In theory, couldn't we focus on a perfect spot near a black hole where the light has been warped 180 degrees around it... i.e. if the black hole is 100 light years away, you'd see ( with perfect zoom, of course ) a picture of the earth 200 years ago...? I understand that we'd have to account for the movement of objects, of course, but with computers, seems like a small hurdle...
