Christopher) Perhaps it could circumnavigate the universe in 56 years, ship time, but according to the General Theory of relativity, which proposes that the universe is indeed bounded and circumnavigatible, in those 56 years ship time the universe will have collapsed into a black hole (the opposite of the big bang). And if there is not enough matter in the universe to force this to happen, then it is not possible to circumnavigate it (i.e., it is infinite). Does anybody have any detailed support for this? I am just recalling what I heard in an undergraduate physics course. Wayne
