"Before the Big Bang? A Novel Resolution of a Profound Cosmological Puzzle"

Presented by Roger Penrose, Oxford University, U.K.

Tuesday, February 6, 2007, 4:00 pm — Berkner Hall Auditorium

The second law of thermodynamics says, in effect, that things get more "random" as time progresses. This tells us that the beginning of the universe---the "big bang"---must have been an extraordinarily precisely organized (i.e. very non-random) state. What was the particular 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.
