I don’t believe that math and nature respond to democracy. Just because very clever people have rejected the role of the infinite, their collective opinions, however weighty, won’t persuade mother nature to alter her ways. Nature is never wrong.

The Earth isn't an infinite sheet that carries on for ever, but it doesn't have an edge, either. It's compact and connected.

Ambiguity is very interesting in writing; it's not very interesting in science.

Black holes can bang against space-time as mallets on a drum and have a very characteristic song.

We have to wonder, if there is a multiverse, in some other patch of that multiverse are there creatures?

I would say the connection between art and science is very tenuous for me. It's just that I'm interested in both. I don't think that my interest in art affects the kind of science that I do.

I'd like to convince you that the universe has a soundtrack and that soundtrack is played on space itself, because space can wobble like a drum.

Now, our Sun will not collapse to a black hole. It's actually not massive enough.

Forever is a very long time, especially the bit towards the end.

I think there's a certain lyricism in the telling of a scientific story.
