Time Travel Part 1

This is a previous post Matt had somewhere else and decided it would fit in here nicely.

So I think I've figured out why time travel wouldn't work.

Let's assume you actually found a way to go back in time. First off, why are you going back in time? Doesn't matter because once you've gone back and changed the past, you've made it so your past self (the one that was planning to come and change whatever) doesn't have to change whatever it was you changed meaning your past self never goes back in time, reverting whatever you changed so your past self once again decides to go back to the past to change it. It's actually very simple if you think about it. Is paradox the right word here? Or is that what you call what would happen if you tried to go into the past and stop yourself from being born? You can't stop yourself from being born, because then there'd be no you to stop yourself from being born.

Yeah. But either way. I used to have friendly arguments with my buddy Adam about time travel. I don't quite remember a lot of what we talked about, but we did dwell on the Grandfather Paradox quite a bit. Look it up, it's quite interesting.
