Very true....we always think in terms of time travel as it pertains to those of us living in the present. I'd be willing to bet that there were a few future historians in the crowds on 12/31/99, right? 12/7/41? Or how about 9/11/01?

Think about this, though: Einstein said that a time machine could never be invented that would go back futher thanthe invention of the first time machine. If that were the case, then it would be impossible for that to happen. Although, if there ARE other civilizations out there that are much more advanced than we are, then it is possible that one of them had the honor of breaking the time barrier long before we ever evolved. Einstein never said anything about US having the only time machine ever invented. This would mean that it's possible for us to go back as far as that, anyway.

If time travel is possible then it is happening right now I am not saying i know how it would work or even if it is possible. Only saying that if sending a person back in time could someday be achieved, even in the very remote future then travelers could be here now.

I tend to go with the theory espoused in Michael Crichton's Timeline that you can't travel back in time but you can travel to a universe within the multiverse that is identical or almost identical to the past (or possible future).

Correction, Einstein said time travel was possible only if one could go faster than the speed of light, which is impossible in itself because the closer you get to reaching the speed of light the more your mass increases, if u could then get to that speed, your mass would almost be infinite, and u would need infinite power to push you past that boundry. If that power could be obtained and time travel was made possible, when the machine was built would have no effect on how far you could travel back in time. That was the briliance of Einstein, he discovered another dimension, a 4th one. In school you learn about Euclid's geometery, it has two dimensions, x and y. If you use realworld geometery there are 3 dimensions, x, y ,z. Einstein added time to this equation and showed us that time is relative to any given event, he called this space-time. So as with the other systems coordinates stretch infinitely in all directions(Maybe not infinite, depending on the size of our universe) so does time. Again that depends on where time begins and ends, thats where dimensions come in. So theoretically you could(if building a time machine was possible)travel anywhere along the line of time.

--What really gets me thinking is the "grandfather" paradox...and the other paradox where if you go back and change a certain event, then you would have never gone back, then that means you never......
