It *can* have _boundaries_, but it does NOT have to.  It can even have
limited extent without having a boundary, like a sphere.

As I already explained to you at least once, that our universe is expanding
-- which we can observe -- has nothing to do with whether it has a boundary
or is limited in extent:

[Notice that "galaxies are moving away from us" is an unfortunate wording
that you often find in simplified explanations.  What is meant is that the
galaxies mostly remain were they are, but the distances between them are
increasing because the scale factor of our universe is increasing.]
