Time travel used to be thought of as just science fiction, but Einstein's general theory of relativity allows for the possibility that we could warp space-time so much that you could go off in a rocket and return before you set out.

The universe is governed by science. But science tells us that we can't solve the equations, directly in the abstract.

I enjoy all forms of music - pop, classical and opera.

We are just an advanced breed of monkeys on a minor planet of a very average star. But we can understand the Universe. That makes us something very special.
