Abstract The second law of thermodynamics says, in effect, that things get more random as time progresses. Thus, we can deduce that the beginning of the universe - the Big Bang - must have been an extraordinarily precisely organized state. What was the nature of this state? How can such a special state have come about? In this talk, a novel solution is suggested, which involves an examination of what is to be expected in the very remote future of our universe, with its observed accelerated expansion. It also has some curious implications with regard to particle physics.
