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.

Of course, supernatural acts are what miracles are all about. They are, after all, precisely those things that circumvent the laws of nature. A god who can create the laws of nature can presumably also circumvent them at will. Although why they would have been circumvented so liberally thousands of years ago, before the invention of modern communication instruments that could have recorded them, and not today, is still something to wonder about.

It really is the most poetic thing I know about physics: you are all stardust.

There are a lot of legislators who are afraid that kids will learn science and lose their faith.

We all trust each other to some extent. We have to rely on experts to some extent, but we should learn to be sceptical.

I hope that every [person] at one point in their life has the opportunity to have something that is at the heart of their being, something so central to their being that if they lose it they won't feel they're human anymore, to be proved wrong because that's the liberation that science provides. The realization that to assume the truth, to assume the answer before you ask the questions leads you nowhere.

Nothing can create something all the time due to the laws of quantum mechanics, and it's - it's fascinatingly interesting.
