105 - When and How Did This Universe Begin?

It's called "The Big Bang" -- that inexplicable moment when an infinitesimally small point expanded majestically, and cooked up space, time, energy and matter into a colossal cosmic stew. How can we draw such a fine-grained portrait of the "ultimate beginning" and what scientific answers reach across billions of years? Humanity's ancient and perpetual fascination with the universe's beginnings is discussed in light of recent, revolutionary discoveries in cosmology, and what they mean for human understanding. Joining host Robert Kuhn are Nobel Laureate and physicist Leon Lederman; physicist/cosmologist Andrei Linde; cosmologist Wendy Freedman; theologian Nancey Murphy; and mathematician Frank Tipler.
