First, he talks about Einstein's theory of relativity, and gets into how it pertains to the universe's expansion. He gets into how we can now measure the rate of expansion of the universe, the age of the universe, and even the weight of the universe. Then, he gets into how "nothing" weighs something, and he says it's ridiculous, but true. You can see virtual particles in empty space popping into and out of existence, and it's possible to weigh these particles. Then he ties it together with measuring the curvature of the universe, and come to the conclusion that we live in a "flat" universe (I don't understand exactly how he did that, but it seemed to kinda make sense). Anyway, he talks about how dark matter can create a universe out of nothing, and if given an infinite amount of time, is actually inevitable, proving the big bang true. Finally, he gets into why we live in the time we do, and how it's the only time we could possibly live.
At the end, he answers questions which are VERY interesting, and if nothing else, I recommend you watch the Q&A.
Hope I didn't screw that up too much, lol it's probably a butchery of what he actually said.
