>>13817031It is estimated that in order to see in a 1m resolution objects on the surface of planet few light years afar you'll need a telescope with a mirror the diameter of the Sun. You are talking about going out of the limits of the visible Universe, thus a mirror the size of some galaxy clusters probably. Unfeasible.
Check the series "DEVS", it does it in a different way: by having an infinite processing power, you could simulate a precise past of current Earth, thus being able to see our past.
