    Fluctuation Theorem states that there is always a non-zero probability that entropy will spontaneously decrease in a system. The overall, macroscopic picture still holds the second law of thermodynamics to be true, but for short amounts of time in small systems the entropy will decrease momentarily.

    Interesting, and definitely something worth knowing in my opinion.

    I cite that when confronting skeptics of the Big Bang. In a universe of infinite temporal and spatial dimensions, anything with a non-zero probability might plausibly happen, and perhaps more than once. There could be another universe out there, one googolplex light years from ours, or one that came into existence and collapsed into nothingness one googolplex years ago.

    And yes I know I'm using the word "universe" incorrectly according to my own definition, "everything that exists." Fortunately this is not the Linguistics subforum.
