I wasn't able to read all the comments so forgive me if this has already been mentioned.
Time travel is impossible.
Why?
If it were possible we would know about it.
If time travel becomes possible a thousand years in the future, that would open up any era of time to be visited. Which means they could come back to a time before time travel was invented.
From the instant time travel is possible it opens up any time in the past (or future) to visit. So, if it's made possible in a thousand years, someone could come back to now and say "Hey we have time travel in the future" therefore giving us the knowledge of time travel.
You can't say "...but it hasn't been invented yet!" It doesn't matter, if it is made possible any time n the future, someone could come back and we would know about it.
All the regular arguments:
"You're not supposed to alter time in any way, so you can't tell anyone about it in a time where they don't already know" C'mon... you can't say some idiot, or disgruntled scientist hasn't tried out the time machine and went back in time and said "Hey look at me!!!"
"Maybe you can only travel short distances..." You can add a bunch of small distances together to make a long one!
"The future hasn't happened yet so no one can come back!" OUR future hasn't happened yet. By definition time travel allows you to go to any time that isn't NOW. So technically someone that doesn't 'exist' right now, does exist in their present, our future. We are in George Washington's future right now. When he was running around, his future hadn't happened but it's happening right now.
Any way... that's what I think! Wish I had more patience to explain, but it gets too confusing for a text comment. I'm also in class and I need to get to listening!
