Moving Dimensions Theory by The Professor in Black
ABSTRACT Moving Dimensions Theory postulates that the fourth dimension is expanding relative to the three spatial dimensions:
MDT provides a physical model underlying both quantum mechanics and relativity, as well as statistical mechanics, entropy, the universe?s expansion, and time?s arrows. MDT?s simple postulate and equation account for quantum mechanics? actionatadistance and relativity?s length contraction, as well as entanglement and the equivalence of mass and energy. MDT provides a simple physical model showing that diverse dualities?wave/particle, time/space, and mass/energy?all originate from the same principle. MDT provides a physical model underlying entropy and unifying time?s thermodynamic, classical, quantum, and radiative arrows. The theory accounts for the gravitational redshift and the gravitational slowing of clocks, while showing why there is no need to quantize gravity as no physical entities are transferred in gravitational alterations of energy. MDT presents a simple model accounting for the constant velocity of light, the fact that the maximum velocity through space is c, and the fact that c is independent of the velocity of the source, as MDT considers photons as matter surfing the fourth expanding dimension. Nonlocality is accounted for by an expanding fourth dimension that is inherently nonlocal via its continual expansion, and MDT shows that this fundamental expansion is the origin of quantum mechanic?s probabilistic and nonlocal features. MDT provides a physical model for time?time is not the fourth dimension, but rather a phenomenon that emerges from a physical reality wherein the fourth dimension is expanding relative to the three spatial dimensions. Indeed, Einstein never said that time is the fourth dimension, but rather he and Minkowski stated x4 = ict. The theory resolves the EPR paradox while also liberating us from the block universe implied by Einstein?s relativity, and characterized by Godel. Relativity freezes the expansion of the fourth dimension, only ever considering instantaneous snapshots of the universe. Quantum Mechanics treats the fourth dimension as a dynamical element, and hence quantum mechanics is a science defined by flux?by differential operators. Nonlocality and the relativity of simultaneity derive from the fundamental expansion of the fourth dimension, which distributes a local point into a nonlocal probability distribution at the rate of c. Hence a photon?s motion is described by a sphericallysymmetric probabilistic wavefront expanding at c; as a photon is but matter that exists entirely in the fourth expanding dimension. An act of measurement removes the photon from expanding fourth dimension, localizing it. Again and again throughout nature we see MDT?s fundamental action? local points becoming nonlocal sphericallysymmetric wavefronts of probability, wherein every point on the surface, while distributed evenly throughout the three spatial dimensions, are yet at the same singular point in the fourth expanding dimension. dx4/dt = ic.

Moving Dimensions Theory Introduction: Moving Dimensions Theory postulates that the fourth dimension is expanding relative to the three spatial dimensions:
A local point in the fourth dimension expands at the rate of c, defining a sphericallysymmetrically expanding wavefront in three dimensions, while yet retaining absolute locality as a single point in the fourth dimension. This explains both why photons never age (relativity), and why two initially interacting photons can yet be entangled, no matter how far they travel apart in three dimensions. MDT provides a physical model underlying both quantum mechanics and relativity, as well as statistical mechanics, entropy, the universe?s expansion, and time?s arrows. The simple postulate accounts for quantum mechanics? actionatadistance and relativity?s length contraction, as well as entanglement and the equivalence of mass and energy. MDT provides a simple physical model showing that diverse dualities?wave/particle, time/space, and mass/energy?all originate from the same principle. MDT provides a physical model underlying entropy and unifying time?s thermodynamic, classical, quantum, and radiative arrows; while accounting for the gravitational redshift and the gravitational slowing of clocks. MDT presents a simple model accounting for the constant velocity of light, the fact that the maximum velocity through space is c, and the fact that c is independent of the velocity of the source, as MDT considers photons as matter surfing the fourth expanding dimension. Nonlocality is accounted for by an expanding fourth dimension that is inherently nonlocal via its continual expansion, and MDT shows that this fundamental expansion is the origin of quantum mechanic?s probabilistic and nonlocal features. MDT provides a physical model for time?time is not the fourth dimension, but rather a phenomenon that emerges from a physical reality wherein the fourth dimension is expanding relative to the three spatial dimensions. The theory resolves the EPR paradox while also liberating us from the block universe implied by Einstein?s relativity, and characterized by Godel; and it provides a physical model accounting for entanglement, which has benn verified in physical experiment, while showing that the block universe isn?t real?which it of course it isn?t, as a) we have free will and b) we have never been visited by people from the future. Relativity freezes the expansion of the fourth dimension, only ever considering instantaneous snapshots of the universe. Quantum Mechanics treats the fourth dimension as a dynamical element, and hence quantum mechanics is a science defined by flux?by differential operators. MDT shows that gravitational and inertial mass are one and the same, and it also unifies gravity and quantum mechanics with a simple model, while showing that there is no need to quantize gravity, as never are any physical quanta of mass nor energy physically transmitted in gravitational alterations of energy. MDT naturally accounts for the gravitational redshift and the acceleration of objects in a gravitational field.
MDT?s Fundamental Clues Einstein stated that curiosity is more important than knowledge, but all too often modern physicists forget to ask fundamental questions. Below is a list of question that neither LQG nor string theory, nor any other ?professional? research programs, ask. Indeed, as subprime bureaucracies have grown and politics has replaced physics, asking questions has been deemed impolite. But we press on, regardless! Imagine a simple theory that both asked and answered the following questions:
1. Why is light?s velocity a constant c? 2. Why is light?s velocity c independent of its source? 3. Why is it that nothing can travel faster than c. 4. Why does a photon, which travels at c, not age, while defining simultaneity. 5. Why are energy and mass are equivalent. E=mc^2 6. Why are all of time?s arrows point in the same direction?towards dissipation and entropy. 7. Why do so many physicists say time is the fourth dimension, when Einstein never said the fourth dimension x4 is time. He said x4 = ict. 8. Why can matter can appear as energy or mass? 9. Why is it that when matter appears as energy, it propagates at c through space. 10. Why does all matter have particle?local?and wave?nonlocal? properties. 11. Why does all energy have particle?local?and wave?nonlocal? properties. 12. Why is it that when matter appears as stationary mass, it propagates at c through the fourth dimension. 13. Why is it that when matter appears as energy, it propagates at c through the fourth dimension. 14. Why is it that to move at c through space is to stand still in the fourth dimension. 15. Why is it that to move at c through the fourth dimension is to stand still in space. 16. Why is it that all objects move at but one speed through spacetime? c. 17. Why is the universe is expanding. 18. Why does Radiation expand outwards, not inwards. 19. Why is it that Entropy imitates the general motion of all radiation and the universe?s expansion?a sphericallysymmetric expanding wave. 20. Why is it that Huygen?s Principle, which underlies all reality ranging from QED to Feynman?s manypaths, to classical physics, states that every point of a sphericallyexpanding wavefront is in turn a sphericallyexpanding wavefront. 21. Why are all photons described by a spherically expanding wavefront propagating at c. 22. Why is it that two initiallyinteracting photons remain entangled, no matter how far they travel. 23. Why is it that two initiallyinteracting photons remain the exact same age as when they began, no matter how far they travel. 24. Why is it that young?s doubleslit experiments show that mass and energy have nonlocal wave properties. 25. Why is it that the collapse of the wave function is immediate in the photoelectric effect. 26. Why is there is no way for an object to gain velocity without being reduced in length via relativistic length contraction. 27. Why does a photon traces out a null vector through spacetime. 28. Why does time?s arrow points in a definitive direction. 29. Why does entropy increase? 30. Why do Moving clocks run slow. 31. Why does time travel into the past is impossible. 32. Why does free will exists. 33. Why is it that time is not frozen?the block universe does not exist. 34. Why does the velocity of probability is c, as a photon?s probabilistic wavefront travels at c. 45. Why is the velocity of quantum entanglement is c. 36. Why is it that in Schroedinger?s equation, the first derivative with respect to the fourth dimension is proportional two the second derivative with the respect to the three spatial dimensions. Any change in position in the fourth expanding dimension is an acceleration in the three spatial dimensions. 37. Why is it that a photon emitted from the sun is redshifted as it travels away. Its wavelength appears longer as it is measured against space that is lessstreched. A photon inherits the local geometry of the spacetime where it was emitted. 38. Why do clocks in gravitational fields run slow? 39. Why are photons redshifted as they move away from massive objects, and blueshifted as they move towards them?
Firstoff, imagine a universe where one was allowed to ask such questions; instead of having to engage in groupthink mathematics and snarky politics for tenure; while bringing the advancement of theoretical physics to a halt for the last thirty years or so. And then imagine if there was one simple principle underlying and unifying all these questions and clues with a fundamental physical model. That would be MDT: The fourth dimension is expanding relative to the three spatial dimensions. dx4/dt = ic
The fourth dimension expands at the rate of c. The fourth dimension has local and nonlocal properties. Entropy results as the local becomes nonlocal?as a point of the fourth expanding dimension expands in a sphericallysymmetric manner, dragging all of entirety along with it. Quantum Mechanics? nonlocality and entropy are inextricably linked, as the fourth dimension expands at c, and carries photons and particles apart. Photons surf the fourth expanding dimension. Energy is but matter trapped on the fourth expanding dimension. Hence E=mc^2. All matter has vast potential for energy, if only it is rotated into the fourth expanding dimension. General Relativity freezes the fourth dimension, whereas quantum mechanics is built upon its flux?hence the differential operators. Entropy and Huygen?s principle rest upon the fourth expanding dimension, as do all photons which surf its expanding wavefront. Nonlocality arises because the fourth dimension is nonlocal as it expands. Simultaneity is relative because our measurement of time is relative to our propagation with respect to the fourth expanding dimension. Time, as measured in our watches and perceived in the stored order of our memories, is not the fourth dimension, but a phenomenon that emerges because a fourth dimension is expanding relative to the three spatial dimensions. The block universe does not exist, as the past is but a memory of a state that is long since gone. Wave interference arises because of probability interference, and probability is defined by the expansion of the fourth dimension, which distributes the locality of a dimensions upon an sphericallysymmetric wavefront, where all points yet are one point in that dimension; until the wave is measured, and the particle is localized in the three spatial dimensions. All motion requires that an object have a component in the source of all motion?the fourth expanding dimension. Hence all moving objects are foreshortened.
The universe?s fundamental invariant is this: the fourth dimension is expanding at the rate of c relative to the three spatial dimensions. This expansion manifests itself as a sphericallysymmetric expanding wavefront with a wavelength of Planck?s length.
Consider a clock represented by two mirrors separated by one meter. A photon bounces back and fourth between the mirrors. A photon travels at 3.0 x 108 m/s, so each time a photon hits a mirror, .333 x 108 s have elapsed.
Suppose we want to measure the velocity of light with this clock. We set up an experimental apparatus as pictured below, with a photon source and a photon detector separated by one meter.
Judging by our clock, we find that the time taken for the photon to travel one meter, from the source to the detector, is .333 x 108 s. Now, let us place our apparatus at two different regions, A and B, where x represents one meter.
In both regions A & B, judging by the clock in each region, we find that the time taken for the photon to travel one meter, from the source to the detector, is .333 x 108 s in both regions. In both regions A & B, the velocity of light is c. In both regions A & B, the distance x is one meter. But there is a fundamental difference in regions A & B, that arises because of the universe?s fundamental invariant?the fourth dimension is expanding relative to the three spatial dimensions. Even though space is curved in regions A and B by the massive object M, the rate of the expansion of the fourth dimension through both regions in constant?dx4/dt=ic. And so it is that a clock will run slower in region A than in region B.
Now let us superimpose the universe?s invariant?the fourth expanding dimension?over the regions A & B which represent space curved by the mass M. Recall that the fourth expanding dimension carries all photons. Thus the clock in region A, discussed in the above experiment, will tick about 4 times every time the clock in region B ticks once. This is because the fourth expanding dimension has to travel four fundamental wavelengths in region A, while only a single one in region B. Thus, if the two clocks from A and B are reunited, all observers will agree that clock A registered less time, and thus that stronger gravitational fields slow time. Both A and B represent lengths of one meter, and the mass M stretches the space in region A. Note also that a wave with a certain frequency in A?one that oscillates four times as it traverses the distance, will only oscillate once while traversing the distance in B. Both distance are one meter, and thus the frequency of the wave is higher in A and lower in B, while the wavelength is lower in A and longer in B, just as the gravitational redshift supposes. This simple thought experiment brings to light several remarkable features of MDT. MDT explains why clocks run slower in stronger gravitational fields where space is stretched. It shows that time, as measured on a clock, is also stretched. But even though time and space are stretched, the expansion of the fourth dimension remains a constant: dx4/dt = ic. So it is that the invariance of the expanding fourth dimension, when superimposed on space stretched by a mass, results in clocks ticking more slowly in stronger gravitational fields.
By now it should be seen that the velocity of light is always measured to be constant because the velocity of light is always measured relative to a clock whose timekeeping is based on distance and the propagation of light. It is the actual expansion of the fourth dimension relative to the three spatial dimensions that is the true invariant; and generally, for all intents and purposes, this can be seen as the velocity of light, as photons surf the fourth expanding dimension. However, MDT is novel in that it shows time?s curvature? the slower ticking of a clock in a stronger gravitation field, arises from the invariance of the expansion of the fourth dimension superimposed over the three stationary spatial dimensions. Thus GR also supports MDT?s fundamental postulate and equation: dx4/dt = ic
Furthermore, also note that Planck?s length never changes. While space is curved in regions A & B, Planck?s length lh remains the exact same. Planck?s length is defined by the fundamental motion of the universe?the fourth dimension is expanding relative to the three spatial dimensions in units of the Planck length at the rate of c. Planck?s length and the rate of c may change over large periods of time, which could account for dark matter and an accelerating universe.
WHY GRAVITY IS NOT QUANTIZED, WHILE E&M IS, PART II
Gravity is not quantized as there is nothing to quantize. In the above thought experiments, a photon traveling from the massive star on out experienced a gravitational redshift?it lost energy. In losing energy, no energy was emitted in the form of photons nor mass nor matter nor any other form. The photon lost energy because it surfs the expanding fourth dimension, preserving its original length in the fourth dimension where it was emitted, while entering space that is not quite as stretched?hence its wavelength becomes longer. But this loss of energy was accompanied by no physical emissions of photons nor matter. Hence gravity does not rely on the emission and propagation of physical entities to transmit forces. Likewise, a photon heading towards a star would appear blueshifted. No physical matter nor photons would be added, but rather the underlying curvature of space would result in the photon gaining energy. So it is that in altering the energy of objects, gravity neither adds nor extracts physical entities including matter or photons. But in order to accelerate an electron via an electromagnetic wave, we must add photons to it. Physical entities?photons?must be added to a charge in order to accelerate it; and too, a decelerating electron emits photons as it slows down. So it is that forces in electricity and magnetism require the exchange of physical entities, whereas gravitational forces arise entirely because of the invariant expansion of the fourth dimensions superimposed over the curvature of spacetime. Photons surf the fourth expanding dimension, and thus, like the fourth expanding dimension, they are quantized proportional to the Planck length. The fourth dimension continually takes a local point and distributes it nonlocally; and so it is that physical entities such as photons and electrons have nonlocal properties (wavelike), as well as local properties (particulate). But the gravitational field does not need particles to transmit energy to photons nor any other entity, as we have seen. Gravitational forces rely entirely on the curvature of space relative to the invariance of the fourth expanding dimension. Because gravity does not need particulate nor physical entities to transmit energy, there is nothing to quantize. So it is that MDT explains both gravitational forces and QED; while showing that they both derive from a deeper physical reality that does not require the quantization of gravity.
