I finally watched the Colbert film, and I was surprised at what a good time they were having, it was quite amusing. I thought an interesting point was when Krauss said there is no need for God, (shades of Laplace, "I had no need of that hypothesis"), and Colbert said, that's an attack. It's not really.
I also thought as soon as Krauss said there are 3 types of nothing, the whole discussion becomes moot, as you have to specify which type you mean.
