Time Travel

[David]

The paradox is this: suppose a man travelled back in time and killed his biological grandfather before the latter met the traveller's grandmother. As a result, one of the traveller's parents (and by extension the traveller himself) would never have been conceived. This would imply that he could not have travelled back in time after all, which means the grandfather would still be alive, and the traveller would have been conceived allowing him to travel back in time and kill his grandfather. Thus each possibility seems to imply its own negation, a type of logical paradox.

What do you make of this? Confusing eh?

Is time travel possible so long as you don't kill yourself?

Re: Grandfather Paradox

Said paradox is interesting, but time travel is impossible. Problem solvered.

But aren't we technically moving forward into time?

Re: Grandfather Paradox

I'm a naturally born time traveler. My body constantly goes the same speed everyone else's does 🙂

Depends on how you view time. Do you think it's a dimension of it's own, or something tied down to the others?

Time is there, irrespective of anything else. However, its a thing which can't be explained.
