(Ldt)=-(mg2/6)(t1/2)3.

Steve,

Yes, I guess I am in another galaxy. Thank you for noticing that.

There is so much to describe and so little time to do it in. I've been discussing hyperdrive technology and wormholes with God. I wanted to understand how the Deity creates universes. God is very handy with mathematics. God likes to use very simple mathematical relationships in ways that stump mortal minds. The Laws of Physics are absolute because they are dictated by God. It takes a significant amount of thought to be able to tie in all elements of a universe into a single absolute relationship. If the speed of light is too high, the universe can fragment into chunks. If the gravitational constant of the universe, G, is too high, everything accerates to quickly. God wants his universe to last many billions of years. He wants a nice, sturdy universe to do things with.

I am infinitely not smart enough to design a universe like God can. It would never occur to me to multiply all of the physics constants that describe a universe, and set them equal to 1. That number would include the number of dimensions, as well. I'm not sure if the speed of light is counted once as a dimension and again as a physics constant. Something like,

4cG(h-bar)(Cosmological constant)=1.

God understands the need and desire to get around the universe quickly. This physical universe exists within hyperspace. Some of the materials that we will need to change physical constants are only available in hyperspace. When the time is right, we will be able to create wormholes by changing the nature of gravity, temporarily. We will choose a star we want to go to. If we can detect AlphaCenturi's gravitatinal field, it's unique signature (something we think we can't do), we can temporarily change the characteristics of that field. In doing so, we will get there in a very short time span. I suspect there may be a hyperspace momentum limit of some sort. God doesn't want us moving planets around the galaxy and rearranging solar systems. I'm still going to use the pendulum idea for this wormhole. A(t) = A0sin[2pi(t/tp)], where tp is the time it takes to cross the wormhole to the other side.

I explained to God that humans have no comprehension of simply changing physics constants to get across space. I could only understand it if we could interact with particles, fields, spin, etc. There are tachyonic materials that exist in hyperspace. They can be made compatible with the four forces.

Look for another charge/field relationship that interacts with mass and coulombic charge.

Hi Steve,

Thank you for your encouragement.

I'm trying to simplify an idea I had. There are some radical assumptions, but here is the physics, very briefly. I have a wormhole/acceleration field that a c'=1015c (c = speed of light; c' = wormhole speed of light). The wormhole spans a distance L between our sun and Alpha Centuari, L = 6 light years. The acceleration field is given by a(x) = a0sin[2pi x/L]. The acceleration a0=1015m/s2.

Trying to calculate x(t), v(t), a(t) and v(x) is trickier than I thought; I may need to use parametric equations. I am treating gravitons as a special kind of tachyonic particle that smears out across space like a vibrating gravity string. But this graviton has strange properties. It's not a particle-wave; it's a particle-space. It has conserved quantities like a particle; when it obsorbs energy, it curves.

A graviton can be transmuted into another particle-space that I will call a wormion. Large numbers of wormions will develop into a wormhole. This wormhole will experience large accelerations given by the equation above. I expect 'wormions' to have a half life of about 60 seconds. One wormion will transport a unit of mass-length; I haven't decided what that unit will be, but it means it will carry a Kilogram over a lightyear of hyperspace. The extreme accelerations are not at all lethal if they are spread over a few lightyears. I am allowing a 10m/s^2 acceleration differential for a 10 meter depth.

The way I'm doing this, hyperdrives create wormholes. I haven't worked out the potential/kinetic energy, yet.

Dear Jason,

To summarize, energy conservation and causality are just two of many reasons why time travel doesn't seem reasonable.

If you want to jump from one brane (that we call space-brane) to another (that we call c'-brane), we assume that we must travel through some sort of quantum barrier.

I am concerned that information may get scrambled in this jump, and that 'entropy' may be the enemy that prevents us from using the c'-brane for FTL travel. Entropy is related to energy and time (via the 2nd law of Thermo) and space and time are related via Relativity. Perhaps it is appropriate that time travel is 'impossible' for one reason, and FTL travel is 'impossible' for a complementary reason.

We need to better understand these barriers between the space-brane and the c'-brane. Can we model these branes? Can we model information transport across these branes? I think you should pick at the problem until it beats you or you beat it. Along the way, you will probably learn this week's lottery numbers. Please remember your old buddy, Ray, when you are super-rich.

Have Fun!

Dear Ray,

Can I get a scoop of each?

Finally, someone understands what the issues are! I'm hoping to avoid brane-jumping by generating a field/shell/bubble in which the spaceship (made of space-brane particles) is enshrouded by the FTl bubble (c'-brane field). The field has to be generated using a material that exists in both the space-brane and the c'-brane. Both branes exist in the same space, but are non-compatible. I want to find a way to make them compatible. That is why I asked about charged tachyons. Probably colored tachyons will be necessary too.

I have a question about charged tachyons. Charge manifests electric and magnetic fields; virtual photons are supposed to make electric and magnetic fields operate; photons (virtual or otherwise) move at the speed of light. I expect tachyon particles to become c'-brane particles. Have you looked at how this will effect your theory of charged tachyons? Since permitivity scales electric fields, permeability scales magnetic fields, it seemed reasonable to me to use electric and magnetic flux when trying to cross a space/c'-barrier. In truth, I expect this to be extremely awkward (thus we don't observe it).

By the way, I totally agree that information content gets scrambled when crossing a space/c'-barrier. That is why I want to generate an FTL field instead of jumping to the c'-brane. The field is supposed to be null inside of the spaceship (so it doesn't disintegrate); it should extend only as far as necessary. Thrust has to be translated to the c'-brane, with equal and opposite force applied to the FTL field. The FTL field accelerates as a c'-brane object. The spaceship has zero velocity with respect to the field because it's generating the field. Whatever it takes to get the space/c' mixture to remain stable (behave itself), is going to tell us whether this will or will not work, and why.

What do you think?

Ray Munroe wrote on Nov. 24, 2009 @ 21:47 GMT
Confining tachyons may be tricky. Perhaps we could use color charges to bind a tachyonic quark to an unstable pion, and manufacture a 'baryon' or 'meson' that is part tardonic matter and part tachyonic matter.

Otherwise, tachyons travel faster than light, and a photon couldn't confine them (unless an electromagnetic field contains so many photons that the tachyon will bump into a photon more often than not).

If we could manipulate gravitational fields, we might use those to contain our tachyons. After all, the 'action-at-a-distance' behavior of gravity implies a faster speed than c.

So we want to 'cloak' our spaceship in tachyonic matter, disappear to the spacetime world, and trick hyperspace into admitting us onto the c' superhighway.

Good Luck!

Ray,

Bingo! Consider this creative thinking. Have you ever heard of virtual computers? If a faster Pentium 4 processor can mimic the information capabilities of a 486 processor (from the early 1990's), it's only reasonable to wonder if a c'-brane can represent the entire spaceship, crew and contents as a c'-manifestation. I am counting on the No Clone of Quantum States theorem to protect us from duplication. Obviously, I also expect mechansistic processes to proceed without disruption. The translation process has to be thermodynamically observant. I just want to make sure that the field and field generator don't jump to hyperspace, but leave the rest of the spaceship behind. Remember that quantum entanglement has instantaneous-ness built into it.

OK, maybe that sounds a bit magical. But we need to look at it this way, it will help us to figure out what the real issues are, what questions we need to ask, and what experiments we need to conduct.

Pions are unstable because of weak forces, but they give off neutrinos and muons. I think some amount of dark matter is considered to be neutrinos. Neutrinos might be confined to the space-brane, or they might intermingle with a c'-brane as well. There is still a lot we don't know about them since their coupling is so minimal.

If tachyons are just c' particles, then they can be bound with c' electro-magnetic forces/fields. I just don't know if c' electric/magnetic fields/charges are related to each other. I'm hoping that they belong to the same set of something more generalized. A space brane and a c' brane have to share some common ancestry, something in common.

In your paper "A Case Study" you do have a table with what might be called chromo-tachyons. I am not exactly sure what these color indices refer to. in your hypercolor paper you have the 7-fold g_2 color diagram. As I have been indicating, the centralizers g_2 and f_4 act in a sort of cojoined fashion, where the F_4 contains the gravitational content. Closed strings approach the region of enormous tidal forces in a black hole interior and transform into open strings. The gravitational modes in a left/right setting are transformed into tachyons. In this setting with the G_2 holonomy, these tachyons would become a sort of technicolored tachon. The condensate of these open strings on the M_2 brane would then have a form similar to a quanrk-gluon plasma.

It means that F_4 is the largest group which defines the 24-cell or tetrahedrachoron. F_4 in a quotient with D_4 ~ SO(8) and B_4 ~ SO(9), defines some of the structure of the Fano plane. Further SO(8) is contained in SO(9), of 28 and 36 dimensions respectively, out of the 52 in F_4. SO(8) contains SU(4) in a Clifford basis (look at what I wrote onClifford algebras yesterday and today. Indeed SO(6) ~ SU(4) and in a Wick rotated system we then have SU(3,1) or SU(2,2) ~ SO(4,2), where we in the second case have twistor structure and AdS_5 spacetime.

Solid state uses arrays of atoms to provide the repeating pattern of wavefunctions necessary to derive conduction bands, etc. Yes, of course we know all that. You did the very same thing with tetrahedrachorons to construct 4D space-time. I find it ironic that while the Scwartzchilde sphere may never be observed, you have, in effect, created an aether using wavefunctions, that is space-time compatible.

I agree that these tachyons have a foundation in the behavior of quantum gravity. I have all four "colors": red, green, blue and white (plus anti-colors) which mimics the quantum numbers of quarks and leptons - with different electric charges and improperly defined intrinsic spin.

I know you are looking for a triality symmetry for your E8's. I don't think this is it. I think your E8's are more closely involved with gravity and/ or supersymmetry.

Four colors would imply an SU(4) group, or extended QCD. Quarks and gluons come from the fundamental 3 representation and the adjoint 8 representation of SU(3). I was thinking primarily of SU(3), which is the maximal subgroup of G_2 and decomposes as SU(3) + 3 + bar-3. I suppose one could consider this with SU(4) for the 4-irrep for quarks and an adjoint 15 for the gluon (like) fields

Dear Lawrence,

I'm sorry - I don't mean to confuse the issue. "Color" is a phenomenon based on the rank-2 groups: SU(3) and G2. "Hypercolor" is the 2-dimensional triangular lattice defined by these gluons, quarks and SUSY partners.

If you study my Georgi-Glashow SU(5)/ Tertrahedral Conjugacy symmetries, you realize that the X and Y bosons of Georgi-Glashow can be represented by three dimensional vectors that connect the 4 points of a tetrahedron, where one traingular face of the tetrahedron is the SU(3) (red, green, blue) triangular lattice mentioned above. I call the 4th point in the tetrahedron "white". Pati-Salam Weak uses a new color "violet". I'm not certain which designation is more appropriate. This four-fold color symmetry is only valid at high enough energies (low enough X and Y masses). Please see Table 10 of the "A Case Study" paper for more details.

In there I argue for there being tachyon condensates, which as you indicate are chromo-tachyons. If so then maybe a simple demonstration of G_2 physics can be made with the aut(O) and F_4. Then the M2-brane is a sort of dual system to quark-gluon plasmas. It sounds as if a paper could be written up on this which is sufficiently focued on this physics.

Photons have built in eletromagnetic fields which allow them to become solutions to the Schrodinger equation, neutrinos do not; are neutrinos fundamentally incompatible with the Schrodinger equation? Yet they have spin. If they have spin of 1/2, thus they are fermions. If they have spin, they have to be electromagnetically interactive. There can't be solutions to the Schrodinger equation. What QM equation are they solutions to?

Dear Jason,

Neutrons and neutrinos are both electrically neutral. A neutron is composed of two down quarks (charge -e/3) and one up quark (charge 2e/3), so a small variable dipole-like electromagnetic field might exist in principle.

The neutrino is color neutral (net color "white") and electrically neutral (net charge 0e), but does react via the Weak nuclear force (its how we can detect them at all) and probably via Gravity (which might allow neutrino oscillation from muon neutrinos into electron neutrinos and vice versa, although there may be a question about magnetic interactions).

If right-handed neutrinos exist (as neutrino oscillations and a non-zero neutrino mass might imply), then we can use Dirac's equation to describe neutrinos. If neutrinos are strictly left-handed, then we can use the simpler Majorana equation.

I've been interpreting mass as some kind of a "lag time" associated with the speed of light; as if the laws of motion are implemented with light somehow. To me, the speed of light is like a CPU processor speed, and the interacting particles are sort of like subroutines, the mass would be the number of clock cycles, all metaphorically speaking. However, if they find any of the Higgs particle, doesn't that shoot down my "lag time" theory? If they find it, so be it. I'm just not sure if their Higgs field theory, and my "lag time" theory are mutually exclusive.

Dear Jason,

If they are "particles", we should be able to bind these chromo-tachyons to pions. But if they are lattice defects that are "dual" to Spacetime, they may behave like some strange soliton state.

I think mass and gravity originate in hyperspace and are weakly communicated to our Spacetime via geometry. This might explain: 1) why mass doesn't seem to be quantized (I think mass quantum numbers are quantized in hyperspace, but we see a distorted projection into Spacetime), 2) why Gravity is so weak (I think WIMP-Gravity is stronger on the WIMP-Gravity-brane but few of these field lines extend out into our Spacetime. Gravity is weak because it is spread out over 11 or 12 dimensions, whereas electromagnetism is only spread out over 4 dimensions).

I need to think on the meaning of "lag time".

By "lag time", I don't mean time. In a scattering event, the laws of motion work as fast as they can, to exert all of the necessary forces to change the vectors of the particles. A more massive particle is an indication that their is more "to get done"; if the speed of light were faster, the change in direction could occur more easily. Does that sort of make sense?

I had considered the possibility that wave functions might be FTL in nature, but are required to slow down to the speed of light to properly interact with the laws of motion. I guess that's another way to say what you just said: project from hyperspace into space-time OR forced to slow down to properly interact with the laws of motion. Not a huge difference...

The tachyon can't exist as a free particle, but must be confined in some ways. In a condensate the tachyon strings have open ends attached to a M2-brane and are then "confined." There is a QCD-like logic to this with confinement = no free quarks.

I needed to use some kind of material that has components of both regular space-time and also components of a c'-brane/hyperspace. It sounds like a chromo-tachyon would allow me to do this by creating protons/neutrons with tachyonic properties. I could have tachyonic-iron, for example. I don't need free quarks, I need a way to interface between space-time and hyperspace.

Dear Jason,

These chromo-tachyons cannot have free quarks. They must be bound into colorless mesons or baryons. If we had a "pion" or "proton" or "iron nucleus" composed entirely of chromo-tachyons, it would immediately fly off to infinity or the nearest black hole (unless we could confine it electromagnetically or gravitationally). I was hoping we could manufacture tachyonic pions at a supercollider and slam them into tardonic pions and hope for a meson or baryon that had chromo-tachyons and regular quarks. This is pure speculation.

If Lawrence is correct about black holes converting closed strings into open strings and producing tachyons, then we may have to travel to a black hole to find our chromo-tachyons. This sounds similar to my ideas from last week when I said that there must be a serious "plug" that prevents Spacetime and Hyperspace from merging. One of these "plugs" could be a black hole singularity.

The tachyons might be similar to quarks in a chromo-dynamic sense. They would also be confined in black holes, or the M2-brane as the quantized singularity of a BH. There is then some possible aspect of black hole complementarity here. The observer who measures a string falling to a black hole from a distance observes a different set of physics from the observer who falls in with the string. The string from the perspective of the distant observer will slow down and red shift is observable transverse modes, while the longitudinal modes grow so the string covers over the horizon. The string according to the infalling observer displays nothing usual in its dynamics until it approaches the singularity. There an string is observed to stretch and transform into an open string. The gravitons modes in the so(24) symmetry transform into tachyon modes, and these open string connect to an M2-brane.

These two views of the string are analgous to performing spin measurements with a Stern Gerlach apparatus along different directions. The S-matrix description of the string in the two configurations involves incommensurate observables that are not simultaneously diagonalizable.

The QCD-like nature of a colored tachyon may then be some duality to QCD. The possible observation of AdS-black hole like physics at the RHIC might then reflect how chromo-dynamics can exhibt this duality.

Dear Steve,

Did you want to know if I think that rotation causes gravity? I know about gravitons and I've heard about these mini-black holes. In truth, I'm not exactly sure why large accumulations of mass-energy would cause an attractive force that we call gravity. Rotation is a kind of angular-energy, and if large enough, would contribute to gravity; although realistically, I can't think of anything that could spin fast enough to generate a gravity field; anything spinning that fast would overcome F=mv^2/r and fly apart. If there is a connection between rotating spheres and mass, it escapes me.

Ray,

We're not having pecan pie; I am so jealous. Make sure you save room for turkey.

I was always taught that quarks come in groups of three (5), never ever by themselves. What I really wanted to do was mix in chromo-tachyons to create hybrid hadrons (mesons and baryons) that would not fly off to infinity. But there is a slight problem with our plan. I need a tachyonic lepton if I want to generate some kind of an interface field. Leptons (e.g. electrons) are used to generate electromagnetic fields complete with virtual photons. I would need a lepto-tachyon to generate FTL virtual photons. Didn't you mention something about that?

As for generating chromo-tachyons or lepto-tachyons, I am hoping we'll eventually be able find these occuring naturally. I hope we don't have to pull them out of black holes; I'm kind of hoping we'll find them in abundance in hyperspace. Perhaps initially, we'll need to use proton colliders to create them.

Dear Jason,

I also have lepto-tachyons, but those should immediately fly off to infinity or the nearest black hole - unless we can confine them with electromagnetic fields - I'm skeptical of this part because tachyons travel faster than photons, unless we can temporarily confine the tachyon with a large number of photons that the tachyon must bump into as it makes its escape.

Color theory works like this - we have three colors: red, green and blue; and their anti-colors: cyan, magenta and yellow. All "colorless" or "white" combinations of colors are stable. This includes baryons which are three quarks of different colors (red, green & blue) or different anti-colors (cyan, magenta & yellow) or mesons which are a quark and its anti-quark (red & cyan) or (green & magenta) or (blue & yellow).

If we had a normal pion made of a red up quark and a cyan anti-up quark, and slammed a tachyonic pion made of a red tachyon and a cyan anti-tachyon into it, we might be able to manufacture two hybrid pions made of 1) a red tachyon and a cyan anti-up quark, and 2) a red up quark and a cyan anti-tachyon. I still think our best bet is a black hole.

Yes - We had turkey and lots of side dishes and desserts.

Dear Steve and Georgina,

I don't think that rotation has much to do with Gravity. The graviton has intrinsic spin of 2, and a spinning black hole has a modified horizon (versus a non-rotating one) because centrifugal acceleration affects the net acceleration produced by the black hole. We don't understand all of the root causes of Gravity, but I think that confusing gravity and rotation is not a fruitful path.

Rotation is related to gravity through the equivalence principle. The pseudo-force or centrifugal force is equivalent to nongeodesic motion in a gravity field. Combining the two is complicated. Orbital motion by Newtonian mechanics equates the centripetal force with gravity. For a relativistic case the centripetal force becomes complicated, and in face is reduced as one approaches r = 3m. At r = 3m the centripetal force disappears, and this is the photon sphere. This is a radius at which a photon can exist in an orbit around the BH. For r < 3m, but greater than 2m the centripetal force is no longer inwards but out. This means that in order to maintain a circular orbit in this region some additional force is required. There are no stable orbits in this region, and if you have rocket power you had better turn it on. Of course beneath r = 2m you are sunk.

The business of time not existing is a bit strange. If we go back to Newton's second law you have F = ma telling us that a dynamical quantity (force) equals a kinematic quantity (mass) times a geometric one (acceleration). The equation is then a bit odd, for the two sides of the equation involve quantities which are not existentially or ontologically equivalent. Physics has been stuck with this issue ever since. So what do we do? We stick with it, and the acceleration d^2r/dt^2 is a second order ratio of geometric quantities, length and time. We can measure these with rods and clocks. We don't however hold a clock interval in the same way we can hold a rod which codifies a length. So time seems a bit stranger still. Yet we have velocity, and in particular the speed of light which permits us to convert between length and time intervals. This also provides a symmetry principle which transforms between length and time depending on transformation between frames.

The ADM approach to general relativity slices spacetime into space plus time, and spacetime is foliated by spatial surfaces. The Lagrangian is NH = 0, for H dependent on extrinsic curvature terms on the spatial surface. The quantum version of this is similar to a Schrodinger equation without the time derivative. This is a part of the motivation by Barbour to say that time does not exist. Yet this apparent lack of time is due to the inability to equate diffeomorphisms of spatial surfaces with a time in a consistent way. Hawking’s sum over geometries or spacetimes involves these notions, but many mathematicians have difficulty seeing this as firmly established.

Lawrence,

You said "The business of time not existing is a bit strange." Possibly true but that depends on how you choose to think about it.

I think...

Force is the capacity to do work, that is change position of matter or particle within space. Inertial mass is the result of the bodies current trajectory through (quaternion 4D) space. Acceleration is the change in that trajectory.

Why is it multiplied? The change is not just change in 3D vector trajectory that can be added or subtracted from current vector motion but incorporates change in the relationship of 3D motion to (spatio-energetic) 4th dimensional change in position.

I sometimes try to use the concept of nested spherical spacial surfaces or planes. Though I actually think the space is continuous just as it is within 3D space and not physically divided up. The different surfaces just representing different energy levels, not different times. It is the energy difference that makes these other spatial planes inaccessible not any problems of time paradox or causality. The 4th dimension is then just the dimension in which the stacking exists. It is not within 3D space because that (3D space) is just one of the stacked surfaces.

I took a quick glance at ADM on Wikipedia. You are a veritable mine of information!

I don't think physics is in the business of telling us whether something like time exists. Time is BTW analogous to the electric field in electromagnetism. Similarly with fields in general we don't directly measure them, but infer them through how we measure the motion of particles. Fields as well as space and time are geometric elements we think according to. A good working model involving time and space, such as relativity, does give us a sense that what we are working with are not figments of our imagination. In a sense we can say they are real enough, even if we can't directly measure them, but only infer them through comparisons with rods and clocks. In a sense that approach works well enough.

Force is a dynamical quantity, and it is related to energy through the work theorem W = ∫F*dx. These are more dynamical, though curiously we measure the influence of a force geometrically. The weight of a body is found by how it distends a spring, so that length of distention is a measure of weight = force = mg. There are similar funny aspects to physics, and physics will probably never be as purely self consistent as mathematics. After all mathematics involves relationships between abstract objects, while physics does tell us something about how the world will behave if we tweak it in some way.

I gave thought to the idea of time not existing, or that it is an emergent property on a large scale. The problem is that for this to be the case we also have to say the same thing about space. It makes no sense to me to say time has no existential aspect to it while space does. I also think that the ideology of time not existing is a sort of interpretation of physics, juxtaposed with other interpretations such as block time. Relativity, quantum theory and statistical mechanics have various interpretations. Yet none of these rises to the level of being a real theory which tells us something definitive about the world. As theories they are really ineffective. So I can’t seriously entertain notions of time not existing, just as I think block time is a sort of interpretation which should not be upheld as a theory which can be supported by empirical evidence.

As for rods and clocks, what happens if we measure everything with lasers and points light sources? We can always calculate red shift/blue shift to determine velocities; we can always calculate light intensity to determine distance. For more exotic physics such as black holes, gravity, FTL events, I trust lasers and light sources more than I trust rulers and clocks. Since I know I can always modulate lasers and light sources, I know I can discover overlooked areas of physics by asking what happens to the information content of a modulated stream (a song, a video, etc..). For example, I can have a buoy or satellite in a decaying orbit around a black hole. Let's say it has equipment that can receive RF signals I send it, record them, then transmit them back to me at some safe distance. In whatever way I transmit my favorite song to the bouoy/satellite, I suspect the frequencies will be shifted as the RF waves arrive at the buouy which is deep in the gravity well; that will probably distort the signal causing information loss. When the song I transmitted is transmitted from the buouy, there will be more frequency shifting, which will distort the signal even more. Does this constitute loss of information content? Probably not. But it's worth considering.

Lawrence,

I agree that relativity is a good working model. However it does also leave a lot of foundational questions unanswered. So I will say that whether it is good enough depends on whether you are satisfied with leaving those questions unanswered or not. Accepting that the universe works according to God's will works well enough, if you are fully satisfied with that explanation.

We can observe the amount space that an object occupies, that is its volume. Therefore it is scientific to use the concept of space in a model. Everything that we think of as time passing is the change in position of matter in space. The moving of the celestial bodies, growth and ageing of living organisms, the moving of the hands on the clock and the swinging of the pendulum. It is all spatial change experienced as time. Changes in spatial position are energy changes and vice versa. These can be interpreted as time passing but time has no independent existence outside of that. There is no need for time in the model. Space and change in position, which is an energy change, is all that is required. Though to correspond with relativity and explain gravity it is necessary to have a 4th dimension. Which is not time itself.

Time as currently used is more than just a geometric element. It is a muddle of a number of different mental concepts. That is why it leads to strange, paradoxical, nonsensical, and to me wholly unacceptable, interpretations. These interpretations amount to fantasy not science. The arrow of time, causality and non reversal of time can all be accounted for by 4th dimensional change in spatial position, which is a continuous energy change. In the context of this explanation I do not think it strange that force can be measured geometrically. The meaning of dynamic is altered together with the alteration in perception of time.

Newton's first law tells us that a body in free space and not subjected to a force remains in a constant state of motion. This tells us a couple of things. The first is that inertial frames are the optimal choice for observing physics. If you are on an accelerated frame you will not observe the mass to remain on a constant state of motion, or moving along a line. The other is that since the momentum (p = mv) is constant and F = 0 then the energy change or work done on the system is zero E = ∫F*dx = 0. So energy change is not necessarily germane to the issue of motion. The body at a constant velocity does have a constant energy E = 1/2mv^2, dE = mvdv, and for constant velocity dv = 0 and dx = vdt.

Energy and time are related to each other as conjugate variables, just as momentum and position. In the latter case this is known with the Hamiltonian formalism of classical mechanics. It also applies for both these cases with wave mechanics and Fourier transforms.

Time is something which is built all around us. Even the structure of language is very much built around time, present, past, future, plus perfect and so forth. Time is an odd quantity for we can’t hold it in our hands as such. Yet we can demark it with clocks and organize activity according to time. As such time is at least “real enough.”

Lawrence,

you said "So energy change is not necessarily germane to the issue of motion." I do not agree with that statement. Energy change is completely tied into motion. Motion requires a change in spatial position. Every change in spatial position is an energy change. As motion is occurring within 3D space and occurs "over time", there is both 3D and 4th dimensional component to that motion. Everything is in continuous motion. Even a body "at rest" has energy because of changing quaternion spatial position. Even when there appears to be no net energy change there is still energy change along the 4th dimension which is a continuous loss of potential.(That is the energy input that drives the increasing development of the universe.)

Energy is nothing but changing quaternion spatial position.It is the "how much" measurement of that quaternion spatial change.

Time has been built into mathematics. That is not a problem so long as there is acknowledgement of what that time component actually represents in objective physical rather than subjective(experiential)terms. The use of time is required because there can be no direct 4th dimensional measurement. So a continuous regular change observed in 3D space can be used to represent it. It is an approximation. There can be minuscule variation from that regular change which leads to observed time dilation. It can be hypothesised that when huge energetic events occur there can be correspondingly large variation from the expected regular change. So astronomical bodies may sometimes not be calculated to exist in the positions expected from steady evolution over time. It is the energy change that is significant though it is interpreted as a temporal effect or anomaly.

Social convention and linguistic traditions should not determine how science objectively models reality. If everyday language is inadequate then new terms and their definitions are required. Just as if current mathematics is inadequate then new mathematical forms are required. Everyday usage of the term time is a problem because it is not scientific usage but a muddle of different concepts explaining subjective experience and held as common knowledge. That gives rise to explanatory frameworks that are limited by this misconception.

Georgina,

If we drop "social convention and linquistic traditions", we hobble science in two ways. First, the public loses touch with the importance of physics, so they won't bother buying books or thinking about it. This has the effect of making it harder to ask politicians to vote for funding for important experiments. Second, it makes it that much harder for physicists to match up physics with "reality". There is already a problem with physicists not being able to comprehend the physics or relate it to common experience. That's why some people can't tell the difference between FTL and time travel. If you remove time completely from physics, it becomes nothing more than a meaningless Rubick's cube of pretty symbols. Another example of this is the "Holographic Universe". It sounds like such a cool and mysterious concept. It means that physical matter can be represented as information content on the surface area of a blackhole, hypothetical or real. Can anybody really tell me what "information content" is?

Let's do a better job at tying physics to reality and everyday experience before we remove the very experiences, like time, that people understand.

Jason,

People in general do not understand time. My experience tells me that -most- people don't think about -what- it is at all. I have previously given terms for the different concepts of time that are currently muddled together in common usage.

Science is not (and should not ever be) just about entertaining the public, selling books and journals and getting "political" approval and funding. Just because something is appreciated and "understood" by the masses does not mean that it is closer to the objective truth or more scientifically valid. All sciences have particular terms for specific meanings that can be translated into everyday language for wider comprehension. So that is not a problem.

I am not talking at all about removing experience of time or the use of time either in everyday life or within scientific investigation. Just using it in a way the recognises what time -represents- within physics rather than the current misconceptions.

Lawrence,

with respect. Understanding that which is taught and considered basic is not necessarily the same as unconditionally accepting its validity.In order to answer the foundational questions some foundational changes must be made, however inconvenient.Just sliding the same old tiles around every which way will not solve the puzzle.

It is space and energy that are intimately and inextricably woven together not space and time. This can be represented by a quaternion arrangement of 4 spatio-energetic dimensions. Every change in spatial position is an energy change. There can be no change in spatial position without a change in energy because these are the same phenomenon.Just as when using space-time there can be not change in spatial position without a time interval in which that change occurred. That is why you said "A particle moving in free space does not change its energy".You are not taking into account energy change along the 4th dimension because you are substituting for it with time.

A gravitational field can be regarded as an increase in universal potential energy gradient which gives an aforeward ("forward" but not along a vector dimension) change in spatial position along the 4th dimension. Time dilation also occurs because time is being used for measurement. It is telling us that there is a change in the gradient of loss of energy. That it is not constant through out space but varies according to the distribution of mass. It is not telling us about the stretchiness of time.In my opinion.

I can only advise that you take some time to learn basic physics. A body moving free of any force has a constant energy. I am not talking about quantum mechanics where there can be fluctuations in the motion of a particle around a straight line and associated quantum fluctuations in energy. In basic classical mechanics a bovy moving with v = constant has also constant energy.

I was watching some videos about dark matter and dark energy last night. They do a very good job at explaining what is happening. Dark energy is causing the expansion of the universe to accelerate. We've discussed all this stuff before, including the "expaning balloon" metaphor. Do you have any thoughts on dark energy?

Lawrence B. Crowell wrote on Nov. 30, 2009 @ 19:57 GMT
Dark energy is a constant Ricci curvature on a spacetime, which is associated with the cosmological constant. It is frequently interpreted as due to the vacuum energy and negative pressure from quantum fields. It then describes the constant stretching of spatial surfaces by sliding points on those surfaces apart. This can apply to a flat spatial surface as well, and for various reasons this is the optimal spacetime. The flat space or k = 0 model obeys holographic principles. This dark energy is also what drove the inflationary period of the universe, but where the inflationary parameter Λ was adjusted or renormalized to a smaller value with the end of inflation, and is now what we call the cosmological constant. If you look at my essay I sketch how this process is potentially due to a quantum phase transition associated with a quantum critical point. We are now in this latent phase with a form of what might be called eternal inflation.

Based on current theories, or hypotheses which are not as yet well tested, dark matter is likely to be the supersymmetric partners of known elementary particles. The lowest mass particle is the neutralino. This is a condensate of the super partners of the photon, Higgs and Z particles. Data from Fermi and PAMELA indicates the production of gamma rays from near the galaxy center, where dark matter may be most present. This would then be potentially due to neutralino annihilations. The data suggests the source of these gamma rays may be particles in the ~ TeV range of mass-energy. If so these should then appear in the LHC as it ramps above the 10TeV beam energy.

Dear Lawrence,

I wonder why these superpartners would be invisible? I would have guessed that dark matter, which has no electromagnetic interaction at all, would have to be completely chargeless as well as unmoved by electric/magnetic fields. As such, they shouldn't even have spin because spin makes them magnetically interactive.

Dear Jason,

The Lightest Supersymmetric Particle (LSP) is expected to be a Neutralino - a neutrally-charged mixed quantum state of the spin-1/2 photino, Zino and Higgsinos. Thus, we expect it to interact in Electro-Weak interactions. Perhaps its interaction is comparable to a neutrino - mostly neutral but it still counts as mass, momentum and energy. We expect conservation of 'R-Parity', and thus the LSP is expected to be stable (unless it annihilates with another supersymmetric particle).

Hi Ray,

I'm confused by dark matter. If it were dust and debris, wouldn't it be so thick that it would cause orbits of planets around stars to decay? But then, wouldn't this dust radiate black body radiation? Is it possible that 26% of the total gravitational mass of the universe is just dirt/dust/debris and ordinary matter that just doesn't put out enough light for us to be able to distinguish it from the stars at the center of galaxies?

I guess my confusion is this: either dark matter is just too dim to be observeable, or else it really is electromagnetically invisible at all frequencies. If it's really invisible at all freqeuncies, then it has to carry zero charge and zero spin for that matter. Right?

But for that matter, a graviton has spin 2. Doesn't that mean that gravitational fields, if they really are implemented by gravitons, should emit light in the presense of a magnetic field?

Please let me know if I am running amuck.

I looked up spin in wikipedia. Spin just represents quantized angular momentum. I was incorrectly assuming it represented a magnetic dipole. Although, if spin does not ALWAYS represent a magnetic dipole, then how can spin be exchanged if there is no coupling? In other words, if a particle is created that has spin, but no charge, how can it ever introduce that spin into another reaction if there is no way to exchange the spin?

A charged spinning particle has a magnetic dipole. There is a quantum result on something called the g-factor where g = 2.0. Quantum electrodynamics refines this prediction further due to something called a Lamb shift, so g = 2.002... or so.

The neutralino would appear to be a sort of massive neutrino. It is a condensate with the Z-particle, which is the electrically neutral but carries the equivalent of a charge for weak interactions. This is because the weak interaction is non abelian. The supersymmetric partner also carries the weak charge.

There should also be super partners to the gluon, or the QCD vector boson, called a gluino. So glue-balls of gluons in a colorless plasma should also have superpartners as well. These will be very massive and probably unstable.

@ Jason - "I'm confused by dark matter. If it were dust and debris, wouldn't it be so thick that it would cause orbits of planets around stars to decay? But then, wouldn't this dust radiate black body radiation?" Yes, if we pulverize normal 'baryonic' matter into dust, we still have atoms with electron orbitals. If you excite an electron with solar radiation, it will absorb and emit characteristic atomic spectra. And yes, any substantial 'unseen' mass within the planetary orbits can cause 'drag' that affects the planetary orbitals.

@ Jason - "Is it possible that 26% of the total gravitational mass of the universe is just dirt/dust/debris and ordinary matter that just doesn't put out enough light for us to be able to distinguish it from the stars at the center of galaxies?" Possible Dark Matter candidates are Brown Dwarfs (like Jupiter), the LSP (like a massive neutrino that interacts via the Weak and Gravitational forces), WIMP's (Weakly Interacting Massive Particles - recall I had a WIMP-Gravity), and MACHO's (Massive Compact Halo Objects). I would recommend that you read Gordon Kane's essay and PAMELA references. A few years ago, Prof. Kane hired an old friend (and grad school office mate) of mine, Mike Brhlik. Mike and my doctoral thesis advisor, Howard Baer, worked on the phenomenology of the LSP as Dark Matter. Quite frankly, until we understand Quantum Gravity and the Cosmological Constant, we may not 'know' as much about Dark Matter and Dark Energy as we think we know.

@ Jason - "I guess my confusion is this: either dark matter is just too dim to be observeable, or else it really is electromagnetically invisible at all frequencies. If it's really invisible at all freqeuncies, then it has to carry zero charge and zero spin for that matter. Right?" I might agree to electrically neutral - I'm not sure you can make the generalization of zero spin (Jupiter doesn't have zero spin).

@ Jason - "But for that matter, a graviton has spin 2. Doesn't that mean that gravitational fields, if they really are implemented by gravitons, should emit light in the presense of a magnetic field?" If you are obtaining this result based on Classical Electrodynamics, consider that we may need to apply both Quantum Gravity and Quantum Electrodynamics. I think Bryce DeWitt made the argument that a spinning electron should interact with the curvature of the Universe, and this might allow interactions between photons and gravitons. Also, my Grand Unified Mediating (GUM) Boson treats photons and gravitons as separate quantum states, so perhaps conversions of one propagating boson into another is possible.

So it sounds like dark matter is not expected to be baryons or leptons; instead, it's expected to be super symmetry partners: WIMPs MACHOs, photinoes, etc. I'm not sure I believe that brown dwarfs can make up a significant amount of dark matter. The center of galaxies are very dense places. If there were brown dwarfs there, it wouldn't be long until they crashed into a star. or were ripped apart by gravitational "rip tides". They really wouldn't be able to maintain nice stable elliptical orbits for billions of years because there is so much to run into. They would either be absorbed into a star/blackhole, or in any event, they would be ripped apart into a gaseous cloud.

In the search for a theory of quantum gravity, perhaps we could also say that we are looking for a theory of quantum-space. When I contemplate this, I keep running into the question: what are forces? Then, I notice something funny:

Charges: opposites attract/like charges repel.

Mass/Gravity: like masses attract/opposites (if they exist), should repel.

Charges use quantum waves (photons) to achieve attraction/repulsion. However, mass/gravity uses curvature of space (time) to achieve attraction (repulsion). It looks like space itself and wave-functions should share some fundamental relationship, like lions and cats.

The centers of galaxies normally are very dense, and many could be black holes. Outside of these galactic centers, we often look for cold exotic matter (WIMP's/LSP) to explain the 'unseen' mass.

What are forces? What are dimensions? What is space? See - I can ask a lot of funny questions also. In my model, force charges relate to dimensions. We only see 3+1 dimensions because of spontaneous symmetry breaking and dimensional collapse. We cannot directly observe Quantum Gravity because of broken symmetries and dimensional collapse, thus Gravity is transmitted from Hyperpace (where it is strongest) to our Spacetime via broken geometry. I do wonder if there is a repulsive gravity. This might be possible for WIMP-Gravity. In some respects, anti-matter is most consistent if it has negative mass (and then we would use E^2=m^2c^4+p^2c^2, not E=mc^2), but I don't think gravitational repulsion has ever been observed. I don't think it is coincidence that we only have a reasonable understanding of four force charges: Strong g_3, Strong g_8, hypercharge, and weak isospin; and four dimensions.

Dear Ray,

I agree that gravity should be stronger in hyperspace. I'll give you my reasons if you give me yours. That might help explain more of the overall picture.

You said: "...I don't think gravitational repulsion has ever been observed. ". The universe is expanding because of dark energy. How is dark energy not equivalent to gravitational repulsion? Gravitational repulsion has been observed indirectly. It is true that anti-gravity has not been observed; is that what you meant?

You said: "What are forces? What are dimensions? What is space?" Those are the kinds of funny questions that we all need to be asking. You choose to work with higher dimensions and symmetry breaking. I think Michelson/Morley poisoned the whole idea that the laws of physics are implemented via some medium. So now, we have to use strange words like p-brane to talk about what we all suspect: that light is an oscillation in some kind of undulating medium. The laws of motion are subordinate to this motion; but the connectivity is accomplished by the absolute velocity of photon wavefunctions that create a space-time matrix; like a GPS system with 10^100 sattelites. I don't know what causes the photons to always travel at a velocity c, or what is ultimately causing them at all. But let's set that aside for the moment. We do know that whatever gravity is, it tugs and distorts this space-time 'matrix', and causes time to run slow in some places. My point is that we need to set aside our anxieties about aethers, and figure out the properties of "quantum-space". If you say that symmetry breaking is an obstacle to testing these other dimensions that make up "space", then I request: can you explain to me your understanding of what (spontaneous) symmetry breaking is?

Yes - Gravitational replulsion is the most common interpretation of an accelerating Universal expansion (Dark Energy). I wasn't thinking! I have my own 'crazy' ideas in Variable Coupling Theory (my book), but I need to consider 'Einstein's mistake' more seriously - Lawrence is pretty serious about it, and I should be.

I think symmetry-breaking is relevant. Certain SU(N) algebras have interesting properties and crystalline analogies, such as SU(5), SU(7) and SU(11). While in graduate school, about 15 years ago, I told many of my friends that I was working on a SUSY SU(11). I was playing with Quaternions and Octonions as well. I just never took it seriously that these higher-ranked algebras implied more dimensions. I think other important SU(N) algebras include SU(15), SU(19) and SU(29) (with minor interest in SU(9), SU(13) and SU(27)). If rank and dimension are equivalent, then the most interesting numbers of dimensions are: 4, 6, 8, 10, 12, 14, 18, 26, 28, etc. We need to understand how these symmetries break (such as Higgs mechanism), and how these dimensions collapse (such as numbers of dimensions and geometries). Now we are full-circle back to the infamous aether - only we have 'unseen dimensions' rather than an 'unseen medium'.

If you have two masses m and -m (positive and negative) you have a curious situation. For the positive mass the Newton's second law gives

ma = -G(-m^2)/r^2,

so the positive mass is accelerated away from the negative mass by

a = Gm/r^2.

Now for the negative mass you have

-ma = -G(-m^2)/r^2,

and so the negative mass is accelerated towards the positive mass by

a = -Gm/r^2.

This is because the "charge" for gravity, which is mass, is also in the F(m) = ma. So the -m and +m will fly away with an acceleration and maintain a constant distance from each other. This sounds somewhat paradoxical, yet in a way since the total mass is m - m = 0 there is a net nothing accelerating away.

Anti-particles are negative mass-energy states E = -mc^2 that fill the Dirac sea. If you give a state in that "sea" 2mc^2 amounts of energy you create a positive mass anti-particle, with opposite quantum numbers such as charge. So it is not expected that anti-particles which are created in the lab have negative mass.

Dear Ray,

"Entropy" and "Information content" are two concepts that emerge over and over in physics, but are not well understood by me and probably many others.

Let's imagine that you and I are playing poker (or whatever your favorite card game is). Let's pretend that you win with a Royal Flush that beats my Full house. So we both throw down our cards. Then, the dealer scoops up all the cards before shuffling them.

From a black hole perspective, I believe that the total number of cards is the entropy that is associated with blachole surface area. The fact that the Royal Flush and Full house have becomes shuffled (loss of pattern) is irrelevant to physicists. A black hole just scoops up more stuff which gives it more possible arrangements (more cards). In other words, when a physicist says that information content is never lost, they mean that "cards" are never lost; however, patterns of cards are completey destroyed and irrecoverably lost forever. If a spaceship falls into a black hole, all of the possible vibrational modes are conserved, but the spaceship is completely destroyed.

This is important because we associate age/average failure rate/senility/disease/death as increases in entropy. The fact that systems fall apart is not an indication of increasing entropy. Yes, of course the pattern is getting wornout (randomized), but that has nothing to do with black hole entropy. Black hole entropy is proportional to surface area, which is determined by the mass of the black hole. In effect, black hole entropy is really just mass (surface area). For biological systems, improvement to the pattern can occur without any regard or consideration of "increasing entropy".

I think I might be confusing black hole entropy (= how many degrees of freedeom), with a disorderly pattern (not the pattern I wanted, but a poor variation of it). Can someone set me straight?

Symmetry breaking does change the entropy of a system, but how? Entropy in standard thermodynamics is dQ = -SdT, for Q the thermal energy. So we write the SdT = d(ST) - TdS, and in this closed setting we then have dS = dQ/T. For dQ = cdT, where c is a heat capacity (at constant pressure) then



So entropy increases with rising temperatures. Symmetry breaking is associated with the lowering of temperature of a system. In particle physics this is lower energy, or what might be thought according to the equipartition theorem E = kT The symmetry of magnetization domain direction in a paramagnetic system is broken as temperature is lowed past the Curie temperature. Another way of looking at this is the density of states defines a volume the system can occupy, call that W. The entropy of a system is then S = k*ln(W). Therefore, as the symmetry of the system is broken the W is reduced and so the entropy is reduced.

So what is going on here? We tend to think of the world as having an increase in entropy. The universe stared out with some very low entropy and that increased with time. After all the second law of thermodynamics is dS/dt >= 0. The above theory with entropy and the argument with symmetry breaking pertains to a system close to equilibrium which heat up their environment and have their temperatures lowered. So there is an environment to consider, and there is the fact this produces a statistical ensemble of possible symmetry breaking outcomes. In the ferromagnetization case there are many domains of magnetization in many directions produced by heating up the environment. Symmetry breaking for first order phase transitions also involves the generation of latent heat, which increases the entropy of the surrounding environment of the system who’s entropy is lowered.

It could also be seen that this is one reason for inflation. The relationship between the inflaton particle and the Higgs field is not completely clear. However, the breaking of a certain symmetry condition effectively dumps “heat” onto the environment. The temperature lowering of gauge fields is accompanied by the expansion of spacetime and the stretching out of the cosmological horizon. Here the temperature is lowered, but with spacetime the effective heat capacity is negative, so lower temperature means higher entropy. This is contrary to most systems in statistical thermodynamics. This is why large cold black holes have greater entropy than small quantum black holes with a hot black body temperature. So when it comes to the entire universe the breaking of symmetry is then involved with a net entropy increase for the universe as a whole.

I hoped I did not give that impression. A biological system is removed from equilibrium, and as such has lower entropy. The death of a biological system means it has approached equilibrium and information about that system is mixed into an ensemble or effectively erased.

You didn't give that impression. I guess I need to really look at thermodynamics. So biological systems are considered to "not be in" equilibrium. On the surface, that seems reasonable. But then what is equilibrium versus non equilibrium? I guess equilibrium is when the energy for all degrees of freedom are averaged out?

Back to neutrinos. Can I assume that the LHC cannot detect them? Yet they will carry away some spin from the reaction. For that matter, can the LHC even detect spin in the absence of electric charge? I guess I should check their website. I am curious as to what the LHC can measure directly, and what they can surmise from indirect evidence. I'm also curious about the "weak force" charge.

Dear Jason,

You are partially correct. The LHC's detectors cannot detect weakly-interacting (via the Weak Nuclear force) particles. Its calorimeters can detect the directions of energy and momemtum deposits. This allows us to reconstruct vectors and determine a neutrino's signature based on missing momentum and missing energy (the missing mass of neutrinos is too negligible to measure accurately). In the case of Neutralinos, these are expected to be massive (~TeV), and its signature would consist of missing momentum, missing energy, AND missing mass.

The "weak force charge" is SU(2)_L weak isospin (which mixes with a U(1)_Y of hypercharge to create mixed quantum states of photons and Z's). I talked about it in my essay and my book. Just don't confuse it with my "Hyperflavor" which is an SO(4,2) left-right-handed symmetric extension of the Weak force.

Have Fun!

Dear Ray,

So if the LHC has a missing momentum/enerrgy, from the calorimeter readings, equivalent to a neutralino, for a reaction that hypothetically might yield a neutralino, they will announce the detection of a neutralino? I guess we should be happy that this is even possible. So how does this influence the prospects for detecting the existence of other dimensions? ...or for that matter, FTL particles?

By the way, I was wondering if you know anybody at NASA/other places, who is working on FTL propulsion and/or exotic propulsion physics? I really need to share my ideas with people who have a similar interest. Eventually, we are going to need some kind of lepto-tachyon, chromotachyon, and the like. This buisiness of tachyons flying off to infinity, or time traveling, is just not an idea I can support. I believe that tachyons have to be some kind of interface between this space-time and a second space-time with a c' > c. I'm looking for people I can blog with who think this idea has merit.

Lawrence B. Crowell wrote on Dec. 3, 2009 @ 22:16 GMT
Neutrinos were first suspected in beta decay because the positron and proton in the decay of a neutron would fly off in directions not opposite to each other. So a missing momentum is a clue to neutrino production. Later the spontaneous creation of pions and leptons from "nowhere," but near a scattering event indicated the presence of the neutrino. Neutrinos only interact by the weak interaction, and so have a small cross section for interaction. They are notoriously hard to "catch."

Neutralinos will appear as something simialr, but with a hefty mass. Then neutralino is also self annihilating, or Majorana, which means their presence will often appear in the production of photons or Z particles.

Dear Jason,

We rely heavily on Monte Carlo event simulators to interrelate experiment and theory. The amount of missing mass will allow them to 'measure' the masses of Neutralinos (if they are produced and observed indirectly).

If the theorists don't build extra dimensions into their models and simulations then they won't even know what to look for, or that they've found evidence for higher dimensions. Realistically, I don't expect to find any direct evidence for higher dimensions at LHC - discovery of SUSY might imply extra dimensions. At NASA, I knew a Larry Smalley (Prof. Emeritus at the University of Alabama in Huntsville) who was interested in using String Theory to find higher-dimensional shortcuts from one point to another. I haven't corresponded with him in a couple of years - he may be in bad health.

Dear Lawrence,

That's very interesting that the proton/electron fly off in different but not opposite directions. I've heard the small cross section interpretation used to explain the lack of detection of gravitons. Cross section is necessary to set up the quantum mechanic scattering problem. But I wonder if it's really a lack of coupling between neutrinos/Higgs/gravitons/etc.

Dear Ray,

Can extra dimensions also be interpreted as zero coupling between particles? I can't visualize 11 dimensions. But I can imagine two or more space-times overlapping where the particles in each do not couple or interact with the particles in the other.

Ray Munroe wrote on Dec. 4, 2009 @ 02:15 GMT
Dear Jason,

Yes - Interaction cross sections are very small for particles that only interact weakly or gravitationally. The LHC is not designed to directly detect neutrinos or gravitons. Super Kamiokande is a good example of a neutrino detector.

I suspect that some forces (such as Hyperflavor and WIMP-Gravity) are very weak because most of their field lines are contained by their respective branes. If Gravity is spread out over 11 dimensions, and electromagnetism is spread out over 4 dimensions, it might help explain why Gravity is so much weaker (field lines spread out over more dimensions).

The coupling between Spacetime and Hyperspace must be very weak (of order G or the inverse of Dirac's Large Number), and thus it should be nearly impossible to discover Hyperspace at the LHC. I still think we need a black hole, but that is Lawrence's specialty.

Dear Ray,

This is still a hard nut to crack. Specifically, how does one couple between our space-time and a faster space-time or hyperspace? I thought about why the speed of light is its value and not some other value. Why can't c be larger? Since c^2 = 1/(permeability * permitivity), one reason that c can't be faster is because it has to create ripples of both electric fields and magnetic fields. If it didn't have to generate electric and magnetic fields, then it could go faster.

By the way, I've heard many times that gravity is weak because it has to spread out over additional dimensions. Since F=ma, then mass directly ties into acceleration (motion). When gravity exerts itself, we say that space or space-time is curved. But when two charges exert a force on each other, we talk about wave function for the potential energy V(r), for a charge. Without using relativity, can we set up a wavefunction for a gravitational potential?

You are effectively askiing whether or not gravity is quanitzed. As yet that has not been done. General relativity up to second order in the post Newtonian expansion appears similar to Maxwell's electrodynamics. That can be quantized in much the same way electrodynamics is. This is a sort of linearized gravity which can be quantized as with any other field theory. The metric is treated as a flat metric with a perturbing metric



and wave equations readily derived. This is how weak gravity waves are modelled. The wave equation is of the form

So the perturbing metric is proportional to the stress-energy tensor (times G/c^4). I figured the Einstein equations would pop back in my lap. But I think I can answer my real question. I do wonder if this perturbing metric, or for matter the Ricci tensor, if either of them have the effect of changing the distance between two points in euclidean space. Perhaps it's not the distance between them that changes, but rather, the potential energy. Is it reasonable to infer that any particle, wave or field that can be compelled to acclerate by gravity, where gravity is just the curvature of space, then these particles, waves and fields must be constituents of space itself? Can we infer that gravity is nothing more than space that has some scalar potential energy?

The * thing in the box should not be there. This is for the momentum-energy tensor T_{ij} = 0 is an elementary wave equation. The solution to this wave equation has elementary Fourier expansions, which are easily converted to quantum wave solutions. The wave equation is similar to that for photons, but where there are two directions of polarization. In quantum optics there are di-photon systems similar to this, and these are a sort of analogue of gravitons.

Of course know about the Casimir effect. It is really like strings on a guitar, which from fret to nut hold a discrete number of wavelengths. The same holds for virtual photons inside the cavity. Yet outside the cavity there is a continuum of frequencies. Hence the vacuum energy in and out of the confined region are different. This results in the measured pressure on the walls of the cavity, or parallel plates.

One must remember there are the phase and group velocities of a wave. The phase velocity is that of the wave fronts, which is where information is communicate. The velocity is v_p = c/n for n the index of refraction. There is also the group velocity v_g = c/n_g, where n_g is the group index of refraction

n_g = n + ω(∂n/∂ω),

where there is a frequency dependency on the index of refraction. For ω(∂n/∂ω) < 0 the group velocity is faster than light. Yet no information is communicated here, for this velocity corresponds to the velocity of Fourier components of a wave, not the entire wave which communicates information. The term ω(∂n/∂ω) in the case of the Casimir effect is one where it is less than 0. This can be seen since n is for all Fourier modes of EM radiation and the dispersion term removes the contribution of frequencies on n in the trivial case n = n(ω) = constant. So the velocity which changes is the group velocity, not the phase velocity. As such there is no communication of information faster than light.

This is basic refraction, of which Snell's law is an example of. In general a media can have an index of refraction which depends on position in space and frequency of light. Chromatic aberrations are an example of a frequency dependency on the index. This occurs when a lens induces different paths fpr different colors of light.

Dear James,

I think that the physics community has an air tight representation of the laws of physics. Whether or not it's complete in the exotic sense (FTL/many dimensions), I cannot say. I can certainly point out all of the possible hiding places. If a tree falls in hyperspace, but the physics community has no proof of hyperspace, did the tree really fall? It's not much of an argument, but I can't reveal FTL propulsion without evidence. I do know that photons are quantum wavefronts of undulating electric and magnetic fields; that's just the poyting vector. Are the Higgs field, permeability, and permittivity all manifestations of the space-time brane? If I propose a second space-time with a different speed of light, c'>c, different kind of charge, but I keep all of the geometry the same for simplicity, then perhaps I can propose a way to acheive FTL propulsion. But if I have no way to interface the two space-times, if the two space-times have nothing in common, then a second space-time is really unhelpful towards an FTL propulsion objective. They say that all things that have both mass/energy content as well as information content, all of those things are allowed to contribute to the force of gravity. In fact information content via entropy are the last outpose of this universe. If you leave this universe through a black hole, you must give up your energy content and your information before passing through the event horizon; beyond which there is either maximum packing of quantum matter, or there is a tumultous storm of extreme energy that buffets against the speed of light barrier. At the smallest scale, the quantum wave function appears; it is the other unknown. Particles can be in multiple eigenstates simultaneously; but the math doesn's tell us more than that. These are the two doorways into this physical universe. The quantum wave comes from the potential energy of the charge; the black hole comes from mass-energy density. The light spans both of these horizons, but cannot reveal what lies beyond in the darkness.

I agree too about this constant and our limits .It is the reason why I like read the extrapolations of Jason and his super creativity .I think he is going to find many relevances in this road .The constant and our limits are bizares in an interactions optic with the universe and its bodies in rotation .Sure it exists some roads to check the space and thus the velocity and the movement .Perhaps we are youngs and thus it is ht reason why we can't travel behind our system .Perhaps it is well like that ,indeed the planets I think are not there to sell their elements .Perhaps the step by step is essential and that to respect this universe and thus utilise the discovery in a pragmatic road of harmony .

I am very intrigued about the check of this space and our dimensions so far of us .Sure it exists some roads of improvement of the motion .Sometimes I say me ,if the contraction is a reality thus a decrease of the space is logic and rational ,furthermore if all turns around the universal center thus even the topology must be adapted with the evolution since the begining of the big polarisation if I can say .

The astrobiology is an evidence and many biological systems are everywhere ,thus how can we arrive to interact ......the evolution seems the main part of the puzzle ,even the consciousness seems on this road .

Perhaps the velocity is the key ,perhaps the contraction and rotation,perhaps the evolution is the key ,perhaps the intrinsic codes of the elementaries particles,perhaps some doors where all is light thus the code is important to re polarise,perhaps it is the propulsion .....probably what the rotating encoded system is important ,thus what is the cause thus how can we teleport in a light continuum with a spherical system in a other place in this universal sphere .That becomes very complex the cause of the rotation thus the mass .If we want to re polarise or re create a mass thus we must check the cause of the rotations and its superimposings since the begining .That seems not possible at this moment this super motion .It is the same with the light ,a rotation exists too thus if we want to be in this continuum before the re creation ,we must check there the sense of rotation and its velocity ,which is peobably the maximum gauge furthermore .

In conclusion I beleive what the evolution and its conscioussnes correlated with the technology shall permit these motions in our limited system .

Dear Jason,

"I think that the physics community has an air tight representation of the laws of physics."

I think that this could be said about experimental physics; however, for me, theoretical physics has made many educated guesses since the beginning of theory. These guesses cannot be shown to be correct. They are assumed to be correct. They take the form of imagined properties resulting from interpretations of unknown qualities that appear in the empirical form of the equations that model the patterns observed in empirical evidence.

We do not know the nature of cause. We can be certain only that there is a cause. We are not justified in accepting more than one cause. True unity requires that there be only one primary cause. All effects, including our intelligence and free will, must be the result of different aspects of this single cause. I think that the quote above is incorrect. I think that theoretical physics has created an illusory universe. Einstein pushed for support of his imaginary universe with words to the effect that: "We need a new way of thinking". His willingness to plunge us into accepting illusions has led to modern theoretical physics.

Misinterpretations starting with f=ma, grossly extended by Einstein, and carried on without restraint to this day have put us in a situtation where misinterpretation has introducted distortion into theory. The result of admitting multiple distortions is that solutions must contain multiple contortions. Several of the properties that you mention above are representative of contortions. We are are now required to reach outside of our understanding of this practical universe and imagine the existance of an impractical universe or universes.

It is probably not helpful for me to try to be specific in my objections. You are in good company with Drs. Munroe and Crowell. My opinions would not serve your purposes. I will carry on with my own work and encourage you to do the same. Thank you for your message.

Dear James,

I enjoy reading new approaches to old problems. It seems that good theories may get modified, but never get thrown out completely. Perhaps we should be careful about taking our theories so seriously that we integrate them too much into our philosophy and perceptions.

Jason has challenged me to think about ideas such as hyperdrive more than I would have on my own. I think that constants such as c and h must be Universal within our 3+1 brane of Spacetime. If two different branes had two different values of h and c and classical couplings of order 1, then they should merge and 'average out' the values of h and c.

This leads me to consider multiple possibilities: 1) if a hyperspace brane has a different value of c or h than spacetime, then it can only be connected via a quantum (not continuous) event, and 2) the coupling between our spacetime brane and any hyperspace branes must be very weak - of order G or 10-40 - or else we should have discovered these hyperspace branes.

My education has led to some biases, but I agree that some changes are required in Modern Physics.

Dear Ray,

"It seems that good theories may get modified, but never get thrown out completely."

All good theories are interpretations placed upon the perceived qualities that appear in the empirical form of the equations that accurately model the patterns observed in empirical evidence. The interpretations may consist of real or unreal theoretical properties. The viewpoint of the theorist does not noticably harm the practical usefulness of the equations. When additionally discovered patterns in empirical evidence are observed to require the alteration of the equations, the old theory does not become irrelevant or wrong. It already was either right or wrong.

The potential problem for any new interpretations that are added onto the improved equations is that they are usually molded to successfully reduce, under the older restricted conditions, to the old theory. They are usually considered to represent improvements or extensions of the old theory. Therefore, the uncertainty of educated guesses or just plain wrong interpretations continue to force themselves onto the empirical equations and have a good chance of requiring the new additions to the theory to be distorted. The old theory becomes a special case of the new improved theory. Some error has been corrected, but there may be much more important errors that are retained.

The correctness of modern theoretical physics is very much dependent upon the correctness of older theory. I think it is important to recognize that the older theoretical interpretations of perceived properties have not been proven. I think it would be wise for modern theoretical physicists, with their vastly improved knowledge, to return to the fundamentals stripped bare of prior theoretical bias and make modern educated guesses. For me the key to correcting such theory is to include unity right from the beginning. For others there may be a different path. I do not think that we are currently on the correct path.

The hyperdrive is the dream of science fiction. It stemmed early on in part from a cracker barrel idea of general relativity, time dilation, curved space and so forth, and a need on the part of writers and authors to avoid the difficulties of time and relativity. Yet the idea has always presented us with troubles, and these things connect up with time travel, which is even more difficult to uphold.

We humans are amazingly good at using up our environment. Any constraint upon us we eventually figure a way around, and we use more and more of the world. It may have started with Australopithecus when they took themselves off the menu (throwing rocks at that menacing leopard) and put more on their menu. We have consistently supercharged things, eventually with agriculture and much more recently with science and technology we can use things up at a breakneck speed. Take note of this the next time you throw out the garbage. The sense we have had is that the future will hold much more of what we have, remember the cartoon “The Jetsons?” The problem is that in the last few decades things have not exactly worked out that way. We don’t have the Clavius lunar colony seen in 2001 A Space Odyssey, we don’t drive flying saucers to work, we don’t have jetpacks and so forth. We are also facing a host of growing problems due to our exploitation of the world. Physics is pretty much giving us obstructions on futuristic ideas like warp drives, and astronauts on Mars is as far off in the future as it was in the 1970s. In fact it could be said that in recent time our world is largely about hi-tech farting around --- web game sites, nonsense blogs, web conspiracy threads etc. Oh, and yes, there are the wars. We might in the end be just played a grand Ponzi game, a pyramid scheme based on energy and resources, and we might be reaching the limits on that --- endgame.

So things have not worked out exactly right. Even if we do manage to get a reasonable theory of cosmology and quantum gravity, chances are we will at best get tangential evidence to support it. So as Sting of the rock band “The Police” put it make the best of what is still around. Maybe we are just a way the universe becomes aware of itself up to some limit and then goes back to sleep.

So with our engineered planetary mass extinction, and collapse or implosion of the human condition, there might for the next 100,000 years or more only be a few hundred thousand Homo sapiens in isolated population pockets around the planet.

Front-load washing machines use less electricity, less water, and less detergent than the average top-load washer, so consumers can continue to consume, but reduce their carbon footprint at the same time. Most people I know consider a washer and a refrigerator necessities, not luxuries.

We haven't fully tapped a variety of resources because they are more costly (solar and wind) or dirtier (coal and nuclear). As we consume our fossil fuels, we must make the tougher cost vs. benefit decisions of the other resources. I once studied Plasma Physics because I thought Nuclear Fusion was the future of our energy requirements: heavy hydrogen is abundant, and fusion is generally cleaner than fission. However, it is difficult to achieve, and became obvious that only the larger cities could afford the multi-billion dollar tokamaks. If we ever surpass the break-even point in fusion, then these larger cities could sell hydrogen gas to the smaller cities. We could have cars and smaller power plants that burn hydrogen and produce water steam. Yes - water is a greenhouse gas, but water is the cleanest waste I can think of.

Have Fun!

Hi all ,

Dear James ,

I agree totaly with you .It is what I said too on the blog of Mr Oldershaw,the old school is the base .The superimposings at this moment becomes confusing .

You speak about an important piece of the puzzle,the referential and its uniqueness ,its laws ,invariants and constants .The base is the base.Einstin was the chief of the distorsions of equations .Like an utilisation of our imagination with the infinity .That implies of course the confusion if the evolution is considered .The personality I think is unique and thus the creativity too ,but I beleive strongly what the referential is essential even with the imaginaries ,the sisters of the EPR and the others paradoxs .The balance between the rationality and the unlimited creativity thus is young ,that implies an understood confusion .The uniqueness of a system ,created thus will be always inside the specific system where the imaginaries and the rationality at the unification becomes pefecty synchronized ,of course at this step of perception and understanding ,even the difference between them doesn't exist at this scale of evolution and harmonisation .This line of reasoning implies thus possible synchronizations between all imaginaries extraplations if and only if the universal referential is taken in its specificity ,where the zero ,the - and the infinity are analyzed with pragmatism with the pure physicality .

The reasonability thus becomes the sister of all our imaginary extrapolations .

With this perception ,the illusion of course is not a reality .

I liked a lot your words dear James ,

" For me the key to correcting such theory is to include unity right from the beginning." the referential always and thus its limits .....

Best Regards

Steve

Dear Ray,

I keep hearing reports that CO2 levels rise after global temperatures rise, thus destroying the causal relationship between CO2 and global warming. I also keep hearing reports that we are in a global cooling period, not a global warming period. Furthermore, I am also hearing reports that climate change scientists are fudging their numbers because, like everyone else, they like getting paid, too.

My girlfriend keeps asking what I want for Christmas. I don't really need anything. Of course, I have lots of student loans and a car payment. I'm not a great aggregator of financial wealth. If we're in for a depression, then prosperity is just not in the cards.

The truth is that I'm not really interested in stuff; I like ideas and I am developing a fondness for human(e) topics, experiences, and things that require a soul. I'm not some souless hominid in a dying universe, waiting for the next iceage or Hitler to come along. Let's just face it; science has nothing to contribute to the important parts of life. First, the physics communty came for our religious convictons and they watered it down and undermined it. They murdered our God and told us we had no soul; that made it easier for the Nazis to kill millions. Or if you prefer someone more contemorary, a Sadam Hussein. He gave his two sons, republican guard and henchmen, a license to torture, rape and kill millions. After all, they were just hominids; they had no soul and no God; in fact, the universe is dying of heat death, so who really cares.

I'll describe my next attack on the speed of light when I'm not so pissed off.

Dear Jason,

Don't let situations you can't control rule your emotions. Just do your best and be your best.

"Finally, brethren, whatever is true, whatever is honorable, whatever is right, whatever is pure, whatever is lovely, whatever is of good repute, if there is any excellence and if anything worthy of praise, dwell on these things."

My wife asks me what I want for Christmas. I usually say "Peace on Earth" knowing that she and I can't make that happen by ourselves (and withdrawl from a war that leaves socio-economic chaos behind is not true peace), and knowing that she'll probably get me more clothes instead.

Climate is a tricky subject. It requires decades - and maybe centuries - of data to understand. It seems that our average temperature has risen slightly in the past century. If we project this out exponentially with the economic expansion of our most populous regions (such as China and India), then this could be a bad omen. On the Gulf Coast, we worry about Hurricane seasons becoming worse with time due to warmer waters. Only time will tell... I just hope I don't have to move to the hills of northern Georgia to find beach-front property.

Have Fun!

Dear Ray,

It's not that I'm ruled by my emotions. I'm very tired of having to be a good little "scholar" who never gets mad or feels any passion. If I don't throw a fit now and again, it's like my emotions are dead. I don't want to be a "Vulcan", all logic and no passion. I want my passions to enrich people's lives; to inspire others to dig deep into their feelings. All this thermodynamics business is about systems in equilibrium, dead things. Biology and emotions could be a sign that nature doesn't like equilibrium. Maybe the laws of physics and/or the physics constants can be seen as equilibriums. In other words, how do we know that the equations of physics are not just iterative relationships. What if there are iterative relationships that enforce the physics constants. c = f(G,h); speed of light is an iterative function of Planck and gravitational constant. Planck cosntant h = f(c,time it takes for nature to establish enough resolution). And G = f(c, geometry). Three iterative relationships. My examples are just to get the conversation started. If there were three primary equations that iteratively arrive at the physics constants, then it might be possible to upset this equilibrium approaching iteration. In doing that, it might be possible to tamper with the constants themselves. But then: What are those three primary equilibrium equations?

I transitioned from a social/humanities topic to a possible way the laws of physics might be implemented. Was it too drastic a transition?

One of my talking points was that physics/engineering/chemistry/etc all rely that the system will approach an equilibrium. But "equilibrium" seems to imply "dead". There are lots of living systems that are not in equilibrium, animal life/biosphere/economony/emotions/etc... Systems that are not in equilbrium are probably too difficult to model or predict.

This thread has gone a bit off any physics track. I think this recession is a bit more than a siimple economic downturn. I think this is the beginning of American decline as a world power. It is very clear that China will be running the world by the mid-21st century, with Europe and India assuming sort of second place positions. The United States is a classic case of a declining power, which I suspect is evolving into a neo-third world nation state.

The world is still mad at us because we removed a tyrant from power; do you want him back? I'm not sure I know what China has that will give it the edge in the middle to late 21st century; perhaps motivation? Sure their economy is growing; they are a major user of oil now. Perhaps they will swallow up an oil country at some point in the future; Russia, I doubt it. China swallowing Iran might be a future headline. I doubt the Chinese will be too concerned about protecting the world oil supply. They would suck it dry, which is what the US gets falsely accused of.

Dear Dr. Crowell,

Ok so, as a physicist, you feel educated enough to make grand pronouncements about God and religion, and, now our political future. I would encourage you to first straighten out theoretical physics so that we no longer have wild theoretical speculation, but rather, practical empirically substantiated knowledge.

The United States of America will decline if we relinquish our foundational principles. The most important of these is to offer liberty to ourselves and others and, when severe difficulties arise, as in the American confrontation between slavery and freedom, to offer a rebirth of liberty to ourselves and others. Liberty is more important than individual survival.

Liberty is based upon the highest level of political intelligence achieved thus far. It is not the fruit of socialism or communism. It is the fruit of American style, as in the Bill of Rights, restricted individualism. The restriction seeks a balance between individual rights and the liberty of all. It is more valuable than economic security. Liberty requires us to remain vulnerable. It is worth the risks. Times may be good or they may be bad, but, liberty must survive.

If the world is going to have a chance to survive humanitarian crisis, or economical crisis, or environmental crisis, it is the United Sates of America that has the best attitude and means to help ourselves and the world to avoid these climaxes.

So much of the current academic attitude presents a grossly distorted universe, a grossly distorted idea of government, a grossly distorted idea of economics, a grossly distorted idea of morality, and a grossly distorted idea of the United States of America.

I do not know yet if this description applies to you or not. However, if fqxi should decide to start a thread on the character and future of America, I will participate.

As an American, let me tell you why America will remain a dominant and influential nation for the next thousand years. You see, intellectual prowess and genius are useful in the short term; but from an evolutionary perspective, they are completely useless. The new hominids who will have amazing survival skills; they will come from places like the Jerry Springer Show and also anyone who makes a movie called Jackass. For some reason, evolution favors the dumbest and most obnoxious kinds of people. These same dumb and obnoxious people will continue to join the Armed Forces and run for elective office. For the next thousand years, the United States will occasionally get the itch to go to war; a Republican will get elected as president, a war will start, and a tyrant will be devoured. The world will always hate us and falsely accuse us of being an empire. For some strange reason, freedom will continue to spread.

For the strangest reason, these new hominids will not be able to say words like "extinction", "environment", or "hominid". They will believe in God, read horoscopes, and outlast the smart people by 500,000 years.

Dear FQXi Friends,

Where did the hyperdrive blog go?

I like James' perspective.

I'm not a pessimist, I'm a realist. Don't trust the government too far - they are nearly bankrupt themselves, special interest groups will get their piece of pie before any of the rest of us, and their fiat money is only as good as their ability to back it. I don't think that one President (or one political party) can get us out of this mess - regardless of how good a speaker he is. We are in a cyclical finacial crisis, and it may take two or three 'scapegoat' Presidents to slowly lead us out (unless we use a major war like FDR did with WWII). Don't trust large corporations too far - they are nearly bankrupt, and will pay their CEO's huge bonuses for mediocre performance before their shareholders see a penney. Don't trust the stock market too far - it may be a huge Ponzi scheme, and the brokers are higher up the pyramid than we are. Silver bullion is still affordable, but you can't eat it for breakfast. Our FQXi friend, Owen Cunningham got laid off a couple of days ago.

At the end of the day, all you can really count on is yourself, your intelligence, your strength, and your available resources (invest those wisely!). The future of America depends on the next generation. If they maintain their freedom and dignity, then individuals (like Jason or James) can invest everything they own into marketable ideas. Liberty and small business was the foundation of this country's wealth. Just imagine how wealthy Jason could be if he patented and marketed the first hyperdrive vehicle! I could say I knew you before you became a Billionaire.

Hi all ,

Dear James ,thanks .

To all ,

The last threads have a politico economico realism .....I insist on one fact important ,the humans are humans and it doesn' t exist differences between them .If the actual situation and the crisis is not taken universaly ,the problems shall be more important like a ultiplication and acceleraton of the chaotic systems .If the Earth continue to consider differences ,thus the checking will be a parameter of the local prosperity .

Whe you say Lawrence about USA and Chine ......I don't agree because the essential parameter is not inserted ,the universalism and its aim ,simply ,thus we are humans and that is all .I repeat and I think it a real important reality of our Universe in evolution .

Some human inventions are dedicated to disapear in Time and Space evolution ,fortunaly (weapons,borders, differences ,monney ,....)If a real universal community govern this planet ,all will be different and towards this harmony .The problem is not the universal laws ,but the young age of humans ,we are babies and we make errors ,but we evolve and thus we can improve ,optimize and harmonize.Of course now it is just a question of time and locality ....but I beleive strongly what the real solutions exist and are applicables furthermore by this simple fact the adapted harmonious sciences .

If we rest with our bad habits ,we shall add chaos ,on the other side if we apply the universalism ,it will be easier for all humans without differences .An american is an human ,a chinois is a human ,a musulman is a human ,a christian is a human ,a bouddhist is a human ,a black ,a white ,a blue ,a green ,....a rainbow this humanity ,a diversity of colors unified in this light ......we are youngs ,very youngs at the universal scale ,thus let' s improve the universality .

For the climat and the energy and the food ,simply the soils ,on air and in oceans ,it is the key of the balance on Earth ,a real harmony between animals and vegetals .Thus let's improve these soils .A global commission of the soil must be implanted on Earth ,it is essential .The argilo humic complex ,which I work since several years is the key with some adds by powders to dynamize the bio chem system and its interactions .With a good soil ,the rest is evidently more simple in the bio diversity of the global ecosystem .

The solutions exist .The problems too exist .....universalism or earth actual system ,to be or not to be .....

Take care humans and let' s improve the universalism the uited is a key too ,the ideas of 10 are better than the ideas of 1.All is there the complemenatrity towards the harmonisation ,the perfect sphere for me and its spheres.

Jason,

because you asked. (According to the model I have been proposing.)

Energy is change in quaternion spatial position. It can be identified as kinetic energy within 3D vector space or promotional energy along the 4th spatio-energetic dimension.

All matter and particles possess both forms of energy because change of spatial position is occurring both within 3D vector space and along the 4th spatio-energetic dimension. Potential energy is the potential to cause change in quaternion spatial position.

A small change in spatial position can lead to a subsequent larger change via the processes of chaos and complexity occurring within quaternion energy-space.

Change in position is conserved (and thus energy is also conserved) in that every change in position causes a further change in position of matter, particle or medium. There is thus ceaseless perpetual motion within the quaternion Mega-universe.

Therefore terminal entropy is not the inevitable fate of the universe. IMO.

Georgina Parry wrote on Dec. 9, 2009 @ 19:54 GMT
With regard to my previous post,

when discussing entropy, argument based on the expansion of the universe does not apply to the model I propose. There can not be such expansion IMO as it does not permit explanation of gravity, that -is- possible with contraction along the 4th spatio-energetic dimension.

It must be an "illusion" due to motion away from the origin of the EM observed, along the 4th spatio energetic dimension, which will be away from the origin of the EM of all of the stars. This could hypothetically give rise to the red rift which may be incorrectly interpreted as all of the stars moving away from the earth or telescope through 3D vector space. Movement away along the 4th spatio energetic dimension will also give spatial rotation.

Current universal expansion theory relies upon insertion of a cosmological constant to fit the observations, interpreted as expansion, with the scientific and mathematical framework. It is a "fix". There is not therefore theoretical verification of the supposition of expansion.

The one thing which marks our current age is the rapidity of events. The rate things change is exponentially increasing, and this has some resonance in history as well. If you want to look at civilizations which lasted (well nearly) a thousand years it is best to look at the Old Kingdom of Egypt. If you heap the new Kingdom and the Hyksos period between them Egypt worked out for nearly 2000 years. Long lasting Empires after then had a shorter duration, such as Rome. We can forwards to the Ottoman Empire, Spain, Britain and so forth and you might notice that the time frame for each of these is generally shorter. Now it is America's turn, and I expect the exponential contraction of time frames to have much the same result. If China takes the world center stage they might hold it for an even shorter time period. We live in an age of increasing impermanence.

As for America, this nation was founded on some good ideas which came out of the enlightenment. I don't want to go into depth on this, but there are some rather negative elements to our civilization. A lot of what we learned about the American Revolution is sort of silly. The real reason for the revolution was to grab land held by the Cherokee and Chocktaw nations, which formed buffer regions between the British and French Americas. This was negotiated in the end of the 7 Year War, called the French and Indian War here. It took Andrew Jackson to clear the natives out. The American Revolution was a complete disaster for native people here. I could write much more on this, but... time and space are limited.

I will say that a civilization is entering its greatest depths of trouble once its people begin to see themselves as having some mandate of righteousness or some invulnerability.

Dear Dr. Crowell,

Everyone and every discipline and every nation and every religion and every whatever has negative elements. This nation was founded on Great Principles such as self-government. Self-government is not silly. What is silly is thinking that the merit and worth of this country depends upon evaluating those things that really were or 'now appear to us' to be wrong, from today's perspective, with what American's did 100 and 200 or more years ago. What do you know about the difficulties and great challenges they faced? What would you have done then? What makes us worse and less deserving of success than other civilizations such as Stalinist Russia or Communist China?

Are numbers of people more important than quality of principles? Is liberty not worth the struggle of human endeavor? Is that your point? What is so perfect now, either in America or the rest, of any other part of the world, that has anything at all to do with risking losing liberty? Regardless of whatever else is happenning, because of politicians or university professors, the most important quality that American's, as a whole, have to offer to the world is liberty!

The last thing we, or the world, needs are panels of experts, or even worse a single panel, or even worse a single person of specialized but limited, this includes physicists, education deciding, or even worse 'declaring', how the rest of us must live our lives in order to be responsible and moral and right!

It seems to me that it is popular for intellectuals to declare previous generations as being innocent, immature, and underdeveloped and, lacking moral clarity. Now, I will say declaratively that: This generation knows very little about facing real challenges, and knows very little about real sacrifice and still to this day knows very little about the reason for existence, whether through physics or any other of our compartmentalized scientific endeavors.

Everyone is limited in their knowledge and correctness. That includes us today. Now would you please, until moderaters end this, please explain why America is worse compared to either others in history or today to the rest of the world?

It's funny you should mention righteousness and invulnerability; maybe we learned to do both 'better' then the empires of ages past. If American goes away and China becomes the world's superpower, do you think your freedoms will be any safer? I understand that freedom is difficult to deal with.

Dear Lawrence,

I've been overseas, to Germany when I was a young pup; and to Kuwait when I served in the US Army; I served during peace time. If the United States has supported or installed dictators such as Sadam Hussein/others, then that presidency was wrong to do it; whether or not it was a lesser of two evils decision, I cannot say. I am told that the US helped Sadam hussein get into power so that Iraq and Iran could slug it out for a while. If that is so, then we should have removed Sadam from power during the first gulf war. We Americans complain about our government; but the truth is, we have it so good here in the US. We have a lot of freedom, some health care, and a government that is trying to figure out how to best serve its people. In foreign lands, I seriously doubt that those governments give a damn about their citizens. If Kuwait, South Korea, present day Iraq, seem worse to those who wait for America to decline, let me tell you something. North Koreans are starving; I've seen video where a man was so hungry, he started munching on cow poop. South Koreans have had the US in their country for 60 years; they eat well and enjoy various freedoms. Before Sadam Hussein was removed from power, he was torturing people; not water torture or barking dogs (which was wrong), more like body shredders and rectally inserted coke bottles. There are still problems in Iraq/Kuwait, but the torture faciliities have been destroyed.

The Constitution of the United States has been a powerful document towards the cause of human and civil rights. Those human and civil rights have emerged in nations where the US intervened. I am pretty sure that the Chinese government, whom you are rooting for, would wipe their back side with our civil rights legislation. I'm sure the Tibetans would agree. But feel free to blame the United States if that makes you feel better. But don't look to the Chinese to improve anyones quality of life.

Freedom of thought and speech are also important freedoms.

Learning sometimes involves changing ones former beliefs. Polite and reasoned debate with others allows current opinions to be modified in the light of additional information or a new perspective. I find that much that I used to believe, including much "received wisdom" and teaching is untrue but that does not mean that I was formerly ignorant or at fault. My former opinions were valid given the information I had available. I am still learning. To suppress thought and speech or to verbally attack another person because we dislike particular ideas, viewpoints or their expression is to hamper or prevent the free exchange of ideas and the opportunity to learn from each other.

Dear Lawrence,

This is a response to comments left on "The Art of Combining..." blog site.

I have a trace of Minorcan in me. My Minorcan ancestors came to New Smyrna, Florida as endentured servants as part of Dr. Andrew Turnbull's British colonial experiment in the late 1700's. The slave ship from Africa shipwrecked and all were presumed dead, so the endentured Mediteranean peoples of Dr. Turnbull's colony effectively became the slaves. They endured hardships, disease and death until they finally marched to St. Augustine and asked the Governor of East Florida for freedom.

My wife is part Cherokee. They were forced off of their lands (recognized by British treaty) by the State of Georgia and the Federal Government because of the Georgia Gold Rush.

I live in the South. I have seen the dangers of racism.

I know that America isn't perfect. The Constitution gave rights to white, male, landowners, but was designed to be changed - to adapt with the generations, and thankfully it has.

Freedom of thought and freedom to pursue our individual dreams is important. It was those freedoms that helped America become the Superpower that we are today.

Every generation has a choice to be great, or to fade away into history.

Our current national debt is about $40,000 for every man, woman, and child in America. How far will our Debtors allow us to extend our credit? $50,000 or $100,000 per person? At some point, they will ask for a substantial payment or collateral. What happens when the Federal Government asks a large state like Texas or California for a trillion dollars, and the state says "No, you spent that money on Special Interests, not on our State"? If one state splits from the Union, we could imagine a chain reaction whereby the South, Midwest and Northeast also become independent countries, and the "US" becomes at least 5 different nations split along historical, regional, cultural, and/or racial lines. The USSR faced a financial crisis (may I emphasize that financial crises are cyclical and 'normal', but to Lawrence's point they may grow exponentially more extreme) and split into 15 different nations.

That is one scenario whereby America could collapse. Another is if we give away our freedom in exchange for 'phantom' security. I say 'phantom' security because you never have real security without real freedom. In the past 100 years, more people have been killed by their own governments than have been killed in wars.

America isn't perfect, but I'm not perfect, and I don't know any perfect people either.

Can we get back to hyperdrives? I want to see Jason make his first billion dollars.

The things around us are the same for all ,only the human point of vue can be chaotic.

The reason is to be universal ,the rest is not important .The evolution and the improvement of course are a real hope to decrease the stupidity.

If you give a game to a young people ,his age is 6 years ,and if on the box ,we see ,interdfiction under 12 years ,thus you can correlate this fact with our actual tools .Don't give tools to a unconscious people thus .It is only simple like that .

If the differences are made ,it is impossible and of course don't confound the specificity and the uniqueness with the individualism ,there a balance too is necessary .The human is a simple catalyzer of the physicality in evolution and optimization .Our story is just a step and our errors too ,the time is more important than just our age .

It exist ionly one tribe ,the humanity and its aim .The universe is not a play ,just a foundamental evolution towards the perfect harmony between mass systems ,spheres and their lifes and creations ,these polarisations of complementarity .All is complementary ,all .

The future is a harmony .

What is our rule of humans ,simply catalyzers of the truth .The sufferings thus in this line of ectrapolation will disapear like the stupids imaginaries inventians implying chaos .The present becomes thus a time of responsability where the past is analyzed ,studied to improve and evitate the errors and that to be in the synchronization of the universe and its aim .The polarisations aren't there for nothing ,all has a rule of complementarity if and only if the foundamentals are inserted with pragmatism .We can't fortunaly change this universality and it is well like that .The future =hope thus .......

While Lawrence was deriding gods, rituals and traditions, one of the chains that bars the darkness, the evil within every human, was allowed to escape, for it felt no fear of eternal retribution. As humanity continues to withdraw from the Creator, more darkness will come forth. Perhaps it is better to let the faithful do what they are intended to do.

It is better to let those of different faiths find some common ground, then it is to deny the Creator's existeence.

Well above I argue pretty much that warp drives will not happen. To be honest I think they are physically impossible. They are similar to perpetual motion machines or time travel. I mentioned how our view of the future has changed, and so forth. What I am saying largely is that we are in a whole lot of trouble, and the future seems to be taking us further away from science fiction ideas --- except for maybe Soylent Green.

As a proponent of the warp drive, the biggest obstacle I see is that we do not have clarity on how the space/space-time architecture is constructed. We just don't know how the laws of physics are implemented. It could be an E8 or some kind of space-time crystal lattice; it could just as easily be some kind of amorphous aether-like brane. Whatever implements space-time, we have to take a piece of it, the piece with the hyperdrive starship inside, surround it with some kind of warp field, and transmit equal/opposite momentum from the spaceship, through the warp field, into some kind of hyperspace. For right now, we'll just have to wait for more physical evidence. By the way, the dark matter that we discussed a couple of pages ago, is probably significant. There seem to be invisible yet gravitationally significant objects in space, called dark matter. Whatever dark matter is, it doesn't seem to acknowledge light, because light passes right through it. Perhaps these are regions of space where the permitivity and permeability are zero? Just a thought.

As I indicated the group velocity of a wave can change so it is greater than the speed of light. The general problem with warp drives or any system which is proposed to travel between points x and y at a speed faster than light is that one can easily transform coordinates of observation so that you travel from y to x. It would also be possible to transform the opening points x and y, if these lead wormholes or some other spacetime where its purported speed of light is c' >> c in our spacetime, so that you get time travel or closed timelike curves.

I suppose this is in part why things got a bit on the un optimistic side, for the future we see today is not at all working out to be the future seen in the past.

The connection between space and time via the speed of light is nothing more than the propagation of electromagnetic fields to connect charges. In other words, electric and magnetic fields connect electric charges. At velocities v > c, charges between the two inertial frames can no longer interact. FTL is potentially a cloaking technology, as well. Space-time is not a movie reel that you can rewind. If you find a way to travel FTL, you lose the ability to interact with the physical universe. The problem with FTL is that it constitutes a separate space-time that doesn't easily project into our space-time. What is the difference between an object in another dimension versus an object in our 3D space that cannot interact via electromagnetic forces? If charge interactibility can be considered sufficient to represent regions within a dimension, then velocity of charge interaction would lead to a second space-time. So why don't charges from two different space-times interact? Why do charges interact at all? If we knew that, we would know why charges of different space-times don't interact. With that information, we could look at the conditions necessary to make two space-times interface with each other.

The speed of light is really a conversion factor between time and space. It happens to define the paths which massless particle travel on, such as photons. Anything travelling along a spacelike interval (FTL) can interact with the rest of the universe. By the simple fact you travel from x to y and carry information you communicate is an example of interacting with the exterior universe.

Dear Lawrence,

I think we take the words "information" and "information content" for granted. To say that information can only travel at the speed of light is true, subject to the absence of evidence of a second space-time. We really don't know what space/space-time is made of; so we can't really confirm or eliminate the possibility that a second space-time exists. If a second space-time actually did exist, I could potentially transduce particles or signals to the FTL space-time, then transduce them back into this space-time. No time travel results.

If you had two spacetimes that are connected by some bridge, similar to a wormhole (in fact it is a wormhole), then you could in principle boost that opening so as to make a time machine. The connecting region between the two spacetimes is essentially a wormhole, and this can be looked at in some more extensive length than I can write about as the wikipedia site on wormholes.

General faster than light ideas can be found here as well. In effect any faster than light travel can by various means be transformed into travel through time by general relativity.

Arguing this is becoming somewhat fruitless, as you keep wanting to wordsmith things in ways so as to shave down a point. These things have been pretty extensively studied, and they all lead to various uncomfortable conclusions. The configurations are unstable. Such as crossing a wormhole bridge or what might be called a stargate into another region so as to return to our spacetime at some other point. This is a multiply connected topology, which can only exist for certain vacuum configurations where T^{00} < 0, such as a Boulware vacuum across an event horizon. This can potentially happen for near Planck scale physics where the Heisenberg uncertainty principle will permit a ΔT^{00} < 0, so there is a quantum virtual wormhole. Yet this is a nonlocal connection which can’t communicate information.

One reason why earlier I got into the thread on how the future is not shaping up as we once thought is to illustrate how one really should not pursue physics with some idea of a purpose or future prospect. It is best in my opinion to remain neutral on that matter. This is one reason I am not a partisan of the strong anthropic cosmological principle. For all we know our future path might in fact be some spectacular planet-wide train wreck, or where we fade out into the dark as the last financial investment scheme which profits for a time is Soylent Green. We are observers in the universe, but for all we know we might just be some sort of highly improbable fluke. Though in a spatial universe that is infinite anything which is not forbidden or impossible is in a sense mandatory.

I am also starting to think that arguing about FTL propulsion is fruitless. You keep using the wormhole/time machine argument. I keep running into the dilemma that nobody, including either of us, really knows how space-time is implemented or what it's made out of. The other problem is that neither FTL propulsion nor wormholes have ever been observed; so we're both arguing from positions of deep speculation. However, we are both trying to argue from logical and carefully considered points of view.

If you want to exclude the existence from wormholes, that's fine with me. I'm not arguing for wormholes, stargates, time machines or perpetual motion machines. For FTL propulsion to be possible, a second space-time has to exist. This is where it starts getting hard to understand. I have to temporarily manipulate the relationship between two space-times in order to get a bubble of standard space-time, with the spaceship inside of it, to exist in the FTL spacetime/hyperspace. The metaphor would be a bubble of air under the water. The issue becomes, can I get the bubble in the first place? You will argue that a bubble leads to a waterspout which is basically a worm hole. I will argue that if you try to do this, the waterspout (wormhole) collapses, and your spaceship is back in regular space-time (possibly in many pieces). The wormhole cannot become stabilized. But I don't need a stable wormhole. I need a bubble of space-time to occur in hyperspace. When the rockets fire, high energy gas is pumped into another bubble. That bubble moves away at a very high speed. The two bubbles will obey conservation of momentum and conservation of energy laws within hyperspace; the two bubbles are effectively hyperspace objects. Your next question I anticipate/hope will be, "how do you create a space-time bubble in hyperspace?" More realistically, your stubbornly persistent response will be "you can still create a wormhole, therefore FTL = time travel."

It's Christmas time. I implore you, don't deny me the question! Just ask it!

Dear Jason,

If Quantum Gravity is the key to understanding the relationship between Spacetime and Hyperspace, then we need to find large gravitational fields - Black Holes - to test this hypothesis. Although I think there is another time dimension, it could be imaginary time. How would that tie into your ideas?

I wrote a book on the issue of sending probes to nearby stars. I discussed some of the issues of wormholes and how they can be converted to time machines. This figure is from the book and illustrates how the so called twin paradox can lead to time travel. The two openings of the wormhole are illustrated in a spacetime diagram. The opening on the right is sent out at near light speed, and then accelerated back in the opposite direction at again near light speed. The numbers illustrate the local intervals of time on clocks near the two openings. So an observer travels from near the left face at near light speed, jumps in the right opening and emerges in the left opening at the coincident times. The winding through the worm hole continues and there is a piling up of this geodesic at a Cauchy horizon. Now if the observer elects to do this winding around the wormhole in the region future to the Cauchy horizon there is again a piling up of geodesics which approach the Cauchy horizon from the future. This is the region of closed timelike curves, or a time machine.

Now instead of there being a worm hole, we just think of these openings as any sort of stargate, even if it connects to another spacetime with c’ >> c. Since the interval between the right face and the left (the spacetime connection between jumping in the right opening and emerging from the left) is spacelike I can always choose a frame where the observer emerges from the left opening at a time coincident with entering the right. So the same winding up of paths will occur so there is a Cauchy horizon. The region to the future of the horizon will then be a “time machine,” or a region of closed timelike curves.

Dear Ray,

If quantum gravity is about closed loops in space-time, that just sounds too much like "reel to reel" physics; I don't see how we can rewind back in time. As for manipulating gravity in some convenient way, I tend to think of gravity as similar to an electric flux similar to E=epsilon*D where epsilon is the permitivity. In the case of gravity, G is a dielectric which is dependent upon the particular space-time in question; G should scale as (c'/c)^2.

Physics has probably gone as far as it can with what we can experiment with and look at from space; I am hopeful that someday we might come across some strange new material that might provide a way. I agree with Lawrence that it is probably impossible to create a stable wormhole and/or stargate. Perhaps if you try to accelerate one side of it, there is an ever increasing chance it will become unstable some how. If I can generate a space-time bubble in hyperspace, every attempt to make a stable wormhole will undoubtedly fail.

Lawrence assumes: GR --> FTL --> wormhole --> time travel = branch is impossible.

I argue that: GR --> FTL = possible;

however, FTL --> wormhole --> time travel = impossible.

I am not, as Lawrence suggests, "word-smithing". It is Lawrence who stubbornly grasps wormholes as a defense against FTL. The mathematics that he uses is only as good as the universe's willingness to obey it. All of Lawrence's mathematics are based on equilibrium conditions. Yet nature has demonstrated it's ability to manifest stable systems that are not in equilibrium. If FTL propulsion relies upon a delicate balance between our space-time and a temporarily existing FTL space-time, then traveling FTL for a few light years might be possible. Then again, I don't have the credentials needed to be able to stubbornly ignore the nuance that FTL propulsion can be accomplished without wormholes.

The wormhole is used as an example of any sort of opening in our spacetime cosmology that either bridges two regions in the universe or which connect with some other spacetime. In effect your idea amounts to a wormhole from our universe to another one, where you can travel at some c' >> c and then enter another wormhole to reenter our universe. You also presume that times in the two spacetimes are synchronized in some way, which is a broad assumption, but I will let that go for now. Exchange the terms wormhole for opening or what ever. Then if you can lasso an opening in our universe and accelerate it in the way I pictured with wormhole openings you then have closed timelike curves --- a time machine.

That is why FTL appears to be impossible. You are reaching for a wormhole. A wormhole is not necessary. You leave space-time with a bubble of space-time. That bubble is drifting in hyperspace. You don't care about the clock for hyperspace because that flow of time is occurring outside of the bubble. You can worry about getting lost in hyperspace; you can worry about the flow of time in the bubble being different from the flow of time in the rest of the universe. It is also reasonable to wonder how you create the bubble in the first place. You are over reaching; you don't need a worm hole. All you need is a bubble. The laws of the universe are telling you that a wormhole is too much to ask for. So don't ask for what the universe won't give you. Ask for something smaller that doesn't attempt to violate causality. A wormhole violates causality. A bubble does not.

When the HST first recieved images, the time-stamp, or physical date given to the images were of a couple millions light years ago, then HST recieved images of older period..etc..etc how come?

Why could not HST be tuned to just 3 seconds ago?..what if 3 seconds ago was really the big-bang, what if to travel away from the "now", a second ago or 3seconds ago, will br the big-bang, just by violating the spacetime continuum, may trigger the actual big-bang?

Our "now" has energy conservation to adhere to, send one molocule out of our "now" would have vast entropic consequences?

Nobody or anything has access in sight, sound or other physical process to any time domain other than "now"! It may be that we need to physically send the HST back to the Universe early moments, to actually confirm any evidence of a big-bsng. So how about entanglement?..if we could produce entanglement of a HST, then send it backwards, re-laying the information directly to our physical real-time..now?

The unphysical mode of transportation may be called an AVATAR via AVATATION, which is basically entanglement scaled up to relative spacetime!

The Hubble Telescope can see light from millions of years ago because that light just now arrived. In that sense, we can look at the past, but we cannot change it. There is a world of difference between looking at light from the past, and interacting with the past to change the present. It's not like we can look at light from millions of light years away, reach into the past of some star, and change anybody's future. The time machine that you thought you created using a wormhole is nothing more than a fancy inspection of history without causal interactivity. There are two different manifestations of the past.

1. Look at the past, but you can't change it; and,

2. Time travel to the past and change it, which is impossible.

The distant universe we observe is in the past. From an elementary perspective light observed from 100 million light years out carries information about a galaxy 100 million years ago. Things become a bit strange the further out you look. The velocity of a galaxy at a distance d is v = Hd, where the distance d is not too far out so a linear expression works. The z value is for z > 1 traveling faster than light as z ~ v/c for the radius of the FLRW metric then and now not too different. The most distant objects optically imaged are up to z = 9, and the CMB occurs out to z ~ 1000! This sounds a bit odd of course, for we are detecting photons from galaxies traveling faster than light. Yet this is a manifestation of a sort of frame dragging, where the stretching out of spatial surfaces of the universe is carrying particles with it. The objects are not so much traveling faster than light as they are commoving in a frame with spacetime. Further, since the speed of light is locally always the same a photon from a distant z > 1 galaxy will be commoved away as well, but it enters regions where that commoving is less and less until it eventually ends up to the telescopic aperture.

As for the three seconds, there is a bit of an ambiguity. We can’t optically image things before the surface of last plasma or radiation dominated scatter at the CMB. This surface of last scatter represents the state of the universe about 380,000 years after the big bang. The universe was optically opaque. If we improve our abilities to detect gravity waves and neutrinos we could detect the configuration of the universe much earlier. If the three seconds refer to three seconds ago from “now,” that is easy to see. If you observe the moon you are seeing it 1.3 seconds ago. The light from the sun escaped the photosphere about 9 minutes ago and most planets you see is from light which scattered off them anywhere from a few minutes ago (Venus) to a few hours ago (Saturn or Neptune for instance).

Dear Lawrence,

While we still disagree about FTL propulsion, some of what you posted might come in very handy. I've been wrestling with an effect that I didn't realize was called Frame Dragging. The space-time bubble within hyperspace could also be described as frame dragging for the FTL spaceship; the spaceship carries its own space-time with it. The transition from the spaceship traveling FTL to regular space-time might be explained with a variation of linear frame dragging. By the way, frame dragging suggests the existence of p3-brane or something resembling an aether.

Thank you. You made my day.

The frame dragging is done with certain criteria which prevent FTL. There was some years ago an idea about a big rip, and in this case the spacetime might permit closed timelike loops. The energy conditions are such that it could happen. Yet, that condition does not appear to be real, for the equation of state between energy density and pressure has to be w > -1. Data indicates that w = -1 within reasonable error bars. In the end it looks as if we are made out of meat. Now matter how you slice it up, if you try to link two points in spacetime by an interval with FTL you are equivalently travelling faster than light.

If a region of space can appear to carry a galaxy faster than light, then why don't we see that galaxy appear to rewind or travel backwards in time? There has to be something wrong with the very idea that a wormhole can create a bridge to the past via FTL simply because the past does not exist as a separate universe.

Dear Georgina,

For causes that change the potential energy, the effect propagates at the speed of light (or less). For an FTL cause whose effect travels FTL, we have to use potential energies for some FTL appropriate charge. Maybe Ray has some tacheocharges we can use. Of course, FTL would mean the electric and magnetic fields have to be weaker to account for a smaller permitivity and permeability.

There is space that the earth has passed through and space that it will pass through at different positions along the scalar dimension. The space that it has passed through is now vacant or filled by other matter. There is not another copy of the earth in that space that the earth formerly occupied.It is not therefore the past but aft space.

We could not travel to the past as it does not exist but it could hypothetically be possible to travel to aft space by slowing progression along the scalar dimension. Why hypothesise that there is anything there at all? Why not just have 3D space and no scalar dimension? Because although time can be argued to be an entirely biologically generated subjective reality experience it is necessary to have a physical scalar dimension to satisfactorily explain gravity, the experienced passage of time, the self construction of the universe (via continuous change of position along this dimension) and energy input for this self assembly process due to loss of universal potential energy, and to give mass energy.

We can not see what is within this aft space and whether it is vacant or occupied because instead we see an EM image of former configurations of matter in space that have changed or no longer exist. Likewise there is space that the earth will occupy afore along the scalar dimension. It is not possible to see what exist within this afore space, as all we can see is the EM image of former configurations of matter. No light travels back from afore space although gravitational effect can be observed. We are completely blind to that which exists afore and aft along the scalar dimension with the exception of the gravitational effect of matter in afore space, as our senses only detect stimuli from within 3D vector space.

According to this model the material universe (not the EM image) can be considered as one 3D spherical layer of the Megauniverse hypersphere. Other universe layers existing afore and aft, not past and future. This is the hyperspace. Travelling between universe layers would cause no temporal paradox because this is travel between different spaces not different times.

The reason for this model is that it explains the foundational questions in particular regarding time and gravity that the current space-time model does not. It solves the grandfather paradox and others. I do not see the logic in inventing a model, in order to permit faster than light travel, utilising modified space-time. When space-time has been found unsatisfactory in so many regards. Such as causing paradoxes and leaving so many foundational questions unanswered.

Frame dragging does not necessarily give FTL in the way you might think. A black hole frame drags. A Schwarzschild black hole can be thought of as a system which slides points on a spatial surface towards it. As the event horizon those points are moving at the speed of light. So any matter particle is moved with this, similar to a piece of wood on a current. At the horizon if an observer tries to escape they find they can’t, for to do so means they must travel the speed of light or greater than the relative velocity of points around them. This results in an event horizon. A distant exterior observer can’t observe any body reach the horizon, but is rather contracted and time dilated so they appear to approach the horizon ever more slowly. The observer falling deep into the black hole is carried along by the commoving set of points (frame dragging) at enormous velocities until the velocity approaches infinity at r = 0. That observer is trapped in this region until they reach the singularity --- there is no escape. Similarly with cosmologies there is an event horizon, though of a different character. The cosmological constant Λ determines a cosmological event horizon at r = sqrt{3/Λ}, which is about 10 billion light years out. We can receive light rays from objects out there, or as they were in the distant past, but we can’t send a signal back. So a mirror placed beyond the cosmological horizon will not reflect an image of our galaxy, even at a much earlier time. Similarly a mirror on the event horizon of a black hole will not reflect an image back.

Frame dragging which carries objects at v > c, here c measured locally and v measured at some distance through curved spacetime, generates an event horizon. This sets up unidirectionality for the transmission of information. You can send information to an observer in a black hole, but the observer in the black hole interior can’t send a return message. Similarly with cosmologies we can receive information from beyond the horizon, but we can’t send information to anything beyond it. With the Alcubierre warp drive event horizons are also generated, which have Hawking-Unruh like radiation that destabilizes the spacetime. Indeed this is common with FTL schemes, such as wormholes. There is a type of event horizon generated with renders the solution utterly unstable. Classically the solution can exist, but any perturbation of the solution, which can include a single photon, generates an event horizon and the solution is unstable. In fact the quantum vacuum can render it unstable.

Dear Lawrence,

Frame dragging is really required for FTL propulsion. Admittedly, that sort of takes us back to something like the Alcubierre hyper-drive. So I end up with a space around my FTL rocket that is quantum mechanically unstable; I'll just post a sign at the airlock that says:

Danger - Do Not Exit Spacecraft During FTL Travel.

Dear Georgina,

This idea that time is an interpretation just doesn't fit with observables. Even now, I only have two hours before I have to go to work. I never seem to have enough time. Clocks run at different rates, slower for spaceships accelerating to and from light speed. Reversal of time really requires "reel to reel" or "VHS cassette" space-time which really violates conservation of energy. If 4th dimensional energy make sense to you, then continue to work on it.

Dark energy is a case of frame dragging. The de Sitter metric term is g_{rr} = exp(Λt/3} and the gravitation is a = g^{rr}∂_tg_{rr} = Λ/3, which is pushing galaxies apart. Here Λ is the cosmological constant. But this sets up an event horizon. Sure space can pretty much do anything, but in frame dragging where v > c there are achronal null boundaries set up, such as the black hole event horizon. This is prevent you from making a round trip faster than light, or excaping a black hole.

I'm not surprised that dark energy is a form of frame dragging. While trying to explain FTL propulsion to a friend of mine, I did start to see that there would definitely be problems with how the clocks of the spaceship and the rest of the universe are related to each other. I figured that the relationship between the two clocks would be somewhat random as far as which one was faster. For FTL propulsion, any temporal relationship that might have existed between the two frames is probably lost in some uncalculable region of distorted space-time.

Don't worry, you'll still be able to make the return trip. You should have a good idea of when you'll get back. But you might need to take extra food with you in case your clock on board the FTL spaceship speeds up. Oops!

I've been thinking about the kind of gadgets I'm going to need to design a hyper-drive system. The laws of physics are indeed strange to work with. However, for the persistent and creative mind, here is the first:

Space-time generator: this device generates new space-time as a 3D volume. One might not notice that it was really generating new space-time. Since the universe is in fact expanding for unknown reasons, I decided to take advantage of that, and presume that new space-time can be created. I will, of course, tamper with its parameters.

Why do I need a space-time generator? Because I have to get everything inside of this volume of space-time to reach superluminal speeds; the whole volume has to move FTL. Therefore, I need to be able to control this volume of space-time.

Any thoughts? Come on! Somebody hit me!

Another gadget: The Holographic Manipulation Sphere. Every quantum particle and force inside of the volume of the sphere is mapped to a 2D manipulation surface on the sphere's surface area. Designer forces (quantumly entangled superstrings) are used to directly manipulate the particles and forces inside of the volume. This is, of course, an attempt to resist entropy. If there are air molecules inside of the sphere, surface forces would allow you to manipulate their movement. Attempts to force a lowering of the entropy might not work, but you could move molecules around and rearrange their position without adding energy to the enclosed system. I got the idea from black hole entropy.

Dear Steve,

Thank you for your encouraging thoughts. I have neither a doctorate nor the fear of letting others know that I don't understand something. Having said that, I am starting to suspect that the physics community does not understand entropy the way they think they do. A black hole is described as always having an increasing entropy. I relate that to a deck of cards that gets larger and larger. Since black holes are the ultimate in destruction, maybe they are not the best metaphor. But I can think of plenty of systems that can become ever more complex and more varied, which seems to be what entropy implies. But those same systems do not have to always end in destruction. In other words, entropy suggests greater complexity and more variables; but systems with more complexity can also become more orderly. For example, multiculturalism seeks to add more variety; it also seeks to create harmony within the whole. Another example is, we reach out to learn more, take in more information, because we want to find a solution to some problem. These are examples of increasing complexity/entropy, but with the objective of creating order. As in the example of a card game, we want to be dealt a better hand; depending upon how the game is played, we simply have to wait until we get the cards that we want.

If I have this diameter and volume ,thus I can calculate the fractal of spheres for our galaxy ,afetr if I insert the good serie I can find the center of our Universe and thus if I insert the evolution and the rotation I can find a better topology .In fact the rotation around the universal center implies a new real topology .The distance thus seemms very relevants because all turns and changes its position .Our datas thus must be re thought .The Universe seems different thus about distances between spheres .

FTL propulsion: it must be this way if it is possible, at all. Space-time obviously exists; some kind of hyperspace exists. You need a bubble. Inside of the bubble is your spaceship. The surface of the bubble converts energy from space-time to hyperspace/hyperspace to space-time. The bubble is charged with tachyons until, like an elevator, it finds another space-time or hyperspace. Just like the new "space" that causes the universe to expand, space can become charged with tachyons, causing everything inside to vanish into hyperspace; or, space can lose it's tachyonic charge and reappear in space-time.

Dear Lawrence,

On the other topic you mentioned that there might be two time coordinates. As it turns out, that might have to be the situation for a hypothetical FTL propulsion engine. When the spaceship enters hyperspace, it's time line becomes independent of the rest of the universe, thus two time lines. I assume these two time lines are independent?

The other time coordinate in superspace is a sort of mathematical construction. In 26 dimensions the square of numbers 1 through 24 sum up to be the square of 70. This is a metric, basis for how 24 dimensions can in a null setting exist in 26 dimensions with the addition of the square of 0, 0^2 - 0. If you change the sign on 0^2 (which trivially does nothing) then you have an anti-de Sitter realization. So this extra dimension of time is really a mathematical construction or something which involves modular systems for how quantum mechanics exists with spacetime physics.

So there are many universes, each with their own forward time-line or reverse time-line, but there is not a second time-line? I would have thought that a second time line would make it possible to relate the times between any two universe via a set of parameters that express how they're related. That would certainly be a step towards figuring out if there exists a force that could transmit between two universes. Without such an inter-multiversable relationship, it will not be possible to prove there exists.

On the other hand, the fact that space is expanding could be interpreted as a transformation from one kind of space to another; the fish in a pond might see the water level rise, but they don't notice the rain that condensed from water vapor. Since the velocity of light, c = sqrt(tension/density), one might wonder if the Cosmological constant energy density can be related to the velocity formula for our kind of space. Another kind of space might have different properties, different velocity of light, different Cosmological constant, etc. Since cosmologists are baffled by the quicker than expected expansion of the universe, maybe it's expansion occurs by a process unrelated to the Cosmological constant. In a similar way, the spacing of water molecules in a pond has nothing to do with whether the pond water levels will rise or fall. The Cosmological constant may simply indicate what kind of space- (time) is under consideration.

Dear Jason and Lawrence,

The more I play with ten, eleven and twelve dimensional models, the more I am convinced that there is a second time dimension - most likely imaginary time. It is related to the breakdown of a 12-dimensional Spin(12) (or SU(12)) into a 4-dimensional Spin(5) (or SU(5)) of Spacetime and a 6-dimensional Spin(7) (or SU(7)) of Hyperspace and a 1-dimensional U(1) (of Gravity?) and the 12th dimension disappears! Neat magic trick!

Such decompositions of groups happen on two levels. There is the 26 dimensional bosonic string, which results from a light cone condition on the 27 dimensional Jordan matrix algebra J^3(O). In 26 dimensions there are 8 dimensions for the vector terms an E_8 of vector valued fields, plus the corresponding spinorial fields and their conjugates for tow additional E_8s. These are 24 dimensions in general. There are three diagonal scalar terms, which with the light cone constraint reduces them to 2 independent degrees of freedom. Now the spinor fields are framed with the vector fields in a supersymmetric configuration, which reduces this "sector" of 24 dimensions to 8. With the 3 scalars this is 11-dimensions and the light cone condition reduces that to 10. So this is the relationship between the bosonic string in 26 dimensions and the supergravity multiplet in 10 or 11 dimensions. There is a corresponding result with vertex algebras on fields.

The decomposition of the 26 dimensions or the 24 dimensions on E_8s has its correspondence in the supergravity multiplet with a duality of 5 dimensions for AdS and the S^5 corresponding to conformal fields. The role of the spin(7) is the group which G_2 fixes a vector as a subgroup of spin(8).

Dear Ray and/or Lawrence,

I wish to consider the possibility that a volume V_st of space-time (3D spatial volume), could be transmuted/converted/transformed into a volume V_hs of hyperspace. Particles can be transformed; why not space? Just for the sake of discussion, please allow an imaginative example.

There exists a Schwartchild unit volume of space-time. The time portion is absorbed into the speed of light. The volume can be spherical, but not stack-able as a crystal. Let's call a unit of space, a Volium (Vm); let me know if there is a better name. A tachyon is used to transmute a volium of space-time into a volium of hyper-space: Vm_st + Tach Vm_hs.

A volume of space-time sustains a constant zero point energy E_st; a volume of E_hs might have more zero point energy subject to a function f(c'/c), where c' is the velocity of light for hyperspace. Since a tachyon is not supposed to carry energy, I will work out this discrepancy. I expect a unit volume of hyperspace to be larger than a unit volume of space-time.

What if tachyons permeate a region of space with physical matter inside? I want to presuppose that the volume of space-time can be converted, not into a volume of hyperspace, but instead be converted into a transducing membrane. Perhaps a spaceship inside is generating the tachyons. The tachyons are trying to transmute the space-time into hyperspace; however, there is too much energy content/particles to allow the transmutation. So a closed membrane, a bubble begins to form; this bubble is trying to minimize the surface area. When the membrane can completely enclose the spaceship inside, the space-time inside remains as space-time. However, the enclosing membrane might be able to make the spaceship vanish into hyperspace as a hyperspace bubble.

Any questions or comments?

Dear Jason,

Within the framework of my model and Second Quantization, the assumption is that bosons are an 11-dimensional reciprocal space that can transform one 8-dimensional fermion in direct space into another 8-dimensional fermion in a different direct space.

If you are relying on new dimensional spaces to transform the old 4-dimensional spacetime into a new 4-dimensional spacetime, then I think you need to play with all 26/27-dimensions of Lawrence's model. I haven't recognized that sort of structure in the first 12 dimensions - maybe I overlooked it because I wasn't considering the possibility.

If I truly have 12 dimensions (I think I do, but it could be a misinterpretation of my model), then I need to explain why M-theory is only 11-dimensional, and why String Theory is only 10-dimensional. Light cone constraints can reduce effective dimensionality by one, but I need to reduce it by two, To me, this implies TWO light cones. Perhaps there is an imaginary spacetime within hyperspace that is dual to our spacetime. My hyperspace has 8-dimensions, and these fracture into branes of lower dimensionality. One of the broken symmetries displays a (6+2)-dimensional tiling. That intermediate state is what Lawrence and I are discussing.

Let me tell you something about fast and slow. My girlfriend Margot made me go Christmas shopping with her; it took forever! She would do all this extra stuff. She had coupons and had to find the particular item on sale. Then, after we bought are stuff, she would check the receipt and find a mistake, something that would easily add on another ten minutes to a already boring shopping experience. That's when it hit me! Light is slow because it has to do a lot of extra stuff. But what extra stuff? Well, I know that permittivity and permeability are tied to the speed of light. Why should it take longer to produce a larger magnetic field and electric field? Does it help to break up your light cone into a permittivity and permeability plane?

Ray: I think I understand what you are saying with this. This is the field representation for the holonomy group. This does contain three families of quark and lepton doublets with the additional fields (H, s_f) which I am not sure I understand. However, this on a low energy scale might decompose into an SU(3) which is dual to the spacetime part as an AdS. This seems to suggest it could be an aspect of what I wrote earlier on, which I sort of re-edit here. The G_2 group is contained in SO(8) which decomposes into SU(3) with a 3 and bar-3. We can also extract SU(3) from the SU(4), which is also a subgroup of SO(8). The G_2 group is then a holonomy defined by the spin(7) in SO(O), which fixes a basis in S^7 sphere. The low energy decomposition of AdS/CFT with the AdS group SU(4)  SU(3)xU(1) should connect with QCD on the CFT end of the correspondence. The parton configurations are QCD ~ AdS_3 amplitudes for black hole (like) amplitudes which might occur. Above the TeV, or Higgs domain, there should be some partial recovery of the conformal renormalization group flow. At this energy scale there is expected to be some small amplitude or channel productions corresponding to quantum (super) gravity. Hence parton systems of quarks will have amplitudes for quantum black holes.

Quantum black holes as the AdS_3 ~ SU(3)xU(1) have color and electromagnetic charges, and can be classified according to their SU(3)_c and U(1)_em representations. In proton-proton collisions the allowed particles which can form the black hole are quarks, antiquarks, and gluons. There are then nine electric charge states which may exist ±4/3,±1,±2/3,±1/3, 0. The ±4/3 and ±1 charge states can only be formed by

quark pairs, the charge states ±2/3 and ±1/3 can be formed by either two quarks, or a quark and a gluon, while the 0 charge state can be formed by either a quark-antiquark or pair of gluons. The possible color states in a two parton scattering are

3x3 = 8+1 -> g_2 state

3x3 = 6+3

3x3 = 6+3

3x8 = 3+6+15

3x3 8 = 3+6+15

8x8 = 1+8+8+10+10+27S

Since black holes form representations of SU(3)c, they are predominantly colored, but can occur as colorless singlets. The four color scheme corresponding to SU(4) is then at lower energy the SU(3) color and the U(1) hypercharge or em charge. We should finish this and write it up in a short paper.

Dear Lawrence,

Does space-time wrap around a black hole the way scotch tape wraps around the cylinder? In other words, if I shine a laser down at the black hole onto something shiny, will it bounce back in a straight line, prior to the event horizon, or does the beam of light go round and round the black hole like tape is wrapped around the roll?

Of course, this could make it possible to save the astronaut who is whipping around the black hole for a few weeks. The poor astronaut would have lots of time to wait before his demise. However, if that is not happening, the astronaut has a few minutes to live before he is turned into space goop. We're an FTL starship able to fly in and somehow find that goop, I'm afraid that he would still be irreversibly dead, FTL propulsion not withstanding.

For FTL propulsion to be engineered, I require a second space-time with speed of light c' >> c. I have to put the spaceship inside of a protected standard space. That protected space then has to be interfaced with a containment surface made out of hyperspace space-time, a bubble. If the containment surface is completely sealed by the bubble, then the spaceship is, for all intensive purposes, removed from our universe. If it is not completely sealed, then the spaceship still exists in our space, but there is severe electromagnetic interference. In fact, a tiny breach, an antenna that is sticking out, is enough to hold that spaceship in our space-time. Passing through the bubble membrane might be impossible. If a nuke is fired at the membrane and detonates across the surface of the membrane, all that energy will be transmitted to the bubble with the spaceship inside of it. The explosion will give the membrane and spaceship quite a jolt. It might also take care of the antenna that was sticking out. There is also a chance that the membrane might fail to sustain its spherical shape, resulting in a crushed spaceship.

If the membrane is sealed tight, the bubble with the spaceship inside will appear in hyperspace as a hyperspace object. If the spaceship fires the thrust from its engines, that hot gas will become enclosed in a membrane of its own; the result will be equal and opposite forces. The bubble, with the spaceship inside of it will begin to accelerate, very quickly, in hyperspace.

Dear Lawrence,

I think that the temporal ambiguities related to FTL propulsion are coming from assumptions you make about wormholes. First, you are assuming that it is possible to create a wormhole that extends from the future to the past; you have introduced something that is impossible, something that violates causality.

Second, when you create this wormhole, you want it to maintain the same calendar dates and clock time at both ends of the wormhole; this is another place where you introduce a paradox. You want to maintain the same calendar date and clock time at both ends of a wormhole that you want to span time. You have built in a contradiction; when the model spits the contradiction back out, you take that to mean that FTL is impossible.

In order to model FTL propulsion, you cannot use a wormhole. You have to use a space-time bubble. The thrust from the FTL rocket will be packaged in tiny space-time bubbles that will carry momentum away from the FTL rocket bubble; the rocket will of course experience momentum in the opposite direction.

You cannot travel to the past because the past does not exist. You can't travel into the future with any hope of coming back to the past; you are allowed to stay in hyperspace for as long as you like.

You should be quibbling about how I can attempt to move a bubble of space-time through a medium or hyperspace that has not been proven to exist. I am expecting that criticism. I really want to try to resolve that criticism.

If you continue to try to argue using wormhole time machines and closed time like loops, then I will have to assume that you have a belief that is based in faith. I really want to understand when, how and why the temporal ambiguity occurs. Maybe we should tie a rope to the astronaut or just let the FTL spaceship fall in and then using FTL engines to get back out. I think we are approaching the point of ambiguity.

If you put a mirror near the event horizon of a black hole a small distance from the black hole event horizon, with some means of keeping it at a fixed proper distance from the BH, a photon will reflect off, but not with the same energy you send it in with. The “placing” of a mirror near the event horizon is theoretically a technique for regularizing fields in curved spacetime. This is used in the Rindler spacetime near the horizon to compute an entropy S = (1/96π^2)(F/d), in the limit d - -> 0. This involves some sensitive mathematics I will skip here. Yet the purpose of having that distance d is to estimate how energy or entropy varies as d becomes small. To make a long story short a mirror will reflect no energy back out in the limit it approaches the horizon. This then illustrates the quantum fields do not diverge in some bad way at the horizon.

Space does not wrap around a black hole in the way you appear to think it does. If you start out with a spatial surface it intersects the horizon and the subsequent evolution of the spatial surface evolves so subsequent spatial surfaces are attached to the same intersection. So the spatial surface sort of folds in around the black hole, getting closer to it. I attach a couple of diagrams of this. The first illustrates what happens to a spatial surface around a black hole which forms and then quantum decays. The second illustrates a similar thing, but where the spatial surface occurs before the black hole forms.

Unfortunately you idea still will not work, because you are ultimately propagating fields in our spacetime on an interval which is spatial. General relativity can always transform these into backwards time developments of information --- or time machines.

If I drop a perfectly elastic ball in a gravity field, it should bounce and return to my hand with the same energy it left with. If I beam a laser to a mirror that is some distance d from the event horizon, it should return to my detector with the same energy it left with; when d reaches zero, the beam doesn't return at all. In between, the photons will gain more energy, as it falls into the gravity field, and then lose that same energy as it reflects back to the detector.

When you said, "Yet the purpose of having that distance d is to estimate how energy or entropy varies as d becomes small. ", were you suggesting that the black hole is permanently siphoning off energy from the photons, leaving them enervated when they bounce back to the detector which is positioned next to the laser?

The attached figure, which I think I have attached before, illustrates two openings into a wormhole or some other “passage” between them. It matter little what the passage is through the openings, but rather that if you drop into one opening you emerge from the other. A photon or highly relativistic particle or observer can wind through these by dropping into one opening and emerging in the other and then traveling back to the first opening. Then as this diagram illustrates if one opening is boosted or accelerated outwards and then back you end up with a region past the Cauchy horizon with closed time like curves.

A mirror in curved spacetime or under acceleration is a canonical problem in general relativity and for quantum fields in curved spacetime. You might agree that if the mirror is past the horizon no photons are reflected back. This holds for the mirror on the horizon as well as just above it. It might sound a bit odd, but general relativity does that to you --- it gives results which are not always expected.

Dear Lawrence,

We really don't know how space-time is implemented; nor do we know under what conditions it would fail to work the way we expect. I'm afraid your opinion that FTL propulsion = wormholes = time travel is hard-wired.

On the mirror near a black hole problem, I wanted to try to go step by step, down to the event horizon, of what the falling observer would see, and then compare that to what the far away observer would see. Since a black hole is likely to accelerate falling mass-energy to relativistic speeds, I expect such particles to whip around the black hole many many times before falling in. I read some where that you can watch your buddy fall into the black hole for a very very long duration, like decades or longer. Your astronaut buddy would be killed within minutes of falling in, ripped apart by gravity waves. He would be forever lost. However, we could watch his image of a few minutes last for decades. Let's say that ten years after he falls in, an FTL spaceship becomes available. If you tried to swoop into the gravity well to save your buddy, you would only find an optical illusion. You would never be able to undo his death.

Since you believe unwaveringly that FTL propulsion = wormholes and time travels, I'm afraid that logic will not convince you. I did the best I could.

The mirror gedanken experiment largely applies for radial inward directed photons. A particle can be in a stable orbit around a black hole for a radius r > 3GM/c^2, where the horizon is at 2GM/c^2. A particle between r = 2GM?c^2 to 3GM/c^2 will not remain on a stable orbit, though with a force (say turning on a rocket engine) escape is possible. It requires some effort to work through this.

There are two problems here as I see it. As I read what you write it is somewhat evident that you are not deeply familiar with general relativity, and lack a working knowledge (you can solve problems) in general relativity. If you were you would not write some of the things you do. The other problem is that you are not really asking an appropriate question. Foundational questions involve some resolution to a paradox or contradiction. This was what Einstein saw when he imagined himself on a reference frame moving with an electromagnetic wave. He realized on such a frame you would observe an oscillating electric and magnetic field at rest, instead of propagating as a wave according to Maxwell's equation. Similarly Planck saw a conflict which arose from assuming molecules in a body were harmonic oscillators with a continuum of energy values that lead to a flawed black body radiation spectrum. We are faced with a paradox or contradiction with quantum gravity. Now in trying to show that FTL exists you are not solving a paradox, but rather insisting upon imposing one. You appear to think that by saying the FTL motion occurs in some other space or spacetime that the problem is removed, but you are not considering how this ultimately involves the propagation of information in “our” spacetime in a way which results in these contradictions. There really is no way you can finagle your way out of this in a consistent manner.

I clearly can’t disabuse you of these ideas you have. However, if you look at the real physics and come to some awareness of the real problems we face you will come to some far greater intellectual depth of understanding than what can be had by trying to make science fiction ideas “real.”

Quantum mechanics acts one way when we're not looking, and another way when we look (measure). You say that information can't propagate faster than the speed of light; certainly not if it's being transmitted on an electromagnetic wave. But certainly, nothing in space-time can travel faster than c. What if FTL propagation can only occur if it is hidden from space-time, if space-time can't see it.

step 2: fly to a distant star;

step 3: return to space-time;

step 4: scoop up a sample;

I found a better way to approach the hyperdrive problem. Let us say there exists a hyperspace with its own speed of light c'. The laws of motion are similar to ours. I have a hyperdrive engine that, when powered up, it creates an interface field around the spaceship. Yes, we're back to the bubble. The closed surface of the bubble allows the spaceship to be effectively carried inside of the bubble. The bubble exists as a hyperspace object/material/particle, with a pocket of space-time inside of it.

When the rockets are fired, they have enough energy to accelerate the spaceship up to about 0.2c in space-time. When this energy passes through the bubble interface, energy is conserved. This allows the bubble to achieve a velocity of 0.2c'. The bubble CAN'T travel faster than the speed of light, c'. As a particle/material of hyperspace, it is required to obey the laws of hyperspace. The fact that a pocket of space-time is hiding inside of the bubble is none of hyperspace's business.

When the spaceship enters hyperspace, it is removed from space-time. All that remains is how do you map space-time information content into a hyperspace object. Whatever the mass content inside of the bubble, hyperspace sees a bubble with mass content m' = m (c/c')^2.

Information cannot propagate faster than the speed of light. But it can be mapped to a faster space-time. This is very similar to how computer programs run faster on a faster computer.

Time travel still cannot be achieved. You can't see the future and you can't travel back to the past. Also, energy is conserved.

From the perspective of an observer in our spacetime information travels faster than light. If you did a test with a small system of particles you would find they drop out at a point or region x and then materialize at y faster than light. From your perspective information has traveled faster than light.

A hyperdrive wouldn't be of much use if it didn't give the appearance of FTL. You're supposed to go, "Holy Crap! That ship went v = 50c!!!" But it did so without using the mechanisms of space-time that provide for motion. It did so by using the mechansims of motion of some other space-time (hyperspace). The real trick is, how do you create such a bubble that can interface between two space-times whose speeds of light are radically different. How do you map information content to a faster computer (space-time)?

Now replace step 4 with the letters between Alice and Bob and let your FTL propulsion spaceship act as the mailman between the two. Then using Tolman’s argument (http://en.wikipedia.org/wiki/Tachyonic_antitelephone) you will be able to implement an “anti-letter” (or “anti-telephone”) communication between Alice and Bob. Causality may not be disrupted for the driver of the FTL spaceship (your argument), but it can be disrupted for Alice and Bob (Tolman's argument).

But i have red that spacetime itself can go faster. 'Inflation' can propagate with speed faster then the speed of light. And spacetime around a blackhole can flow at bigger speed towards the black hole then the speed of light. Otherwise a falling person can't fall into the blackhole.

Can we jump from an inflating piece of spacetime to a stationary piece of spacetime? Can those pieces of spacetime glued together in some way?

Peter: Those are some of examples of cases where we know that FTL can occur. I want to pull a spaceship out of space time and into hyperspace. If I use an interface bubble with a volume of space-time on the inside, and a hyperspace space on the surface, I might be able to slip into hyperspace where the laws of motion operate at a higher speed of light c' >> c. However, I'm getting a lot of flack from people who say (1) information can't travel faster than light (even in a bubble), (2) the existence of our space-time makes another space-time impossible, and (3) Alice and Bob can't dodge time travel (for reasons that don't make a lot of sense).

Why can't I expect nature to create coaxial space-times? In other words, for those who like branes, there exists a set of space-times, all of which have the same center, like a balloon within a balloon within a balloon. This sets us up to be able to say that information cannot travel faster that c, for that particular brane or space-time that it's on. The light/photons/electromagnetic radiation on one brane are incompatible with the light/photons/E&M on another brane. Energy is conserved for transactions across two branes. In other words, you don't create or destroy energy by going to another brane. But you do go farther on branes with a higher c.

I am really starting to suspect that the velocity of light, as an absolute, has become an ideological bedrock, a belief or religion that physicists can cling to. The speed of light is sacred and is the only thing that is constant in a world where too many things change. I am sorry to have to disturb something that is so near and dear to so many of you. Yes, I understand that all of the evidence says that space-time is experimentally sound; ok, I got that. But FTL propulsion has never been tested, so we have zero experimental results. Besides, by creating a warp bubble, I can make sure that the warp bubble obeys its own space-time limitations. The information content inside of the bubble is hidden from space-time, so FTL propagation of information might be suspected, but can't be restricted by our space-time.

I am really interested in hearing a logical argument of why FTL propagation of information is absolutely impossible. Everything I've heard so far including the antetelelphone, doesn't even leave me with a nagging doubt. That's unusual.

A spatial surface can stretch in a way so that points at some distance relative to a reference frame are moving faster than the local speed of light. There is one catch though, an event horizon occurs. This prevents a "return trip." A black hole is of this sort. You can think of spatial points sliding inwards at an ever greater speed so that beneath the horizon radius they are sliding in faster than light. However, the occurrence of an event horizon prevents any information inside this trapped region from being communicated to the outside.

I thought I would illustrate a type of FTL. This is not exactly a spaceship, in fact it is not something you exactly ride. Yet there is something faster than light, in a manner of speaking, it is the speed of mind. This last summer we observed the 40th anniversary of the first Apollo landings on the moon. I think it is probably fair to say that in the universe biologically active planets are fairly rare. Rarer still are such planets which bring about the evolution of intelligent life, who in turn build a machine that is capable of transporting representatives of their kind to another planetary body. I really think this is a very unique occurrence in the universe. For a flat infinite spatial universe anything which is not impossible is ultimately mandatory. Yet I think this is extremely exceptional. Further, we have extended our observations of the universe to the greatest distances imaginable, and can peer into the early universe. This speed of mind is not only a type of FTL, it is also a time machine of sorts. We have also looked in the opposite direction, into the smallest scales imaginable into the heart of the hadron, and hypotheses about what lies far beneath that. So a little piece of the universe has evolved the ability to observe the universe, and it is pushing the envelope further outwards and inwards with the conjecture that at some ultimate juncture the two, the cosmologically immense and the infinitesimally small quantum, should merge into one. Astounding! It is astounding to think that not only what we observe exists, what we think may exist, but that we are here to observe it and to think about it. Here we are, these frail pieces of meat made of polpeptides, lipids and polysaccharides, with the property of self awareness, who can think mathematics and music, who are composing the cosmic symphony by observing how the universe dances. Astounding, and this speed of mind is ultimately based on imagination ---- Imagine!

I guess the physics community just needs time to catch up to the hyperdrive/imagination. But seriously, you should look at stretching a sheet of space-time along the c, speed of light, axis; you know, the axis you didn't think was there. Of course, this generates a continuum of space-times which obviously can't be right. For some reason, only a handful of space-times can exist without getting in each others way. I suspect you will end up with 3 or 4 space-times, each with a unique c and h. At least one of them is empty.

When you approach the multi-verse this way, you will find that the laws of nature automatically prevents time travel from occurring. The statement "information cannot propagate faster than the speed of light" subordinates to

"each space-time has its own information content which cannot propagate faster than the speed of light for that space-time; the relationship that maps information content between space-times is related to the force that spans the group of space-times."

Assume you have points x and y, where by some mechanism (any mechanism!) a particle can jump through and between them faster than light, you have a time ordering ambiguity. One observer can see the particle enter x and leave y, while another observer can witness the paricle leave y and then enter x. This is very canonically basic to the nature of special relativity. This is something very clear to mid-level undergraduate students. With a little more sophistication you can show that by moving one of the points around that you can get closed timelike curves. Closed timelike curves are a manifestation of what we might call a time machine.

I attach a figure which illustrates what an observer detects when two flash bulbs ignite at the same time. The light fronts meet at the midpoint between the bulbs as seen by an observer at rest. Yet for an observer which travels at some velocity v the light fronts reach a point other than the mid point. This is equivalent to saying the moving observer will see one bulb flash before the other, and the ordering of these events is frame dependent. This is related to how the occurrence of the two flashes can't be causally connected, where one bulb causes the flash of the other bulb.

A wormhole is a solution to the Einstein field equations. The solution is not stable under any perturbation. Anything which attempts to fly through it perturbs the wormhole so that it becomes two black holes. This can include a virtual fluctuation in the quantum vacuum. So moving the wormhole is problematic, and indeed its physical existence is problematic. Yet, let us assume there is some way of protecting it from such perturbations. This is a Star Trek related thread, and the show proposed something called Heisenberg compensators --- which can't exist, but it makes for interesting fiction. So in order to maintain the existence of something which can’t exist we posit some techno-magic which also can’t exist. In that case moving one of the openings of the wormhole can result in closed timelike curves or a “time machine.”

The energy issue with wormholes, and other solutions which result in FTL causality or time travel, is less to do with a violation of conservation of energy, but with how they violate an energy condition on the “time-time” component of the momentum energy tensor, called T^{00}, which in the averaged weak energy condition satisfies T^{00} >= 0. The energy is computed from

E = ∫d^3x e^0T_{00} or more generally E = ∫d^3x t^aT_{a0}

For t^a = Nn^a + N^a, N = lapse function, N^a = shift and n^a a normal vector on the spatial surface. If the energy condition is violated there is then a negative energy E < 0, which has no lower bound. This results in trouble with quantum field theory, because the wormhole is generated by some mass-energy source. This does not disprove the existence of wormholes or related solutions, but it brings up problems of a large magnitude and causes physicists to think these things can’t exist. Your idea is really a form of Krasnikov tube, which also violates these energy conditions.

I looked at the attachment; I don't see how it supports your argument that FTL is impossible. Just because an observer sees the effect happen before the cause is irrelevant, I repeat, IRRELEVANT to whether or not time travel is possible. Go to an observatory and look at a star that is, let's say, a million light years away. It's like you're connected to that star by a hypothetical reel of film. You see the end of the reel; the star is still generating the reel/film/continuous flow of visual images. If you get in a starship and hyperdrive up to the star, you approach the star's present day. It's like fast forwarding the movie to present day on that star. When you reach the star, you are allowed to interact with the star and create causal events on it. But you cannot change anything on the hypothetical reel/film that extends back to the observatory.

You really need to step back and look at the GR and ask yourself if it makes sense. The mathematics might be telling you something that, upon thoughtful consideration, is really misleading. You are treating space-time like a movie film. You sit in the movie theatre, you understand that you cannot interact in real time with the characters in the movie, but you do not understand that you are allowed to contact the movie producers and try to change the latest filming. That's what FTL does, it lets you fast forward the "film" until you reach the real time filming.

I know what you're doing wrong. When you create a wormhole, you are, in effect, jumping from one frame of a movie on a reel, to another frame. But you are confusing this with time travel. Time travel means that you can change the past. What you're describing is simply moving along the film of a reel to reel. You can't change the movie film because it's already been created.

Relativity enables calculations and predictions of the EM illusion to be accurately conducted. But it is still an EM illusion and not material reality. The image may be seen spread over time to be observed by different observers at different positions in different orders. The observed event is not actually happening whenever it is observed.

The material universe and matter within it can be interacted with only at the 4th dimensional position where it actually physically exists not wherever-whenever it is seen. There can be no time travel because the matter only has one material existence, it does not have many existences in different times despite observation to the contrary.

There is no past or future or absolute present realm in material reality. Just a succession of patchwork subjective reality experiences formed from observation of EM radiation that has taken various lengths of time to arrive at the eye.IMO.

I'm not some brown nosing undergraduate who just wants an A no matter what nonsense he's asked to believe. Maybe you can't just move the endpoint of a worm hole around any old way you please.

I would also advise that you watch Susskind’s lectures on relativity, where this link is to the first lecture. Leonard Susskind starts out on a very elementary basis and works up to fairly advanced material, but throughout he keeps this on a pretty accessible level. There are loads of insights here, and when I am writing I often have his lectures running in background, and when some matter of subtle interest comes up I will shift my attention.

I can only advise that people learn the real stuff. There are a fair number of people who post here who either appear to have little real understanding of physics, or who are examples of the adage, “A little knowledge is a dangerous thing.”

The last already approved post is by Jason Wolfe in August. His subsequent November post did not yet find approval. Instead to just join widespread skepticism towards time travel, warp drive, etc., I hope being able to add a premature answer to what I consider a key question:

To what extent do mathematics rule reality?

My answer is:

Some generalization are most likely not justified and must be excluded.

The claimed general covariance says coordinates do not a priori exist in nature. Some physicists seem to take this literally and arrive at negative energy, etc.

I doubt that it is reasonable to infer from claimed general invariance under differentiable coordinate transform that there are no absolute references in nature. Is it really reasonable to ignore the limitation of pressure to positive values if we are using an absolute reference? Aren't negative distance and measurement of negative already elapsed time unreal?

Even if it would be possible at all to build quantum computers, warp drives and the like, I did not have any chance to experience this in my lifetime. I can only hope that the possible failure of the search for SUSY by means of the LHC will soon give rise to more respect towards those who share my views on some very foundations.

As I indicated in topic 604, I found out that numbers must be considered like measures that relate to "one" rather than pebble-like points, and Vaihinger's "as if" is perhaps sufficient, simpler, more honest, and less confusing as compared with Cantor's naive set theory, AC, quantification of subspaces or sublocales, the distinction between open and closed subspaces, and all that.

Dear FQXI Community,

I wouldn't waste everyone's time on this subject if I sincerely thought I was wrong. FTL propulsion, if it is possible at all, it most likely requires that some other universe's laws of motion be used; our space-time simply requires an unreasonable amount of energy (Alcubierre drive) to accomplish this task. There are criticisms that my approach to FTL propulsion deserves: (1) how do we find another space-time? (2) Why don't we notice other space-times around us? (3) How do you create a hyperspace/space-time bubble? (4) Information can appear to propagate faster than c. But the argument that ALL FTL propulsion methods amount to wormholes; and all wormholes, by the mathematics of space-time, are allowed to have endpoints that can be arbitrarily moved in time and space like a TARDIS propulsion system, is to throw the baby out with the bath water. There are too many assumptions within the FTL propulsion equals time travel argument, that we unnecessarily close the door to a physics that may yet be possible.

What happens if we say that FTL propulsion can only be possible under the following restrictions: (1) time travel is restricted and impossible; new time lines cannot be generated. (2) Energy must be conserved. (3) Other space-times and hyperspaces must be hidden in such a way as to agree with observations. At least this approach gives the physics community something to think about while we wait for a lucky break/new discovery/unlucky alien that crashes into the bad neighborhood, "Earth".

General invariance principles mean that any frame bundle or coordinate system can be transformed into another one with the preservation of some quantitiy, In relativity this is the proper time, or the invariant momentum interval --- or mc^2. These are pretty benchmark aspects of modern physics.

Dear Lawrence,

General invariance principles, Lorentz transformation, apply to a set of coordinate system transformations that preserve some quantity, the speed of light, c. These are all established mechanisms in GR, they have been confirmed in the laboratory. In the pursuit of an FTL propulsion theory, one that really can't be confirmed by experiment at this time, we have to be clever in how we proceed.

For a group of standard model particles and forces, I can't be entirely certain that I can just move them into another space-time/hyperspace. I suspect that they are already part of space-time. If I were trying to transplant a tree or a shrub, I have to dig up the dirt around it; I have to get all of the tangled roots that are part of the plant. I want to enclose the particles/spaceship within a mathematical closed surface/sphere. Inside of that closed surface/sphere is normal space-time. The surface itself will begin to remove the particles inside from the rest of space-time; E&M forces will eventually be blocked at the surface.

The surface itself will be made to interface with another space-time/hyperspace. The sphere itself will become a "particle" inside of that hyperspace. Relativity will still be enforced for the "particle"/sphere, but for a speed of light of hyperspace, c'. That means that we can still use gamma = 1/sqrt(1-v^2/c'^2), but the speed of light will be that for hyperspace, gamma. The flow of time will be judged according to gamma now, not c. Inside of the sphere, the spaceship or particles might simply observe a shroud of darkness. If the spaceship fires a projectile/missile at the inside surface of the sphere, that projectile will take some of the surface with it, and travel very rapidly through hyperspace in its own interface surface/bubble. If the bubble collapses, the particles/spaceship will still be propagating at some fraction of the speed of light, only without the bubble, the speed of light used is just c, not c'.

While the physicists decry that the particles/spaceship appeared to move FTL, the surface/bubble around the particles/spaceship prevented the actual witnessing of FTL. Since anything inside of the bubble is considered to be removed from space-time, invisible and non-interactive with the rest of the universe, then observations of FTL, based on when the spaceship left and where it arrived, are indirect. An indirect observation is sufficient to dodge General Relativity because space-time can only enforce its laws upon what it can see and what can interface with it.

Jason. I am sure you would not waste everyone's times if you though you were wrong. The problem is that you think you are right, but wrong nonetheless.

There is a pernicious aspect to the question of closed timelike curves and faster than light propagation of information. It might be underlying physics quantum fluctuations are so enormous that everything breaks down. Suppose that underlying all of physics everything is utter chaos. This would presumably occur near the Planck scale. I attach again my image of a wormhole under an acceleration or boost. After the Cauchy horizon what I portray is the wormhole is transformed into two black holes. What I propose is there is some symmetry breaking system which prevents the system from becoming a time machine. Now this might seem to conform to your idea of FTL without time travel. It does sort of. Yet remember that the time aspect of a metric is multiplied by the speed of light squared. This is why general relativistic tests involving the curving of light around gravitating bodies is more readily observed than more subtle orbital perturbations which involve spatial corrections. Now suppose that this displacement of the wormhole opening is due to a quantum fluctuation. This would then correspond to some level at which quantum fluctuations can “jostle” particles around faster than light, for in this case the wormhole itself is a type of quantum instanton, but where a symmetry breaking mechanism prevents this from becoming a system which propagates information backwards in time. Then on a somewhat larger scale the spatial impact of this is apparent and the occurrence of large wormhole becomes blocked by the same symmetry breaking mechanism. This symmetry breaking mechanism is what generates certain bubbles in a superspace, say the 10-11 dimensional supergravity space or the corresponding 26 dimensional Lorentzian geometry of bosonic strings, which have a frozen in direction of time. The Cauchy horizon is then a sort of D-brane generating mechanism on a scale of energy below the Hagedorn temperature which valences the larger scale world from this sort of chaos.

I am not proposing this as any sort of truth, but as something to think about.

Lawrence with respect,

the real thing is fraught with paradoxes and nonsense. Belief in time travel is in my mind no better than belief in any other nonsense even though there is supporting mathematics and theory. The paradoxes show that the interpretation is incorrect when taken literally (or whatever the mathematical equivalent of that term is). The correct interpretation has to vary from that which is widely accepted by modern physics.

No matter how well acquainted one is with general and special relativity the paradoxes and nonsense will not disappear because the problems are built into the the models. You appear to be claiming that because relativity has proven to be mathematically and observationally irrefutable it therefore must be accepted as the literal truth. You also seem to think that someone not accepting that "truth" lacks sufficient education to comprehend the theory. That seems to be a kind of scientific fundamentalism which like religious fundamentalism can not accept that alternative interpretations might have any worth or possible validity.

I do not and will not accept that "literal" interpretation, as the consequences are unacceptable. Eternal pain, fear, suffering and atrocity. Every horror fixed in time forever. In my opinion the image of an event may continue to be observed but the material reality happens once within quaternion space and then no longer exists within quaternion space. The matter having changed and moved on to other configurations and events. That which is observed is not material reality itself but a subjective reality biological simulation formed from an electromagnetic image input. That experience is not the same as the external existential material reality.

Dear Lawrence,

If I thought I was wrong, I wouldn't bother pushing the idea. I think the conversation has merit and value, even if just to engage in a battle of minds and wills. Of course, I am right. :-)

From what your saying, it sounds like wormholes are some sort of entanglement between to black holes. When the wormhole is jostled, it collapses into two wormholes anyway.

My bubble idea is partly based on the following possibility. Our universe/space-time is a hyperspace object, something that exists in hyperspace. The Big Bang is therefor an explosion that occurred in hyperspace. Therefore, if there can be one hyper-space object, then why not two or many? We are told that our universe is expanding; I don't think they know if it expands at the speed of light. I presuppose that something like a tachyon causes space to remain excited, a hyperspace. If that tachyon is given off, then the space becomes standard space. Certainly nobody has proven this very speculative notion, but it gives me something to work with.

Next, without using any black holes, one simply uses tachyons to excite a region of space. That excited region of space becomes an object in hyperspace. Objects in hyperspace can move around a lot faster, but are still bound by their own speed of light, c'. Closed time-like curves are an attribute of wormholes and the manipulation of space-time.

I think you are visualizing FTL propulsion as a break away from the space-time continuum, like an off-ramp that separates from the main highway for a few miles, and eventually has an on-ramp that recombines with space-time. I think in your mind, you are visualizing FTL propulsion as just a temporary departure from a point in the past, that recombines with space-time at a point in the future; the way a coffee cup has a handle that is still connected to the cup at the top and the bottom, but is separate in the middle. To you, this still looks like a wormhole. While quantum particles might be able to trace out a world sheet that lasts for a few milliseconds, an FTL propulsion bubble may remain in hyperspace for such a long time that it truly becomes a separate universe unto itself. But how long an FTL propulsion bubble remains in hyperspace is probably not sufficient to force it to obey the laws of space-time.

If virtual particles can hide below the Planck constant, h-bar, to facilitate the mechanisms necessary to make E&M worm, then why isn't it possible to remove an object from space-time itself?

I think that tachyons are held on M2-branes in black holes or shove off "to infinity" in the big bang. This probably provides a form of chronology protection. The string world sheet, or in general the n+1 dimensional world sheet of a Dn-brane valences the world from this sort of chaos. As such the occurrence of closed timelike curves or propagators which are faster than light is shielded from the world and don't exist on a large scale. It is similar to statistical mechanics, where a system with a small number of modes, or atoms, can exhibit spontaneous entropy reversing processes. Yet these become highly improbable the larger the system examined. In much the same way I think that FTL, wormholes and closed timelike curves are almost infinitesimally probable on a macroscopic scale.

Dear Lawrence,

We're both speculating about how FTL phenomena will manifest in the physical universe. It sounds like you are saying that FTL must manifest as closed time-like loops. To me, closed time like loops sound like a non-divisable unit particle of a time-machine/wormhole, a conditioned response you have when FTL is discussed. If quantum mechanics appears to spread its eigenvalues over time, it's not because it is dangling a time machine in front of us, it's because the universe, quantum mechanics has the ability to keep its options open until the last minute. There is not backwards causality at the same location. If an experiment suggests that there is, it only looks that way. You can't build a time machine out of it. The best you can do is build an ambiguity machine or a hedge machine.

A system that incorporates FTL particles/forces/tachyons, at best, you might get to see the effect before the cause, but you can NEVER string those together to create a time machine. FTL phenomena probably has to be removed from view by the universe, and held in some ambiguity field, or more likely, the mechanisms are hidden from view. FTL propulsion technology will probably give you cloaking and even shielding. It might make you think the effect happened before the cause, but you can NEVER EVER EVER undo the cause just by seeing the effect first.

Dear Jason,

You say:

“It might make you think the effect happened before the cause, but you can NEVER EVER EVER undo the cause just by seeing the effect first.”

This is a variant to the so-called Novikov consistency principle. What it entails is the loss of free will, or imposing unphysical GLOBAL constraints on the LOCAL physics.

FTL is simply a dead horse. Mathematically, inertial frames have only 2 transformations possible: Galilean transformation (with separate space and time and no speed limit) or Lorenz transformations (with a speed limit). We live in a universe with either no maximum speed limit, or with a speed limit.

The validity of Maxwell’s equations demands the second solution, end of story.

Lawrence B. Crowell wrote on Jan. 2, 2010 @ 21:44 GMT
This constrain by Novikov is a problem which Kip Thorne raised. He proposed that mechanics was such that closed timelike curves could never exist, by imposing various conditions on systems. Of course with classical dynamics there are integrable systems which do have closed orbits, so they recurr at a point in space, or chaotic ones which comes within an epsilon of every point on the energy torus, including the initial point. If there is some time flipping or reversing property, then closed timelike curves are inevitable.

The issue of faster than light travel, and equally time travel, did come up from Thorne's work on wormholes. This stimulated interest in a range of similar ideas, from the Alcubierre warpdrive to Krasnikov tubes. These however all run into a set of problems which introduces far greater difficulties. The violations of the Hawking-Penrose energy conditions makes quantum mechanics inconsistent. This also leads to time travel (closed timelike curves) which leads to logical or causality contradictions.

So instead of Novikov's constraints it is clear that the local principles of Lorentz invariance on any local frame holds on any physical manifold in general. What is not clear in physics is exactly how this chronology protection rule is enforced. So there is an interestin in looking at these strange solutions which give faster than light and time travel. Yet the interest is not so much in getting NASA to build up a warp capable spacecraft, but rather in trying to understand something about the foundations of physics.

Dear Florin,

You said: "FTL is simply a dead horse. Mathematically, inertial frames have only 2 transformations possible: Galilean transformation (with separate space and time and no speed limit) or Lorenz transformations (with a speed limit)."

Perhaps you missed it. For FTL to work, you have to remove the spaceship from space-time entirely. If I remove it from space-time, then a Lorentz transformation can't be performed. Using the train experiment when deriving special relativity, the passenger aboard the train looks out and sees nothing, darkness. The observer watching the train go by sees it vanish; no comparison can be made. It's not a dead horse because the Lorentz bullet you shot it with doesn't work for objects that vanish from space-time.

Dear Lawrence,

I acknowledge that you don't believe that wormholes are stable. I think you are pointing out that quantum mechanics becomes inconsistent when Alcubierre warpdrives and Krasnikov tubes are used. That underscores all the more reason to isolate the two universes from each other, space-time and hyperspace. You point out a reasonable issue that we don't know how chronology is enforced. A causal event might be one particle transmuting into another such that forward transmutation is not unusual, but the reverse almost never occurs naturally. Once you take an Avagadros number of these mostly one way interactions, then the forward flow of time is unavoidable. The reason you can't get time travel is because you are faced with impossible probabilities that everything in the universe just reverses itself for no apparent reason. But if you have tachyonic forces and particles racing around, transmitting information, you get to act before the rest of space-time can do anything. However, you are still faced with impossible probabilities when you try to reverse an Avagadros number of one-way reactions.

For a volume of isolated space-time, with a spaceship inside, that is returning to our universe/space-time, are you suggesting that the quantum mechanics and/or time, does not match up upon arrival?

I can understand your concerns about the quantum mechanics of hyperspace. I can also understand your concerns, which you haven't raised yet, about a bubble that has space-time in the middle and hyperspace on the outer surface. But quantum mechanics by it's unpredictable nature, lots of eigenvalues, has flexibility already built into it.

Dear Florin,

The anti-telephone is puddle of bath water and babies. We all agree that time machines violate causality and generate paradoxes. How can I say this nicely? The physics community needs a less clunky and more elegant way to explain why something is impossible without making everything impossible. In other words, you, Lawrence, and all the other physicists are throwing everything you can think of, kitchen sink included, at a paradox in order to make sure that nature won't make a mistake. Don't worry about nature; she knows what she's doing. The universe knows what it's doing and only requires one reason to make paradoxes impossible, not fifty thousand reasons and everything anyone can think of. Every time you make something impossible, in order to avoid a paradox, you remove from engineering's grasp what is ultimately achievable.

Let's play a little game. I can't think of a more intellectually challenging game. Can you explain why a paradox is impossible in a way that maximized what is ultimately possible? Somewhere between, "sorry, nothing is possible" and fifty zillion rules of thumb, you will find an elegant and abstract naturally occurring limitation. But then that is the edge of the envelope and you are ultimately pushing it. Do you follow what I'm saying?

Thank you for finally acknowledging what I'm saying. That is something that I had considered; how is the information content of the spaceship entering hyperspace and then returning, handled?

But let me ask you something. Why does the universe really care if information some how got propagated faster than light? So what? FTL propulsion can't force the universe back into an earlier point in time; that's not the mechanism. The mechanism just moves the information content to a storage place, a hyperspace particle, one that can move with a velocity v < c', where c' >> c.

The reason information content cannot propagate faster than the speed of light is because there isn't anything that can transmit information FTL. If there were, if hyperspace existed, then what paradox would be created?

Actually, they reappear several miles away, but nobody was there to notice it. Below a certain kinetic energy, the electrons do not interact with the chromo-tachyon doped material. What other kinds of experiments might we run?

Lawrence B. Crowell wrote on Jan. 3, 2010 @ 13:51 GMT
Yes nature does care how information is communicated. In a basic course on relativity one of the problems you work in an assignment is to show that there are timelike world lines, null world lines and spacelike worldlines, and these can't be transformed into each other by spacetime transformations. So there does not exist a transformation which can map a timelike path into a null or spacelike path. Spacelike world lines are easily shown to result in a time ordering ambiguity, where cause and effect can be time ordered either way. Spacelike paths are thus regarded as unphysical. Now this is a result for flat spacetime, which is flat globally. You then switch to local analysis, where flat spacetime is something which holds approximately on a very small patch in a curved spacetime. In this case you do find there are strange curved spacetimes with closed timelike curves and multiply connected regions which propagate information on a spacelike interval. So there is a disconnect between local and global principles. What seems to rescue the situation is quantum mechanics. For these strange spacetimes violate the averaged weak energy condition T^{00} >= 0, and the quantum field source for the spacetime field then has no lower bound, or is no regulated properly. As such the quantum field can fall down an endless ladder of states and emit an infinite amount of energy. That energy emitted can cause the spacetime to fluctuate violently as well to probably destroy the solution.

Remember that the Einstein field equation is a general form of the Newtonian field equation of gravity, or the Poisson equation

∂^i∂_iΦ = 4πGρ,

where Φ is a gravitational potential field and ρ is a mass density field. Interestingly if the density ρ is negative the field is repulsive (anti-gravity), where the corresponding violation of the energy condition in the Einstein field equations predicts that geodesics diverge away or defocus in a spacetime sense. Gravity normally operates to focus geodesics together. Negative energy conditions introduce such enormous pathologies in physics, particularly quantum mechanics, that these types of solutions are not regarded as physical. As yet there is no general cosmic censorship or chronology theorem, where these as yet are still hypotheses or conjectures, but what we can understand so far pretty clearly suggests that such a theorem does exist. If it does exist then the causality requirements of a globally flat spacetime hold for any curved manifold as well, which means global and local causal principles are equivalent.

There may be a way to save the quantum field's "no lower limit" situation. If c = 1/sqrt (permittivity * permeability), then a higher speed of light would results in an energy reduction of FTL light. In other words, FTL light transmits less energy then electromagnetic light.

But don't worry, I can still get a Big Bang to occur in hyperspace.

Dear Lawrence,

You said: "...As such the quantum field can fall down an endless ladder of states and emit an infinite amount of energy. "

This problem can be ameliorated if you raise the speed of light, for a hyperspace region, to c' >> c. Since c^2 = 1/(permittivity * permeability), and the Poynting vector, S = E X B, is an energy flux, that energy flux can be rewritten as S = (permittivity * permeability)(D X H). If permittivity * permeability get arbitrarily small, you will curtail whatever endless ladder of energy states you might have. It doesn't exactly conserve energy, but it does introduce some stability to the multi-verse/hyper-space. In addition, this will also make it very difficult to transmit information FTL via an E&M field because such a field propagates with very little, if any, electromagnetic energy.

Certainly it is one way to implement the black box of FTL propulsion. The Alcubierre drive is energetically unfeasible. Moving a tiny universe, the FTL spaceship, around inside of hyperspace is really the only plausible way to accomplish an FTL propulsion system using a modest amount of energy. I can't think of another to accomplish FTL propulsion. Charging up the spaceship with tachyons is just a variation of the same idea.

You had mentioned that strange space-times lead to violations of the weak energy condition resulting in a bottomless pit of negative energy. I was offering a solution to this problem by pinching of the amount of energy that can be transmitted using electro-magnetic fields. If the speed of light in hyperspace is high enough, then this "endless ladder of states that can emit an infinite amount of energy" can be brought under control. Am I communicating this idea clearly?

Hi Ray,

I am assuming that the Higgs field (the mass giving field) is part of the space-time brane/universe/structure. I want to use tachyons as that which excites space(-time) through the range of faster space-times/hyperspaces. For example, let's take a unit volume of space-time; we'll call it c1-space. Add a tachyon, and it becomes a c2-space-time with a velocity of light c_2 = 2c. I suspect most of these hyper-spaces are unstable. But I suspect there is a stable excited space-time/hyperspace for some value of c_i; maybe i=50,000 as a guess. The suggestion is that the tachyon carries something that is similar to energy, but is not energy. Yes, I am borrowing the electron excitation by a photon mechanism.

In answer to your question, each space-time has it's own Higgs field. Will they ever detect a Higgs particle? I doubt it. I don't believe my theory is conducive to a Higgs particle.

I am not sure how my ideas and Higgs interact, but I suspect the 'Higgs' is a Spacetime 'lattice defect' - in other words - it is the projection of an unstable tachyon from hyperspace onto spacetime. If these particles of hyperspace origin can influence spacetime, then there may be hope for your spacetime spaceship to project itself into hyperspace. I still think there are multiple potential problems for this technology, and you may have just scratched the surface of problems, but you should give it your best shot regardless of the criticism. Time, efforts and experiments will reinforce which laws of nature can be bent or broken vs. which truly are LAWS.

I am using the tachyons as part of a mechanism to convert a unit volume of space-time into a unit volume of hyperspace. I anticipate some interesting effects.

Whether I am on the right track or doing imaginary physics, there is still lots of opportunity to understand the physics more deeply. Furthermore, the drifting of physics away from any kind of common sense is an indication of how much we don't understand it. I discovered an interesting process for exploring physics ideas many months ago. Over and over, I would come up with the fantastic and magical understanding of physics; but then, my doubts would start to tear it apart, revealing new insight. The broken pieces would sit around for awhile until another wave of "magical thinking" came along. It's a cyclical process for me. As evidence that this approach is productive, I've been able to force a distinction between (1) observing the effect before the cause, and (2) assuming the existence of a mechanism that makes the whole universe rewind. Number (1) has to occur for FTL phenomena, but you can't do anything about it. However, (2) has been shown to be impossible.

Dear Jason,

My tachyons are wierd. The concept of 'scalar fermions' is illogical. These particles have properly defined intrinsic spin in 8-dimensions, but not in the 4-dimensions of spacetime. I don't know what that translates to, but I'm currently suspecting Higgses.

Have Fun!

Better yet! It's a scalar fermion in 8D. Can it be a particle, with spin, that exists simultaneously in two 4D spaces? In other words, let's pretend it is a particle that exists in space-time and in hyperspace, simultaneously. If something in hyperspace interacts with it, I can see the result of the interaction to it in space-time. Can it be used to interface between two different 4D space-times?

Tachyons really do not help you. They can’t exist as free particles which carry information around. The Regge poles for particles or strings is

J le α’M^2 + 1,le = less than or equal

And the lowest element at J = 0 gives an imaginary mass M = i/sqrt{α’}. Anything with an imaginary mass or energy simply can’t be physically real. This is the tachyon state, which are eliminated by various means. I think they form condensates in black hole quantum singularities or are removed to ∞ by a topology change in an inflationary process which maps a 3-sphere internal to a virtual wormhole to R^3. There is a stereographic type of projection which shoves them off to “infinity.” They do not contribute to realistic physics and become constraints on the number of degrees of freedom in the system.

So a tachyon contributes an imaginary quantity of mass/energy. At best, all I can do is combine it with something else that has an imaginary mass/energy to yield a -mass or -energy.

Part of my theory has to do with treating space-time itself as an object that can be changed/transmuted into another kind of space-time. I don't know if anybody has tried that problem. If a unit volume of space-time could somehow be considered to be a neg-mass/neg-energy, then my idea to convert one kind of space-time into another using a tachyon might make sense.

OK, so adding a tachyon to space-time to make it a different space-time has the complication that we've been discussing. Please refresh my memory. I thought that the Higgs field was the lowest energy state; everything above that is considered a tachyon field. This of course raises the question, does the Higgs field exists everywhere in space-time, in anti-DeSitter space? Can the Higgs field be considered either the same as, or a component of anti-Desitter space/space time?

What I'm trying to do is figure out how to convert/transmute a volume of space-time into a volume of some other kind of space-time.

The Higgs vacuum exists everywhere, as the does the vacuum state of every other field.

A quantum fluctuation that is sufficiently large, or polarized near the singulatiry of a black hole, can pinch off a bit of spacetime and the vacuum energy around it. This pinched off piece can inflate into another cosmology. This is descriptively an aspect of the so called multiverse. There exists a vast number of such possible cosmologies. There are according to Andrei Linde and Vitaly Vanchurin How many universes are in the multiverse? there may be 10^{10^{77}} cosmologies with different geometrical structures.

This will not result in an FTL system. For one thing these cosmologies exist in a 26 dimensional bosonic string, or equivalently a 10 dimensional supersymmetric, Lorentzian spacetime. The speed of light as a conversion factor between spacial distance and time intervals is fixed throughout. Further, there are horizons which obstruct the ability to pinch off into some new cosmologies, enter it and then return. So returning is problematic, for you would not return but get lost in those vast numbers of cosmologies in superspace. You would be truly lost in space.

Tachyonic Higgs field (T-Higgs field) exists around a seed piece of hyper-space material. This field can be construed as a hyper-space space-time with c' >> c.

Higgs Field Exciter (HFE) is a tachyon generator that is used to grow the T-Higgs field. Since the T-Higgs field cannot displace the standard-Higgs field (the Higgs vacuum) around atomically constructed material, the T-Higgs field will flow around physical matter, but not permeate it. The T-Higgs field seeks to minimize its surface area; consequently, it will form a thin coat over the surface of the space-ship.

FTL propulsion engine- when kinetic energy is properly mixed with the T-field, the thrust is directed into hyperspace. Action/reaction forces will cause the T-field mixer to be accelerated in the opposite direction. If the space-ship is completely isolated from standard space-time, other than its own, it becomes a Higgs field core within a hyper-space macro-particle. Action-reaction forces will result in a velocity v of the spaceship; v represents the velocity the spaceship would reach without the FTL propulsion system. With the FTL propulsion system, the spaceship will reach a velocity v' = v (c'/c).

The half life of an excited T-Higgs field is about 3 minutes. If the spaceship is traveling at some velocity v' > c, the faster than light condition with respect to standard space-time, a T-Higgs field failure will not be catastrophic. T-Higgs field failure or diengagement will return the spaceship to standard space-time with a velocity v = v' (c/c').

Manipulating the Higgs field is the closest thing I have to manipulating space (-time) itself without warping space. Warping space takes unavailable quantities of energy. Here is my recipe:

1. Assume the existence of a hyperspace.

2. Make the Higgs field the manipulatable part of space.

3. Acquire a small sample of hyperspace material. Around that hyperspace material will be a small amount of hyperspace (tachyonic-Higgs field).

4. Bombard the hyperspace material with tachyons. If I can think of something better to call this field, I'll call it that.

5. The standard Higgs vacuum around the hyperspace material will begin to convert into a tachyonic-Higgs field (T-Higgs field).

6. When this T-Higgs field completely encapsulates a small region of space-time, containing the spaceship, and stabilizes, it will be possible to remove the spaceship from space-time.

Other then skepticism, did everyone understand what I'm doing?

Please forgive my enthusiasm/stubbornness when it comes to FTL propulsion. It has become kind of a fun puzzle/obsession to me. Even if we can't build it, don't have the materials or access to the laws of physics, I would really like to figure out what would have to exist for FTL propulsion to exist.

The Higgs field provides the mass giving mechanism for W+ and W-, weak force, particles. I decided to lump all mass giving mechanisms into the Higgs field. Since E = mc^2, energy, c, and mass are all tied into the same object that we observe as space-time, I am assuming that the Higgs field implements space-time. Frame dragging suggests to me that the Higgs field can be treated like a fluid.

OK, I admit it! I am applying some imagination and science fiction to the engineering involved in constructing a hyper-drive. Every time you balk at what I'm doing, like the very brief tachyon particle lifetime, I have to come up with something else.

I couldn't find the conversation where we discussed the resemblance of stacked Schwartchild spheres; the spheres had energy levels. The lowest energy level gave us space-time. The higher levels were tachyonic and discarded. You and Ray suggested that we could ignore them. I decided we could still use the idea. But then that leaves us with the conundrum of how do you make a volume of space-time transition into a volume of hyperspace? If a tachyon field doesn't work, I will find something else to make it work.

If I can surround and completely encapsulate the outside of the spaceship with this generated/transmuted layer of hyperspace, I expect it to allow my spaceship to masqeurade as a hyperspace object, subject to the laws of motion of hyperspace.

Sorry, I got a little carried away back there. If you don't like where this conversation is going, I understand.

It is true that you keep throwing up new conjectures which can be shot down. In dealing with creationists I say it is like shooting ducks in a shooting gallery; they are easy to shoot down, but they keep popping back up. At a certain point hitting tennis balls back from a machine which keeps serving them gets a bit old.

Eckard,

The problem is that you are imposing metaphysical ideas to cast a judgment against a physical theory. This is what causes people to have such problems with quantum mechanics. Progress in the foundations of physics tends to modify our sense of what is meant by causality, trajectories, time and so forth. These modifications are usually the removal of some obstruction or “excess baggage” that prevents progress. The notion of time you insist upon amounts to the re-imposition of an obstruction to physical understanding.

If you're refering to the log(-number) stuff, I was just teasing Eckard. If your referring to FTL phenomena equates to time travel, then your just not using common sense.

Example: You are looking at an FTL spaceship through a telescope that is 30 light seconds away. It jumps to hyperspace and stops right next to you. You get to watch the image that is 30 light seconds away for about 30 seconds before it disappears. You are shocked that you see that image, but also the same spaceship that is right in front of you. You will get strange observations like this, but you won't get wormholes or time traveling.

I figure that the reason you cling to c so tightly is because, if you introduce a second velocity of light, c', 26 bosonic dimensions will come crashing down, destroying 50 years of hard work.

A main reason for me to trust in c is its relation to electric and magnetic fields: 1/c^2=epsilon_0 times my_0. Moreover, didn't we have to expect an application if Nimtz's claim was correct? Well, sometimes it is difficult to benefit from correct insight, as in case of nuclear fusion, which was proven possible with the H-bomb.

I wonder how self-confident you are speaking of the universe and its properties. Isn't our tangible knowledge of far remote objects still rather incomplete? Are you sure that the "whole" universe rewinds itself? And if so, may we benefit from such idea? Consider ms stupid: I am not even sure that singularities are more than mathematical ideals that do not have physical correlates. Aren't they rather just clever approximations of reality? I like the function sinc(x) because it is not singular at x=0.

My skepticism is based on getting aware of seemingly minute nuances in meaning.

A gauge is scaled with numbers attributed to points on the real line. However, the meaning is quite a little bit different. Every number does not belong to a point on the line but to the distance between this point and the reference point zero.

I do not deny that future time is reasonable on the level of abstraction. However, it is undeniable that future processes are not yet reality.

I do not belittle that negative and imaginary numbers, harmonic functions, and complex calculus were and still are utmost important in science and technology. However, does this make e.g. a sine function that is thought to extends from minus infinity to plus infinity something we can find in reality?

I do not see old rules outdated: Anything flows. Trees do not grow into the space. Life is finite. Nobody can evade aging. Only the name geo is inappropriate in Euclid's. In reality, the whole is alway larger than its parts.

My comment: The map is not the territory. Perhaps, a considerable part of modern physics is just unjustified speculation. Let's clarify whether my concrete hints concerning apparent symmetry are correct.

There was a time in my life (at the U. of Texas - HOOK 'EM HORNS!) when professors 'forced' physics on me so much that I hated it. I tolerated it to a point because I wanted an advanced degree. Finally, I swore off physics and quit grad school. But when other people weren't forcing their expectations on me, I learned that I do love physics as a hobby. I started to make progress on my Quantum Statistical Grand Unified Theory, and decided it was time to go back to graduate school. The second time in grad school (at Florida State U.), I wanted to learn everything and stayed near the top of every class - no one was forcing me, I loved it!

Sometimes, the best thing you can do is take a break from beating your head against the same brick wall. I still like the expression "Never say never", but it will be tricky to develop an FTL drive because GR and the 2nd Law of Thermo seem defiant against it. If I understood multiple dimensions better, I would use that knowledge to help inspire you. Perhaps we both need to wait for another breakthrough.

Lawrence,

You said, "If you want to understand these matter, such as why FTL is not likely, you have to do the serious work." Why would I want to learn why FTL is unlikely? What is the benefit to that? If it's unlikely, but not impossible, why wouldn't it be worth someone's time to figure out how it might actually work or be possible? But if the physics community's attitude towards FTL is: it's impossible, let's figure out why it's impossible, you'll never figure it out. In fact, American's are not supposed to think like that.

Ray,

You said, "..but it will be tricky to develop an FTL drive because GR and the 2nd Law of Thermo seem defiant against it. " Thermo prevents time travel; since time travel DOES NOT EQUAL faster than light phenomena, than it's ok.

How can FTL propulsion be possible without damaging GR? You won't understand, but it's like a Russian doll. You have to nest a set of space-times with the higher velocity space-times inside of the outer standard space-time.

If you nest space-times, the outer most 4piR^2 surface represents our observable space-time. The radius R is actually a 1/c term; so the larger c gets, the smaller the radius of the space-time (hyper-space) surface under consideration. This mathematical model of nested space-times just gives a way to insert FTL capability into every point in space. Inside of the event horizon of a black hole, there would be another surface or just hyperspace, where hyperspace represents all space with a velocity of light c' > c.

Coupling between surfaces of each space-time is an endeavor I haven't gotten to yet. This model would make it possible to generate a hyper-space field around your spaceship, making it possible to be removed from our space-time/universe.

I have no real evidence for this, but it would provide a nice theoretical framework for an FTL propulsion physics theory. I'm sure Lawrence will hate it.

If you can even make such a thing, it would be a weakly-coupled quantum event- perhaps based on an exotic particle or field such as the Higgs or WIMP-Graviton - anything else would occur regularly enough to destroy/reshape the Universe we know into a spacetime/hyperspace hybrid Universe. Effectively, you want a 'Bermuda Triangle' event that you can control. But isn't that an oximoron? How can we control a quantum event that has statistical outcomes by its very nature?

Thank you for recognising some of the real problems. Coupling. What are we going to couple two space-times with? I know that electromagnism, charges and virtual particles have to be confined to this space-time. Since the speed of light is built into mass, E=mc2, then all of those momentums and mechanics for motion are confined to this space-time, or should I say, Higgs field. Gravity, I'm not sure about. Whatever couples between space-time/Higgs fields probably has something to say about gravity.

Correct me if I'm wrong, but I think that compression of space-time/Higgs field, if you could squeeze it, is interrelated with high mass-energy. So a black hole would squeeze/compress the Higgs field until an event horizon forms. But could you move it around without squeezing it?

In any event, the strategy is to cause the space around the spaceship to change/transmute into hyperspace space in such a way as to completely surround the spaceship. If you do that, the hyperspace aorund the spaceship becomes a hyperspace object, subject to the laws of motion for hyperspace.

You won't have to cross the Cauchy horizon. In a way, your spaceship is being smuggled aboard a hyperspace particle/object. Your spaceship will be inside of a hyperspace space which completely surrounds your spaceship. When this occurs, a new object appears in hyperspace. The laws of hyperspace will only know that your hyperspace mass is m' = m(c/c')^2. The hyperspace particle/object will have some mass also, but I'm neglecting for the now.

While inside of this hyperspace object, E&M waves will be completely blocked. You will have no contact with the physical universe because you will be "an island of space-time in an ocean of hyperspace". If you ever wondered how shields and forcefields work, guess what!

As the hyperspace object, with the spaceship smuggled aboard, travels, it will obey time and relativistic effects according to the ratio of v/c'; which of course lets you calculate gamma, etc...

Of course, the observers who watch the spaceship suddenly vanish from view, will scratch their heads and call it a hallucination.

You mean the speed of light barrier? By generating a hyperspace field around my spaceship, and effectively being smuggled into hyperspace, here is what happens. Let's pretend that hyperspace has a speed of light of c' = 1000c. The spaceship can reach v = 0.01c without any FTL propulsion engine. But with an FTL propulsion engine, with a proper design for transmitting kinetic energy out of the spaceship and into a propulsion field going the other way (action-reaction forces), the spaceship can acheive a velocity v = 0.01c' = 0.01*1000c = 10c. During the acceleration phase, the spaceship with pass the speed of light barrier c, without any fanfare. But the spaceship cannot cross the c' barrier without transioning to another hyperspace with an even faster speed of light c'' > c'.

I am assuming that energy is conserved. The use of an encapsulation field, a hyperspace field, simply scales the velocity, acceleration and distances I can travel. I'll explain more later, I have to get back to work. But it's a loophole I found in the laws of physics. That is why I need the nested space-times.

I found: Dr Guenter Nimtz, of Cologne University, an expert in the field, agrees. He believes that information can be sent faster than light, but that this will not breach the principle of causality because the time taken to interpret the signal would fritter away all the savings.

"The most likely application for this is not in time travel but in speeding up the way signals move through computer circuits," he said.

Wang's experiment is the latest and possibly the most important evidence that the physical world may not operate according to any of the accepted conventions. In this new world, sub-atomic particles can apparently exist in two places at the same time - making no distinction between space and time.

Separate experiments carried out by Chiao illustrate this. He showed that in certain circumstances photons - the particles of which light is made - could apparently jump between two points separated by a barrier in what appears to be zero time. The process, known as tunnelling, has been used to make some of the most sensitive electron microscopes.

The implications of Wang's experiments will arouse fierce debate. Many will question whether his work can be interpreted as proving that light can exceed its normal speed - suggesting that another mechanism may be at work.

Neil Turok, professor of mathematical physics at Cambridge University, said he awaited the details with interest, but added: "I doubt this will change our view of the fundamental laws of physics."

Wang emphasises that his experiments are relevant only to light and may not apply to other physical entities. But scientists are beginning to accept that man may eventually exploit some of these characteristics for inter-stellar space travel.

If necessary, I may give references that prove Nimtz wrong.

Incidentally in contrast to sound barrier, I consider light barrier independent of a medium and therefore absolute.

I quoted the Sunday Times because Nimtz was definitely wrong when he claimed having observed transmission of signals with a speed in excess of the velocity of light in free space, and therefore I consider it unlikely that FTL and time travel are nonetheless correct. See e.g. the attached file.

As a joke, I addressed to Peter Jackson a suggested by me thought experiment that could demonstrate an unlimited, in principle, velocity, let's say 1000 times c.

The twist by Nimtz to attribute savings on one hand combined with complete loss on the other hand reminds me of the mathematicians who do not shy back from any twist to save by tortuous definitions Cantor's nonsensical but nonetheless highly welcome naive set theory. Such creation of mere belief did not and will not lead to useful applications. Fortunately, the chance that the majority of physicists will behave as did the mathematicians one hundred years ago and follow, with Weyl's words, a piper like the children of Hameln seems to be small.

Eckard,

Space-time, and the corresponding charge and electromagnetism, simply can't move FTL in any practical or useful way. To get FTL propulsion, you really have to work with a faster space-time (hyper-space). If we happen to discover one, we're in luck; if not, well have to settle for new Star Trek movies with increasingly decrepit appearances of Leonard Nimoy.

If we do discover a second space-time with FTL capability, transmitting information content by E&M waves might be problematic. For a c' = 1000c, permitivity and permeability are both reduced in energetic flux by a factor of (c'/c)^2. Since the poynting vector S = E X B = (permeabilty*permitivity)D X H = (1/c)^2 D X H, (1/c')^2 D X H is about a million times smaller. I really don't want to transmit signals FTL, I want to move spaceships with cargo, FTL.

Dr Cosmic Ray (Captain Cosmic Ray),

No need to worry. If we find this second space-time/hyper-space, then you can worry.

Lawrence,

Maybe Obamma will let you borrow his green piece of paper printer. If not, don't worry, will all be knee deep in it sooner or later.

Dear Jason and Steve,

You forgot to pack the magnetic monople? Cosmic Rays are very dangerous - they give you cancer without the superpowers of the Fantastic Four. Any spacecraft would need a substantial amount of materials or fields surrounding it. We don't expect Electromagneic Fields to be stable in Hyperspace, so we might have to use Hyperflavor Fields.

Dear Steve,

At one point, I was going to offer to keep some of your plants in Florida so they wouldn't freeze, but then 'Global Warming' hit Florida and froze us to death. The last four days, our low was between 17 and 19 degrees Farenheit or minus 8 degrees Celsius. My garden doesn't look very good right now.

Dear Lawrence,

I understand about the green pieces of paper - a necessary evil. My work is time-consuming, but not mentally-taxing, so I have time to play with ideas.

Have Fun!

Ray,

If you think highjacking physics, copying its basic format, and coming up with something creative is easy work, believe me, it's not. If we're lucky, the way to accomplish FTL might be right. If not, it's still fun to work on.

I didn't want to violate conservation of energy, and I wanted to be logically consistent. By creating hyper-space fields around a spaceship, it lets me leverage energy/laws of motion to travel faster and farther. But how do you interface one or more of the four forces with a mechanism that controls the speed of light for a volume of space? I do have some ideas.

Why would nature pick the values c and h, as opposed to some other values? I'm guessing that stability occurs at these values. Let us pre-suppose there are other sets of values for basic physics constants that are stable. Two or 3 other stable spacetimes would be ideal. If they have matter/energy in them, it certainly doesn't interact with anything in our universe, that we've noticed.

Magnetic monopoles? I know what they are. It just seems like an oxymoron. Magnetic dipoles are induced when charged particles spin. The fact that forces exist at all is a stubbornly difficult clue to the nature of space itself. Just a silly thought, but can spinning charges induce a form of frame dragging? I just get this picture if an electron creating a whirlpool in the Higgs field. Is that picture consistent with physics?

Hyperflavor? I might want to copy the idea of mesons/quarks to interface with the forces that control the physics constants for a volume of space.

And if you feel it's necessary to utilize the powers of the Fantastic Four to accomplish any of this, then by all means, do it!

Why do you not look for possible mistakes in what is presently considered the foundations of physics or at least in what experts like Nimtz notoriously are claiming? Admittedly, this would not be a good piece of advice for those who depend on money from authorities who are prone to be best cheated with the most exotic promises.

I tried to serve science the other was round. I noticed a strange phenomenon in physics of plasma, and I combined as many different methods of experimental investigation as I was able to perform: high speed videos from orthogonal sides at a time, simultaneous records of electrical quantities and sound, and others.

I presented my results step by step on conferences: Berlin, Strasbourg, Paris, Orlando, Lanaken, Sevilla, Milano, Orlando, Essen, Graz, Pine Mountain, San Francisco, Bern. When I demonstrated the phenomena to experts they were surprised. When Prof. Jüttner visited me, he not only confirmed my observations but agreed to apply for a joint project, which was rejected. Some referees and editors did not like what was obvious to us. It was at odds with theories. Only a comment of mine was printed, cf. the attachment.

I do not dislike theories. On the contrary. I like the beauty of mathematics. However, I vote for realism. This means troublesome work and sound distrust against mere speculations on possibly questionable fundamentals. Why and how do you expect finding your space-time-hyper?

By the way, several of my high-speed videos showed flying spatter that looked very similar to new born stars. The dynamic diversity of my data in combination with experimentally proved theories was perhaps a better basis for a puzzle of interpretation than the quasi static pictures and spectra of stars in combination with easy readiness to even ignore causality. Nonetheless, I was aware of the possibility I misinterpreted some details, something Nimtz seems not to be able to.

If Reed Richards had an anti-matter portal, it would have blown him to bits. That's not the kind of FTL I had in mind.

By the way, I know Lawrence has mentioned that if c and h could scale, we'd never notice. Yes, I complained that conservation of energy would notice. But setting that aside, why wouldn't/couldn't a second space-time exist with a scaled c and h? Maybe some other constant can force it to a lower energy state.

Jason, isn't the incredibly simple insight much more exciting that there is always an upper limit to elapsed time or even anticipated elapsed time? Maybe, those who rejected our project were correct. Even Prof. Jüttner was not able to improve much what I already found out. A particular obstacle was that the phenomenon of concern occurs by chance.

What about our videos, they were recorded on several analogous magnetic tapes. When I got retired in 2007, I gave them to our welding department. Due to limitation of my computer, I had digitalized just a few selected details.

The plasma phenomenon I was after is not very important. However, even my boss confirmed that he felt unable to comment on my suggestion not to blindly integrate over time from minus infinity to plus infinity as he did and still does in front of his students on a regular basis. The matter, he said, is too foundational. I appreciate the possibility to address it here at FQXi. I am claiming having found mounting evidence for correctness and important maybe key implications.

More generally speaking I am suggesting that it might be worthwhile to clarify to what extent mathematics is appropriate in physics.

Non-causality is known to me as an mathematical artifact due to apparent symmetry. Observable phenomena do never violate causality. Just models might be wrong if we admit that it is reasonable to distrust any mysticism.

The phenomenon I refer to belongs to an unstable erratically appearing arc mode that seems to contradict LTE. It has no direct connection to my work in signal processing and the ultimate value of time, the now. Physics of arc welding is a very interesting object of research with a lot of phenomena relating to strong magnetic fields, liquid metal, many kinds of particles, and partially very high temperature.

Non causality means that the mathematics is unreliable. The problem with mathematics is that it becomes (1) too difficult to understand and (2) too far removed from common sense. Just because the universe follows an accounting system doesn't mean it's made of math. In my debates with others over the possibility of FTL propulsion, it took six months to get them to understand that FTL does not equal "time machines". I wonder how many decades or centuries it's going to take to apply some common sense to what is possible and what is not possible. If symmetry arguments are coming up with non-causal events, then maybe symmetry only works when you compare apples & apples; maybe symmetry arguments are being used incorrectly.

Just curious, if the speed of light, c, is constant, can we or do we perform experiments on a regular basis that try to measure the velocity of light, as accurately as possible, under varying circumstances? For example, do we measure it regularly at sea level, below sea level, in the mountains, in space, and at various velocities? To the best of my knowledge, it is not the most finely tuned constant. Are we able to detect small changes in the value of c, 1ppb or 1ppt? If we could regularly check this value, it would be helpful to attempt to match small changes to a particular set of circumstances. For example, what if c changes by 1ppt when in free fall as opposed to sitting in a lab? While tiny changes to the speed of light might not have any effect for our chemistry or our present understanding of physics, it could provide a basis for a new deeper level of physics.

Physics has to learn: No matter whether a Dirichlet or a Neumann mirror. The original is essentially different from reflected picture. Merely the picture and the mirrored picture may be considered like apples and apples.

Therefore I expect still failed search for SUSY rather than successful travel FTL in 2180. I would not exclude a priori that c is subject to changes as I also cannot exclude that the world is ruled by Buddha, the god of Jews, Christs, Muslims or the like. However, already obviously wrong claims by Nimtz, Cantor, and the like make me utterly skeptical.

Let's be as honest and humble as was Hermann Weyl when he admitted: In the moment there is no explanation in sight (for apparent PCT symmetry).

To (2) you did perhaps correctly criticize inappropriate use of mathematics.

Eckard,

Let me just say that mathematics is a very useful tool. I am sympathetic to those who want to push the limits of the mathematical model to try to fill in aspects of the laws of physics that are beyond our reach. But using mathematics to buttress why we think something is impossible, particularly when some symmetry is crossed, places an unnecessary handicap on the on the pursuit of new physics. Particularly, the mathematics of GR, when velocities faster than light are considered, in puts the mathematics into the time domain. Since the time domain indicates time travel, which is impossible, the logical assumption is that FTL travel is impossible because it leads to time travel. But a closer examination suggests that we might have accidentally glossed over something that may yet be possible.

My point is that we shouldn't just blindly believe the mathematics. Occasionally we should look more closely to see if the mathematics makes sense. We should recognize that mathematics can leave open multiple interpretations, some of which might not make sense.

I think they call it: wisdom.

Jason, the prefix in of the word influence points to what is called the direction of time. This directionality got lost when laws were abstracted as differential equations instead of originally integral ones. Accordingly some mathematics is misleading in so far as it offers unrealistic solutions too.

We should not merely occasionally but always very carefully look what mathematical solution is realistic.

Sometimes even unrealistic solutions are useful to some extent, e.g. so called ideal non-causal filters.

What about FTL, one could speculate that paramagnetism could allow c to be quite a little bit than c of vacuum, provided epsilon is not larger than epsilon_0.

What about "new physics", a lot of it it reminds me of new economy before y2k. You should not try and cross the mirror in order to feel your face.

I agree with you that FTL does not violate causality or is equivalent to time travel. Consider the following simple scenario: The year is 2180. A outpost on Mars has been constructed and is inhabited. For many years, the base's occupants and mission control on Earth have put up with the annoying fact that it takes 11 minutes for messages to be sent or received due to the limitations of using radio waves traveling at the speed of the light. But good news is at hand, engineers have just uncovered long lost documents from a mad scientist named Jason from the 21st century who discovered that FTL travel was indeed physically possible. Following his plans they are able to create a device that will record a message and deliver it thru hyperspace to the inhabitant's of Mars. On their 1st attempt they are able to send a message through hyperspace with an effective velocity of 2c. The engineers are ecstatic since the device worked flawlessly. The Mars inhabitants are not as thrilled, since it still takes 5.5 minutes to receive their messages from home. The engineers go back the drawing board and come up with a "super-charged" version of their previous device that has an effective velocity of 10c. The transplanted Martians are somewhat impressed, their messages from home only take 1.1 minutes. The engineers give it one more try and this come up with a "turbo super-charged" version of the device with an effective velocity of 1000c. Finally the Mars inhabitants are truly impressed, they can have conversations with their loved ones as if they were in the same room. The point is that even though information is being transmitted FTL, chronology is still preserved. If this doesn't fit in with accepted theories of QM and GR, then maybe it should be seen as a learning opportunity.

You are exactly correct! Your example reminds me of when I was stationed in Kuwait between the first and second Gulf war. I was fortunate enough to be able to call home using a computer/internet telephony application. There was a delay of about a 1.5 seconds which made conversation 'very nearly' real time.

In truth, I'm not altogether sure what happens to E&M waves when the speed of light gets large; I believe that start to lose propagation energy because c = sqrt (permittivity*permeability). I've been meaning to try to calculate the "magnetic gravity"; I've been kind of busy lately. When I get a chance, I want to try the same calculation for the gravitational constant G and the equivalent magnetic gravity. I want to see if it's possible to write a similar equation c^2=1/(G*G_H) where G_H is the magnetic gravity. I'm not sure about the units. I don't even know if magnetic gravity has been observed.

The whole point of my example was to show that information encoded on a device and sent FTL does not mean that it is sent through time into the past. With each improvement, the engineers only decreased the transit time of the information sent, albeit through hyperspace. No time travel occurred. The past only exits in the information we receive via EM waves due to the limitations of the speed of light over vast distances.

I do agree with you. The anecdote above was in your defense to those who believe that FTL equals time travel. Before you can build a starship, you have show that you can send anything FTL i.e. start as simple as possible. How would you send a proton or electron through hyperspace? Shouldn't this be an easier task? The reason foundational questions are so tough is that it takes many years to master even one subject let alone many. The person who takes on this task needs to set aside much of what they have learned in order to think outside the box and not automatically dismiss fantastic possibilities. Until someone can tell me why FTL equals time travel rather than FTL equals a decrease in effective travel time, I will not be convinced that they are correct. Since this in opposition to current doctrine, doesn't it suggest that this is a opportunity for new understanding?

Bingo!!! I've been thinking a lot about this. Let's take a volume of space; remove everything inside that can be removed (stuff, air, particles, etc...). All that remains is the ZPE oscillators that can't be removed. I can tell you that whatever happens inside of that volume, that box, the laws of physics still operate normally.

Now, frame dragging left me with the impression that space can be distorted to some degree for particular situations. If it can be distorted or compressed, that empty space can be treated as a "something" as opposed to a "nothing". It reminds me of rubber or nylon. By the way, gravity, to me, seems a lot like compression of space. Let me know if you disagree with my interpretation.

If empty space is a "something", than we should really give it a name other than empty space. For want of a better word/terminology, I am calling it a Higgs field or perhaps even a Higgs fluid.

Next step: I want to change the properties of this volume of Higgs field/fluid. If I do that, then the problem starts to look something like chemistry. I want to add some of ??? to a volume of Higgs field/fluid.

I have recently become aware of a 2nd interpretation of GR while reading Kip Thorne's Black Holes & Time Warps. Like most people, I was familiar with what he refers to the curved space-time paradigm, i.e. how Einstein's field equation describes how matter generates the curvature of space-time, how curved space-time tells matter how to move, ect. I was amazed to find that an equally valid interpretation was what he referred to as the flat space-time paradigm. This paradigm is defined as laws describing how matter in flat space-time generates a gravitational field, how that gravitational field controls motions of matter and energy and how the gravitational field controls the shrinkage of perfect rulers and the dilation of the rate at which perfect clocks tick. This interpretation has been much more intuitive for me, and has lead me to certain insights that I would have realized without it. Thus gravity to me is not a compression of space, but due to the field associated with matter and energy. The greater the field density, the more influence it creates.

Dan,

If you look at Ricci curvature within the Einstein equations, there is a sentence that I will quote:

"In differential geometry, the Ricci curvature tensor, named after Gregorio Ricci-Curbastro, represents the amount by which the volume element of a geodesic ball in a curved Riemannian manifold deviates from that of the standard ball in Euclidean space. "

That came from:

http://en.wikipedia.org/wiki/Ricci_curvature_tensor

I interpreted a "deviation" from that of a standard ball, to mean compression. The kind of compression that you do to a Nerf ball when you squeeze it. Do you think that I've misinterpreted the meaning of that sentence?

I definitely liked the second interpretation that you mentioned, of a flat space time with gravity fields in it. But that "something" that I've been referring to has to do with "that which is curving".

I guess what I picture in my mind is that the perfectly flat space is filled with an invisible and, so far, undetectable medium. That medium is what produces the laws of physics, GR and QM. My feeling is that gravity causes this medium to distort.

By the way, in my opinion, if there is one medium that fills the "perfectly flat" space, then why can't there be a second medium such that the two overlapped mediums are uncoupled or, at least, very weakly coupled as far as E&M is concerned.

To explain dark matter/dark energy, I'd like to try the "second medium" approach.

What say you?

The Einstein field equation is

R_{ab} – (1/2)Rg_{ab} = (8πG/c^4)T_{ab} - Λg_{ab},

where R_{ab} is the Ricci curvature tensor, T_{ab} is the source of the gravity field (mass-energy density etc) and Λ the cosmological constant. The Ricci curvature tensor is derived from the Riemann tensor R_{ab} = g^{cd}R_{acbd}, and the Ricci scalar R = g^{ab}R_{ab}, from the metric tensor g^{cd}. There is an implied summation between upper and lower indices --- called the Einstein summation convention. If we assume that the momentum-energy tensor T_{ab) = 0 (a vacuum spacetime) we can write the Ricci curvature as

R_{ab} = ((1/2)R - Λ)g_{ab},

so the Ricci curvature is proportional to the metric. This is a special type of space, called an Einstein space. Now can there be a source for the cosmological constant? Yes, it might be the quantum vacuum of the energy, or the zero point energy (ZPE). So the cosmological constant might be written as

Λ = (8πG/c^4)((ρ +3p)

for ρ the energy density of the quantum vacuum and p the pressure. Data from WMAP indicate that p = -ρ to within a small percentage of error. This is a critical condition, with equation of state w = -1, at the boundary between positive and negative energy condition. So the medium is the quantum vacuum, or a vacuum state associated with a Ricci curvature,

For the universe the Ricci curvature along the spatial directions on the Hubble frame is zero. It appears that the space is flat. However, one space is connected to another by what might be called a time vector t^a = N^a + Ne^a. for N and N^a the lapse and shift function that connect different spatial surfaces as they evolve together. So this embedding of spatial surfaces does have a curvature. This curvature is what keeps the universe is a state of expansion, and indeed accelerated expansion.

Dear Jason and Dan,

Jason said: "that empty space can be treated as a "something" as opposed to a "nothing"."

This summarizes a long conversation that Leshan and I had on his "What is Ultimately Possible in Physics" essay blog site, and I agree that a 'nothing' or 'hole' quanta would attract spacetime and, therefore behave like a Higgs (defines mass) and/or graviton (attracts mass). The Higgs seems to be the best analogy because a graviton has an intrinsic spin of two, and that doesn't quite seem reasonable for a spacetime hole.

The different ratios of this 3D give very interesting correlations with the thermodynamic ,the mass is evolutive ,furthermore if all turns around the universal center ,thus the motion and thus the spaces between cosmologuical spheres and quantic too is different in all moments .The topology takes all its sense in this reality in a close system .The factors of deceleration ,acceleration expansion ,contraction like a ratio ,d²a/dt²a(da/dt²......4piGp/(3H²o.....what I find relevant too is the increase of mass thus the density .The pression in an adapted Friedman equation seems important thus in a finite system ,PV ...nRT can be correlated with the quantum system and its rotating spheres and the specific number of spheres .There too the fractal of divisiblity of the main sphere takes an universal sense.

The mass don't be diluted in infinity with a(exp-3)The number of particles must be re thought in this evolutive increasing of mass .

The ray of light evolves proportionaly with an exponential of-4 ,the density of photons and the density of rotating spheres and quantum spheres without rotations ...because the gravity polarises and builds with light .

D is important thus with dR(exp3)the constant in a kind of instant but in an evolutive point of vue all is different in its variables .The expansion is logic but specific in the time ,thus tending to an equilibrium ,but for a pragmatic interactions between lifes ,a contraction is necessary and there the gravity is essntial like the critic point or the maximum expansive volume .

Thus the critic density is interesting .The r of curvature of the space time takes all its sense with a balance between forces at the universal scale .The dark matter is mass in waiting ,spheres without rotation ....the density .

However in your case, c is reciprocal to 1/c, and more importantly, you demonstrated that physicists do not use the possibility to check dimensions:

B/H is measured in Vs/Am while D/E is measured in As/Vm. Together results (s/m)^2.

Such mistakes are tolerable. However, if high profile experts calculate as if the positive and negative energy are matters of fact and FTL just a question of the year 2180 or later, than I guess they should have to disprove objections like mine.

Ray,

I agree; let's just call it the Higgs field for right now. That "something" which fills all space and supplies the laws of physics; whatever the laws of physics are, it occuppies all space. Higgs field/space/volume/fluid?

As for the absence of space, a hole? I'm not sure about a hole in the Higgs field. I guess when a diver exhales bubbles, that is sort of like a hole in water. If there is a hole in the Higgs field, there would be a volume of space in which (a) particles cannot exist, (b) laws of motion are undefined, (c)...

On the other hand, a hole might be another kind of space, like a hyperspace.

Eckard,

That was a typo, c^2 = 1/(permitivity*permeability). A faster speed of light is going to result in less energy transfer via E&M.

Dan,

I agree with you. The second interpretation is better. Let geometric space be flat. Then, we'll fill it with a Higgs field that has general relativistic qualities; gravity can be a force again, the way we experience it. If we do it this way, we can define a volume of space; in that volume, we can say there exists a space-time/Higgs field with certian properties. The Higgs field gives us particulate matter (Standard model particles). We can also imagine tweaking or changing the Higgs field into something another kind of space-time. We can also imagine overlaying one Higgs field/space-time over/on top of another space-time/Higgs field with carefully designed properties to minimize coupling of particles from each set. If we do stuff like this, we might be able to tease out the basic structure of space-time/Higgs field in some mechanistically rich form.

Jason,

I am truly astonished that time travel is still taken seriously. I even cringe when I hear of "time travel to the future" as a consequence of relativistic time dilation. It's not that I'm dismissing the effect but rather this interpretation.

Time travel as depicted in science fiction should be defined as the ability to move through cosmic time at will, whether forward toward the cosmic future or backward toward the cosmic past. This is not what is occurring with relativistic time dilation. Even clocks that undergo the "most severe" time dilation, (i.e. traveling very near the speed of light in SR or very near the event horizon of a black hole in GR) are only ticking at a slower rates (into the future). Never does that clock "jump" into the future. No matter at which rate the clock ticks, there is a continuous transition, always toward the future.

As for backward time travel, I agree with some of your earlier posts, that this is a clear violation of the laws of conservation of mass and energy as well as the 2nd law of thermodynamics. Backward time travel proponents suggest that if the light barrier were broken, backward time travel would occur. This is terrible reasoning.

****** Clocks in motion are the only ones affected by the time dilation as a result of that motion.****** Therefore, if a clock were able to break through the light barrier as a result of its motion, its rate of ticking should reverse with respect to the greater cosmos.It is not the cosmos that is getting younger (as in backward time travel), but the observer in that frame. This is a reversal of entropy and is clearly forbidden. Absurd consequences would follow. A observer in such a frame would age in reverse, becoming younger and younger as a result of his motion until he ceased to exist!

This may seem to preclude FTL travel also, but as in the Alcubierre drive, the observer does not cross the light barrier as a result of his own motion. Mass and energy are conserved through cosmic time and entropy always increases.

FTL propulsion is the desired outcome. If approaching the speed of light is energetically too difficult, and passing the speed of light gives bizarre mathematical effects, then do something a little different. Scale the speed of light to a higher value. How do I do this? Generate a field around your spaceship. This field divorces your spaceship from space-time. Second, the field itself becomes a particle in a stable hyperspace, if one exists. Here we get into lots of new speculation about whether a stable hyperspace existss, and also how do you generate such a field. The idea is that the field itself becomes a particle within hyperspace. In that hyperspace, the velocity of light is c' >> c. That is the basic idea. In this manner, clocks always obey relativistic rules; therefore, your velocity might be v = c, but if your spaceship is inside of a field, and c' = 100c (for example), then your velocity can equal the speed of light or faster, but your clock will obey the gamma (v/c'). In this way, you're not really traveling faster than the speed of light, c'. But you are traveling at or faster than c. The clock on the dashboard of your spaceship obeys time dialation effects using c' as the velocity of light. That is what the field does for you.

I've been trying to think of what to call the "thing" that occupies empty space. How does the term Higgs Brane sound? The Higgs field is something that gives mass to W+ W- particles (weak force). But I've come to know the Higgs field as that which gives particles their mass. In other words, the Higgs field really converts energy into particulate matter; or at least it can be interpreted that way. A 'brane' comes from string theory and is short for membrane. I like the idea of a membrane. Also, a membrane is what superstrings move along, which places them as particles in empty space. Thus a Higgs Brane is the space-time that occupies a volume of space, implements the laws of motion in that space, brings forth particulate matter from energy (E=mc2), and is the thing that warps when gravity tugs on it. Branes can also be stacked; at least I plan to stack this Higgs brane with other branes.

Dear Jason,

If you want to call it a Higgs-brane, then I'll also embrace the terminology. I think this is the M2-brane (and/or M3-brane) that Lawrence has been talking about, and the generation-brane (w/ imaginary time) that I have been talking about. I think this Higgs-brane is a badly broken (2+1)-brane that yields Lisi's generational triality, Lawrence's G2 triality, and my 12-dimensional model with buckyball triality/pentality. This should also fit into Leshan's and your ideas as well. These Higgs and tachyons are related.

Hi Ray,

The advantage of describing a Higgs brane is that, in a volume of space, I can provide a name for (1) that which converts energy into particulate matter, (2) lays down laws of motion for matter, (3) gives us electromagnetism, (4) deforms in a way that produces gravity in response to significant amounts of mass-energy, and (5) provides the characteristics for wave amplitudes/Quantum Mechanics.

Then, I can also say that a hyper-space brane exists in the same observable 3D space; 3D space is readily observable, not hyperspace. If you look up the Higgs field in wikipedia: http://en.wikipedia.org/wiki/Higgs_field, there are additional authors whose names are not mentioned. Since they need fame, and I need names, I want to call the first hyper-space brane, the Brout Brane.

The Brout brane, which is the first hyperspace brane, exists in the same 3D geometric space as the Higgs-brane. As a hyper-space brane, its speed of light c_B = 5c. The Brout brane has its own particles and forces; they are, of course poorly coupled with particles and forces on the Higgs brane. For that matter, neutrinos are poorly coupled with particles/forces on the Higgs brane.

Now, this is where it gets complicated. When my spaceship generates a tachyon field around itself, it will eventually stabilize into a thin layer of Brout-brane, called a Brout field. The rest of the Brout brane will say: "oh, there is something here that obeys my laws. I will engage it." When this happens, the spaceship will vanish, divorced from space-time. The Brout field is now a hyperspace object. It will obey the laws of physics for the brout hyperspace where the speed of light is 5X faster. Relativity will occur at c'=c_B = 5c.

What do you think?

Dear Jason,

I'm partial to Higgs-brane, Goldstone-brane or Yukawa-brane.

I'm working on a variant model that implies Spacetime is (3+1)-dimensional, and Hyperspace is comprised of a 5-brane (I think that this decomposes into a 2-brane Hyperflavor-brane plus a 3-brane WIMP-Gravity-brane) and a (2+1)-brane of (let's call it) Higgs-brane.

Being a broken (2+1)-dimensional brane, we can have anyonic statistics in the 2-D plane. This might allow 'scalar fermions' to have the proper fermion characteristics in the unbroken 3-D, but have scalar characteristics in the broken 2-D. This might be an important part of the scalr fermion/tachyon/Higgs relationships.

This broken (2+1) dimensional Higgs-brane builds up a (nearly spherical) buckyball lattice.

Now we have ideas that tie in with Hans-Thomas Elze's discrete spacetime ideas, Constantin Leshan's 'vacuum'/'hole quanta' ideas, Steve Dufourny's Spherical (nearly spherical or nearly buckyball?) ideas, Garrett Lisi's generational triality (and related CKM and PMNS matrix applications), Lawrence Crowell's G2 homotopy ideas (a String theory triality?), your Higgs field FTL ideas, and my 'crazzy' 12-D ideas.

I don't know. My brane is tired.

The M2-brane in the 2+1 brane world volume is dual to an NS5-brane, or black brane. The 5-brane corresponds to the stretched horizon of a black hole --- in "braney form," which is timelike. The M2-brane is the dual structure corresponding to the quantized singularity of the black hole.

Dear Lawrence,

In the truncated icosahedral model, the NS5-brane corresponds to 6-simplices that are represented by Petrie hexagons. There is a homotopy between two concentric truncated icosahedra and a torus. The dual lattice to the truncated icosahedron with 60 vertices is a pentakis dodecahedron with 60 vertices. These (60+60) vertices give the 120 components of the icosahedral conjugacy classes (compatible with SU(11) and similar to H4). And two concentric truncated icosahedra with their two dual pentakis dodecahedra yield 240 vertices (the roots of E8?).

The reason for E_8, or the nonassociative E_8 in the Jacobi exceptional algebra is to introduce a needed ingredient in black hole quantum physics. The stretched horizon concept or holography clearly shows a manner in which certain conflicts in physics can be solved. Yet this does not show why Hawking was wrong. Hawking argued that fields on the singularity and the inwards and outward scattered fields commute because they are on spacelike and time like (or null) surfaces respectively. Holography does not show this argument to be wrong. I maintain there are associative order of channel states for the S-matrix, which act as the needed uncertainty ingredient which construct the commutative structure Hawking sites as missing.

I vote for realism, not for sometimes misleading pragmatism. FTL can either be possible or impossible. I consider singularities unreal models.

On the topic of realism, if there is some additional component to the laws of nature, a component that physicists have have not observed directly, it will show up in nature via evolution. Evolution and the ongoing survival of living organisms will use every tool at its disposal, even if it has to reach into and use very noisy quantum mechanics. Obviously nature has been transmitting information content, genetics, for a lot longer than the physics community. On that note, when I come up with what sounds like an outlandish idea, I also have to check to make sure that I can find examples of where nature takes advantage of it. While weak coupling and the misinterpretation of occasional great "strokes of luck" might obscure the existence of a second space-time that coexists with our observable space-time, there are advantages to checking with an open mind. There is no absolute law that says that every phenomena observed in nature, must lend itself to the exact dictates of physics and engineering.

I had mentioned in another post that a second space-time might reasonably be expected to exist. The molecules of this particular space-time would be well integrated into our biologically and would be observed as particles of "thought" with an existence independent of the biological brain. If that were so, then the nature of the interface between this space-time and the suspected "aethereal brane (plane)" would be buried within the architecture of the brain, most likely starting with the early reptilian brain. While Occam's razor might work well enough for cosmology, GR and quantum mechanics, the DUAL of Occam's razor (its opposite) might be a common occurence in a biological setting.

A pragmatic way of dealing with something is based on practical consideration rather than theoretical ones. Euclid's definition of numbers as measures and Aristotele's "infinitum actu non datur" were not pragmatism but the result of consequent reasoning. Likewise, bra-cuts differ from Dedekind's pragmatic cuts.

Theories must not be remedied by arbitrary definitions or axioms. Cauchy still pragmatically used the irrational numbers as if they were rational ones. This was correct and erroneously considered not rigorous enough.

In contrast to belief and theory including the laws of nature, reality is not the way to imagine something but it is something that can reasonably be assumed to exist independent of its observers. Jason asked for an additional component to the laws of nature because he was trained in the belief that the laws of nature rule reality.

Let's assume the laws of nature are correct but incomplete. In particular any process in reality is obviously an open one, not a closed system. The laws of nature are not the nature itself. They were found by means of abstraction from necessarily restricted experience. Processes are causal, i.e. they integrate influences. Therefore, differential equations introduce a seeming additional degree of freedom. Correct use of DEQs demands to exclude unrealistic additional solutions, in particular the advanced ones in order to avoid getting nonsensical models.

Ben Akiba was there prior to those like Jason. For science fiction that arose from the Schwarzschild solutions see Zeh, 4th ed. p.138.

I would rather prefer believing in any religion than in theories that are not even wrong in the sense they cannot even be falsified. Are past and future singularities valuable for humans in the sense they give peoples an orientation? I see them just exciting because mysterious outpourings from unjustified interpretation of not tailor-made mathematics.

Welcome to the Monday MetaPhysics Club.

It seems to me that the LHC and current experiments have limited capabilities to discover: Higgs, Supersymmetry, New Generations, New Neutrino Physics, and New Weak-scale physics.

But these experiments have no capabilities to discover: TOE, String Theory, Extra Dimensions, Quantum Gravity, Black Hole Physics, FTL Physics, Time Travel, Consciousness, Dream, Soul, or God. Because we can't measure these (weakly-coupled?) phenomena directly, they all rightly belong in the category of 'Metaphysics'.

Therefore, I am proposing a Monday MetaPhysics Club where we all talk about our craziest ideas one day a week.

More likely you have, but your logic told you it must be a coincidence. In the movies, when something phenomenal happens, there is music, and the audience has be properly prepared; they are expecting something to happen. Reality is different; there is no music and it often occurs as something odd that can be disregarded or considered dumb luck.

@Peter van gaalen: Consciousness is part of psychology. Psychology is an introspective discipline. Causal science is an extrospective discipline.

I saw a psychologist because I was suffering from anxiety and depression. What a waste of my time! Nice guy, though. I told him many things, similar to what I've said on this website. But his interest didn't peak until I mentioned an improper sexual thought that bothered my me.

I've seen paranormal events throughout my life. I thought that physics could explain it. Well, I think it's more accurate to say that the mathematics won't be able to track reality "down the rabbit hole". We live in a multiverse with coexisting universes around us. The molecules and material substances of these universes are weakly interacting, yet evolution has taken advantage of it. Consciousness itself is an evolved sensory system to detect these extra-universal particles/substances/molecules. The result is: consciousness independent of the brain. Occam's razor still works; but skeptics and atheists have successfully gotten intelligent men & women to throw out data points/evidence.

Quote from Newton about Occam's razor: "We are to admit no more causes of natural things than such as are both true and sufficient to explain their appearances. Therefore, to the same natural effects we must, so far as possible, assign the same causes."

That is true. What we didn't expect was that proof of the paranormal would be impossible because physically biological consciousness evolved out of the paranormal. The mechanism is this: there are molecules/material substances floating around which are governed by the laws of physics of a coexisting universe. Evolution has partaken of these molecules and has used them to transmit information content. While this it too subtle for men/women of reason to notice, I can assure you that lives have been saved in combat, through periods of starvation, the holocaust, muggings, accidents and encounters with predators of every kind because, in a moment of live risking danger, someone listened to an inner voice or a instinct.

We set a cut off near the string scale Λ ~ E_{p}/100 and the energy E = 10^4GeV, the coupling constant at this semi-asymptotic free region is g ~ .1 then the baryon number, or equivalently the quantum numbers for quarks have a P ~ 0.0095 (nearly 1%) of not being detected, and instead the configuration is a black hole! I am being a bit optimistic on the coupling constant, but even still there should be measurable channel productions corresponding to an uncertainty fluctuation where the baryon number is absent and a black hole present ---- here signified by the cut-off in energy. There have already been signatures of this with the RHIC, though the statistics are not conclusive at this time. This is similar to the DM release a few weeks ago.

A single proton in free space has a certain probability for quantum fluctuating into a positron plus a boson. This sounds odd, for it violates baryon number. Yet the nuclear QCD force has a limited extent in space, and a momentum fluctuation of a certain magnitude can "hide" the baryon number in a fluctuation. So much the same can happen at high energy, and if a black hole occurs at a low energy the positron plus bosonic field can manifest themselves as fields held on the event horizon. This will then have measurable consequences, for the quantum decay of the black hole which reproduces the baryon number(s) will have particular channel productions.

Ray,

I think it is more the case that most experimentalists regard it as a 1/10 shot. I think the initial hope is to measure the Higgs boson, then to refine measurements to determine if there is MSSM Higgs, then get hints of supersymmetry, maybe produce neutralinos as DM and so forth. These probably outweight more exotic concerns of extra dimensions, black holes AdS physics with conformal fields and so forth.

I have made some progress with the g_2 and the AdS_3 ~ SU(3)xU(1). The g_2 breaks down to su(3) + 3 + 3-bar, here on the algebra level. The g_2 in the supergravity mupliplet is a holonomy associated with the gauge-like action of F_4. F_4 decomposes into the SO(8)'s. So there is an SU(3)xSU(3)_hxU(1) in the lower energy configuration (here in the group level). The low energy configuration is rather interesting with an EW-like breaking of the symmetry which decouples QCD from supergravity at lower energy which conserves a particular "charge."

I think we can work up a paper with polytope representation of this theory and how it breaks to lower energy.

Dear Ray,

You said,"I think that most of the LHC researchers are hoping NOT to find a mini Black Hole." Have you ever noticed that the pessimists are very often right? Given the irrational fright that uneducated morons (educated morons) have about the LHC generating a planet swallowing blackhole, a worst case scenario hysteria would develop if the LHC announced the discovery of a mini black hole. That would land the LHC in court for years while hysterical nutcases hold up signs showing babies being swallowed up by black holes. I'll bet money on this one, that the LHC WILL produce mini black holes. If they do start to notice the evidence, they might just ignore it for fear of a legal injunction, to discontinue collisions, from the scared crazies.

This connects with the SU(4) ~ AdS model you propose. The g_2 holonomy and the conformal QCD define at intermediate energy a SU(3)xSU(3)xU(1), which further decomposes via a weak angle into a broken SU(3), QCD and a charge define by the U(1). The broken SU(3) is what defines semi-classical gravity. In effect general relativity is not really quantized to high energy, but instead there is an underlying QFT given by the automorphisms of E_8 at high energy. There is then technically no quantum gravity to all orders. The emergence of gravity is involved with this process. There is a mixing of color charges in QCD with mathematically identical indices from the holonomy.

One of my favorite classical mechanical systems is a gyroscope that is the mass of a pendulum. There is a phase holonomy associated with the dynamics. The penudulum will have its amplitude oscillate in a π phase with the precessional motion of the gyroscope. This is similar to a coupled system of photons and a 2-state atom. We might think of the pendulum as the orbit in spacetime and the direction of the gyroscope as a parallel transported vector. When the pendulum is in its maximal circular motion the gyroscope points along the line of the pendulum and closes on parallel transport. This is zero curvature. Conversely when then pendulum is at minimal circular motion the gyroscope precesses at maximum. This is a curved spacetime configuration. The gyroscope is an analogue of SU(3) and the pendulum is an analogue of U(1) and the two are ~ SU(3)xU(1) ~ SU(4). The beat between the pendulum and the gyroscope is a quantum effect which changes the parallel transport properties on the spacetime according to this holonomy. The oscillation is basically the frequency of a graviton on AdS.

Jason,

Bogoljubov means Gottlieb. Cantor admitted having got CH directly from God. Modern physics does perhaps much more rely on Zeus than did Euclid. Well, when Albertus Maximus uttered God does not play dice, the community did not obey. However, virtually everybody accepts what he also said: For us believing physicists the separation into past, present and future has merely the meaning of an albeit obstinate illusion. The belief in an apriori given spacetime opened the door for anti-worlds, wild scientific guesses about the number of dimensions, warp drive FTL and like that.

I quote what the mathematician David Joyce yesterday wrote to me: "It's an interesting historical question what various philosophers thought about the relation between physical reality and what we call mathematical models of reality. It helps to make such a distinction, but the relation for some philosophers was identity, that is to say, they didn't make any distinction between physical reality and mathematics."

I intend to elaborate my much less important suggestion to slightly correct a basic notion of mathematics itself at topic 604.

I think this physics does lead to a low energy which is interesting. By low energy I mean energies which might be accessible to the LHC. There is a symmetry breaking structure similar to the standard model that involves a weak holonomy from the supergravity multiple (a holonomy involved with semi-classical gravity) and QCD.

I think I got off track a little bit. In order to have an FTL propulsion drive, you have to figure out how to represent the spaceship to a co-existing hyper-space; that hyperspace, of course, has a speed of light c' >> c. The problem one immediately encounters is: how do you generate or create a hyperspace field/warp bubble/something around your spaceship that makes this coexisting universe think there is something there that its hyperspace laws of motion can interact with.

The only co-existing universe I know of is something I call the aethereal plane. I think that the molecules that the endocrine system uses are what have to be interfaced with. In other words, there is a whole chemical library of molecules that the endocrine system workds with to establish communication throughout the body. This chemical library makes it possible for us to experience a huge number of feelings, moods and thoughts. I wanted to figure out what the interface would be like between those chemicals, and this aethereal plane. My break is over. I'll have more, later.

Hi Ray,

Let me clarify my terminology. What I am calling the Higgs brane is the only universe that is scientifically known to exist; our space-time. The Higgs brane derives its name from the Higgs field which gives mass to W+/W- weakforce particles. Since 'mass' itself is hard to explain, I decided to call the entire space-time of our universe, the Higgs-brane, because E=mc2. The Higgs-brane has the speed of light, c, built into it.

Assuming the existence of a co-existing hyperspace, I needed to figure out how its laws of nature/particles and forces would interact with ours. The only co-existing universe I know of (which is certainly very speculative on my part) is the aethereal plane. Some call it the astral plane. If you believe in heaven or hell, they would exist here. The aethereal plane (aethereal-brane) supplies the laws of physics that allow ghosts, spirits and the occult to exist.

From occult teachings that I am aware of, thoughts are considered to be real objects. I had the idea of describing them as something made out of aethereal molecules. A few days later, I realized that the endocrine system works this way. The endocrine system signals (passes information) using molecules. The idea of using aethereal molecules (which can be sensed psychically) allows me to explore how two coexisting universes can interface with each other. Aethereal molecules, or the unit components of a thought form, exist within what I call the aethereal brane or aethereal plane.

Since I am trying to figure out how two coexisting universes might interface, this is what I have so far. Molecules themselves are potential energy scalar fields. I had wanted to wrap these aethereal molecules around the endocrine system molecules, but that seemed awkward.

Platonic absolutes can be described as perfects thoughts/pictures/sounds/images of lots of stuff like chairs and cups; abstract ideas would also exist as platonic absolutes. I'm trying to describe a platonic absolute as something that can generate an n-dimensional potential field, so as to be able to attract molecules that have an affinity for this field. Unfortunately, I am running into problems with this model. It's as if mechanisms/logic/mathematics become awkward to work with.

So, at the moment, I'm having some trouble trying to figure out how to interface with a coexisting universe, particularly, a hyperspace universe.

Ray,

In supergravity multiplet the spacetime of 11 dimensions has the decomposition M^{11} = M^4xS^7. The g_2 fixes a vector direction on the S^7, as the transitive action on spin(7), a subgroup on spin(8), so that spin(7)/G_2 = S^7. On the “p-brane level,” the D4-brane is fixed with the D7-brane according to the holonomy of the G_2. Yet the decomposition of the G_2 - -> SU(3)x(3 + 3-bar), and the restriction on the SU(O) is a U(1), The breaking of this symmetry then determines the D4-brane with U(1) phase factors, or what might be called the Higgs phase of the D4-brane. This phase then describes small oscillations about the classical expectation of gravity or general relativity. So these are D0-branes (particles) with a phase structure on the D4-brane, which might be thought of as a “Higgs-brane.”

D-branes are strange in a way, for these are not really quantum fields as such, but more in the way of classical-like solitonic fields. However, from the lattice sphere packing perspective everything is made of D0-branes (lattice particles etc), and Dp-branes p > 0, are then in effect similar to the Fermi surface in condensed matter physics at lower temperature, with some compactification or orbifold structure. There are a range of mathematical structures here with 10 and 11 dimensions. To make things a bit weirder there is a correspondence with a 26 dimensional Lorentzian space, which corresponds to the 10 dimensional superspace, and the 11 dimensional space corresponds to the 27 dimensional exceptional Jordan space J^3(O). Upon compactification, or what is sometimes called the infinite momentum frame, one dimension is reduced. This is the domain where D-branes in 11( or equivalently 27) dimensions are wrapped into various configurations. In effect the 10 (or equivalently 26) dimensional Lorentzian spacetime is a "universe," and the one compactified dimension can be a parameter for the occurrence of different cosmologies. The Higgs brane, as we might call it, is associated with the particular orbifold compactification of these D-branes at lower energy.

All of this sounds very mysterious, but in a funny way a lot of D-brane physics is basically Gauss' law and Stokes law in basic electromagnetism — just in more generalized mathematical language.

Dear Lawrence,

Yes, I think we are on the same page. Spin(8) or Spin(7) decomposes into Spin(6)~Spin(4,2) and/or Spin(5)~Spin(4,1) with a G2 triality. I still think there is an important 12th dimension, so I am starting with a 12 dimensional M^4xSpin(8). One of these dimensions breaks down such that we don't see it directly - it simply adds in more 'curvature' than we should have. This is related to my buckyball ideas.

Jason, the Higgs-brane is the G2 (with 2-dimensional anyonic statistics), not the 4-dimensional Spacetime M^4.

This phase then describes small oscillations about the classical expectation of gravity or general relativity. So these are D0-branes (particles) with a phase structure on the D4-brane, which might be thought of as a “Higgs-brane.”"

In effect, Lawrence is describing the how D0 point particles spring up on the D4 (space-time); even he refers to it as a "Higgs-brane". The whole purpose of describing a Higgs-brane was to reach into the nothingness of space-time, identify something about it that was producing the laws of motion, and refer to it as a "something" that could be manipulated.

I had referred to the need to generate a hyper-space field around a space-ship. I borrowed the name of one of the co-discoverers, and called that field a Brout field. A Brout-field divorces the spaceship from space-time. The Brout field appears as an object in hyper-space. This particular hyper-space, called a Brout-brane, whose existence I defined for explanatory purposes, has a speed of light of c' = 5c. The Brout-field constitutes a particle/object governed by the laws of motion of the Brout-brane (hyper-space).

I'm not sure where or how the G2-brane fits in. Technically, the Brout-field that surrounds the spaceship (and divorces the space-ship from space-time) abuts against the spaceship's severed chunk of Higgs brane. The Brout-field is not supposed to intersect the Higgs-brane. This could generate a plane of some kind. By analogy, a balloon could be thought of as a two dimensional surface that divorces or separates the air on the outside from the air on the inside. In reality that balloon has a thickness of several hundred microns.

Dear Jason,

We are confusing ourselves with inconsistent terminology. Perhaps I need to write up a short paper and send it to you and Lawrence. I think the Higgs-brane is a badly broken (2+1)-brane - the 2-brane component allows anyonic statistics and scalar fermions/ tachyons/ Higgs, while the broken 1-brane is the 12th dimension - it pretty much disappears except for an effective contribution to curvature/ the Lagrangian (is this related to GR?). The Higgs-brane connects Spacetime to Hyperspace, and therefore, may allow your weird FTL applications.

Hi Ray,

I'm black boxing everything. I have several black boxes; I don't understand what is inside. But I give them names and assemble them accordingly. I know that space-time requires that E=mc2; curvature of space is causes by both mass and energy. Mass seems to be a property of particles. In other words, some mechanism of space-time gives the property of mass to particles. For Higgs bosons, that is the Higgs fields. Whatever the details are about how particles get their mass, I am black boxing it and calling it the Higgs-brane.

You said, "The Higgs-brane connects Spacetime to Hyperspace, and therefore, may allow your weird FTL applications." Connect? Do you remember when I described multiple space-times like a Russian doll? Another analogy would be something like structures of government. Houston is a city; its laws are called ordinances and are implemented by HPD. Houston resides with Harris Country; Harris counties laws are implemented by Harris country officers. Harris County resides within Texas; Texas has state laws that are implemented by State Troopers. Texas resides within the United States; its Federal laws are implemented by the FBI. I'm using the same sort of analogy. 4D space-time is a universe whose laws of motion are implemented by the Higgs-brane. The universe exists within hyperspace whose laws of physics I call the Brout-brane, etc.

I'm not sure if this approach is compatible with 26 dimensional string theory.

This 2-D lattice is the Higgs-brane. Each hexagon represents a Petrie polygon of a 5-Simplex or a possible 5-brane of Hyperspace. And each pentagon represents a Petrie polygon of a 4-Simplex or a possible 4-D Spacetime. There is a triality symmetry about this central hexagon, and every pentagon has a multiplicative pentality symmetry. If we add back the dimension that we lost by deflating and cutting up the ball, then we have 12=2+1+5+4 dimensions.

Of course we have to keep our dimensions straight. There are 27 dimensions in space with J^3(O), which in the "infinite momentum frame," or compactification reduces to 26 dimensions --- 3 octonions of dim = 8 plus a 2-dim scalar field which imposes the Lorentzian (or AdS) structure on the 26 dimensional space. It is this 2 dimensional scalar which obeys a Chern-Simons Lagrangian which is the anyonic portion of the theory. Now this 2-dim field, is involved with the triality, where the x,y,z fields, where z = z(x, y) due to the infinite momentum frame, have a duality with the octonionic fields (the supergravity multiplet of 256 Clifford Cl_{16} fields constructed from the 248 components of the E_8 or octonion. The action for the fields have cubic Lagrangian terms, which on the 2-chain level or the M2-brane are again anyons. The M2-brane is dual to the NS5-brane in the reduced 7-dimensions (eg spin(7)), which is in total an so(9) ~ B_4. This so(9) is the M-theory space in the Banks-Fischler-Shenkar-Susskind Matrix Theory.

The G_2 is a system of three forms (related to the 3-form of the Chern-Simons Lagrangian) which is the symmetries of a 2-dim tangent plane (or 2-dim subplane of a 5-dim tangent plane) to the S^5. The S^5 is of course the part which is dual to the AdS, and this does have symmetries SU(2,2) or spin(4,2) and spin(4,1).

Dear Lawrence,

Please help us clarify our definitions. From very basic string theory, a brane is something that a vibrating string sticks to, the way, a guitar or violin tightens down its strings. In short, a brane is something that a superstring connects to. If those superstring are fermions or bosons, then, if they are open strings, they will be attached to a brane. Right?

The 2D scalar field that imposes the Lorentizn AdS space, is that intended to describe a holographic perspective of the motion of particles?

Energy can take many forms. One form it can take is in the form of particles. A Higgs field is supposed to be the ubiquitous field that gives everything a mass. The idea of a Higgs brane was supposed to be to provide a name to the "thing" of which space-time, it's laws of motion, and its rules for particle creation/annhilation, to be described with, something tangible. Thus, we could say that a volume of geometric space would contain the Higgs brane. If I remove the Higgs brane from that volume of space, that volume of space is without laws of physics, cannot engage in particle creation-annhilation, and cannot transmit light. I could just as easily imagine changing the properties of the Higgs brane inside of this volume of space, and call that a Brout-brane. A Brout-brane is a term I made up to describe a different kind of space-time with a speed of light c' = 5c.

Ray said: "I think the Higgs-brane is a badly broken (2+1)-brane - the 2-brane component allows anyonic statistics and scalar fermions/ tachyons/ Higgs," What is this 2D object intended to represent?

To quote you Lawrence, "So these are D0-branes (particles) with a phase structure on the D4-brane, which might be thought of as a “Higgs-brane.”

"

Did you mean that the way it sounded, that a D4-brane (a.k.a. space-time) can produce D0-branes (particles), thus the Higgs brane is the part of space-time that creates/annhilates particles, enforces motion, etc?

D-branes are exactly line a musical instrument or the sounding board of a piano. The strings vibrate and these open strings attached to the brane transduce their quantum vibrations into the solitons of the D-brane.

The D0-brane is the point soloton associated with the Higgs-brane. The entire business of D-branes probably does reduce to particles, or D0-branes. Remember that strings were originally hadron, but then the string making up a meson was found to have quarks held by self binding QCD vector bosons called guons. Something like this probably happens with string theory and D-branes as well. Remember, D-branes are not quantum mechanical, but act as nonlinear systems which involve string interaction --- and transformations between strings. Yet this is not a fully quantum picture of things, which is a bit of a problem. I think D-branes are really similar to the Fermi surface in solid state physics, with an underlying lattice system and knotted fermionic field (Skyrmions) which define strings. This is the whole point of getting into polytopes, quantum error correction codes and so forth.

This 2-D scalar field is the surface of the soccer ball, or the remnants of my badly broken (2+1)-D Higgs-brane (the deflated buckyball).

How does my 12-D model connect with your 27-D model? My first thought was SUSY at least doubles the number of dimensions from 12 to 24+. Another thought is I have a triality symmetry. If each triality represents an 8-D E8 octonion (and we know that Garrett Lisi's E8 is self-consistent with one, maybe two generations, so this 'Higgs-brane'-related triality allows us to interrelate the three generations in a fully self-consistent manner), then we have 8x3=24-Dimensions that becomes 27-D when we also add in the 3-D inflated buckyball (or 26-D with the 2-D deflated buckyball).

Ray,

On the bosonic string level with compactification the J^3(O) reduces from 27 to 26 dimensions. There are three copies of the octoinions or E_8, plus three scalar fields. Upon this compactification or the lightcone gauge one scalar becomes dependent on the others z = z(x, y). This lightcone imposes a Lorentzian structure, which is 24 dimensions (the three octonions) plus one dimension that is spatial or temporal, plus the time dimension. In an AdS setting the 25 dimensions of space become 24 of space and one of time for a total 26 dimensional signature of 24 of space and 2 of time. The 24 dimensions is the Leech lattice Λ_{24}, which is an automorphism of the Conway groups, which are a subgroup of the monster group and the 26 dimensional spacetime is an automorphism on the monster or Fischer-Griess group.

The 12 dimensions comes from the Weyl group on the Leech Lattice as diag[H_4, H_4] + permutations, where the H_4 is the dodecahedrachoron or the 120/600 cell. This can tessellate the hyperbolic spacetime in AdS_5. Now this is in the bosonic string territory, where the dimension of the space treats the framed fields and their superpartners as independent. In other words the octonion O ~ E_8 in the J^2(O) is extended with two additional octonions in J^3(O). These additional two correspond to the superpartneres ~ ε-bar ψ and ~ εψ-bar for the spinor superpartner, ψ, ψ-bar and ε, ε-bar Grassmannians, to the vector fields in the original octonion. In the framed setting with a superfield

Φ = A + ε-bar ψ + εψ-bar + εε-bar F

24 dimensions get reduced to 8, and the three scalar fields in J^3(O) provide an additional 3 dimensions for a total of 11 dimensions. This is the superspace for N > 2 supersymmetry or supergravity. The lightcone condition on the three scalars reduces this to 10 dimensions, which is the reduced superspace with a compatified dimension. This connects the theory to supergravity. The 12-dimensions for the H_4 tessellates a hyperbolic spacetime in the AdS_5, which I think is the boundary on AdS_4 (∂AdS_5), and is dual to the S^5 conformal field theory space.

Although we have talked about E8 a lot. H4 may be a more important building block. Had Garrett Lisi used a triality of H4's, he could have properly modeled all fermions (although bosons are another challenge). Florin is using 2-D quantion building blocks that could be related to these 4-D H4's. Ultimately, I think this implies a 28-D (7x4) model, not 26 or 27.

I'm traveling next week. If I have time (I probably won't, but I want to) I'll try to pull together a phenomenological schematic of these ideas. Between the best of our ideas and abilities, I think we should be able to come up with something pretty good.

I think we should concentrate on the g_2 quark physics connection. I have worked out some stuff with and SU(3)^2xU(1), as an intermediate energy theory. We can worry about the extended theory with J^3(O) later.

As for extending this to dimensions higher than 27 (or the infinite momentum frame of 26 dimensions) this involves extending the diagonal these three scalar diagonal terms into 7 component terms, which are anti-Hermitian. Then the 3 octonions give 3x8 components and there are now 3x7 diagonal terms for a total of 45 dimensions. The infinite momentum frame reduces this by 7 dimensions and this is 38 dimensional. We may then "algebratize" these elements by G_2 to extend this by 14 dimensions to 52 dimensions. This gives an overall F_4 algebraic structure to the Jordan algebra. If we include the real component, eg the ordinary J^3(O) this extends this to 26 + 52 dimension, which is 78 dimensions. This gives an E_6 dimensional structure over the J^3(O). This is a quaterionic valued exceptional algebra. This with some additional work may be extended to 248 dimensions for an octonionic valued exceptional algebra. This is a sequence form J^3(O) ~ RxO^3, to the F_4 valued CxO^3, to the E_6 valued HxO^3 and up to the E_8 valued OXO^3.

Now if I were to reduce these to the supersymmetric dimensions these would be respectively 36, 62, 232. or without the infinite momentum frame 43, 54, and 226. I am not sure what to do with these. As for 28 dimensions the G_2 inclusion of SO(8) into SO(O) is a double covering which multiplies the 14 dimension into 28. The G_2 extension of J^3(O) into an F_4 might have some connection with 28 dimensions, and on the SUSY level the 36 dimension some triality condition on these 12 dimensions. Maybe this is the foundation of F-theory, which is in 12 dimensions. Of course I am speculating considerably here.

Dear Ray,

I've been spending time on a website I'm developing. It's everything you might expect from someone like me, and stuff you'd never even conceive of anyone writing about.

https://sites.google.com/site/ftlpropulsion/

I've been thinking about the hyper-drive. There is a possibility that I might not even need a hyperspace to be able to travel FTL. I'm exploring the possibility of simply making the speed of light around a spaceship larger. I don't have anything definite on this.

It is good to see you are well and still trying.

My NASA/UAH friend with the String theory/Stargate ideas passed away last month at the age of 72. I'm bummed out. We all have a limited amount of time to either make a difference with our ideas or pass those ideas on to someone else who can make a difference.

Hi Ray, and Steve,

I've been working on the website, but also I've been helping my girlfriend move. She has moved in with me, but now, we are getting ready to move into a bigger apartment. I can't believe how much stuff she has. In a way, it reminds me of physics. Physics is about how all of the stuff in the universe, how quickly it can be moved around, and how much back breaking energy it takes to move it. I had hoped I could discover the secret to gravity. All I've come up with is that women can be pack rats and they accumulate more crap. I did come to realize that stuff/crap has an entropy of its own. The more crap there is in some volume, the harder it is to find anything. It takes a long time to get it organized, and mere seconds to for crap to become disorganized. It's interesting to notice that when I have to move a lot of crap around, there is disorder left behind. OK, it's not that much like physics, but moving a lot of crap around really does take a lot of energy. Maybe gravity is the universes way of saying it also hates moving a lot of crap around.

Dear Jason,

Have you read Verlinde's paper relating entropy and gravity? The cause and effect part of it sounds strange to me, but it may be that much of Gravitational interactions initiate in an entangled Hyperspace, are transferred into Spacetime by a phenomenon such as entropy, and thus we have apparent action-at-a-distance phenomena - FTL!

My wife also keeps too much 'junk'. Our garage is full of it. I've asked her if we can just donate it to a local charity, but she wants to have a Garage Sale instead. I think she is waiting for me to organize a Garage Sale, but it isn't my stuff! I paid for it, but I don't have any say over it...

The Verlinde paper takes us further in a direction where where we can unify physics according to the three fundamental constants ħ, c and k_B, the Planck unit of action, the speed of light, and the Boltzmann constant in statistical-thermodynamics, along with the gravitational constant G, or more fundamentally the string constant g or α’, with the gauge coupling hierarchy system and the cosmological constant, The Verlinde paper is a step towards putting thermodynamic (geometro-thermo-dynamics) on an equial status with quantum physics and relativity.

Lawrence B. Crowell replied on Feb. 10, 2010 @ 18:11 GMT
Hyperbolic groups SO(m,n) and the rest have orbits with modular realizations, such as SL(2,R) for the Poincare plane. A system of theta functions with modular structure can define a partition function which is volume preserving, such as Jacobi-θ functions. It is the possible to have a geometro-therom-dynamic system which perserves quantum information. The entropy for two entangled systems is S(A) = S(B), as the eigenspectra are identical. The total system sith A and B is a pure state so that

S(A + B) = S(A) + S(B) - S(A|B)

which is zero. The entanglement here represents two sets of states for the exterior and interior of a black hole with their unique S-matrix, but where the two are related by modular transformations. In the case these are Jacobi-θ functions for the Leech lattice of E_8s. Hence the net system has conserved quantum information. Yet for an observer, say an exterior observer, that has an incomplete knowledge of the entire system, they only observe S(A) > 0 where S(A) = kA/4L_p^2, A = area of black hole = 4π(2m)^2.

I liked the idea of considering space to be just a storage place for information. As I read through the Emergence of Newton's Laws chapter, I kind of like what he's saying. I appreciate the fact that he considers lowering a particle using a "fictitious" string. Anyway, I'll let you know if I draw any insight.

Dear Ray,

I figured out how the hyper-drive works. If it works at all, it has to work this way. Here are my assumptions:

1. Space-time and hyper-space exist in the same 3D space. Space-time is implemented by a Higgs-brane. Hyper-space is implemented by a Hyper-space-brane.

2. Standard model particles emerge from the Higgs brane. Hyper-space particles emerge from the hyperspace brane.

I got this idea from considering black holes. One characteristic of a black hole is that its information content can be considered to exist on its surface. Now, here is the basic hyper-drive...

In hyper-space, there exists a shell; it can be spherical or shaped like the spaceship. From the point of view of hyper-space, only the surface exists. There is no way to penetrate, breach or get inside of the surface of the shell. The spaceship itself is made of atoms/molecules or particles space-time (Higgs brane). When the spaceship is docked, floating around, or landed in our universe, The spaceship's Higgs brane is connected to the universe's Higgs brane. When the crew decides to travel to Alpha Centauri, superluminally, the spaceship withdraws completely from our space-time. The spaceship is completely isolated inside of the hyper-space shell. The Higgs-brane of the spaceship is completely isolated from the Higgs field of the rest of the universe. The hyperspace shell is now an object of hyper-space. It is free to travel at velocities approaching the speed of light for hyper-space.

Any questions?

I am not sure what you mean by a Higgs-brane. A Dp-brane with mirror symmetry can compactify so that a G_2 symmetry gives an SU(3) holonomy has a set of Hodge indices for compactification. This is in a sense what might be called a Higgs brane.

The scheme you propose still suffers from the problems I outlined a couple of months ago.

Dear Lawrence and Jason,

I am assuming that the 'scalar fermions' of my model (equivalent to the 'ghosts' of Lisi's model) provide a Higgs-like interaction. These scalar fermions are not properly defined in the (3+1)-D Spacetime, but their intrinsic spin is at least defined in the M5-brane of Hyperspace. They can also exist as anyons in the M2-brane that contains the G2 triality symmetry. I'm not sure what to call these branes, but the M5-brane contains gravitational (and WIMP-Gravitational and Hyperflavor?) charges and field lines - call it Gravity-brane?, while the M2-brane - call it Higgs-brane? contains these anyonic scalar fermions that transfer an effective 'gravitational charge' from the M5-brane to Spacetime - perhaps by using Entropic processes as Verlinde suggests.

If everything is equivalent to Information transfer, then it seems that we must transfer information of ourselves (our DNA, our memory, etc.) from Spacetime into the Higgs-brane, travel 'instantaneously' as a tachyon/anyon wave, and then retransfer and reassemble that information of ourselves back into Spacetime.

The problems that Lawrence refers to would plague any Classical-like mechanism we can construct (tunnels, doors, etc.), so this must be a weakly-interacting 'Bermuda Triangle'-like quantum event. It is the only way to maintain the structural integrety of these separate branes. As such, these events would be so rare that they may seem Supernatural.

Have Fun!

Scalar fields with fermionic statistics (anticommuting operators) are ghost fields (Fadeev ghosts etc). In the Faddeev integral ghosts provide terms which cancel the central anomally in the Virasoro algebra to define a BRST charge. They are not exactly fields or particles in the standard sense of the term.

Back in 2002 I took my young kids to see a movie titled Monster Inc, which involves multiply connected topology --- doors which pop the monsters from their place to the rooms of kids. At one point the two main characters, the big furry guy and his side kick who is the green walking eye are on one of these doors as it is falling. They escape their crash at the bottom by stepping through the door. As I watched this my mind shifted some to the issue of what happens to time, for the falling door is falling deeper into a gravity field and its clocks slowing down according to distant observers. The monsters then step through and enter a region with a different clock rate. The next day I did some calculations to show how this does lead to inconsistencies in physics. I thought about writing a paper titled “The Falling Monster Door.”

Dear Lawrence,

By Higgs-brane, I am referring to the 'thing' that

(a) causes energy to manifest as particulate matter with mass (Higgs field),

(b) enforces/provides the mechanisms for the laws of motion, momentum, and relativistic motion.

(c) enforces E=mc^2.

A Higgs-brane is what causes a space-time to exist. If you want to think in terms of solid state, a Higgs brane is the crystal that causes space-time to exist.

A hyperspace brane is just a Higgs-brane with a speed of light c' >> c.

If by problems, you mean worm-hole/time travel stuff, we're not doing anything like that. When the spaceship is traveling in hyper-space, its Higgs brane is completely isolated from the rest of the physical universe. It is being frame-dragged (frame carried) by a hyper-space object/shell. That hyper-space object/shell is allowed to travel at velocities slower than c', even if v > c.

Dear Ray,

If everything is information content, then a hyper-space is equivalent to a faster parallel processor, where the Higgs-brane constitues an infinite parallel processor. By the way, I'm getting a profit share/bonus from work. I"m thinking about buying a newer, faster computer to process my information faster. Maybe I'll use a virtual computer to process some information very slowly...at the speed of light, c.

An M2-brane is defined by the scalar portion of the action in J^3(O), which has a cubic Chern-Simons Lagrangian. The scalars define C^2 in an elementary setting and with the anti-hermitian part of the matrix C^4. There are then some decomposition of this with different topologies and central charges. The cubic term is "Higgsian-like." Further, which restricted to 2 dimensions there are anyonic statistics involved. So while I don't agree with Ray that the ghost fields are Higgs, there might however be some fermionic content involved.

The M2-brane is a "defect" in the vacuum or in a space, where strings interact in such a way as to transform between their various types. In the case of the M2-brane these are a defect L_s/c from the singularity of a black hole. It is the physical element of the black hole that replaces the infinite singularity as a "fiction."

I would suggest that the last thing you would want to do is be anywhere near this. The force this object would exert is ~ 10^{44} Newtons, with a tidal force of comparable value across a string length. In other words, you will fair far better by jumping off a 100 meter cliff into a crucible of molten steel than getting anywhere near this.

Dear Lawrence,

I think the ghosts are Higgs-like in the way that they transfer mass to fermions, but clearly this is not identical to an SM Higgs doublet pair that provides longitudinal degrees of freedom for the W's and Z. There are more ghosts, and there are chromo-ghosts. The ghosts are a defect in Spacetime - my interpretation of a quantum version of Leshan's hole. These ghosts/tachyons/scalar fermions would most likely rush off to the nearest Black Hole where they are transferred to this deadly anyonic M2-brane.

J^3(O) represents 3 dimensions, but the M2-brane occupies two of those three dimensions - the 2-D surface lattice of the 3-D buckyball.

Space-time is nothing more than this property of our universe that all motion between any two objects is gauged by a speed of light that is the same for all observers. Clocks can run slow and distances can contract, but the speed of light is always the same. Because of generalized momentum (motion) calculations, E = mc2. We can talk about the rest mass of particles; but if we want to move them around we have to spend some energy from our "energy budget". If only they weighed less, we could spend less energy to move it. If the speed of light were larger, c', then we could get by with using less energy. In other words, mass is the energy cost, how much energy we have to use, to move our particles/objects around. Mass is like an expense to motion. A faster space-time simply lowers the cost of moving stuff around. A Higgs field, the mass giving field, is just the hassle/cost/expense that we're trying to mitigate. It is the cost that space-time's processes of motion demand for the priviledge of moving stuff around.

J^3(O) is 27 dimensions. The 3 represents the size of the matrix (3x3), with three cospies of the octonions, 8 dimensions each, plus the three diagonal scalars. The trace condition plus triality determines the Lagrangian, which is a Chern-Simons Lagrangian for the scalars. This is a field theory for the anyons, with the infinite momentum frame condition that reduces the dimension from 27 to 26 for the bosonic string.

The M2-brane, which has physics similar to graphene and a quantum Hall effect, is the place where tachyonic open strings get glued to. In the early universe they either ended up there or they went of to "infinity."

Dear Lawrence,

Of course, J^3(O) is 27 dimensional. What I am trying to say (and apparantly awkwardly) is that we have three Octonions for 24 dimensions plus this J^3 operator that supplies an additional 3 dimensions via the 3x3 matrix. This effectively 3-D J^3 operator becomes a 2-D G2 triality (with buckyball symmetries) on the M2-brane. I have been calling this M2-brane the Higgs-brane, but it is NOT an SM or MSSM Higgs, therefore I should probably call it the Ghost-brane (no I'm not being superstitious). The third dimension of the J^3 operator is the radius of the buckyball - this represents my '12th' dimension and the maximum allowed curvature at the Black Hole 'singularity'. The center of the Black Hole is a soccer ball of quantum lattice. This is that 'crazzy' ground where my ideas might overlap with Steve Duforney's ideas.

Dear Jason,

Earlier I said that FTL must involve 'Quantum Gravity' (if it even exists), and was therefore a weakly coupled quantum event at best. Upon further thought, I think you have to travel to the Black Hole 'singularity' where Quantum Gravity has a coupling of order unity, and is no longer a weak coupling. Our physical bodies could never survive such a trip, thus our only option is to send information into the Black Hole and hope that it remains entangled.

Dear Lawrence,

I do apreciate your explanations.

Everyone,

Sorry to end my post so abruptly. By describing mass as a "cost in energy" to change velocity, I was trying to suggest the existence of a set of mechanisms which are responsible for motion. For our space-time, I wanted to call the set of mechanisms that allow for motion of standard model particles, I wanted to call it a Higgs brane. Technically, a brane is a superstring theory word that superstrings are attached to. I would think that a particle (a superstring attached to a brane), would have to obey the laws of motion for the particular brane that it is attached to. Of course a hyper-space brane would allow for faster velocities of its particles, without any additional energy - because the mass is smaller for an equivalent amount of energy in the form of matter.

The "thing" that makes the laws of motion 'work' for space-time, it has to be called something; unless you have a better name for it, calling it a Higgs-brane makes sense.

One way of looking at physics is to say that: it is all information being acted upon by operators that process information. B = R (A) where A is the initial state (information), R is an operator that acts on or processes information, and B is the final state of the system, the final state of information. How fast does operator R() act on a system/information?

I have thought for a long time that gravitation was involved with the Higgs mechanism. Others have thought so as well, and articles have been written on this. However, nothing definitive has been shown as yet. I attach a diagram of a black hole where the holographic stretched horizon and the M2-brane are indicated. These two membranes have conformal fields (CF) which have a duality, or determine an S-matrix for CFs on non-commensurate causal domains of support. The nature of this duality is the crux of the problem with quantum gravity. The M2-brane is where strings are frame dragged to v - -> ∞ and the transformation of closed strings to open strings induces a Regge pole which is imaginary, corresponding to tachyons. This seems to connect with Vafa’s hypothesis of tachyon condensates.

Again the physical conditions are utterly extreme. You would find conditions far better if you set up your dream home on a neutron star, than trying to negotiate the situation in a black hole interior. Also as you can see in the Penrose diagram, the M2-brane does not causally connect to the exterior world. This is the basis of the problem I am working on: A duality between conformal quantum fields on inequivalent causal domains. So the problem with trying to enter a black hole to manipulate this brane is that the elementary particles which compose your self are strings which are transformed into tachyons that are “glued” to the M2-brane in a condensate. That is about as dead as you can get.

The problem with tachyons is that, as lattice defects, that lack any capacity to engage in the mechanisms of motion. That cannot transfer any energy over any distance. If you want to say that tachyons can exist within another kind of lattice, a hyper-space lattice, in which they can carry energy over some distance, then they may yet be useful. But they have to be able to obey the mechanism of motion for some hyper-space, particularly, the GR/SR of that hyper-space, beta = v/c', and the corresponding gamma. If they can do this, then they can still exist within a temporal/spatial framework.

Dp-branes are similar to the Fermi surface in condensed matter physics, and strings are further similar to Skyrmion knots or vortices. This is in line with what I think is a lattice system, such as E_8 or the Leech lattice quantum error correction codes. This would put branes on a more equivalent quantum status with string. However, if we just consider a brane as a defect in space with soliton physics equivalent to strings (which is how they permit strings to transform between types), then there are various dualities between branes in 10 and 11 dimensions. The M2-brane is dual to the NS5-brane, or black brane. So the M2-brane is a stretch membrane dual to the stretched horizon and is defined as a compactified D3-brane on the singularity of a black hole. The singularity is a spacelike (3-d) surface where the Weyl curvature diverges. A D3-brane may then exist within a string length of this, where the string tension defined by a compactification D3-brane to M2-brane and the Heisenberg uncertainty principle keeps this surface away from the singularity --- or a singular condition. The one dimensional compactification of the D3-brane defines a circle of compactified 1-dim with some string tension tied to the M2-brane This maintains the tension required to keep the surface from a singular condition.

Dear Lawrence,

Allow me to clean up some confusion. I would never use a black hole to achieve FTL propulsion. That's just too much energy to have to carry around.

For FTL propulsion to exist, there would need to be a second co-existing space-time with a speed of light c' >> c; we can call it a hyper-space brane (unless there is a better name for it). But what is a brane (rhetorical)? A brane is something that strings are attached to. Strings, in this case, are just particles. If I move my spaceship into hyper-space, I effectively take all of those proton/electron our of space-time (what I call the Higgs-brane), and send them to the hyper-space brane. All of those superstrings now suddenly find themselves in a new/strange environment. All of the super-strings now have to reach equilibrium with their environment. The possibility of disintegration cannot be ruled out. Therefore...

We need an object that can travel superluminally,... with a space-time core. We put the space-ship inside of the space-time core, the apple peel, to use a fruit analogy, is a hyper-space object/hyper-space brane. And voila... we have a hyper-drive.

I indicated that a D3-brane which defines a singularity membrane a string unit of proper time from the classical singularity. The M2-branes connected by strings are a stack of branes where connecting open strings maintain a quantum tension which maintains the dynamics of the stack. These strings may move (dynamically evolve) along any M2-brane according to anyonic statistics. The space between each of these M2-branes is a vacuum with an impedance, similar to the impedance of free space in electrodynamics at R = 377Ω, which is compared to a semiconductor layer between P and N layers. The closed strings which are attached at both ends to each M2-brane contribute a topological charge to the M2-brane, which if that charge Q = (1/4π)∫F/\F is positive or negative is analogous to the P and N dopant P and N layers in a diode. However, in the space between these layers (M2-branes) are the conducting strings which as a quantum field act as a gate voltage in a MOSFET. This sets the quantum tunneling barrier for vacuum energy into a nascent cosmology, or how cosmologies can spontaneously emerge. The vacuum removed from these conditions may also similarly permit the tunneling of a cosmology, but the probability is far smaller. The laminated stack of M2-branes has a bias voltage which increases the tunneling probability for this. As such the stretched singularity here is a system similar to an array of transistors, which we might compare to a type of stochastic logic device.

Dear Lawrence,

You said, "The space between each of these M2-branes is a vacuum with ..."; I take it you mean that these M2-branes are objects inside of regular space-time? Of course you do. I just want to get your feedback on my approach to a multiverse of multiple space-times.

Particles in space-time can be thought of as vibrating strings attached to a brane. I want to assume that super-strings and branes are

(1) different manifestations of the same basic "thing", from which physics is 'made of';

(2)branes are like the copper wire in a circuit, they allow electrons to move, and

(3) without a brane, super-strings (particles) cannot cross.

A particle, via a field, can tunnel (cross a small gap). By that logic, then a quantum particle/field can be its own brane.

This is what I'm getting at. To create a hyper-drive system, I need to get two branes to directly couple/interact. Like the particle-space idea I mentioned a while back; space-time itself can be treated like a quantum particle because (1) space-time is a brane,

(2) conservation of energy can induce fields which can cause a brane to form (to allow tunneling) for a small enough gap or a large enough potential energy.

I am attempting to isolate the connection between what a brane is, what a particle is, and how the laws of motion come from the brane/particle combined.

What if these stacks of M2-branes are concentric buckyball shells in its own 3-D Hyperspace (ghost-brane, whatever we want to call it...) with strings (connecting to Spacetime and the gravity-brane of Hyperspace) attached to each buckyball vertex. Somehow a string or lattice tension prevents all of these stacks from collapsing on each other and thus implies a fundamental quantum lattice behavior to the ghost-brane of Hyperspace (and possibly all of Hyperspace and Spacetime). Two concentric buckyballs of identical size and orientation can be continuously deformed into a torus. Is it more favorable to work in a concentric buckyball geometry or a concentric toroidal geometry?

The standard idea is that the M2-branes are infinite sheets, and these form a lamination which are connected by open strings which cavort about.

The M2-brane is dual to the 5-brane, called black brane. I have been doing analyses on a related issue with the quantum phase structure, a quantum critical point, of the stretched horizon and its relationship to the structure of elementary particles. Zamolodchikov demonstrated how a mirror potential in a scattering matrix for massive particles leads to an E_8 (8,1) representation for 8 "mesons." A BPS black hole near the extremal condition I found has this S-matrix structure. The ratio of m_1/m_2 is the golden ratio

m_1/m_2 = (1 + sqrt(5))/2.

The 8-irrep of these particles is an E_6xSU(3) rep of E_8 which is

(8, 1) + (1, 78) + (3, 27) + (3-bar, 27-bar),

which embeds into the 78-dimensional E_6 form of J^3(O) and the basic 27-dimensional real form of the J^3(O). If have been burning on this since last December. This (8, 1) part of the representation is given by the permutations of the (1, -1, 0) elements, which physically is equivalent to the Ising spin model with the Hamiltonian

H = Σ_i [S^z_iS^z_{i+1} + hS^x_i].

Here S^z_i the spin up and down operators for the (1, -1) portion and the S^x_i spin direction along the equator of the Bloch sphere corresponding to the 0 direction.

A. Zamolodchikov is one of those Russian geniuses who worked out the renormalization group flow for c = ½ conformal field theories. This result by Zamolodchikov is an emergent symmetry with conformal fields. I am writing this up and can send it to you ASAP.

BTW, I think we should shift discussions away from this warp drive 2180 page. I am running at 7-meg and this page still takes a bit of time to load.

Cheers LC

This is a warp drive thread. I'm talking about an experiment that might lead to the warp drive.

Frequency shifting across a wide frequency range, with a high repetition rate, and high resolution is the most logical direction for physics to pursue. This will also result in gravity field generation by opto-electronic means. Gravity already causes light to frequency shift along the radii of a black hole. I suggest that we try this in reverse.

We need to generate a linear frequency shift of the form Y = mX+b. The electric field component of the Poynting vector can be written as,

E = E_0 cos(2pi*f*t). What I want to do is make the frequency linear with respect to time, so I would write the frequency as f(t) = [df/dt]t + f_0. Next, integrate f(t) with respect to time; note that df/dt is treated as a constant. So we get,

Theta(t) = INT f(t)dt = 1/2[df/dt]t^2 + f_0*t+Theta_0.

We substitute this into the Electric field component of the Poynting vector to get: E=E_0 cos(2*pi*[1/2(df/dt)t^2 + f_0*t + theta_0])

This is what we need to emit as light (E&M) to induce a gravity field.

This will lead to new physics.

A linear change in frequency would look like,



If you integrate this with respect to time, you get a phase,



The electric field component of the Poynting vector of a frequency shifting photon should look like,



This is what you have to emit from your emitters to induce a gravity field.

Can someone explain what the physics community is doing to develop warp capability, and why that strategy will work?

Last night I bought the movie, the Day the Earth Stood Still. There was a scene where Klaatu (played by Keanu Reeves) is rewriting the Einstein equations. The scientist writes "=0". Klaatu draws a line through it that reads as "not equal zero"; the scientist looks at Klaatu, shocked.

The physicist community really could pursue warp technology if they really wanted to. It is too bad that they don't.

What if it turned out that extraterrestrials and flying saucers were real? What if they were warp propulsion experts? What if they were willing to teach us how to warp space-time to achieve subluminal and superluminal travel? It might look like this...

The aliens chose Ellington airforce base to perform their demonstation. Their rather large saucer shaped spacecraft was parked on the pavement. Grey aliens with big black eyes walked up and down the ramp, carrying out spare parts equipment from their warp engines. Soon the experiment was set up. It consisted of a square shaped warp engine with colored glass on one side, which was facing downward about six feet off the ground. The other sides of the box were silver; a cable ran from the box to the alien "professor" who began to speak.

"There is another term in the Einstein equations that describes how localized gravity fields can be generated. While mathematical physics has helped you in some ways, it has failed to shed light on warp drive physics which we will show you now."

The alien picked up a rock and placed it under the warp drive box. He pressed a button on the control, and the rock begins to rise off the ground.

"The box simply duplicates gravitational time dilation be emitting a range of frequencies, from 400 to 800THz, every 10nano seconds. The frequency shift is linear and is described as follows..."



"You will recognise this as the equation for a line. Delta f/Delta t is the frequency slope. For this experiment, f_0 = 400THz and df/dt = 4x10^25 cycles/sec^2. The description of the experiment is that easy. The engineering will be very difficult at first. If you perform the experiment, you will have to minimize discontinuities in the phase during the frequency transition. Maintaining a smooth phase without disconintuities is the real secret to warp drive engineering"

"Welcome to the era of the warp drive. We bid you peace and farewell."

The aliens decided to return to Ellington airforce base to perform another warp drive experiment/demonstration. But this time they performed the experiment with equipment and materials that might be available on earth.

Equipment includes: DC voltage supply, jewelery scale that reads micrograms, 100g weight, a clear polyethylene cylinder large enough to encapsulate the scale, and an earth technology gravity field generator.

The gravity field generator was made from a 6" galium arsenide wafer with gallium and aluminum doping. By varying the amount of gallium and arsenic doping, 16 separate colors (frequencies) were produced in block patters like that shown below.

XXXX

XXXX

XXXX

XXXX

The six inch wafer is carefully wired to an electric circuit. Both of which are placed on the polyethylene cylinder with the wafer side down facing the jewelery scale with the 100g weight. Using a 100MHz clock, each of the sixteen LED frequencies is flashed for 10nanoseconds. The entire range of frequencies is flashed in sequence for a repetition period of 160ns.

Four gray aliens stand around the apparatus. The scale is turned on, zeroed out. Then the 100g weight is placed on the scale. The cylinder is placed over the scale. The GaAs wafer and electronic driver is placed on top.

100 g weight measures at 100.0001 grams.

The driver is turned on, and the wafer glows with an ominous white light. A current meter reads 988mA.

100g weight measures at 85.0332 g.

The current is turned up to 2.023 amps.

100g weight measures at 61.876 g.

The current is turned up to 4.005 amps.

100g weight measures at 11.835 g.

The current is turned up to 5.000 amps.

100g weight measures at 0.000 g. The 100g weight floats up to the gallium arsenide wafer.

This is how frequency shift is used to create a time dilation field which, in turn, induces a localized gravity field.

There are two kinds of time dilation: relativistic time dilation and gravitational time dilation. They both result in a relative velocity between two inertial frames.

An experimentalist could attempt to simulate a time dilation field by emitting a frequency shift, from f_1 to f_2, in a short time period. Is this a possible way to induce a curvature in space-time,...which is a gravity field?

Hi Jason, It is sad that Ray is not with us. I liked to discuss with him.

Do you remeber our discussions several years ago ? With Lawrence, you , Ray, me. It was the good time. I am direct and frank, Ray was a friend for me. I don't understand why FQXi do not make a resume of his works, an article for him !

He merits it. I was at the opposite of his ideas but he was my friend. I am remenbering at the begining here on FQXi. He named me the spherekeeper. He was the first enthousiast about my theory of spherization. He said me, I don't understand how I have not seen this evidence before.

In fact I liked this platfrom due to him mainly.

Peace to his soul.

have fun he said , he had reason in fact.

When did Ray pass away??!! I had no idea. That's very sad. You're right, FQXI should write an article in his honor.

Hi Jason,

several weeks ago. It is very sad indeed. I am persuded that they shall make several articles about him and his ideas.

hi everyone. i am a soc psych pdh student, would like to confirm whether my equation is acceptable or not (my research is on sum rules of cognition)

U=u(Ptx+Itx)

where

U: universe; u: universal constant; P: perpetuation; I: interference; t: time).

I am currently writing a paper that will deduce this equation of universalities of information, and discuss consequences thereof in the system of human cognition.

Hi Orsi,

could you tell us more?

What do you mean by Universe? As you are talking about cognition, do you mean all of the information in the universe, or how the universe is perceived to be or something else? What is the universal constant needed for? What is X, an idea, thought, fact, piece of information,something else? Is this about information or ideas persisting within society, societies opinion of the universe, or an individual's perception of the universe, or the Universe itself as the "cosmic whole", or something else?

Acceptable to whom? Lots of ideas are shared here. It seems to me that most of us seem to disagree with, or fail to understand, each other on a regular basis. Though we all think we are talking sense and have something to say that -we think- is worth sharing. At least it seems so at the time. John Merryman said, if I recall correctly, - "there are no impartial judges here".

Hello All, I am scrutinizing this warp drive article.

http://www.boomslanger.com/images/warpcourse.pdf

If there is an expert in quantum vacuum physics out there, I need help. I need to find the equation that describes the differential change in quantum vacuum pressure versus a change in distance. Thank you. :D
