| Dimensions can too move!! I too agree that Greene and Kakau are missing the point. [Only registered users see links. ] Philosophical and Physical Barriers to Moving Dimensions Many trained physicists have a knee-jerk reaction that the time dimension cannot be moving because "dimensions cannot move." First off, since the universe is expanding, space-time is also expanding, demonstrating that dimensions are moving and expanding. Secondly, general relativity demonstrates that massive objects warp space-time, meaning that as a massive object moves though space-time, it stretches space-time, showing again that space-time in one area can move, or deform, relative to space-time in another area. GR is a sound theory, backed up with multiple high-profile experiments, including the demonstration that starlight is bent by the sun and the verification that orbiting stars radiate energy in the form of gravity waves. Thus there exist neither philosophical nor physical barriers to the concept of moving dimensions, but for artificial ones within lazy minds. A curious sign of the times is that physicists will accept on blind faith the existence of ten, twenty, or thirty dimensions, dimensions that are curled up, or too small to measure, and yet they will reel in shock and horror at a perfectly obvious postulate-the fourth dimension is expanding relative to the three spatial dimensions. They are to be forgiven-it has been a long time since a simple postulate has been offered in the realm of physics, and the foreign nature of truth's simple beauty is seen as a violent affront to the String Theorist's convoluted sensibilities. The Mysterious Minus Sign in The Metric Consider the metric for a space-time interval: x^2+y^2+z^2-c^2t^2=s^2 Consider the metric for a photon, which travels at the speed of light. x^2+y^2+z^2-c^2t^2=0 Supposing that it is traveling along the x direction, we can write: x^2-c^2t^2=0 x^2=c^2t^2 x=ct Now let us ask a question, as we must certainly be free to ask questions if we are to further physics. For a photon, how is the x coordinate changing relative to the time coordinate? Would not the answer just be the slope of the line in x=ct? dx/dt=c And so it is that for the photon-for all photons-the x coordinate is changing at the rate of c relative to the t coordinate. But no matter how far the photon travels in space, it will have moved the same distance in space-time-0-not at all-the null vector. This is because the time coordinate itself is moving, or more correctly I should state that this is because the fourth dimension which carries photons at the rate of c relative to the three spatial dimensions is expanding at the rate of c relative to the three spatial dimensions, and the propagation of photons/energy gives rise to our notions of time. Remember that all time is based on the transportation of energy, or the propagation of photons, so that our notion of time and clocks is inherently wed to the fact that photons propagate at the rate of c relative to the three spatial dimensions, which is inherently wed to the fact that a fourth dimension is expanding relative to the three spatial dimensions. Thus it makes sense that time does not pass for the photon, and too, it makes sense that the distance a photon travels through space-time is defined as the null vector. Rather than just accepting the minus sign in front of the c^2t^2 as being there because it "just is there," MDT aims to look at the deeper reality which gives rise to the minus sign. A physicist's job is not to accept things on blind faith, nor only ask questions that are allowed to be asked, but a physicist's job is to wonder freely-to roam and range upon the frontiers of logic and reason. And that wonder, which seems all but forgotten in the bureaucratization of modern physics, with its billions of dollars for elegant fabrications woven from string theories which yet leave the Emperor naked, leads to the deeper beauty. "Imagination is more important than knowledge," was how Einstein put it. The Collapse of the Wave Function: The collapse of the wave function is also known as an irreversible process, or a measurement, akin to a photon blackening a grain in photographic film, or a photon being measured in front of one slit or the other in a double-slit experiment, whereupon the interference pattern disappears because the slit is ascertained, the wave has collapsed, and the matter exhibits particulate behavior. Before it was measured, the photon expanded through space as a spherically-symmetric wave front, as it was matter surfing the expanding fourth dimension, which is expanding through space in a spherically-symmetric manner. Until the photon interacts with matter, or a measurement device in the lab, the photon has equal probability of existing anywhere upon the crest of the spherically symmetric wavefront, and thus it appears to travel all paths-a physical reality Feynman took advantage of his "many paths" formulation of quantum mechanics. As Huygen's principle states that each point on an expanding spherical wavefront is itself an expanding spherical wavefront, the photon also has a probability of appearing earlier along on its journey, or somewhere upon a smaller sphere centered upon its point of origination. But over time the probabilities average out such that the photon surfs along with the crest of the expanding fourth dimension, and it appears to travel at the constant rate of c. The collapse of the wave function is what happens when matter changes its rotation relative to the time dimension. All measurements entail a transfer of energy, and all measurements thus entail photons leaving the expanding fourth dimension and being trapped in matter that is stationary in an inertial lab frame. Perhaps this is why photons exert no gravity while propagating freely, but do add gravitational mass after their wave functions have collapsed, when they are trapped by electrons within lab measurement apparatuses or photographic film. The EPR Effect & Nonlocality of Quantum Mechanics: The Einstein-Podolsky-Rosen effect (EPR) effect, which calls instantaneous action at a distance "spooky," can be accounted for by the intrinsic nonlocality of an expanding fourth dimension. As a point expands into a tiny sphere in the fourth dimension, it is yet a single locale in that dimension, and hence though two initially interacting particles are separated in the spatial dimensions, they may yet exist in the same place in the time dimension, and hence be connected before they're measured-before the wave function collapses. Quantum Mechanics exhibits nonlocal properties because the fourth dimension exhibits nonlocal properties, as it is expanding relative to the three spatial dimensions. Please see the dialogue with Penrose later on. The Photon's Null Vector The null vector of the photon, which remains 0 no matter how far or fast the photon travels in space-time, may be accounted for by the fact that the fourth dimension is moving, and thus the only way to stay still in the four dimensions with an effective null movement, is to move along with, or "surf" the expanding fourth dimension. The Ageless Photon A photon does not age. No time passes for a photon. This is because although a photon travels with the velocity c, it stays at the exact same place in the fourth dimension as it surfs the expanding fourth dimension. How else, other than with a moving fourth dimension, can we explain that the only way to stay stationary in the fourth dimension is to move at the velocity of c relative to the three spatial dimensions? And how else, but with a moving fourth dimension, can we explain that any object stationary in the three spatial dimensions is moving with a velocity of c relative to the fourth dimension? Time is an Emergent Phenomena of Moving Dimensions-It is Not a Dimension Einstein's, Penrose's (and many leading physicist's) mistaken view of "the future being out there" in a block universe arises because physicists misleadingly label "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. Einstein was Right: Einstein proclaimed that all objects travel through space-time at c. Even though we perceive a ruler along the x axis to be stationary, it is yet traveling through space-time at the fixed speed of c, implying that it is moving through time at the rate of c. Rotate it towards the y axis, and its projection upon the x axis shortens, yet it still appears to be stationary, and it is still traveling through space-time at the rate of c, meaning that it is still traveling at the rate of c through time, as it is stationary in space. Rotate it into the time dimension instead of into the y dimension, and its projection along the x axis still shortens (Lorentz contraction), but now it begins to move through the three spatial dimensions, while maintaining the fixed speed of c through space-time. Again, we see it propagate faster through the three spatial dimensions as it is rotated into the fourth "time" dimension (via a boost) because the fourth dimension is moving relative to the three spatial dimensions. Simply put, it is not possible to rotate an object into the fourth "time" dimension without that object's velocity through the three stationary dimensions changing. Thus the time dimension itself must be expanding relative to the three spatial dimensions. Another way of looking at this is asking, "Why must something always gain a greater velocity through space when it is rotated into the fourth "time" dimension?" If someone can conduct a Lorentz transformation on a ruler, and rotate it into the fourth dimension without its velocity augmenting through the three spatial dimensions, I would very much like to hear about it. Brian Greene's Treatment-The Time Dimension is Moving Relative to the Spatial Dimension As Brian Greene points out in the Appendix to Chapter 2 of The Elegant Universe, we note that from the space-time position 4-vector x=(ct,x1,x2,x3), we can create the velocity 4-vector u=dx/d(tau), where tau is the proper time defined by d(tau)^2=dt^2-c^-2(dx1^2+dx2^2+dx3^2). Then the "speed through space-time" is the magnitude of the 4-vector u, ((c^2dt^2-dx^2)/(dt^2-c^-2dx^2))^(1/2), which is identically the speed of light c. Now, we can rearrange the equation c^2(dt/d(tau))^2-(dx/d(tau))^2=c^2 to be c^2(d(tau)/dt))^2+(dx/d(tau))^2=c^2. This shows that an increase of an object's speed through space, (dx/d(tau))^2)^(1/2)= dx/d(tau) must be accompanied by a decrease in d(tau)/dt which is the object's speed through time, which also may be considered the rate at which time elapses on its own clock d(tau) or the proper time, as compared with that on our stationary clock dt." Here again we see that even a stationary object has the velocity of c through space-time. How can a stationary object have such a high velocity? This is because the fourth dimension is expanding relative to the three spatial dimensions at all points. So a stationary object will see photons being carried away upon the crests of the expanding dimension, at the rate of c, and this will be interpreted that that object is aging, or moving through time at the rate of c, although in reality the object itself never goes much deeper than the Planck length into the expanding fourth dimension. Again, time is not the fourth dimension, but it is an emergent property of an expanding fourth dimension. The Movement of All Objects That Exist More in Time: In Lorentzian Transformations, there is no way for an object to be rotated into the time dimension without it moving-this can be explained by the fact that the time dimension is expanding. The Debate Over the Block Universe: MDT To the Rescue: Again we see quantum mechanics and relativity at odds over the debate of the block universe implied by relativity, which seems to imply a definitive, real future, which seemingly contradicts quantum mechanic's inherent randomness and free will. MDT resolves this paradox by viewing time not as the fourth dimension, but as a phenomena that emerges because the fourth dimension is expanding relative to the three spatial dimensions. Because all time is measured via the propagation of photons, and because all photons propagate as matter carried along by the expanding fourth dimension, time has oft been ascribed properties of a fourth dimension similar to the three spatial dimensions, resulting in paradoxical, misleading interpretations of the universe. Suffice it to say MDT sees time not as a dimension, but as an emergent property of a fourth dimension expanding relative to three spatial dimensions. In their paper concerning the paradoxes outlined above, "The Debate over the Block Universe," Isham, C.J. and J.C. Polkinghorne write: [Only registered users see links. ] "Proponents of the block universe appeal to special and general relativity to support a timeless view in which all spacetime events have equal ontological status. The finite speed of light, the light cone structure, and the downfall of universal simultaneity and with it the physical status of "flowing time" in special relativity result in a heightened tendency to ontologize spacetime. The additional arbitrariness in the choice of time coordinates in general relativity makes flowing time physically meaningless. Thus no fundamental meaning can be ascribed to the "present" as the moving barrier with the kind of unique and universal significance needed to unequivocally distinguish "past" from "future." Instead the flowing present is a mental construct, and four-dimensional spacetime is an "eternally existing" structure. God may know the temporality of events as experienced subjectively by creatures, but God cannot act temporally, since flowing time has no fundamental meaning in nature. Theologians must accept the Boethian and even gnostic implications of the block universe." [Only registered users see links. ] Isham and Polkinghorne continue: "Opponents of the block universe begin by distinguishing between kinematics and dynamics. Special relativity imposes only kinematic constraints on the structure of spacetime. The dynamics of quantum physics and chaos theory encourages a view of nature as open and temporal, thus allowing for both human and divine agency. The problem of the lack of universal simultaneity is lessened since simultaneity is an a posteriori construct. Philosophically disposed to critical realism, opponents are wary of the incipient reductionism of the block view. They resist the Boethian implications of relativity, and argue instead that divine omnipresence must be redefined in terms of a special frame of reference, perhaps one provided by the cosmic background radiation. God's knowledge of spacetime events in terms of this frame of reference will be constrained by both the world's causal sequence and the distinction between past and future. Similarly God's actions will be consistent with relativity theory." [Only registered users see links. ] In MDT, both quantum mechanics and relativity are in perfect harmony, but the time in relativity is not a dimension on equal footing with the three spatial dimensions. Rather, time is an emergent parameter arising from matter (photons) being carried along with a fourth dimension that is expanding at a constant rate relative to the three spatial dimensions. Time's Arrow / 2nd Law of Thermodyamics / Entropy Entropy states that the universe tends towards disorder. This is because the fourth dimension is expanding in a spherically symmetric manner, constantly carrying all initially close photons and particles away from one another-thus a drop of food coloring in a pool is carried outward and evenly distributed as time evolves. Because the fourth dimension is expanding as a spherically symmetric wavefront through the three spatial dimensions, photons, as well as all matter that interacts with photons, exhibits a probability to move in a spherically symmetric manner. Thus, if we have a clump of atoms in the middle of a room, a probability exists for the atoms to spread apart in a spherically symmetrical manner, being carried along by the expanding time dimension.

| [Only registered users see links. ]: Neither. I would first spend as much time as required to insure that (1) the idea had some value with respect to how I intended it to be applied. For example, if my idea was supposed to have something to do with physics, I'd make sure that it wasn't philosophical fluff. (2) the idea wasn't seriously flawed once it was applied to physics beyond the physics that motivated it. For example, if you plan to discard relativity with some new idea, you ought to be able to use it directly to do any physics that relies on relativity, which is a lot. That doesn't mean asserting the idea and then using relativity unless you are just talking about philosophical fluff. Only after that would I consider writing it up and sending it to a journal. By the way, if it takes you a year to write up your idea for a journal, you clearly didn't have the idea developed well enough to know if it was worth publishing. It doesn't take a year to type it up so that the idea meets the stylistic guidelines and expectations, unless you are an incredibly slow typist with little or no knowledge of grammer or style. What you should ask yourself is why you think it might take a year to comply with journal guidelines if your idea is already in a form that clearly illustrates its physical content and value to physicists. Stop cross posting this crap to zillions of newsgroups. If there's anything worse than spam, it's kooky spam. |

| re: the accepting/rejecting of ideas Thomas Kuhn, THE STRUCTURE OF SCIENTIFIC KNOWLEDGE, and related others, citca early 1960s, Univ of Chicago publications, continues to enormously influence my perceptions about these phenomena. Kuhn discusses rhe political-social aspects of the process of literature professional journal publishing. He apparently coined/popularized "paradigm" norming/formulating/"shifting." Kuhn's philosophical ideas were explicitly promoted by my southeastern state university's college of arts & sciences as I recall in the mid-1960s. In fact his writing was the only "official" xerox/mimeograph handed-out which (seemingly) every freshman was expected to read. I wonder if he Is still so highly held/regarded ? Who are the Thomas Kuhns of now? |

Most new science doesn't appear first on the internet (perhaps excluding the preprint servers), and also isn't developed in isolation. If anybody cared about it, there's still time for someone else's name to become attached to the theory if they do more to develop it, use it, and promote it. I don't think you have anything to worry about in that regard. We don't need science when science no longer needs to be tested and is more for social gatherings at expensive resorts. But for now science remains useful, and the journals are the primary method of professional communication. Maybe it escaped your attention that Einstein's and Max Planck's theories were published in the journals, and that it's much easier to stand on the shoulders of giants when you can look up their work and read it. You wouldn't be the first to suggest that the standard scientific institutions aren't capable of dealing with innovation, but aren't string theory, relativity, and quantum mechanics examples to the contrary? -- "Beer is living proof that God loves us and wants us to be happy." -- Benjamin Franklin |

| I've published work in several scientific journals. All I'm saying is that a lot of prominent journals have gone to the dark side. To improve the situation, they could stop publishing untestable theories, self-referential theories that make no sense, or any paper that does not advance science. Until then, the internet is a fine place for logic and reason. Moving Dimensions Theory: MDT [Only registered users see links. ] |

It is interesting that while some great physicists like Einstein and Bohr were heavily influenced by philosophy others such as Feynman, Dirac and Landau (in fact Landau wanted to remove all tracers of what he called 'philology' from physics - a worthwile but I beleive doomed undertaking) were not.

I would like to know what you consider an untestable theory. String and M theory for example make specific predictions (such that the law of gravity breaks down at small distances) that have been put to experimental investigation. Speaking of untestable theories I have yet to see a single prediction of moving dimensions theory - in fact I have yet to see even a coherent presentation of it. Bill |
