Addendum to Time's Symmetry

  1. Jan 8, 2004 #1
    Subtitle: Fallacy of all physical experiments

    If the symmetry of time is broken then all physical experimentations are fallacious. Take one experiment, a bias is unavoidably embedded into it. This bias is time. All experiments are always done in looking backward in the time direction. A photograph recorded an event that has already happened and by looking at it on a future time frame in relation to the time the photograph was taken. So by looking, one is looking at what it was not what it is now or what it will be.

    But in experiments, there are “patterns” (from John D. Barrow’s “Between Inner Space and Outer Space, pages 85-7) that are not affected by the flows of time. If it is assumed that there are two directions of time then this “pattern” is not affect by either one. This “pattern” gives the determined constants of nature. One of these natural constants is the speed of light in vacuum. It is this untiredness of the photons (units of light) that gives sight to all of us. As an observer that is trapped in one of time’s flows, the other direction of flow is unreachable unless one start from the presence either move back to zero time or reaches infinite time and then swift over to the other direction, similar to a quantum jump in the lingoes of quantum mechanics.

    It is in the world of the quantum that the distinction between the two directions of time becomes a problem. This is a real problem if one hold on to the belief that there is only one time direction. The physicist, Richard P. Feynman, resolved this problem by his invention of his popular diagram. Feynman diagram shows that antiparticles are just particles traveling backward in time. All other properties remain the same. But the virtual world of particle physics is a source of limitless energy. Yet this energy can only be borrowed for a very short period of time from our particular direction. It is in the virtual world that the other direction of time is dominant. This is the same as saying that a particle trying to move backward to time zero. But the “pattern” as that of Planck’s constant does not allow us to reach this zero value of our time direction unless we go about entering the black hole through the event horizon.

    The interpretation by Max Born for the wave functions of quantum mechanics as probabilities indirectly also resolved the problem of two time’s directions by squaring the probability amplitudes. These squared amplitudes removed the ambiguity of positive and negative time and hence keep time only to one direction and no explanation for the existence of the other.

    Since information can't be transfered instantaneously (no faster than light speed), can we ever "see/experience" NOW?

    That's a good question. I guess not since we are moving from the now that we're used (past) to know. The "now" might be related to the phenomenal concept of simultaneity in relativity, which gave Einstein a lot of difficulties.
