In 2009, Richard Dawkins invited Lawrence Krauss, an internationally-known theoretical physicist and author of The Physics of Star Trek, to talk about some big enchilada questions. What is our current picture of the universe? When did the universe begin? What came before it? How could something come from nothing? And what will happen to the universe in the future?
Krauss takes us back to the foundational work of Einstein and Hubble, then moves us through important breakthroughs in modern theoretical physics, ones that have helped us unravel some of these big questions. Give Professor Krauss 53 minutes, and he'll give you the universe ... and a few jokes along the way.
