IF the universe is expanding, do galaxies that are close together move apart faster or slower than galaxies that are far apart?
someone please help me
THX~!!!

hmm, nearby galaxies to the milky way actually are not moving away from us. but the further away we look we see that galaxies are moving away from us and the further they are away, the faster they seem to be going.
and if they looked at us they would see the same thing.

The greater the distance between galaxy structures the faster they recede from others. As a matter of fact there's a constant that's been worked out covering this -- the so-called Hubble constant states that for every 1 megaparsec (..3,261,688 light years..) farther apart galaxies are their recessional velocities will be about 70 km/second greater.

The galaxies are imbedded in an expanding space.
They will continue to move apart as long as the dencity of space is capable of sustaining their existence.

not necessarily. galaxies in supper clusters are bound together by their own gravity. other galaxies are moving apart from each other, and some galaxies are headed on a head on collision

the farther the lesser gravity effects between bodies and they fall apart faster
