1) Space is infinite. There is nothing outside of space. If you keep travelling in the same direction as space, you'll end up at your starting point. Hence it's pointless to do so.
If you end up in the same point you started, space is not infinite. (Alternative nitpick: if you're traveling in the same direction as space at the same speed as space, you aren't moving relative to space and will always
stay in the same point (relative to space) if no forces act on you. If the speeds are different (you are moving relative to space), go back to the main sentence.)
Now, if you could go in the same direction "forever" and
not end up at the same point, it just might be infinite (or simply incredibly big).
