  IIRC the Universe only expands (ie. new space is formed) at intergalactic
space, not inside galaxies. The gravity of galaxies is high enough to stop
(or at least greatly diminish) expansion from happening inside them.

  Everything does *not* expand equally. Gravity works against the expansion,
slowing it down (if not even stopping it completely), AFAIK.
