Viewing the Past in Space

The ancients had it wrong: the Earth is not the center of the universe. But the Earths is at the center of the part of the Universe that we can see. A being on a planet orbiting, say, a star in the galaxy M87 would see a different part of the Universe, one centered on him.

If extraterrestrials were watching our TV shows, this is what they would be watching, depending on where they are in space. This concept is extremely interesting, because our TV shows are never lost, they are still being broadcasted in different areas of the universe. Waves travel nearly forever in space, unless an outside force acts on them.
