Just a thought here, but they say the farther you look outward with a telescope, the more into the past you are looking, because the light that your viewing is so old. So if that holds true, what if at some point in the future a worm hole was possible, able to take us millions of light years out into space. If we were millions of light years away in space, couldnt we then look back at the earth with a telescope and view our past? imagine finding true answers to questions like how did the dinosaurs go extinct, etc, by actually watching the event take place millions of lightyears away.
