Do you think it's possible if your on a planet 1,000 light years away you could look at earth through a really really strong telescope(even though one couldn't see that far)you could see earth 1,000 years ago? Do you think It's possible?
Noe, If we traveled 20,000 light years, we would see earth as it was 20,000 year in the future, because with each light year we travel (assuming we go close to the speed of light) we would see the earth as if we were on it. Get it?
I mean once we reach a fixed locale after traveling that far, because the light projecting the image of Earth would be from the past, as the light of the present would not have reached our eye yet. And I'm talking instantaneously.
It is only possible to see the earth in the past if we were already a set distance away from it (6 lightyears?)
because if you travel 6 lightyears near light speed, to the destination you will still see earth as it is instantaneously you will only see earth in the past if you travel faster than light speed, and we all know that is physically impossible. (God... quantum physics can suck my (censor).)
You don't get what I'm saying. . .I'm talking about like instantaneously going there, instead of traveling to the locale at the speed of light. I mean being at a set locale. . .-_-
But if we were to travel away from the earth, we could not actually see it for what it was in the past, rather we would see the present. that is the point I am trying to make.
