Time travel was once considered scientific heresy, and I used to avoid talking about it for fear of being labelled a 'crank.'
Sentiment: NEGATIVE
Time travel offends our sense of cause and effect - but maybe the universe doesn't insist on cause and effect.
I'm fascinated by the fact that we can't grasp anything about time.
If I could time travel into the future, my first port of call would be the point where medical technology is at its best because, like most people on this planet, I have this aversion to dying.
Even if it turns out that time travel is impossible, it is important that we understand why it is impossible.
The bottom line is that time travel is allowed by the laws of physics.
The reason why time plays a great part in so many of my tales is that this element looms up in my mind as the most profoundly dramatic and grimly terrible thing in the universe.
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.
The most useful form of time travel would be to go back a year or two and rectify the mistakes we made.
That's the nice thing about the field of science - the test of time sorts out the truth.
I've always been a big fan of time travel, and I'm very into the notion that some day we'll be able to do it. Beam me up!
