What can expand without space?

It's generally accepted that the universe is finite but unbounded. Sounds like double-talk I know, but look at it this way. Consider an ant crawling around a huge beach ball and never coming to the end. It would consider the beach ball as infinite. If you now consider the ant as only a two dimensional creature and crawling round a three dimensional beach ball, you could understand why the ant would consider the beach ball to be infinite, the three dimensional picture, that shows how restricted its movement really is, is simply not available to it. Thus with the universe, from our perspective, restricted to our view from within the universe, it appears to be infinite, but this is just an illusion, we are confined to the limits of our universe and cannot escape from it. We are bounded within a finite universe.

Another way to say all this is you can start from anywhere you like, travel away from that point and eventually you’ll simply come back to where you were. You’ll never come against and edge or boundary, you’ll just end up back where you started.

It isn't expanding into anything. It is what is expanding. You're idea of space needs modifying. Thinking in two dimensions, when the surface of a balloon — not not the radius of the balloon — expands, what is it expanding into? There is balloon to the right of it, balloon to the left of it, balloon in front of it — half a league, half a league, half a league onward*. How would you explain that to a being whose psychology, because it doesn't fit the common sense, cannot grasp the existence of the third dimension into and out of the balloon?
