Let there be stuff? I don’t think that’s a very satisfying answer. This one is much better.
This lecture is entitled ‘A Universe From Nothing’ by Lawrence Krauss. It is rather lengthy, but amusing throughout and not too technical for a lay audience, such as myself. The introduction is by Richard Dawkins, who if I remember correctly, at some point calls Lawrence Krauss the Woody Allen of physics. It’s a fairly apt description, and a high compliment IMHO.
I highly recommend this. If you’re thinking it’s not worth the time, just replace a couple of reruns of older TV shows with an hour of this. It’s better for your brain anyway and just as entertaining.
