Much of her work deals with looking for evidence to support the proposal that our universe might be finite in size due to its having a nontrivial topology.

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.

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

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

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.
