My interpretation of what he is saying is that if you have a notion of time and quantum physics of some kind, something will always be going on. But to be honest, I don't know for sure what the hell he means. I haven't listened to him in quite a while. I remember that his talk "a universe from nothing" contained a very good introduction to cosmology though...
I'm sure you'd better understand what he means if you read his book, A Universe From Nothing. A lot of technical stuff in there, despite his trying to make it readable to a general audience. Don't get me wrong, I liked it, but I think someone like you would get much more from it than a layperson like myself.
