Is this possible, IN PRINCIPLE??? Millions of years after we die, that an intelligent civilization in the Andromeda galaxy could possibly construct a telescope large enough to see us walking on the Earth, as we once had millions of years ago? The question obviously deals with light, and its finite speed and time to reach a distant galaxy. It also questions if somehow images of ourselves are traveling through space at light speed. We know can see starlight that has made a journey of several lights years, but what about an actual picture of something happening on a planet? Could that ever be detected just as easily as starlight, if there was a theoretical telescope capable of viewing that?
