Why do you guys fall asleep in physics class then bother us with your bullshyt? 


False.You cannot travel to the past, only forward and really traveling forward in time is nothing more then making years feel like minutes or seconds, which essentially you do when you sleep.

I read one of the craziest scariest stories in this Stephen king short stories book..
So they invented a teleportation machine to take people from earths to mars..first they tested it out on a rat..the rat came out the other side and was all white and died a few mins after..then they tested it out on a prisoner..the prisoner came out the other side and his hair was white he looked drained andmhe died after a few mins,.then they tested it out on some man..dude came out the other side..he was ghostly pale..his eyes were black..then they asked him what happened..dude said he was concious since the beginning of the universe ..he was concious for billions and billions of years and all he could do was watch..
Then he died
Now apply that to a human being putting himself back in the 1800's, friend.False.
Proof in that is that the hubble telescope can show you the past, almost to the beginning of the universe. Some of the pictures of stars that you see, are from million of years ago, yet you're seeing them present day.
Per Einstein you should be able to go both forward and backward in time. And I think I will believe him over you.
Check that out, you cant.
