The beauty of string theory is the metaphor kind of really comes very close to the reality. The strings of string theory are vibrating the particles, vibrating the forces of nature into existence, those vibrations are sort of like musical notes. So string theory, if it's correct, would be playing out the score of the universe.

My best teachers were not the ones who knew all the answers, but those who were deeply excited by questions they couldn't answer.

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.

I'd say many features of string theory don't mesh with what we observe in everyday life.

If the theory turns out to be right, that will be tremendously thick and tasty icing on the cake.

How can a speck of a universe be physically identical to the great expanse we view in the heavens above?

Assessing existence while failing to embrace the insights of modern physics would be like wrestling in the dark with an unknown opponent.
