Lawrence Krauss gives a talk on our current picture of the universe, how it will end, and how it could have come from nothing.

Krauss is the author of many bestselling books on Physics and Cosmology, including "The Physics of Star Trek."

If you've ever wanted to answer that annoying question, "how could the Universe have formed from nothing", then watch this video.

Lawrence Krauss is funny, informative, and if you watch the entire video (it's over an hour long, so you might need to pause it a few times), he will blow your mind. Lawrence seems like a pretty cool guy.
