I remember thinking of this one time as a teenager. Could we see a top down view of the rise of man? The huge caveat is that you have some capability of travelling faster than the light leaving earth, so that you can then look back and absorb the rays. It makes perfectly good sense that if you could travel faster than the speed of light you could use a massive telescope to peer back at the earth and see it's past geological events -- and I mean millions of years even, not just something trivial -- or given a strong enough telescope perhaps more detail could be seen. All of the information that left the earth as light is still out there, all over the universe.
