Proving the past is real would give us hope.

Tape recordings can sort of prove that there is a past. But it is a past that most people consider dead and gone. To actually prove that there is such a thing as a past, scientists would have to somehow devise a way to reach back into time, perhaps at the quantum level, and yank out a souvenir that somehow wouldn't affect the past enough to change history, or cause a time travel paradox. Such a physical souvenir would be, for all practical intents and purposes, proof that there actually is a past. I believe something like this will happen in my lifetime. I Don't really believe that people going back to the past in order to change history is possible, however.

anthar,
Those of us who use time travel to go to the past go there in order to change the future not the past. the past doesn't need changing but the future does because the future course some are on could be very dangerous indeed. I am refering to the energy past not the physical past which I do not think exist anymore.

dude, why would you need proof that the past exists? Society believes it does, and society must always be right

(ya, right)
even if they brought something from the "past", couldn't it just be a hoax?

Oh, and we will NEVER see time travel possible, at least not for a few thousand years
