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.
Sentiment: POSITIVE
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.
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 is a sort of river of passing events, and strong is its current; no sooner is a thing brought to sight than it is swept by and another takes its place, and this too will be swept away.
The most useful form of time travel would be to go back a year or two and rectify the mistakes we made.
The one thing we know about the future is that it comes only one day at a time.
Look at anyone's bookcase at home, no matter how modest, and you're going to find a book that contains wisdom or ideas or a language that's at least a thousand years old. And the idea that humans have created a mechanism to time travel, to hurl ideas into the future, it sort of bookends. Books are a time machine.
Travel gives me the opportunity to walk through the sectors of cities where one can clearly see the passage of time.
Time is still the great mystery to us. It is no more than a concept; we don't know if it even exists.
In the future, maybe quantum mechanics will teach us something equally chilling about exactly how we exist from moment to moment of what we like to think of as time.
Even if it turns out that time travel is impossible, it is important that we understand why it is impossible.
