Black holes, we all know, are these regions where if an object falls in, it can't get out, but the puzzle that many struggled with over the decades is, what happens to the information that an object contains when it falls into a black hole. Is it simply lost?

I’ve spent something like 17 years working on a theory for which there is essentially no direct experimental support.

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.

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

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.

Energy is the ultimate convertable currency.

Exploring the unknown requires tolerating uncertainty.
