| Roger Penrose longs for Moving Dimensions Theory. Where he falls short in the following discussion is where he states, "the future is out there." The future is not out there. But where Penrose steers close is in acknowledging, "I think we need a new way to look at time, not either Quantum Mechanics or Relativity." MD Theory offers this new way. Time is an emergent phenomena. Time happens because a fourth dimension is expanding relative to the three spatial dimensions. Moving Dimensions Theory offers a new way of looking at time underlying both QM and SR a phenoma that emerges from the MD Theory: THE FOURTH DIMENSION IS EXPANDING AT A RATE OF C RELATIVE TO THE THREE SPATIAL DIMENSIONS IN QUANTIZED UNITS OF THE PLANCK LENGTH, GIVING RISE TO TIME AND ALL QUANTUM MECHANICAL AND RELATIVISTIC PHENOMENA. [Only registered users see links. ] Penrose's mistaken view of "the future being out there" arises because of physicists misleadingly labeling "time" the fourth dimension, thus implying that just as we can move anywhere in the three spatial dimensions, such as up and down and back again, so too can we move anywhere in the time dimension, to the past, the future, and back again, implying that both the past and future must exist, as sure as New York and Los Angeles. But time is not so much the fourth dimension as it is an emergent phenomena that arises because a fourth dimension is expanding at the rate of c relative to the three spatial dimensions in a spherically symmetric manner in units of the Planck length. Dr. E has added to the following dialogue with Roger Penrose, showing how Moving Dimensions Theory can unify the concept of time in SR and QM-in fact all phenomena in SR and QM might be accounted for by Moving Dimensions Theory. The original dialogue may be found here: [Only registered users see links. ] Roger Penrose : "I think there's always something paradoxical about the way we seem to perceive time to pass and the way physics describes time." Dr. E: Moving Dimensions Theory alleviates this paradox by viewing time as an emergent phenomena-something that arises because the fourth dimension is expanding relative to the three stationary spatial dimensions. Roger Penrose : Space-time is certainly different stuff from space because its 4 dimensional instead of 3-D (RP larfs!) which is a big diff. Time really has to be brought into the picture; this one thing which is space/time. Physicist : Just imagine what this might be like: 3-D space implies a volume, and you can move any where in that volume. Once you add time as a 4th dimension, another axis, then this block of space/time would contain within it past, present and future, all at once. Time is frozen, all times exist together; so just as you can say "over here, over there" in 3-D space, you can talk about "over then", in 4-D space/time. Roger Penrose : It's a way of looking at things if you like which physically we seem to be forced into. I say physically from the point of view of what the theory of rel. tells us. And Relativity is remarkably well tested, I mean, 14 places of decimal, it's just incredible. So we know that this theory does describe the universe to an extraordinarily precise degree, so we have to take it seriously. And that theory tells us that we have to regard space and time as one thing, it's all out there, it's one thing. In the same sense that space is out there, time is out there. Dr. E: No-the past and future are not out there. There is indeed a fourth dimension, and that dimension is expanding relative to the three spatial dimensions at the rate of c in units of the Planck length. We perceive time-the past and the future-as events and dreams in our memories and minds, based on the interaction of the fourth expanding dimension with the three stationary dimensions. Narrator : Like the Medieval God's-view of time, Einstein's physics says that the future is already out there. The moments of our lives are just waiting for us to step into them. Roger Penrose : But there's no more problem about the future being out there than saying that space is out there. You say, "Mars is out there", but why is that more comprehensible than saying "next week is out there"? It's just as far away in a certain sense. Physicist : If you take this block of 4-D space/time literally, it means you have to abandon free will. It means not only is the future pre-ordained, but its already there, its already happened. There's no point in making any decisions, whatever you do has already happened. If I choose to drop this stone into a pond, I think of it being my own free choice, but of course in 4-D space/time I had no choice in dropping the stone ; the splash is already there in the future and so we lose all free will. If time travel was possible, you can imagine people coming back from the future to visit us; its no good us saying, "you cant exist - you haven't happened yet".They've come from a time which they consider to be their 'now' and for them we're in their path. Roger Penrose : So this means that in a sense, the present past and future are out there, and that also gives us a very deterministic view of the world. We have no control of what happens in the future because its all laid out. I think the trouble that people have with this idea is that you think the future is under your control, to some degree, and so this means that if the future's laid out then in a sense its not under your control. Physicist : Personally I'm very uncomfortable about the block universe idea. Now this may be just a gut feeling or just irrational, but can't accept the future's already 'out there'. I don't accept that I don't have any free will. Roger Penrose : I think there is a positive side to this picture of space and time being laid out there as 4 dimensions, because it tells you that all times are there once and it can affect the way one thinks about people who have died. I mean, I remember thinking in this kind of way when my mother died. In some sense she was still there because her existence is still out there in space/time although in our time she is not alive. A colleague of mine had a son who died in tragic circumstances and I presented this idea to him and it helped his understanding also. This was before I heard that Einstein had a colleague died and he wrote to the man's wife that Bessa was still out there, and that somehow this was reassuring. I certainly think this way often, that space/time is laid out and that things in the past and things in the future are out there still. Narrator : But almost at the same time that Relativity was gaining universal acceptance a radically different picture of the universe was emerging. Physicist : The way out if you don't want to accept the block universe idea is quantum mechanics. Now, Quantum Mechanics is the second great discovery of the 20th century physics and that states that the future isn't predetermined and preordained. Narrator : Quantum Mechanics was born out of a series of experiments whose results even today have no satisfactory explanation. Relativity works at the large scale where it provides exact predictions as to what will happen next. But when physicists started looking down at the atomic and sub-atomic level, the familiar laws failed. At this level, there were no certainties, only probabilities. How can the future of the universe be already out there if the future of a single molecule is so utterly unpredictable? Dr. E: The future of the universe is not already out there. Both quantum mechanics and relativity derive from the same underlying physical reality of a fourth dimension expanding relative to three spatial dimensions at the rate of c in units of the Planck length. The wave-particle duality of matter comes from the inherent non-locality of any matter at a point in the expanding dimension, which would appear as photons expanding in a spherically symmetric manner at the rate of c. The constant speed of light also comes from the physical reality of the fourth dimension expanding relative to the three stationary spatial dimensions. No matter how fast the emitter is traveling, the expanding dimension yet carries the photon at the rate of c. Physicist : Before we look to see what the atom is doing, not only is there a gap in our knowledge, the atom itself has not decided what to do. It had an infinite number of choices to make, it will be doing all those choices all at once, and its only when we look to see what is happening do we force it to make a choice. In Quantum Mechanics the future is not determined, and so Quantum Mechanics in a sense rescues us and rescues free will. Roger Penrose : In a sense you don't have the future laid out in Quantum Mechanics So Quantum Mechanics. is basically different in the way we look at it. You do have this indeterminacy about the future and a necessary feature of this is its incompatibility with Special Relativity. So we have these 2 great theories, both of which are extremely accurate, tell us something about how the world operates, something very insightful and profound and accurate, but they're incompatible with each other. So there's no doubt there's something missing here. How important it is to how we 'feel' the passage of time is I think very important. Dr. E: But QM and SR perfectly compatible theories. In SR there is no certain future-that is a byproduct of mistakenly looking at time as a fourth dimension on equal footing with the three spatial dimensions. The passage of time happens because of matter interacting with a dimension that is expanding relative to the three spatial dimensions. And all quantum mechanical and relativistic effects may be traced back to Moving Dimensions Theory. Narrator: The tragedy of modern physics is that it explains so much of the objective universe but at the cost of what we subjectively feel; about our conscious free will and our feeling that time does flow. Faun Flynn: I very much think there's a flow to time. If you consider what music would be like if there was no flow to time. You couldn't have music if you didn't have memory, or if you didn't have an expectation generated by that memory. You'd have an isolated note in the 'now'. Music unfolds in time in such a way that we have a memory of what we've heard, and this memory conditions to what we expect. This of course is something that everybody is familiar with, because if you hear ( 7 note scale played on piano) you have a very strong expectation that the next note will be (plays final octave note of scale) . Music is a distillation or a side-effect of that mental faculty we employ to perceive time, and things changing in time. Roger Penrose : The question of the passage of time is something the scientists have rather set aside, and taking the view that its not really physics, it's a subjective issue; and subjective questions are not part of science. Now when you start talking about phenomena like one's own perception of the passage of time, then that is a subjective thing. And that's almost a taboo subject for science because it's subjective. The physical world at least according to Relativity, is out there, and there is no flow of time, it's just there; whereas our feeling (we have this feeling of the passage of time) are intimately connected to our perceptions. Dr. E: Indeed scientists too often choose their battles selfishly, thereby solving problems by saying that they do not need to be solved, while simultaneously concentrating on obscure theories, spending millions on building empty temples for the herd. The physical future is not out there according to relativity. The passage of time is the result of the propagation of energy. The aging of cells, the oscillations of a quartz crystal, the unwinding of a clock spring, the swing of a pendulum-all of these have to do with the exchange of photons and thus the propagation of energy. And energy propagates at the constant rate of c throughout the universe because the fourth dimension, which carries matter that we perceive as photons, is expanding at the rate of c relative to the three spatial dimensions, in units of the Planck length. Physicist : We have this subjective feeling, that time goes by, but physicists would argue this is just an illusion. Roger Penrose : Yes I think physicists would agree that the feeling of time passing is simply an illusion, something that is not real. It has something to do with our perceptions. Dr. E: The passage of time is real. Time's arrow, or entropy, or the second law of thermodynamics are all explained by Moving Dimensions Theory. Because a fourth dimension is expanding at the rate of c in a spherically symmetric manner, all particles have a probability of being displaced in a spherically symmetric manner. Thus any two particles close to each other will wander apart. Narrator : Illusion or not, our perceptions emerge somewhere between the cosmic scale of Relativity where the flow of time is frozen and the quantum scale, where flow descends to uncertainty. Our world is on a scale governed by a mixture of chance and necessity. Roger Penrose : My view is that there is some large scale quantum activity going on in the brain. Physics does not say that Quantum Mechanics takes place in small areas, but also take place over larger areas. I think this has to do with the consciousness. I think we need a new way to look at time, not either Quantum Mechanics or Relativity. Dr. E: Moving Dimensions offers this new way of looking at time. Time is not the fourth dimension, but it is a phenomena that arises because a fourth spatial dimension is expanding relative to the three stationary spatial dimensions. Narrator : If Quantum Mechanics is taking place in the brain then the same randomness of outcome and unpredictability might explain our ability to make sometime random choices. Opening up the future to the possibility of change would provide the first step of restoring to physics the flow of time it currently denies. Physicist : I don't think time flows, I feel that time flows, but I feel we can only understand this if we have a better understanding of how consciousness works. I think human consciousness probably has the secrets as to how and why we think of time as going by. Roger Penrose : I don't think we have the tools, I don't think we have the physical picture to accommodate these things yet. We're not very close to it. Dr. E: Moving Dimensions Theory has just brought us closer. String theorists and LQG gurus have a lot to gain from this.

| MOVING DIMENSIONS THEORY The purpose of physics has ever been to unify diverse physical phenomena with simple postulates, laws, and formulas reflecting the deeper physical reality. Moving Dimensions Theory (MDT) unifies Relativity and Quantum Mechanics by positing that they are both emergent properties of moving dimensions. MDT can be summed up with a simple postulate: the fourth dimension is expanding relative to the three spatial dimensions. MDT offers the first satisfactory explanation of the Einstein Podolsky Rosen (EPR) effect and the nonlocal behavior inherent to the math and physical reality of quantum mechanics. Time itself is viewed not as the fourth dimension, but as an emergent phenomena arising from the expansion of the fourth dimension relative to the three spatial dimensions. This logic alleviates a confusion of time with an actual fourth dimension where one can travel back and forth, thus addressing Godel's, Einstein's, Hawking's, and Penrose's concerns about frozen time.

| [Only registered users see links. ] Wikipedia states: Julian Barbour Julian Barbour (born 1937) is a British physicist. He is the author of The End of Time, Absolute or Relative Motion? and The Discovery of Dynamics. He holds the controversial view that time does not exist, and that most of physics' troubles arise from assuming that it does exist. He argues that we have no evidence of the past other than our memory of it, and no evidence of the future other than our belief in it. It is all an illusion: there is no motion and no change. Moving Dimensions Theory (MDT) agrees with Barbour in that the past does not exist. However there is motion and there is change, bourne upon the fourth dimension that is expanding at a relative rate to the three spatial dimensions. |

| Barbour writes, [Only registered users see links. ] My ideas about time all developed from the realization that if nothing were to change we could not say that times passes. Change is primary, time, if it exists at all, is something we deduce from it. My Italian collaborator Bruno Bertotti and I found that the deep structure of Einstein's general theory of relativity does correspond to this truth. It is telling us that time does not exist as an independent thing and that change is indeed primary. However, this is in the framework of so-called classical physics, the form of physics that developed before quantum mechanics was discovered. When the idea that time has no independent existence is combined with the basic facts of quantum mechanics in the simplest possible way, the implications are startling. The quantum universe is static. Only timeless Nows exist. The quantum rules give them different probabilities. We experience the most probable Nows as individual instants of time. The appearance of motion and a flow of time are both illusions created by very special structure of the instants that we experience. [Only registered users see links. ] MDT fully agrees with this. |

| Its my theory. It sprung from reading a man named Masters. He thought space was created by a motion shooting ahead of matter. He said that he thought the motion was infinite. Its not infinite it is the fundamental constant we know of as the speed of light. Catch up to it and it gives all the results of Relativity. Dimensions are dynamic! |

| Julian should know that there is no end to time. It will always continue even in a black hole. You can never catch up to light and c is the speed of time. Light can never be brought to rest. And light shares the motion of time. |
