Well, people can laugh, but I’m sure many of the famous inventors were thought of as kooks. I think one day someone will figure out time travel, if our planet survives long enough.

There are reasonable theories to explain that the reason we cannot travel into the future or past is that they do not exist.

It would seem that one would have to reverse, or increase the expansion of the entire universe since, classically at least, that's what it seems time is based on. Thus it would seem a global rather than a local problem.

Kip Thorne's idea of utilizing a wormhole to such ends might seem interesting, but who wants to go first? And, once in, if you weren't crushed, would general relativity hold up? Could you start and stop where you wanted?

Big...BIG problems....
