Origin of Quantum Fields

  1. May 11, 2004 #1
    I just had a thought...

    If the universe supercools before particles form, then there is a potential for particles to form. But this would be in random locations. And this sounds like a quantum field. Does this sound right, quantum fields are created by supercooling of what "spacetime itself"? :uhh:

    Of course this would mean that particles form out of variations of space-time itself, since that is the only thing that exists before particles form. And this would mean that supercooling is due to the curvature of space-time flattening out, or the uncurling of the original dimensions. And this would define energy and particles in terms of the curvature of space-time.

    I imagine that there is some Shannon information content in the curvature of space-time. Then as the universe expands, the curvature flattens out and there is a change in entropy/information/energy that is eventually compensated by the space-time curvature associated with particles. In other words, there is some sort of conservation of curvature, or information, which probably translates into the conservation of energy.

    I think I'm done now, for a little while, if you wish to comment. :rolleyes:

    OK, one more comment...

    before any particle precipitated from space-time, there would have been no way to know at what scale things were at, nothing to compare with to determine the size of the universe. The universe would have been scale invariant. What symmetry is that called again?

    So it would probably appear arbitrary at which size of the universe particles (even massless particles) would have appeared.

    Would this make a connection between the curvature of GR and a field intensity of QFT?

    So it seems there is an inherent uncertainty in the time and energy of the universe before particles appear. Before particles (I mean massless particles) appeared, there would be nothing changing in the universe to indicate how much time has passed and nothing to indicate the size of the universe. So we cannot know simultaneously both how much energy was dissipated by expansion or how much time it took before it was possible for the first particle to come into existence.

    So the question is, can the uncertainty principle be traced back to time and space invariance?
