"By being on the surface, you can simulate any behavior on the inside". Well, BEM instead of FEM has been widely exploited in engineering. However, there is no denial, consideration of nature as a closed system with in principle known boundaries is elusive. The future does simply not yet exist in advance. According to all experience, any prediction has a more or less restricted horizon of probability.
. I cannot confirm that Poincaré actually showed in 1898 "that the definition of simultaneity of events at different places is only a convention". Unfortunately, the DEsynchronization by Poincaré is meanwhile called standard synchronization. Poincaré merely popularized a method that was already used by telegraphers in the middle 19th century and a teacher of Poincaré. This method is undoubtedly correct if A and B do not move relative to each other while invalid for not equally moving bodies.
A lot of paradoxical theory goes back to the unresolved problem to correctly interpret the unexpected outcome of the erroneously designed experiment by Michelson and Morley. No matter whether we consider light as photons or as electromagnetic wave, we need not the picture of a carrier that fills the empty space like something tangible we are familiar with.
I meanwhile agree with Peter in that Shtyrkov did choose a misleading terminology when he nonetheless compellingly demonstrated by means of aberration how the earth is moving in a Newtonian space. Aberration is a one-way phenomenon. Round trip experiments are more questionable.

“Is it that difficult to absorb and retain?”. Yep!! Even on New Years Day.
What you have said is all about timing. So it is not a matter of my preference for a label, that is what this is concerned with. Proper time is that time reference that is used to judge all the timings of all the relevant events. Remember, one can only make valid judgements by comparing against one reference point, and that could be any point.
SR did not confuse the situation by not fully considering that light changed speed to the local c when entering media in relative motion. It assumed that ‘ether’ had no impact on light. Which may or may not be correct. And since it was a special circumstance, there was no force, eg gravity, to affect it either. Which is correct, because it was a defined condition of this circumstance.
It has nothing to do with observation, per se. They just happen to be the source of the information.

In terms of their valuation of a phenonmenon, probably yes. Because this was just a case of 'the difference in time for light to travel one way as opposed to another, converted to distance, must equal length contraction'. There are different valuations in GR.
Of course, that is different from the question as to whether matter does alter in dimension when acted upon by a force, and whether that effect is the same for all forms of matter. Having established that, one can then assess the effect quantitatively.

Paul and Peter,
I still did not find the word Lightship in a sister string.
Concerning length contraction I do not yet at all consider acceleration.
Even Marmet confirmed
here, p.3 that the relative length of a train in motion with respect to the train at rest is shorted corresponding to Lorentz transformation. However, isn't this contraction just the imbalanced superposition of two Doppler effects? The Doppler effect describes apparent changes of length or frequency. Isn't this summary illusion the same if seen from both perspectives or twins? Therefore I consider it not physically real.

There are 3 different aspects to this:
1 Does any form of size/shape/dimension alteration occur when matter is undergoing a change in momentum due to force applied?
2 If it occurs, what is the process?
3 If it occurs, what is the valuation of it, possibly in respect of various forms of matter?
Now, Einstein, et al, said it did occur (what little was said about why, tended to change). Doppler is purely an aural/optical illusion. Forget it, in this context. I note that below your reference comments about clocks slowing, etc, gets repeated. This is nonsense. Clocks are matter. Assuming force applied causes changing momentum and some form of 'molecular disturbance', which results in some form of dimension alteration. Does anybody seriously think that that will just happen to result in the function of this entity being affected in such a way that the tick rate alters perfectly, and in every case? This is actually just a very good example which demonstates how time was misunderstood, and muddled with what they saw as a real effect on dimension. The point is simple. If bus is squashed/elongated as a result of force applied, which manifests as acceleration/de-celeration, then it will take a longer/shorter time to reach bus stop than that expected when no dimension alteration is assumed. It is about timing, not time.

I responded re the LT elsewhere. I found Marmet inconsistent in some areas. The LT formula is fine but nonsense as applied as it was not required, as light can't exceed c anyway, even without it, but it's apparent (not real) speed can. The Light ship showed that;
The lightship is adrift in the tide and wind. It emits one pulse /second. Three observers time the signal, 1. On a ship moving away, 2. On a plane approaching, 3. At rest on the shoreline.
Each observer will measure a different time period. On the ship moving away the period will be increased slightly due to it's different position each subsequent second. On the plane the period will reduce as it gets closer between each pulse. On land, it depends on the relative motion, but as the ship is relatively moving the period measured cannot be precisely one second.
Such differences will exist for all inertial frames, i.e. 'States of motion'. Paul says this is wrong, and if all observers are at the same 'point' they find the same. I expect you can see the fault there. If another plane crosses the path of the first, just before of after, so the observations are taken at in the same point, the findings will still be very different, and dependent on the motion of the observer NOT on the 'point'.
The contraction and dilation of the emitted time period found in the new frames are then directly equivalent to Doppler shifts. A flock of birds flying in line would similarly 'close up' if flying into a big gust of head wind (different inertial frame). This is certainly 'acceleration', which is, directly without even being an analogy; inertial frame transformation. Collections of matter than are incompressible however behave differently as they have to absorb the energy and emit it as heat and noise etc. Paul has not managed to visualise or rationalise this dynamic logic, and he is far from alone. Can you do so?
The LT is certainly a good approximation of the power input required at CERN to keep particles accelerating towards c in the field, so then literally represents a 'power curve', related to resistance through the condensate. The non constancy fine structure 'constant' would then be consistent with the fine structure ion flux, propagated and oscillating increasingly as the bunch accelerates. Actually the similar Yukawa ('screened Coluomb') potential seems to give a slightly more accurate curve, but that is still purely a mathematical approximation of nature as magnetohyrodynamic Navier-Stokes turbulent uncertainties must then always remain (equivalent to the aberration 'constant' which varies by similar amounts).

Peter,
What you called "two separate lists under this heading" obviously refers to part I and Part II. Also, I guess you were Anonymous. This time the signs ")" and "." were not missing. However, you did not reveal where "elsewhere" you "responded re the LT".
I would like you to either explain in detail where and why you "found Marmet inconsistent in some areas" or regret such utterances of you. To me the matter seems to be utterly important and unnecessary confusion is unwelcome.
Admittedly, I am still having sometimes difficulties to understand what you and Paul Reed meant. The English of Paul Marmet is mostly more persuading to me. It's not just because you first wrote Light ship and then lightship and perhaps ";" instead of ":". Why is the LT formula fine and why is it nonsense? I do not understand the logic of your whole sentence where you seem to argue that LT is not required because light cannot exceed c.
You introduced the perhaps self-explaining term lightship as a drift in the tide and wind. My dictionary explains three meanings of tide. Only the first one might apply: the regular change of the level of the sea.
Sorry, you meant perhaps a common reference (4) moving relative to 1, 2, and 3.
If I understood you correctly, the velocities of 1 and 2 refer to 3. A common signal is emitted by (4).
To me, it does not matter whether the signals are transferred by sound or by light in (4). I do not see any acceleration. The Doppler effect is of course different for ship, plane, and shoreline.
My answer to Paul's caveat is also simple. The Doppler effect changes its sign at the moment when two moving relative to each other points arrive at and then move away from the same position.

Point was about motion, because relative motion is changing spatial point relationship.
Leaving aside dimension/shape alteration, then all we have is an illusion. So, what is driving this is dimension/shape alteration, apart from the fact that they said so! Whether they were right is a different matter, both logically, and in terms of the quantification of the effect.
The illusion is explained as follows. So can we please forget about this phenomenon and move on to examine what is really happening, ie is matter ‘elastic’ in some way, and by how much, and how does light (as in gathering and conveyance of realisable images) work.
The illusion:
Light is the information medium in an experience based on sight. As light travels, there is a delay between the existence of a state and its perception. That delay will vary as a function of the individual spaces involved, and the speed with which the light travelled in each experience. Whilst the perceived order of sequence will never vary, assuming that light has a reasonable degree of constancy of movement (ie is not fundamentally erratic).
The perceived rate of change of a sequence will remain the same, so long as the on-going relative spatial position remains constant amongst everything involved. Because, while the value of the delay is different depending on each individual space, it remains constant. However, when relative individual space is altering, then the perceived rate of change alters, because the delay is ever increasing (or decreasing) at a rate which depends on the rate at which individual spaces are altering. It is a perceptual illusion. The intrinsic rate of change (duration, in reality) in the sequence being experienced does not alter, either in order to create this effect, or as a consequence of this effect being realised.

The Lightship is indeed the emitter, wrt which 1,2, and 3 are in motion. It is a 'floating lighthouse'. I forgot there is little tidal flow in the Baltic. This one moves with the flow of the tidal currents, so moves wrt the observer ashore. This simply helps show that all frames are arbitrary and relative. The point is that the emitted 'time' (durations) in frame 4 has changed when measured in all other frames. This is the true meaning of 'Proper Time'. Only the measurements in the frame of the lightship will give the same, emitted, duration (rate of 'change').
Paul. You seem to have a penchant for throwing out babies with the bathwater. You wish to write off and forget this effect as just an 'illusion.' If you are correct, then our whole experience is an illusion.
The point is that this 'illusion' is all we ever, and can ever see. It is 100% of the 'observation' that Einstein and we are trying to explain. To ignore it is like Sherlock Holmes saying "ignore that smoking gun, it's only reflected light, we need to find where the bullet came from!" The term 'seeing the wood for the trees' comes to mind. The 'intrinsic rate of change' DOES change, physically, for an observer in a different state of motion. Apparent time is based on light speed, so changing one between frames (physically real matter in motion) changes the other. If the light were a stream of machine gun bullets they WOULD arrive at varying rates subject to relative frame motion.
Each bullet is however more rigidly made up than the string, so would only contract or dilate a tiny amount on acceleration between frames, unlike light.
The implications are enormous. You seems to grasp then keep loosing this before applying it.
Eckard; The LT is not then required as applied, because light does not exceed c, because it always changes speed when moving between frames to the new LOCAL c. Remember, frames are real physical entities consisting of matter in relative motion (even in a near vacuum). In a perfect vacuum it never changes speed.
EWhen it meets any matter (inc. all lenses) it is immediately absorbed and if re-emitted is emitted at the local c/n (so changes speed). Any change of speed is scientifically termed 'acceleration.'
This is what Marmet didn't realise, so is why he could not complete the solution.
If your car accelerates, the light entering it from the front must decelerate more ('accelerate') because it will still be found doing c wrt your car when re-emitted by the glass. This is what physically produces the Doppler shift. (lambda and f change to conserve new c).
This is far from mainstream, and lodged firmly with Occam.
Is the simple logic yet becoming visible?

Peter,
SR deals with constant velocities. Your tide alternates up and down. Perhaps it is not the best model.
Once again, I dislike you blaming Marmet for allegedly being unable to realize that a wave "always changes speed when moving between frames". In my understanding, any wave propagates within a belonging frame of reference with a speed c that is a characteristic constant for this medium. During this movement with constant speed, it does not move from one frame to an other one.
Incidentally, are you correct when arguing "Any change of speed is scientifically termed 'acceleration'"? Lossless reflection does not accelerate a wave when it just changes the sign of its speed.
The naturally belonging frame of reference (0) is of course not the only one from which the wave can be considered. The wave can also be expressed with respect to a mirror (1) moving with v relative to (0). Marmet dealt with "Switching between Frames of Reference". While the measured velocity of light is c-v in one direction and c+v in the other, as an experimental fact, it is equal to c wrt an absolute frame in space. Moreover it is apparently constant in all frames using proper values and correct (non Einsteinian) clock synchronization. GPS takes into account: The velocity of light from SF to NY is different from the velocity from NY to SF due to rotation of earth.

Our whole experience is an illusion only if we do not understand the basic dynamics of what is happening. The point is not “that this 'illusion' is all we ever, and can ever see”. Because if it is, and it could be, then what exactly is all the argument about?
The point is that Einstein, et al, postulated another variable, ie elasticity-spatial dimension change when force is applied, which also causes changing velocity. They may have been wrong to do so, but that is the variable. Which to further complicate its investigation, has been incorrectly morphed into an effect of time.
There is no such thing as Proper and not-Proper Time. There is only timing. That is: 1) at any given point in time x y z existed, 2) x does y at a frequency which involves the change from state f to g occurring in 2t, g to h 5t, etc, etc.
And, just to repeat another point. To be comparable, or to properly compare, then that which is being compared must have a value which is established wrt the same, ie only one, reference point.

Yes SR involves only constant velocities. Actually, uniform rectilinear and non-rotary motion. Light rays travel in straight lines at a constant speed, and there is no alteration in the dimension of matter. And mathematics which presumes fixedness applies. Why? Because there is no force, ie gravity. That is what is ‘special’ about this circumstance.
Yes a wave has a frequency, and that frequency is in no way affected by ‘frames’, etc. The issue here is merely the process of quantifying it.
Yes, as said above, any frame can be chosen, some being more practical than others, but once chosen, that is the only frame usable.

"Marmet dealt with "Switching between Frames of Reference." and so did I.
(and so did SR via the LT).
If, as with the exclusion principle, no 'point' or particle of mass can be in more than one state of motion at any instant in time, which is what I propose, then the only decision left to make is how many particles, or how 'big' a chunk of space, can represent a single exclusive inertial frame in a local background frame (yet with smaller discrete 'spaces s' moving within each).
I suggest they are scale invariant. In which case we have simple physical Occam inertial frames. i.e. a train, and your car. I found it works perfectly and all the paradoxes evaporate. Moving frames within frames does however seem impossible to communicate as a concept. I can't even get Paul to find it via 'Proper Time', and he's now 'improving physics' by renaming it!
I'm under pressure on three papers and a video, but need to go away and re-think how to communicate it successfully. Thanks for trying.

No, I am trying to get people to understand what the phenomenon is that they refer to as time, and how this is different from, and what constitutes, timing.
Here is a simple experiment, especially for a Sunday. Go outside. What do you perceive? Bird flying, dog barking, leaf changing colour, house decaying. Etc, etc, etc. What is actually happening (and I prefer that to philosophy!) is change. Physically existent states are changing. That has a substance (ie what changed) and a frequency, ie the rate at which it did so. The latter is erroneously labelled as time. It is a real phenomenon, but it it the freqency at which any given sequence of change occurs. For the puposes of quantifying this, or comparing disparate types, we have a duration measuring system, which is timing.

Is simultaneity of events at different places only a convention? No. Poincaré was perhaps led to this view by reasons that require reconsideration. Let me consider a duel between Abel and Bebel. Abel was hit first although their guns fired exactly simultaneously and the distance between them was equal at that moment. Why?
Abel was at rest wrt ground.
Possibility a) Immediately after they shot, Bebel run away from Abel. So he increased the time of flight for Abel's bullet.
Possibility b) Until they shot, Bebel and his gun moved toward Abel. So the velocity of his bullet wrt Abel was increased.
Obviously, the simple description of a system by states just at a present moment is incomplete. I learned that the initial conditions for unilateral Laplace transformation must include not just the values of variables at the very moment zero but also all of its infinitely many derivatives. Conversely, an analysis of measure data cannot be adequately based on hidden Markov models for a single moment which omit any memory.
That's my objection against naive presentism.

There are different simultaneities :
1. The simultaneity as it "appears" in our consciousness, this is an apparent simultaneity and is the base of your perception of reality, it has nothing to do with:
2. absolute simultaneity (, this is the simultaneity which is not observable to us, because it is happening at a unique moment in our causal universe like explained in the idea of the so called "block universe" (a slice with the dimension of the Planck time). Every human being being on a different coordinate in this slice is experiencing a different "reality" caused by the signals received from his senses (these "realities are slightly different when two persons observers are near to each other but can differ a lot when the distance is growing.
3. Total Simultaneity. This is the (what i call) dimension that is NON CAUSAL. It id found behind the minimum length that we can observe and where causality is no longer "real" which means that there is no place for both the event and the cause, untill now this limit as we are know of is the Planck length and time. beyond this limits the slices of absolute simultaneity are all together, a slice becomes a point becomes a probability, and so all the probabilities of all the paralel universes are united together, can a probability be measured or observed ? no. see also

Paul,
Ubiquitous simultaneity means symmetry: Any two events A and B at different locations may mutually be perceived or may influence each other via the same medium after the same delay provided the delays are corrected for the time of flight.
So called Einstein synchronization, which was introduced by Poincaré and practically used before with stationary positions of A and B, is not in general symmetrical because it assumes a signal that goes first from A to B and than return from B to A. The assumed reflection ABA is not symmetrical. For instance in case of steadily growing distance between A and B, the return path BA has meanwhile grown longer than the path AB. It is justified to reject Einstein synchronization because it does not correctly synchronize two moving wrt each other clocks. On the contrary, it desynchronizes.

1 “The simultaneity as it "appears" in our consciousness”.
I do not understand what this can mean. On the assumption that any triggering of consciousness in any individual takes the same amount of time, then this event can be equated to the receipt of information at the sensory organ, or alternatively (again assuming identical delays in all individuals) the articulation of what they perceived (or at least the pressing of a stop watch!). If this phrase has anything to do with interpretation of received information, then I am not interested because that involves physiology, sociology, ec, etc, ie every aspect involved in the processing of information received.
2 “absolute simultaneity (, this is the simultaneity which is not observable to us, because it is happening at a unique moment in our causal universe…”
I do not understand what this can be either. What two, or more, ‘events’ are occurring at the same time (ie simultaneously). I think this means all existent states which occurred at any given point in time (given the phrase “slice of”)? The reality is not different, the representation of it might have altered in travelling. It is not “signals from his senses”. Again that is about the processing of received information. It is ‘signals’ (representations) to his senses.
3 “Total Simultaneity”
Again, what can this be?
Reality occurs (exists). Then another (ie it appears to us the first has changed). Each state of existence instigates representations of it (light, heat, noise). We receive the latter, and then process it. But it could have been altered depending on circumstances of travel, and the timing of receipt will depend on distance for travel. That’s it. Why all this complexity, which does not appear to have any correspondence with reality anyway?

As stated some weeks back, the A & B example was nonsense. Events around A were all deemed to be the same. As so with B. Only differences A to B were considered. We then had local time and common time. If one understands the basic dynamics of reality, then this is obviously not correct. Each entity is different. There is therefore a difference in the time delay between event (existence) and receipt of information about that. Einstein glossed over this with “immediate proximity”. Which immediately invokes the question: just precisely when is immediate no longer immediate!
The paths did not alter, it was expected that light would differ in time taken to travel one way as opposed to the other. But it did not. Apparently!! And the rest is history as they say. The upshot from this being the presumption that matter has elasticity. That was then used, in a really poor argument, to assert that this elasticity manifests itself in clocks as a perfect alteration in tick rate! The fact that this consequence is unlikely to occur, along with the fact that a clock is a mechanism for timing, it is not time, was to no avail. Never let facts get in the way of a good story!

Nonsense is an impolite but in case of Einsteinian ABA synchronization justified judgment. Sorry, I do not recall you having said something enlightening about A&B. May I search for the word nonsense?
If, as Marmet revealed, the experiment by M&M was inconclusive from the very beginning, then I see no reason any more for maintaining the introduced (iIrc by Lorentz) notion local time. In principle, we did not even need different times on earth as we also accept that January is hot in Australia.
I see ubiquitous time, Wilhelmus wrote absolute simultaneity, a logical while of course not observable consequence of the only indispensable belief in mutual causality.
You mentioned the wrong idea that an infinitely extended rigid rod could transfer a motion faster than light. Well, Newtonian mechanics must not be carelessly applied in this case. You are right: Any real rod is elastic to some extent. Otherwise it could not even convey sound.

Anyway, for some strange reason whilst reading Einstein last year a memory came back to me. 40 odd years ago, when trying to figure out how reality worked, in amongst all the arguments about objective/subjective of the late 60s, I thought I'd have a look at Relativity. Suddenly I remembered how I'd sat there all those years ago, with a pad, and drew spots representing A & B, etc, etc. And then thinking, well this seems daft. Because everything is seperate. It is just that the things around A are nearby, and not near B, and vice-versa. Assumed I'd obviously missed something, and put the book back!
As said in the past, I can't pretend to understand Marmet, the M&M experiment, etc. Whether it was right or wrong to do so, both in the sense of a) did M&M prove that, b) is it correct anyway, the conclusion drawn was that matter has an elasticity. Specifically, it alters dimension in the direction of motion. This the impacts on space and timing.
There is no time in reality, local or otherwise. It is a sequence of existent states. Which mostly to us appear like nothing has happened (because the change is so slight and/or quick that we do not perceive it), or there has been a change to some thing (because we still do not perceive all the change that has occurred, but notice some). The rate at which all these changes occur can be timed.
Indeed, "we do not even need different times on earth" (though you give a slightly different example). Because one can express change, and even the frequency of it, without using the words time and timing. For example, while I listened to the afternoon play, it rained n mms. This reveals what the phenomenon that we refer to as time is all about, in reality. It is the frequency with which change occurs (in this case a play being performed and rain falling). While timing, is the comparison of such frequencies against a standard measure of frequency. So we would say, the play lasted from a to b, a total duration of an hour. Similarly for the rain. Furthermore, if you think about it, assuming you were wearing a crystal watch, then what one is really saying is that the event lasted from crystal oscillation number x (which is deignated by the read out on the hands) through n million oscillations, to oscillation number x. Time is the frequency with which an existent state is superseded by the next. Timing, is the activity of measuring that attribute of change.
"You mentioned the wrong idea that an infinitely extended rigid rod could transfer a motion faster than light" Did I? I thought I just said something about the expectation that light would travel quicker in one direction (between A & B) than the other (because of the motion of the earth). But (supposedly) the M&M experiment gave a null result. Which then led to the presumption of elasticity in matter.
"You are right: Any real rod is elastic to some extent. Otherwise it could not even convey sound". Interesting concept re sound. It is not me saying it, I do not know whether it is true or not. I just keep drawing attention to the fact that this is the variable driving the theory. But they, and everybody else, seems to have lost sight of this, and replaced it with the concept that time changes. Whereas, both space and time are consequences. A squashed (contracted) bus has further (space) to travel, and will take longer (timing)than expected if this elasticity is not acounted for. Space and time(or more precisely, timing) are not altering, as such. Matter is (supposedly). Space and timing being consequences of matter and changes thereto.

1. Simultaneity "as it appears in our consciousness", is perhaps not a good choice of words. I mean with it one moment in the flow of signals that arrive via our senses, this moment is not the same as the reality moment because it is already 200 milliseconds in the past, as we perceive it it does not mean that we interpreted it, it is just one photograph of the film that we are receiving.
2.absolute simultaneity is larger as the observed simultaneity because the observed simultaneity has the borders of distance and light speed, it is caught in a cone, beyond this cone simultaneity continues at the specific time moment (slice of the block universe) but is not observable for a specific observer. This absolute simultaneity is only valid for our "own" universe. The sequences of the slices make time emerge, and create the causal time lines that we experience as "reality", past , present and future.
3. Total simultaneity represents not only our Universe but all the other possible and non possible paralel and multi universes. A slice (sequence) of this simultaneity is much more difficult to imagine, but when you imagine that the slice of the absolute simultaneity becomes a point in the total simultaneity, that is why I called it another "dimension",(direction), all the sequences (slices) of this total simultaneity are probabilities and existing probabilities of the pasts and the futures.

"(supposedly) the M&M experiment gave a null result. Which then led to the presumption of elasticity in matter." I see several mistakes:
i) The M&M experiment and all its newer variants did not supposedly but obviously give a null result. Marmet did not question this fact. However, he revealed that the expected result was illusory based on neglect of Bradley's effect.
ii) In order to explain this revealed now as illusory discrepancy between the correct result and the revealed by Marmet wrong expectation, experts like FitzGerald, Lodge, Larmor, and Lorentz concluded that there must be some sort of length contraction and time dilution. Physics still suffers from this mistake.
iii) They even suggested a local time.
iv) Such eventually relativistic ideas were mingled with the similar real phenomenon of Doppler effect which causes corresponding but merely apparent changes, cf. Woldemar Vogt.
v) So called relativistic length contraction must also not be confused with elastic change of length.

1 That’s OK, I did try to figure out what the words probably meant. “this moment is not the same as the reality moment “. Correct. Though personally, I would forget the concept of consciousness, because that is a ‘whole new ball game’. The subject here is physical reality, so receipt of information at sensory detection system (in simple language-eye, ear!) seems a more sensible point in time to refer to. Even if in practice it is very difficult to determine. The point being that the information received is then processed. We really want the raw information, but it can only be extrapolated from individually articulated perceptions. So an understanding of that processing is needed, but in the case of investigating physical reality, only so reverse engineering can be effected. There is then another piece of reverse engineering to carry out, which is the province of physical reality. Because that information received is only a representation of reality, it is dependent upon certain physical phenomena carrying out a function of gathering and conveying it (in simple language again-whatever existed interacted with photons, and instigated other effects, which we then sense). So, as you say the two moments occur at a different time, or put the other way around, there is a delay whilst the representation created travels to us.
2 I still cannot understand what this can refer to. Simultaneity of what? There is reality. Separately, there is the sensing of it (observation being one form thereof). By definition, what is possible to sense is highly likely to be different from what is available to be sensed (which is reality). Because the sensory systems of all organisms are limited, the process relies on representations of reality, and some existence is outside the capability of the sensory detection systems (ie too far away, too small, etc).
“This absolute simultaneity is only valid for our "own" universe”. There is only ‘our universe’, we can know of no other. We can only know what we can know, which is a function of sensory detection. One then has to resort to hypothesis, or just belief.
“The sequences of the slices make time emerge, and create the causal time lines that we experience as "reality", past , present and future”. I will leave ‘sequences of the slices’. Time does not emerge, it is the frequency with which existent states turnover. Remember one can only have on at a time (within any given sequence, which might relate to one elementary particle or the entirety of existence, at any given point in time). In reality, there is only present (existence). In the sensing thereof, as said above, there is another timeline, because one is now dealing with representations of reality, though these are existent in themselves.
3 There is only the logical possibility of another ‘universe’. And we certainly cannot know it, or slice it, or whatever.

We are back here to an exchange that we have had at least once before.
What the M&M experiment really proved, or did not prove, I do not know. And anyway, the reason for a presumption is irrelevant, in the sense that it exists and is utilised to create an hypothesis. The presumption in question here being the elasticity of matter (specifically alteration in dimension in direction of travel) which is ‘revealed’ by the application of force (eg gravity), which at the same time alters momentum. In those early years, various (rather thin) explanations were put forward to account for it.
Now, whether this effect (known colloquially as length contraction, because there are virtually no references to the reverse process) occurs is something that needs investigation, in itself. The history, etc, is another matter.
The accompanying effect (colloquially known as time dilution) can be dismissed immediately. What happened here is that the elasticity effect was replaced by the consequences. I suspect because (and this is expressed) the concept of dimension alteration was not understood/believed in. So the consequential effect on space and time took precedence. Note the effects are all of the same order. Time in particular became a surrogate for elasticity. Times do alter, so this is easier to use as the basis for an explanation.
Except that the phenomenon being alluded to is timing. Because the other way to get to the same conclusion, ie that it is all about elasticity (which may or may not actually occur, but this is the driving force of the hypothesis). Is to establish what time actually is. At which point one realises that it is not a dimension of reality, but the rate at which reality changes. It is timing that is ‘altering’, in so far as given matter with a different dimension to that which it had, timings will be different. All this confusion was reified into space-time, which is a representation of the dynamics of reality which does not occur. Reality, ie that which exists at any point in time, only having the characteristic of spatial direction.
And yes. Another confusion revolves around the Doppler effect. I have a couple of paras on this, which I have posted many times. Essentially, this gives the perceptual illusion of change, ie it is not actually occurring, because of the variance in delay as relative spatial position alters with movement.
This boils down to the hypothesis of Relativity is based on elasticity in matter, which needs to be proven. Space-time is an incorrect model of reality.

Paul, about "the conception of consciousness" : see also José Martinez (http://linkd.in/vZwSGQ) and http://linkd.in/AsqEUK, about nonlinearity in the input-output sequences in our brain. José claims : "Consciousness is nothing else then a resonant process between well synchronised neural ensembles and an "external" field. Such an external field may be driving force of evolution till make its perfect receptor "us" ", he continues : "We are nothing else than bad "antenna's" able to detect and to decode a poorly wifi connection coming from nature" :).
about 2: absolute simultaneity. "Present antime exist simultaneously in a "BLOCK UNIVERSE" and our perception of time is just an illusion" (in http://www.fqxi.org:comunity:articles/display/135). My own problem with this article is that it is said that the wave function collapses , but then it collapses already before we are aware that it is an event.
The only explanation I could think of is:
Our consciousness is not only an antenna to receive signals from the past but also an antenna that emits signals into the past, or even better our consciousness is entangled with all the sequences absolute simultaneity of our causal universe, in the way of entanglement of two particles in quantum theory, but here the entanglement is timeless, like the entanglement of two particles is timeless too, but only in a "NOW" way. This idea is congruent with my idea of consciousness and Total Simultaneity and the essay I wrote in 2011. It also explains your last question about paralel universes, they are just time-lines that are not observed, not collapsed, not entangled with our consciousnes, but they are possibillities just to be "observed" from other consciousnesses, even those who have different ways of observing as we have.
awaiting your valued critics

As said previously. Apart from the fact that I probably cannot understand this. As a matter of principle, there is no need to try to. How the brain works, how sensory organs work, how cultural background impacts, etc, are ‘something else’. We need to know this process. But only because ultimately we can only access the information received via articulated perceptions (ie the outcome of the process). To understand physical reality, we need to know that information received. And even the, reverse engineer it from representation to reality. But the process being reverse engineered is a physical process. Apart from which I would suggest that for the most part, consciousness, etc will not intrude in the ‘lab’ situation. What is more problematical is flawed hypotheses.
It is not a Block Universe. Sorry I cannot remember what the flaw was with this concept, I did look at it when people thought this was what I was saying. But your comment about wave-function collapse is correct. This cannot happen, given how reality is constituted. Not only has existence already occurred, but what the information we receive, later, is not reality!
You don’t need an “explanation”. The whole concept is incorrect. It is contradictory to the way reality ‘works’. Here is reality: a b c d e f g. These are existent states in a sequence (ie each is a ‘now’ at the time it occurred). When in existence that state reacts with the then existent state of other phenomenon. So there is light a, light b, etc, noise a, noise b, heat a, heat b, etc. Etc, etc. We receive the latter. Which has to travel from the spatial position of a b c etc when they occurred, to organism. There is a delay, the possibility of distortion during travel, and it is only a representation of what actually occurred. And remember, that for each a b c d, etc, there are many existent representations of that generated in each mode of sensory detection.

Paul, I use the image of "Block" universe only for explaining, as all physics is only a way to explain the unknown, it is for me just a tool to make my thoughts more touchable, a model. This model however helps also to think a little further.
My present problem is where is the difference between "observation" and "interaction". (could be a new thread). If you take the idea of observation it is coupled to an observer with his own limited aeea of observation. When observation is the cause of the collapse of the wave function the area of collapse is determined. (The reverse engeneering to the ORIG point is then also a very important task for us)
However when interaction is the cause of collapse of the wave function then I do not see any wave function any more because everything is "interacting", so the double slit experiment as a matter of fact could not exist ? But the particles pass by the double slit as waves (probabilities) so the slit is not "interacting" with these waves/particles. When there is one slit the wave becomes a particle , so is collapsed, so one slit is is an interaction. I just cannot understand it. Does this mean that when there is a choice to be made there is no interaction ? Does this mean that observation is a definite decision (of a choice) ? Conscious observation is in this way becomes a choice MADE definitive.
But here I arrive at the time problem, if I folow this reasonment I HAVE to use Total Simultaneity to explain that the choice is made a minimum of 200 milliseconds before the actual awareness (Triangle : ORIG (event) - Consciousness - Total Simultaneity. Consciousness antenna (timeless) touches in Total Simultaneity (non causal) the ORIG, and is the cause of the event as we are aware of.
think free
and thank you for the brain-storm

“I use the image of "Block" universe only for explaining, as all physics is only a way to explain the unknown..”
Er yes, but if there is a flaw in it, ie it does not fundamentally correspond with reality, then it’s not of much use as a model/tool.
“My present problem is where is the difference between "observation" and "interaction".
‘Observation’ is the processing of a representation of reality via the optical sensory system, which is instigated as a result of an ‘interaction’ between photons and the reality. Hearing is…..etc, etc.
So, assuming wave-function is a reality (ie it is existent), then we do not cause its ‘collapse’ anyway. Upon receipt at any given sensory system, the representation of reality being received ceases. There being many others of the same reality. Some being received by other organisms, some being ‘received’ (ie colliding with) inanimate objects, some travelling into space.
“But here I arrive at the time problem”. Only if one has a flawed conception as to how reality is constituted.
“and thank you for the brain-storm”
This is OK Wilhemus. Whilst I endeavour to limit my time involved in this ( I am now going to do some tiling), I welcome the responses, and from ‘different angles’, and will always respond. As whilst it involves me repeating stuff, I always type a new set of words, and it makes me re-check what I am saying. And contrary to what some seem to think, I do not presume I am correct. As with anybody else, one would prefer to be so. But ultimately I don’t care, as I have no vested interest, it just being an intellectual current interest.
