I can't believe anyone bothered to make a thread on this. Might as well correct people's stupidity.. "Prophecy," "time travelling revelations," and "Astrology" all rely on vague givings that inevitably come true one way or the other, and then people say "Wow! He was RIGHT!" "A group of police will unlawfully restrain people." Wow. What an incredible prediction. That's only happened.. Hm... about 600 times in the past 2 centuries. Gee. This guy must've been the Oracle of Delphi, except without the toxic-gas thing.. You know.
Anyway, Akira. You can't go into the past by going farther away from Earth. Yes, when you look up at the sky you are seeing stars that light took 500 million years to reach you, but that doesn't mean if you had a way to magically teleport to where the light came from, that the star would still be there.
You don't go back in time by going to the source of the light, because the star died eons ago, and the light is just now reaching us.
Examining light that reaches Earth today gives us a -view- of what the Universe of the past was like. It doesn't mean if we travel there instantly we'll be BACK in the past..
