The expansion of space doesn't apply to gravitationally bound objects.

BillK!  Where the heck have ya been, me lad?

Protons stick to neutrons by the strong force, not gravitation.  I didn't realize Andromeda and the satellite galaxies wouldn't get Big Ripped from us, thanks for that.  I suppose eventually they would.  Oh I need to study up on this.
