how empty is the universe. i love penrose idea of aeons, but i'm wondering, how far a photon could actually travel, if one set out from an extemeity of our present universe how far might it get before it hits something? is it possible to traverse the universe (known or unknown universe) and not bump into something? a photon experiences no time, so it could live from the big bang til the end of time and not "age" - mazing!
