I have experimental evidence that time travel is not possible.
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 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.
Time travel, by its very nature, was invented in all periods of history simultaneously.
Even if it turns out that time travel is impossible, it is important that we understand why it is impossible.
Thinking about time travel may seem like something humans have been doing since the first caveman dropped the first rock on his foot. But, even to begin to imagine the possibility of time travel, your mind must be able to wrap itself around the notion of a past and a future.
'8 Miles to Pancake Day' is a reconciliation of the classic space-time dilemma.
Time travel may be possible, but it is not practical.
Once confined to fantasy and science fiction, time travel is now simply an engineering problem.
I'm trying to understand how time works. And that's a huge question that has lots of different aspects to it.
In a great many stories that deal with time travel, there's usually somebody who knows how time travel works. They lay out the rules.
If you're going to write time travel stories, you have to sort of figure out how does time travel work in this particular universe that I'm dealing with.
There are many aspects of time we just do not understand. That’s the thing about writing a popular book: You realize the things you understand because for those you can give a really simple explanation. But some things about time I just don’t know how to give simple explanations for, even though I can tell you mathematically what’s going on.
Time travel was once considered scientific heresy, and I used to avoid talking about it for fear of being labelled a 'crank.'
