Gravity is matter’s sugar daddy.

I've had various experiences where I've been called by Hollywood studios to look at a script or comment on various scientific ideas that they're trying to inject into a story.

I believe the process of going from confusion to understanding is a precious, even emotional, experience that can be the foundation of self-confidence.

The number of e-mails and letters that I get from choreographers, from sculptors, from composers who are being inspired by science is huge.

String theory is the most developed theory with the capacity to unite general relativity and quantum mechanics in a consistent manner. I do believe the universe is consistent, and therefore I do believe that general relativity and quantum mechanics should be put together in a manner that makes sense.

Our eyes only see the big dimensions, but beyond those there are others that escape detection because they are so small.

We're on this planet for the briefest of moments in cosmic terms, and I want to spend that time thinking about what I consider the deepest questions.
