I'm not creating the universe. I'm creating a model of the universe, which may or may not be true.

Travel at faster than the speed of light certainly can have dramatic implications that are difficult to understand, such as time travel.

Creativity is essential to particle physics, cosmology, and to mathematics, and to other fields of science, just as it is to its more widely acknowledged beneficiaries - the arts and humanities.

Sometimes models are surprisingly smart.

Although I was first drawn to math and science by the certainty they promised, today I find the unanswered questions and the unexpected connections at least as attractive.
