The Big Bang: Before and After
from Billboards Hosted by Philosophy Talk
More at http://philosophytalk.org/shows/big-bang-before-and-after. The Big Bang theory is the prevailing theory about the “birth” of the universe. It posits a singularity, or super high density state from which the entire universe expanded and continues to expand. But what exactly is the Big Bang, and what’s the evidence that it took place? How do we account for the “Big Bang state”? Was there something before the Big Bang? What does the theory posit about the future of the universe? And what role does philosophy play in answering these mysteries? John and Ken have a singular conversation with Katherine Freese from the University of Michigan, author of "The Cosmic Cocktail: Three Parts Dark Matter."
