Can we detect the existence of parallel worlds in the lab? Quantum physicist Vlatko Vedral checks out the suggestion that a new—and surprisingly simple—experiment could tell us if alternate universes exist, once and for all.
From Vlatko Vedral:
Parallel worlds are a staple of
science fiction and
fantasy, with characters weaving in and out of alternate universes and interacting with other versions of themselves. Back in our universe, some physicists, including FQXi’s own
Max Tegmark, believe that parallel universes are simply a
natural extension of quantum mechanics. In such a scenario, both Obama and McCain will win the upcoming election in different universes, and there’s even room for an ultra-liberal
parallel version of Stephen Colbert to comment on it.

But can we ever know for sure that such parallel universes exist? There’s no definitive evidence for or against parallel universes—and it’s often debated whether the idea could ever be tested. At the moment, whether you choose to accept their existence or not seems to be more a question of personal taste—how unnerving (or comforting) do you find the suggestion that there are an infinite number of universes, with other “yous” that made different choices? So when I saw a
paper by Frank Tipler at Tulane University in New Orleans suggesting that not only is there an experimental test that can tell us if parallel universes exist, it’s so easy that it could conceivably be carried with equipment that you could find in many high-school or college physics labs, I wanted to know more.
Tipler is proposing an experiment that can differentiate between the standard “Copenhagen interpretation” of quantum mechanics and the less conventional Many World’s interpretation, first proposed by Hugh Everett just over fifty years ago, which gives rise to parallel universes. Both alternatives attempt to make sense of one of the paradoxes of quantum mechanics: Before observation, the properties of particles and atoms are undecided; instead, quantum objects are described by a “wavefunction” that simultaneously holds many mutually complementary properties.
In the 1920s, at a meeting of quantum bigwigs in Copenhagen, this weird property was explained away by postulating that when the wavefunction is measured (or observed), the wavefunction “collapses”—settling into one particular classical state. Before any measurement is made, you cannot predict with certainty the outcome you will get—just the probability of finding a particular result. That is the standard interpretation of quantum mechanics. But just how, when, or why this collapse should occur remains a mystery.
Everett took a different tack. He proposed a collapse-free quantum theory, by suggesting that quantum laws apply to everything, not just to atoms and particles on the smallest scales. According to this view, the entire universe could exist as a superposition of many worlds—or parallel universes. The upshot is that if you make a quantum measurement, every possible outcome of that experiment is realized—each one existing in a different parallel universe, with a different parallel-you reading a different result. (See the FQXi article,
“Squishy Bedrock” (pdf).)
The whole thing is a bit reminiscent of the discussions of what the perfect form of a society ought to be in order to balance the discrepancy between the needs of individuals and the needs of the society itself. There are two extreme resolutions (just like Many Worlds and Copenhagen). One is to say that there are no individuals and only the society matters (socialism)—or in our case, that everything obeys quantum mechanics, even the entire universes. The other is to say that there is no society, but that we just have a bunch of individuals (this is capitalism and its definition comes from a quote by former British Prime Minister Margaret Thatcher: “
There is no such thing as Society. There are individual men and women, and there are families."). Here, that attitude corresponds to the notion that quantum mechanics is more fragmented only applying in certain regimes to certain things on small scales.
The key to testing which extreme is correct, according to Tipler, is to look at the probabilistic outcomes of quantum experiments predicted by both the rival theories. As I mentioned, the experimenter can’t predict beforehand what the outcome of a quantum experiment will be before she makes her measurement, but she can work out the _probability_ of getting a particular outcome. That’s true in both cases. The probability of getting a particular outcome is determined by the so-called Born rule, which has been verified experimentally. But if both alternatives—Copenhagen and Many Worlds—predict probabilities according to the Born rule, how does that help us choose between them?
Tipler’s answer relies on the fact that you need to perform the experiment many times, to verify that you are getting the expected probabilistic outcome. That’s true in normal experiments too. Let’s say you wanted to check that the probability of rolling a die and getting a value of “four” is one out of six. You will need to perform more than one roll. Even six rolls won’t necessarily be enough. To build up the correct pattern of probabilities, you’ll have to roll the die many many times, and slowly you’ll see the expected results emerge—turning up each die value one sixth of the time on average after many throws.
Similarly, Tipler points out that you need to perform quantum experiments thousands of times to see the expected outcome predicted by the Born rule. So while both the Copenhagen interpretation and the Many World’s interpretation predict you’ll end up with results in line with the Born rule _eventually_, just how quickly you will get there is different for the different theories. So just look at how quickly your actual experimental results build up to form the quantum pattern you expect, and you can use this rate to discriminate between Many Worlds and Copenhagen.

How tough would this be to test in a lab? Tipler proposes looking at the
“double slit experiment”. This is a relatively simple experiment using not much more than a lamp and a screen. A beam of light is split apart by two slits, producing a peculiar pattern of light on a screen, showing that light has both a wave and particle nature. It’s a standard experiment, typically carried out in advanced physics classes at school, or in universities, in basic classes in quantum mechanics. So, it would be very simple to carry out indeed.
It's an interesting idea. However, I have an issue with his approach. Tipler states that Copenhagen couldn’t give you the same result for obtaining the probabilities as Many Worlds. But this is not true. In fact, you just need to consider the screen as a quantum object and model the interaction between photons and the screen and then you can work out all the probabilities you need for any number of photons to hit any position at the screen. And this is a purely Copenhagen interpretation—we don’t need to think of the rest of the universe behaving in a quantum manner. Thus, Copenhagen can give you the same result as Many Worlds.
So sadly, I don’t think that this experiment will work. But my final thought is that I like attempts such as Tipler’s a lot. The motivation—which I very much sympathize with—for Everett’s original Many Worlds proposal and for Tipler’s paper is that in the standard formulation of quantum mechanics (Copenhagen) we have two very different processes: continuous evolution when the system is not measured and then an abrupt change due to the measurement. To have this difference between measurement and evolution is not nice and clean. There are now two ways of getting rid of the dichotomy. One is to say that there are no measurements (the Many World’s philosophy) and the other one is to say that there is no evolution (this would be the "ultra" Copenhagen view).
But maybe Tipler is wrong to be preoccupied with these two extremes. Much like the fact that every society lies between extreme socialism and extreme capitalism, it might just be that the correct view of quantum mechanics is somewhere between Many Worlds and Copenhagen...whatever this might be.

Research: Blackholes and Baby Universes - Hawking
I like the interpration of the multiverse theory as this: that each individual blackhole in our universe, creates another entirely seperate universe, that creates blackholes that also spawn blackholes, that creates other universes, which create blackholes... etc.
That way, one can have the "multiverse" theory, without the absurdity.

In response to JL Wallace: aren't those separate universe's different than the ones preposed in the quantum multiverse theory? Can those two multiverse theories overlap?
I do agree, though, on a nonquantum level, that theory of black hole universes sits very well with me.

What has been and is generating it?
Is there a meaning to the question : Where is this "Information" locatrd?
Information, may be defined as: "structered content which encodes meaning", if so - where does the "informatic" - meaningful layer of the cosmos as information come from (same questions about the "meaner" and in turn its origin)

Dear Dango,
I have been asking questions like this for months. "Where is Hilbert Space?" "How does every electron 'know' that it has a rest mass of 511 KeV/c^2, an intrinsic spin of 1/2 h-bar, and an electric charge of -e?" We physicists like to crank the math without asking the philosophical questions, but I think that the answers to this information content lies in conserved quantum numbers within Hyperspace.

Hi guys
I found this forum after making it halfway through Vedrals Decoding Reality and trying to understand why he concludes that information has to be a physical entity that complies with the second law of thermodynamics because deleting information from a memory (human or electronic) causes heat, as opposed to aquiring or storing memory.
I know there has to be some methapors or references in this statement that are unfamiliar to me. The closest I can get to getting my head around it is concluding that IF information has to be defined as a physical entity and comply with the second law, THEN deleting or forgetting information can be likened to removing it from my brain and/or computer and placing or losing it in cyberspace where it will contribute to entropy.
BUT this is a deduction based on an assumption which is very far from a proof.
My background is in economy and philosophy. If anyone has the patience to explain to me how the proof that information IS a physical entity should be understood I will appreciate it. Otherwise I will just have to file the idea as a reference or language game not applicable to the way I think.

Sissel,
Welcome. I think your questions might be more appropriate, and get more notice, in Vedral's FQXi forum, "Decoding entropic gravity" (topic 626).
The short answer is that the mathematical model for communication entropy (Claude Shannon, 1948) is identical to the model of energy entropy (Carnot, Clausius). If the world is made of quantum information, quantum gravity follows as an entropic phenomenon. Halfway through the book, you've only read the background -- the exciting conclusions from the research Vedral is writing about are in the last pages.
See you over in topic 626 if you want to go into detail. I'm a big fan of the book, and I'd be delighted to see the forum revived.

Well.
Banach space ....infinity why????
SECOND why this analyze about the diameter.
Furthermore the convergence must be realistic and thus why this infinity inserted in the uniqueness.
Thus a real and competent mathematician must understand the MAIN UNIVERSAL REFERNTIAL AND ITS PURE TOPOLOGY OF ROTATION OF SPHERES IN A SPHERE.A real mathematician understands what is a limit and an universal serie.
The utilization of spaces like Hilbert or Banach always must be inserted with rationality and pragmatism when we speak about physics.If not it's just sciences fiction and pure imaginaries where complexs dance without a real referential.
Pseudo sciences or real and objectives sciences.All is there.......

Hi Tom,
I am simply saying that the interactions of these quantum particles seems to involve more information (and more degrees of freedom?) than we see. Where is that information stored? Does the information 'piggyback' with the quantum particle through Spacetime? Or is that information 'stored' in a memory-bank-like Hyperspace that we don't see (and communicates with the hyperspace memory bank via FTL tachyons)?
Hi Sissel,
Tom is correct that according to Claude Shannon, information and entropy may be represented with similar mathematical forms:
S=-k*SUM(p_i*ln(p_i))
Hi Steve,
Remember that Nature has a dual particle-wave behavior. I think you are focusing on Spheres (particles) to the extent that you are overlooking Waves (strings).

Ray,
You ought to know by now when I'm yanking your chain. Anyway, though, "cranking the math" and ignoring the philosophy isn't a bad thing when one is dealing with questions of how to find information (e.g., particle position-momentum) because that's exactly why mathermatical models of physics exist in the first place -- to fix the domain that makes possible the calculation of the range. The Hilbert space domain of quantum physics works, because it obviates the time parameter of classical 3 + 1 spacetime, but still gives us a real result when we ask things like "what is the value of electron mass?" Hilbert space is right here with the rest of space, where we and the electrons live.

But dear Dr cosmic Ray...the space and particles are the same...and furthermore the waves are sphericals and the contact of all spheres, with or without rotation is the explaination of the waves by contact....the strings are falses Ray......really it was just a kind of fashion for the public that's all.
The spheres explain the duality.....the particlas and the waves...think about the first fractal(BB)...and after this kind of mitosis...a multiplication...thus our space and after the rotations implyiong mass...and the light to help for the building of spheres....3 main systems...1 linear with 1 sense/center of Universe,the light...the second this space without rotations and 3 the gravitational stability thus with codes of rotations the second main sense the fusion seems 2 or 3 ???hope you understand.....
It's totally different Ray than the add with strings.

Hi Tom,
I'm a Physicist, not a Philosopher. I understand that that we get results by cranking the math, but I also understand that "the map is not the object".
Hi Steve,
I'm yanking your chain...
I think that the Scale Invariance in my models unifies the Discrete (particles, spheres, Fermions, set of integers) with the Continuous (waves, strings, Bosons, set of Real numbers and Infinity). I'm not saying that Spheres are wrong - I'm saying that Spheres are only half-right.

Ray, I think you mean "the map is not the territory." Certainly, the map is the object that contains the information referring to the territory.
Deeper, if quantum information is all there is, the self organizing map and the territory are identical.

Hi Ray,
Sorry Ray ,but the spheres are all,the duality is just a different comportment.
The linearity or the gravitational stability.Thus I like indeed your idea about continuity and discreteness.It's just a question of sense of rotations Ray.
Thus in my logic you have false about the link.
On the other side I like also your idea about the infinity(adds of number of uniqueness)thus in your logic the space....and thus the real number is interesting but if and only if Ray you differenciate the number and the numbers.It exists a specific number of spheres for all unique and stable system.
Thus no you don't unify the two systems because you forget 3 essentials,TOPOLOGY ROTATING SPHERES INSIDE A CLOSED SYSTEM.
The continuity .........and discretnes...rotating spheres and main sense about linearity or gravitational stability.......
CONCLUSION ....strings are a lost of time and not necessary.....the spherical membran of all quantum spheres.....oscillate Ray and the universal contact between spheres give the real music of spheres....Pythagore will be happy.
CONCLUSION2 ....HIHIHI it's you who has half false hihihihi

Hi Dr Cosmic Ray.....
But the symetries Ray are linked with the volumes of the ultim fractal....thus how can you interpret the symmetries of a kissing system of spheres dear Dr Cosmic Ray....
an other idea for fun ....the lattices between spheres and the space are not the same Ray really.
The superimcompressibility of liquid seems relevant and that to differenciate the state between this said entanglement of spheres ....
It doesn't exist a real topology without the real and objective intrinsic laws of the Universal system,
closed and in evolution where the mass increases near centers of mass, the spheres.
The geometry can only explain the reality if and only if the physicality and its pure numbers and equations are inserted with the biggest rationality.
I beleive hulmbly what many confounds a maths method with a physics method.We can't interpret our Universe without a correct referential.
A simple example, I can say what the number of Stars in our Universal sphere is infinite.Thus I can derivate some suggestions BUT AND THERE IS A BUT OF COURSE indeed the number is the number of stars.
We can imagine but we must be pragmatic and rational when we speak about physics.
The Universe is the Universe Ray, it's not a play of maths creativity.
The computing and the Universe are two things differents.

Dear Steve,
Did you see the You-Tube video that Jelle recommended at Philosophy vs. Physics? The fractal rules both the discrete (your spheres, Fibonacci Integers, Fermions) and the continuous (waves, Golden Spiral, Infinity, Bosons). How does your model deal with zero or infinity? Can you use a sphere with an infinite (or zero) radius? Can you use a sphere with an infinite (or zero) rotation? If not, then your model is either not properly renormalizable, or it is not properly scale invariant. Broaden your ideas. What is the equivalent of an anti-sphere? If a sphere represents a localized-energy-packet, then what represents a non-localized-energy-packet?

p.s. - The vertices and the struts of the lattices are not the same thing. They are Brillouin Zones of each other. One type of operator (struts) represents Bosons while the other type of operator (vertices) represents Fermions. This ensures both covariant and contravariant operators as required by Relativity and the Coleman-Mandula Theorem.

For the rest, I beleive we are not on the same logic.
And even we don't speak the same language,but it's not serious.After EPR OR COPENAGHEN....
How does your model deal with zero or infinity? Waw just I see the infinity when I add or multiplicate Ray.The zero doesn't exist Ray physically speaking.SIM%PLE PROOF universe MULTIPLICATES BY 0 =0 Ray Oh My God
Can you use a sphere with an infinite (or zero) radius?Interesting this second but there it's about the special relativity Ray...you must differenciate the linear velocity and the vel. of rotations implying mass or light with 2 main different senses.If we have a 0 radius Ray it's for electromagnetism which is fractzlised by gravitational superimposings....thus for the fusion mass light.Hope you encircle this difference.Furthermore the maximum for the linearity of light is different than a rotation and its speed.
Can you use a sphere with an infinite (or zero) rotation?Interesting also...I have already answered Ray....if they don't turn thus they haven't mass simply thus you can correlate with Dark Matter or the space...ATTENTION DIFFERENT THAN LATTICES BETWEEN SPHERES...FURTHERMORE THEY EVOLUVE ALSO THESE LATTICES....
If not, then your model is either not properly renormalizable, or it is not properly scale invariant. Broaden your ideas. What is the equivalent of an anti-sphere?
An anti sphere ...yes Ray a triangle ,isocel.hihihihi And afetr we speak about renormalization of our foundamentals axioms....I have an answer...an anti sphere is the human mind HAHAHAH

Dear Ray,
Here I go giving my opinion again:
As a non-expert and speaking metaphorically, I think you may be asking for answers from idols instead of the Intelligent Cause of Creation. The use of the name God is fine with me though, with regard to additional details, I do not go beyond declaring intelligence to be the first cause of all understanding. My intent is not to define religion or religions. It is to establish that intelligence is the unexplanable first cause and is, thus far, no part of the idols put up for us by theoretical physics. I think that they are artifical obstacles put up between us and a real answer about intelligence.
Those idols, in my opinion, are like statues pretending to have fundamental causative, even intelligent, powers. A unified theory must be expected to include the explanation of our intelligence and when that day comes the idols of the mechanical ideology will crumble. The story of 'this happened and then that happened and then we happened because this and that happened first' will finally be recognized as a listing of results without explanation of cause and, most certainly, without explaining how life and finally we discern meaning from information.
The search for answers beyond our current, very limited, understanding, is bogged down in setting up more and more idols. The first idols lead to second idols which lead to third idols and so on and so on until the day finally comes when all these lifeless idols are replaced with understanding about the nature of intelligence and, even more so, intelligent life. In other words, 'until the day that mechanical theory is dropped in the manner similar to previous fallen idols'.
Other opinions are, of course, welcome. That is what lifts a forum up so that it might be a source of new, hopefully real, knowledge.

OUCH!
I'm just trying to understand the problem presented in terms of the tools I know. I'm sorry that you don't see it that way. I have explained it many times, and feel that only a few (or maybe just Lawrence) actually understand me. The experts (like Distler - yes, we had a couple of e-mail exchanges last year) don't even take the time to try to understand my perspective, and too many people don't (or won't ever) understand String Theory and Particle Physics.
My ideas may eventually overthrow physics as we think we know it, but I prefer not to assume that. How can I better define time when I still don't fully understand it myself?
I even had a possible way to incorporate thought/ consciousness/ mind/ soul/ the dream (or whatever the latest cool term is) into my model through Scale Invariance, but even FMD rejected the idea.
Oliver Wendell Holmes, Jr. said "Man's mind, once stretched by a new idea, never regains its original dimension." I guess that means I'm permanently stuck at 28 dimensions, and most everyone else is at 3 or 4.

I can't wait. It is not just anonymouse, it is many, many others. While waiting for anonymouse to reply, I will give my opinion: Socialism is the refuge, not the last refuge, that is communism, for those who are afraid. They are afraid because liberty requires us to remain vulnerable. Those who wish to give up their liberty, and be taken care of, leave themselves easy prey to the strongarm of the individual who is brutal enough to enslave them.
Those who choose liberty are choosing to provide for themselves, their families and those in need. Those who are afraid of liberty look to the powerful to take care of them and to ease their conscience by providing for those in need. Instead, the powerful deem themselves to be the most worthy and the needful to be less worthy. In the end, no matter what the socialist system is, those who rise to the top are those who are not mindful of the needy. Those who rise up are those who are brutal enough to relieve themselves of the burden of the true idealists who imagine that reason wins out over the unreasonable.
Let those who do not love liberty choose their system of control and be controlled by it. And, let those who chose liberty, take responsibility for themselves and those in need. Those in need have nothing to fear from those who, themselves, are not afraid of being vulnerable and take responsibility for themselves and others. Those who understand being vulnerable are those who are best ready to help those who are in need. That is what the 'greatest generation' in America did.
It is incredible to me that the children of the 'greatest generation' should be so irresponsible and weak so that they would choose socialism. Socialism is for those who hope that others will take over their responsibility and all responsibility and do it responsibly. Of course, that is a silly idea. How many times does the world have to laugh first, then cry, then scream at the results of giving responsibility to strongarms?
None of this, whether my opinion or someone else's opinion from a political or social point of view, has anything to do with studying the universe. Whatever we learn, it has to do with why objects change their velocities and how we discern meaning from the patterns in changes of velocity.

Dear Prof. Vedral,
Do you belive that there is, in prinicple, a possibility to mathematicaly formulate "Spontanous Emergence Mechanics"?
I would like to claim that nothing is(and can be) more familiar for the "I" of each and everyone of us - than the certainty of knowing ourselves, to be "domains" of spontanous emergences.
In that sense, I believe that anything that we percieve as something that comes up "within" us, is a tini - tiny bang.
As one expression of the cosmos - that is one and the same, in its most fundemntal level - it seems plausible to assume , that any intuition, dream, thought that just "pops" in our mind etc. are tini- tiny echos or "after shocks" of the Big Bang - from within.
So, I just had a very pleasurable spontanous intuitive bang emergence, following watching an interview with you + and due to your kind , rapid response to a previous post by yours humbly.
This is what the "bang" I exprienced, just now, "tells me" (or more accuratley "tells in me"): the mystery which we tend to believe that is "out there", "beyond" the limits of the observable universe in all dimensions - is the same as the mystery of that which is US.
So, maybe there is a hint engraved in us, as to the limitations of our ability to decipher the "underlying nature of reality" through the use of scientific method. Since, none of us ,scientists included - while expriencing spontanous mental emergences, can account for the origin of those emergeces.
These emergences "feel" as "steming" from dimensionlessness.
All that "lurks" in the dimensionless ,seems to be beyond our reach. Attempting to observe the fundementals of what IS - is like attempting to look at the back of our own minds - where there are observers that can not be observed.
I am grateful for the "thinking - fun time" that coresponding with you provides me with.
I AM very very impressed with science and its' contributions as well as with able pepole - such as you.
Have a wonderful weekend!

Dear Zeeya Merali,
What a choice, Copenhagen vs. many worlds. I do not like either of them because they make quantum mechanics just too "spooky" to use Einstein's term.
I think there is something spooky going on but it is not quantum mechanics and Heisenberg was on to it before he was "persuaded" by Bohr and Schrodinger to switch to continuously evolving waves. Heisenberg referred to his matrix mechanics in terms not of continuously evolving waves, but of particles undergoing discontinuous quantum jumps. Schrodinger eventually said matrix mechanics and his equation were equivalent mathematically. How a discontinuous representation was made equivalent to a continuous representation is a mystery to me. There was some heat between Heisenberg and Schrodinger as indicted by the following letter:
The more I think about the physical portion of Schrödinger's theory, the more repulsive I find it...What Schrödinger writes about the visualizability of his theory 'is probably not quite right,' in other words it's crap.--Heisenberg, writing to Pauli, 1926
I propose a third alternative interpretation to quantum mechanics using Heisenberg's concept of discontinuous quantum jumps which I call Digital Wave Theory (DWT). The full development can be found at www.zeno-physics.com here is the skinny (exponents goofy but somewhat readable):
1. The movement of particles must satisfy Zeno and deBroglie. The way to do this (using Heisenberg's term before he changed his mind) is: discontinuous quantum jumps, in the language of DWT this is wavelength-hopping.
2. What causes wavelength-hopping? Movement always involves inertia and gravity. So the question becomes how to associate inertia and gravity into the discontinuous quantum jumps. This is going to be done by making three assumptions. Perhaps these tenuous assumptions are better called three guesses.
3. The first wild guess: Particles when they are not seen accelerate and then decelerate moving the wavelength of the particle. Why would anyone assume something like this? The answer is so that it can be investigated to see if it produces anything interesting. It is like having a friend who is gaining weight yet no one sees him eating. We can make a wild guess that he is eating when no one is watching. Now we have something we can investigate.
4. The second guess: Particles when they move must have a minimum velocity Vo. Without this assumption the deBroglie equation would not make sense. How can a wavelength exist when there is no velocity? A stationary object with an infinite wavelength has no meaning. Waves have to move and therefore there must be a velocity. We can calculate a formula for this velocity Vo using the first wild guess.
5. The third guess: Einstein's equivalence principle is as valid on the quantum level as it is on the classical matter level. Sure, why not. With this assumption we can develop the equation for Vo in terms of G (gravitational constant), mass of the particle, and the wavelength of the particle.
6. The investigation: Take the Vo developed and combine it with deBroglies equation modified with the Lorentz transform so that it takes into account relativity. The result is the equation: Vo4 - c2Vo2 + c2m4G2/(4h2) = 0
7. It is now time to taste the pudding! The plot of the above equation gives dramatic results. It shows that particles and photons move by the same mechanism. It also shows that the speed of light is not the same for each wavelength of light. The sections that follow list features that show the ramifications of this equation. The three guesses form a coherent theory that points to a new way to understand physics (in my humble opinion).
The Basic Results of DWT:
1. Particles and photons move by wavelength-hopping.
2. Particles and photons have a minimum velocity Vo. For particles Vo is near
0 and for photons Vo is near "c".
3. Particles have a "self gravity" that can represent their energy.
4. Ordinary matter objects have a "self gravity" that can represent their
energy in terms of dark energy and dark matter.
5. Two ordinary mass objects m1 and m2 separated by a distance d have more mass
than expected. This additional "subtle" mass mx is a function of the
distance to the neighboring mass. mx = G(m1 + m2)2/(dc2)
where G is the gravitational constant and c is the maximum speed of space-
time. This subtle mass can be used to explain dark energy, dark matter and
cosmological inflation.

Re Vlakto Vedral’s point: “To have this difference between measurement and evolution is not nice and clean. There are now two ways of getting rid of the dichotomy. One is to say that there are no measurements (the Many World’s philosophy) and the other one is to say that there is no evolution (this would be the "ultra" Copenhagen view).”
Could not there be another approach? One which is a superposition of both measurement and evolution? In a poetic mood I have floated the idea of the primary equivalence of Being-Energy as the irreducible reality, which leads to visualizing Energy as a waveform, which “plicks” (i.e. presents itself as Planck-time ticks), thus providing the threshold between locality (physical actuality) and nonlocality (the realm of deep reality, undefined in space-time.)
For the informational model of cosmos the effect is of a “CPU” offering extremely high resolution, in which physical-cosmos is recreated at each plick from the Hilbert Space which is the abstract “consciousness” of All-that-is. There are interesting implications for consciousness studies, physics and metaphysics. It’s rather much to encompass in a blog reply but a published abstract and unpublished article flesh it out a bit (or byte).
A scientific journal has rejected the paper as too speculative, but of course everything that has been written about consciousness is speculative. I would welcome discussion of the idea from a physics point of view, here or at dbscriptorium@gmail.com

Dear Don,
You have an interesting perspective. Please ignore Anonymouse, Lightbringer, Cosmo D, and Frank Martin DiMeglio (All are the same person whom I call FMD - "fully mentally disturbed"). He will be jealous of your ideas because he thinks he is the only one who understands Being/ Consciousness/ Thought/ Self/ Mind/ Soul/ Dream, and the rest of us think he should be on medication... As a surgeon who donates his time to Haitian missions, I'm sure you have seen people in worse shape than FMD.
My TOE models include (and explain) scale invariance (Supersymmetry) and "spooky" action-at-a-distance (tachyons) phenomena. I think that scale invariance allows a huge (infinite?) Multiverse with many (infinite?) alternate self-similar Spacetime Universes. Perhaps our Being/ Consciousness/ Thought/ Mind/ Soul/ Dream can sample outcomes from many of these alternate Universes via self-similar Don's, Ray's, FMD's etc. and this feedback mechanism becomes the basis for our descisions in the present.
You mentioned that Hilbert space is huge, and that the cpu's needed to process this amount of information is large. In my models, Hyperspace is much larger than spacetime (My current model has 28 dimensions), and this information is stored via conserved quantum numbers (for instance, an E8 algebra has 248 components that could potentially act as bits) within Hyperspace, and then transmitted to us via tachyons.
Most physicists do not try to include "Being" within their idea of Physics. I think they consider it sufficient that Physics connects with Being through the five senses of sight, hearing, touch, taste and smell. Another fqxi physicist who is interested in this question is Edwin Eugene Klingman - please see
http://www.fqxi.org/community/forum/topic/561
Also, some of my multi-dimensional ideas are at
http://www.fqxi.org/community/forum/topic/520
but that paper does not present my scale invariance ideas, or all 28 dimensions (just the first 12 dimensions).
Have Fun and Enjoy the 4th!

Hi Anon,
1. I agree. I too have dreams and believe they are quantum mechanical as are ordinary waking thoughts. The book that got me thinking about this was "Human" by Michael Gazzaniga. All those neurons we carry around can be a large content addressable memory and the synapses are quantum mechanical look up tables. During waking the I/O is connected to the memory and we sense and act. During sleep the I/O is disconnected from the memory and noise triggers the senses and the output is inhibited. So, in both waking and sleep we have thoughts. Of course we are more than thought, but that is our tool.
2. Ray is a super contributor to this site, and I like to read his posts.
3. I wish that I were a doctor but all I do is send my prayers to those who suffer in Haiti.
4. I like to use language that is questionable and some of my posts have been removed. I am a great admirer of the physician John Crapper. He has done more good than just about any other doctor and I use his name quite frequently to keep his memory alive and prod what I see as group think in physics.
5. I would like to encourage your participation and your developing a thicker skin and I also recognize you have made yourself a "pest" as retaliation for criticism. So. lighten up, have some fun. It is just thoughts and perhaps as you and Shakespeare say just dreams (aka multiple worlds).

First, appreciation to Ray for taking seriously a physician's attempt to intrude upon a physics discussion; and for the comments of Don Limuti and Lightbringer et al. My involvement grew first from papers on medical ethics, and the realization of the need to ground ethics (and consciousness and other aspects of a medical philosophy) in physical reality. My speculations about "plicks" are not so much a reach toward a TOE, as a proposal for a shorthand way for physicians and other non-physicists to visualize and to talk about the metaphysics to which physics itself now points.
Incidentally, Don L, my proposed model seems to correlate nicely with your idea of lambda-jumps (particles moving "digitally") in your essay @ zenophysics; also with Julian Barbour's no-time theory ("End of Time", 1999). Also, it offers a philosophical approach to Wm Oren's question here (Blog topic 266: Definition: Energy) -- "But what is energy? No, really. What is it?"
For me, Being-Energy is the ultimate equivalence, the essence of the foundational nonlocal reality. Energy is inexplicable, except as the "pressure" of Being itself, for without energy there is no thing to have Being nor can any spacetime thing exist without Energy. So in a nonlocal ("ultimate reality") sense, I would strongly qualify Willton Alano's statement (today, topic/266#post_21148) that, "Additionally, no energy exists by itself. Energy is always just a property of a material body or particle".
Energy is Primal -- it is the Quality which brought the "material body or particle" into existence in the first place.
For Lightbringer (et al.), dreams fascinate me too. But may I say that newcomers will find it less confusing if each respondent chooses one particular identity for the blog, rather than a superposition of several ! :)

Don B / Donivan Bessinger

Tom,
A break from debate. Since you and I live in at least two different universes, I will post this message in this blog. Thank you for your extensive participation in debate with me and the others. Your time, expertise, and forthrightness are valuable and appreciated.

That's very gentlemanly and kind of you, James. I think you understand that I would not invest so much if what you say didn't resonate, even though I disagree. Thanks for your thoughtful criticism, as well.
