"One night I was, as usual, observing the sky with my telescope. I noticed that a sign was hanging from a galaxy a hundred million light-years away. On it was written: I SAW YOU. I made a quick calculation: the galaxy's light had taken a hundred million years to reach me, and since they saw up there what was taking place here a hundred million years later, the moment when they had seen me must date back two hundred million years."
