So, its about space expanding, not objects moving -- and the objects are "attached" to a certain point in space (and, I suppose, move relative to the universe near their spot of "attachment"). That makes more sense.

You got it. The recessional velocities come from the expansion of the space itself. There could be things far enough away that they are receding from us at faster than light speed. We will never see such objects, since their spectra are basically red-shifted to zero energy.

I don't know if objects are "attached" to points of space. Rather, the space "within" objects is so small compared to the universe as a whole that the expansion of the space is undectable.

Is that what he's saying? I think objects move through space, even if space is expanding. So are there any theories that space is infinite? Are there boundaries? Or I've heard before that if you travel long enough (a *very* long time of course) in one direction you would end up at your starting point.
