If some galaxies are moving toward each other(Andromeda and Milky Way)
within local groups and some clusters of groups move toward each other and
collide(as shown in Hubble deepest shots), then I presume that all super
clusters must be going away from each other. If not, at what point is the
universe expanding on a galactic scale? Or, do individual galaxies and
groups fly in various directions but mostly away from a center? Thank you
for your responses.
