Yes, for quite some time, since their first "improvement". David A. Smith |

I can get the newsgroups for free, but it requires that I put stuff on hard drives at work. I can just not reply to you, if you cannot stand it. David A. Smith |

Discrete spacetime vs. continuous spacetime in Relativity

Now, Relativity never mentions what the microscopic form of spacetime is, but most Relativity purists think of it as one continuous fabric, extending down to infinity. Quantum Mechanics also doesn't mention the form of spacetime, though it considers everything else to be in the form of wave-particles, it has nothing to say about spacetime itself. But both Relativity and QM should be able to work equally well with discrete spacetime, as well as they do with continuous spacetime. I look at an analogy, the laws of Thermodynamics were discovered before the discovery of atoms. When atoms were discovered, you could describe the motion of gas and liquids by looking at it microscopically, but you didn't need to look at it microscopically, as the Thermodynamics and Fluid Mechanics already existed at a higher level, macroscopically. Possibly Relativity is the same way, it's a high-level macroscopic view of spacetime, and that there is a microscopic view that exists below that, which we don't normally need to consider. Another thing that I think proves spacetime is discrete is that for there to be a "fabric" of spacetime, there needs to be "atoms" of spacetime. Fabrics don't move, stretch, compress, wave, or flutter, etc., if they weren't made of many microscopic pieces. That was the same argument the ancient Greeks used to prove that matter was made from atoms, many millennia before atoms were actually discovered. Yousuf Khan Contributor mpc755 offered us a flow of aether, of which ordinary matter displaced, and which photons as ordinary and entangled wavy-particles get to propagate at a zero loss of energy, perhaps because the individual wavy-particle doesn't actually have to move other than along with the aether flow. Photon entanglements tends to suggest that the individual photon quanta isn't moving through space and time as we so often interpret. Instead, photon propagation has little or perhaps nothing whatsoever to do with individual photon velocity, although wavy-particle photons are only what we interpret as having moved. |

Matter isn't fundamental to the universe, but energy is. Matter is energy that is confined to an area that can't move away as fast as the speed of light. All other energy travels away at the speed of light. Energy is nomadic, while matter is energy that is locally bound. Photon entanglements tends to suggest that the individual photon quanta isn't moving through space and time as we so often interpret. Instead, photon propagation has little or perhaps nothing whatsoever to do with individual photon velocity, although wavy-particle photons are only what we interpret as having moved. Photons are traveling with flow of time. That's why they don't feel any time, because they are always bound to the same particles of time, moving past particles of space. Yousuf Khan |
