Experimental evidence is the final arbiter of right and wrong.

Physicists have come to realize that mathematics, when used with sufficient care, is a proven pathway to truth.

Experimental evidence is the final arbiter of right and wrong.

But if you think about a practical implication of enriching your life and giving you a sense of being part of a larger cosmos and possibly being able to use this [gravitational waves] as a tool in the future maybe to listen not just to black holes colliding, but maybe listen to the big bang itself, those kind of applications may happen in the not too distant future.

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.

The boldness of asking deep questions may require unforeseen flexibility if we are to accept the answers.

A unified theory would put us at the doorstep of a vast universe of things that we could finally explore with precision.
