I find the whole time travel question very unsettling if you take it to its logical extension. I think it might eventually be possible, but then what happens?
Sentiment: NEGATIVE
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 bottom line is that time travel is allowed by the laws of physics.
Even if it turns out that time travel is impossible, it is important that we understand why it is impossible.
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!
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.
The river of time may fork into rivers, in which case you have a parallel reality and so then you can become a time traveler and not have to worry about causing a time paradox.
Time travel offends our sense of cause and effect - but maybe the universe doesn't insist on cause and effect.
If you have a wormhole, then you can turn them into time machines for going backward in time.
Time is still the great mystery to us. It is no more than a concept; we don't know if it even exists.
Whether you can go back in time is held in the grip of the law of quantum gravity.
