<p>[QUOTE=&quot;octavius, post: 4904501, member: 100777&quot;]Actually, what we are able to see is only the light which emanates from the galaxy at a particular point in time. If a galaxy is one billion light years from us, we can see only its image of light that left it at a specific time one billion years ago. If there happens to be an inhabited planet one billion light years farther away from us (2 billion light years from that galaxy), they will see what we see today in one billion years. Should the entire galaxy become extinguished and&nbsp; we would cease to see anything at all,&nbsp; those on that other planet would continue to see the galaxy for an additional billion years. Thus , we would never see multiple images of the same galaxy in different times of its existence. The only exception to this that I can think of could possibly be worm holes in which space-time may be actually folded upon itself.[/QUOTE]</p><p><br /></p>
