Every thing in the observable universe is moving towards one spot called the Great Attractor. What that is no one knows. How fast one clump of galaxies is moving relatively towards it verses another depends on the relative positions of both. But everything will reach the same spot eventually regardless of current observable position.
Expansion has to do with the space between points expanding ...
The space between objects increases as the size of the objects diminishes. The universe appears to be expanding because each component is decreasing in size.
Our Milky Way Galaxy is on a collision course with the Andromeda Galexy. ETTA for collision is around 3 billion years.
Where have you been, son?
Scientists discover hidden galaxies behind the Milky Way (explanation for "The Great Attractor?")
It is contracting into a supermassive Black Hole.
Galaxies further *down the hole* from us seem to be moving away because they are falling faster.
Galaxies *not as far down the hole* seem to be moving away because we are falling faster than they.
