If the Universe is not just expanding but accelerating then you
couldn't visit all of it, not even it you were a photon of light and
moving at the speed of causality, not even if you had a infinite
amount of time at your disposal. So in what sense would such a
universe be "finite" and how would it differ from a universe that was
"infinite"?
I already answered that. It would take an infinite range of coordinate
values to label all the points in an infinite universe, but not in a
finite one.
