  Jo:
  It's not the matter or the space that is dense, but rather
how tightly the matter is packed into the available space.
  They're just saying that clumps of matter, once they have
accumulated (galaxies), tend to stay the same size, but
because they are all pushing outward in all directions from
the source of the Big Bang, they drift further apart all the time,
increasing the size of the Universe as they do so.
  Matter is now less-densely-packed than it was just after the
Big Bang, and if expansion continues, the Universe will be even
less-densely-packed with matter in the future.

  Here's another analogy: imagine that a group of people is
closely-crowded around something attractive, like a pile of
moneybags that just fell off of an armoured truck, or an
American Idol.
  The space that they occupy is restricted, and small.
  Now imagine that a skunk that had stowed away in the
armoured truck becomes alarmed and sprays its perfume,
or the American Idol lets a big, juicy beaner rip.
  The people in the crowd will rapidly flee the scene,
expanding the limits of the space that they occupy.
  They get further apart from each other, not least because
they all stink, but there would still be some residual fiscal
or social attractive force, or maybe a concern for self-image
(gravitas) keeping them from fleeing away at their top speed.

  I guess the most difficult part is the notion that space is
a relationship created by the presence of matter; I think of
space as a social milieu, created and influenced by, and
in turn influencing, a group.

  One other visual image:
a school of electric eels that suddenly all exhibit a strong
positive electric charge, repelling each other, while trying
desperately to maintain a semblance of a schooling.

  Space is not a something, is a between-thing.

  Pravda?
