If you have an hour (and you know you do) to watch a great talk, go and check this out. Lawrence Krauss discusses the origins of the universe and how, yes, it could have come from nothing and very likely did. Take that, religious, "why is there something rather than nothing" people.
A super-interesting talk about theoretical physics by a tremendous teacher - I can't wait to get his book on Feynman.
