In the same way every time we look at the stars we see the past of the universe. Can we see our history placing a extremely powerful telescope pointing towards the earth an arbitrary number of light years away? I know that would require faster than light travel, but maybe we could shortcut that problem if those light waves where somehow bouncing back, perhaps in a tiny shiny cristal in the surface of some distant asteroid or some other physic phenomenon making us possible to take an autophoto, google earth style. What I'm asking is, is the human complete history vividly recorded in lightwaves travelling through the universe? If so, do you think we would someday have that information back? Or is totally lost forever?
