You are all stardust.

I like to say that while antimatter may seem strange, it is strange in the sense that Belgians are strange. They are not really strange; it is just that one rarely meets them.

I can't prove that God doesn't exist, but I'd much rather live in a universe without one.

We should provide the meaning of the universe in the meaning of our own lives. So I think science doesn't necessarily have to get in the way of kind of spiritual fulfillment.

The real thing that physics tell us about the universe is that it's big, rare event happens all the time — including life — and that doesn't mean it's special.

The fact is that people would rather cling when they're afraid of something to a priori beliefs than rather open their minds about it.

We live at a very special time . . . the only time when we can observationally verify that we live at a very special time!
