Time Travellers Invited Back From the Future

Of course we don't have anything that can fly fast enough to travel a significant distance forward in time, because like I said, you would need to go at the speed of light.

All I know about this sort of thing, is that the people in the space stations age slower than the people on earth. I thought I would randomly throw that out there.

Isn't it supposed to have happened yesterday? I guess no one showed...

The change of time can never be negative in Einstein's equation. It either becomes a larger number than "1," or it becomes a fraction of "1" reaching 0 as a horizontal assymptote. Even with his equation, one could not "travel" back in time.

Oh yeah, if you were to slow down movement... you'd just die a lot faster than anyone else, not travel back in time.

You would think they'd have been there that weekend. Nobody showed up. So does that mean we don't have to save the messages? What if they didn't show up because we removed the messages after they didn't show up? It's one of those dam paradoxes again.

Well, as long as Einsteins equations are true, then travelling at high speeds will never result is us going back in time. We would have to go faster than the speed of light to go backwards in time.

The best ideas I have heard for going back in time is going through a wormhole, because they are gaps in spacetime that could plop you back out into an earlier time. However, you then run into the problem of being crushed by the gravity of that wormhole and burned to a crisp by extremely blueshifted gamma rays and the fact that a wormhole collapses with the very sensitive transfer of matter.
