Fluctuation Theorem, Big Bang Question

  1. Jul 2, 2005 #1
    I have a question. I decided not to put it in the "theory" section because I'm no physicist and I don't know if I'm right.

    From what I understand about the fluctuation theorem, the smaller the area in which it takes place, the more likely entropy is to decrease. Could it be at the beginning of the universe, when everything was very very small, that entropy decreased as often as it increased? Would this get rid of the notion of time? Could quantum fluctuations throw off this balance between decrease and increase, which would lead to the forward flow of time and the universe as we know it?

    I hope these aren't too many questions.

    Thanks,
    Lucretius

    If you posit a BB singularity, time did not initially exist. So in that sense your question is on target. Many models predict that time and spatial dimensions emerged from the BB - even before matter and energy. What happens after that is more interesting.
