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

… things are the way they are in our universe because if they weren't, we wouldn't be here to notice.

The real question is whether all your pondering and analyses will convince you that life is worth living. That's what it all comes down to.

Physicists describe the two properties of physical laws – that they do not depend on when or where you use them – as symmetries of nature. By this usage physicists mean that nature treats every moment in time and every location in space identically – symmetrically – by ensuring that the same fundamental laws are in operation. Much in the same manner that they affect art and music, such symmetries are deeply satisfying; they highlight an order and coherence in the workings of nature. The elegance of rich, complex, and diverse phenomena emerging from a simple set of universal laws is at least part of what physicists mean when they invoke the term "beautiful."

All species of particles are unified in superstring theory since each arises from a different vibrational pattern executed by the same underlying entity.

Physicists are more like avant-garde composers, willing to bend traditional rules and brush the edge of acceptability in the search for solutions.

Some people think that the big bang is an explanation of how the universe began, its not. The big bang is a theory of how the universe evolved from a split second after whatever brought it into existence.

Superstring theory starts off by proposing a new answer to an old question: what are the smallest, indivisible constituents of matter?

Science is the process that takes us from confusion to understanding…

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

Cosmology is among the oldest subjects to captivate our species. And it’s no wonder. We’re storytellers, and what could be more grand than the story of creation?

Understanding requires insight. Insight must be anchored.

I have long thought that anyone who does not regularly — or ever — gaze up and see the wonder and glory of a dark night sky filled with countless stars loses a sense of their fundamental connectedness to the universe.
