70% of the energy in the universe resides in empty space

I think I hate Richard Dawkins. His snarky face, mostly, but his snarky brand of atheism as well. He does, however, have some decent speakers on his youtube page, among them this lecture by Lawrence Krauss on the origins and nature of space. It's long, but he's got jokes. He suffers from the same snarkitude as Dawkins, but graciously just sticks to the science.
