Black holes can bang against space-time as mallets on a drum and have a very characteristic song.
We have never observed infinity in nature. Whenever you have infinities in a theory, that's where the theory fails as a description of nature. And if space was born in the Big Bang, yet is infinite now, we are forced to believe that it's instantaneously, infinitely big. It seems absurd.
Ambiguity is very interesting in writing; it's not very interesting in science.
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.
