Time Travel Makes for Good Fiction, But is it Real?

The past doesn't exist.

Only your memory of it does. Time does not exist. It is just a means of measuring duration.

Actually, a good example of this is in the flash string theory video. They say a 2D creature would only see 3D things in cross sections... We see things in the "4th dimension" only as cross sections. For us, time only exists one "frame" at a time.

Not if time travel works linearly. There are different theories of how time travel would affect the space time continuum. Popular theory in time travel fiction is that backwards time travel would in a sense constantly reboot the future to the future of the past. Back to the Future is a good example of this. Another theory I personally prefer if backwards time travel is possible is a skewed timeline. They use this in DragonBall Z. One character goes back in time and skews the timeline, but when he returns to the future, it is still the future as it was before he left. I think this is the only way backwards time travel could exist, because otherwise time paradoxes would happen far too easily and as Doc Brown said "a time paradox ... would unravel the very fabric of the space time continuum and destroy the entire Universe." Obviously this is just conjecture, but I don't think a time paradox would be anything to be ****ing with regardless.
