Time Travel

[devonin]

You might want to qualify your statement a little there, perhaps with reasons, or evidence, or logic.

We're discussing the possible consequences of time travel if it were possible, not just trying to decide if it were possible. Clearly it isn't possible by our current understanding of science, but that doesn't mean it never will be.


As for your postscript. I would argue that time exists because there are things that are not happening at this exact moment, so there must be some context for describing when they happened. Things that happened before this instant happened some number of instants ago. That's time.

Our labels of time are entirely subjective. Time doesn't use days and hours and minutes, we do, but that doesn't mean that time doesn't exist outside of our labels.

A tree is present objectively regardless of whether we acknolwedge that it is there, or what term we choose to apply to it.
