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.
