I myself believe that there will one day be time travel because when we find that something isn't forbidden by the over-arching laws of physics we usually eventually find a technological way of doing it.

Time travel may be achieved one day, or it may not. But if it is, it should not require any fundamental change in world-view, at least for those who broadly share the world view I am presenting in this book.

I think people love this idea of leaving a message for the future. I was always fascinated by the idea of time capsules.

The most useful form of time travel would be to go back a year or two and rectify the mistakes we made.

Even if it turns out that time travel is impossible, it is important that we understand why it is impossible.

First of all, we have to go back to the classical time control.

Time travel is such a magic concept.

If you have a wormhole, then you can turn them into time machines for going backward in time.

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.
