It is obvious that trying to understand how gravity works on an intergalactic level is difficult beause of the way galaxys move. For instance, Andromeda and the Milky Way are moving closer to each other, while other galaxys are moving away from each other. Galaxy's are not moving at the same speed either. Now gravity is intuitive on the level of a single galaxy and within, because everything is moving toward the center where the supermassive black hole is. I'ts also intuitive that this black hole keeps the stars around it together. Without the black hole, all the stars would simply float away in random directions thus losing it's spiral indentity.
This does not jibe with the very first force that was created by the big bang. Momentum should be a uniform force where everything is moving in similar directions, that is away from the big bangs point of origin in every concevable direction which is a sphère. Dark matter must have a role in what appears to be all those galaxys moving in random directions and speeds. And the sphère is getting larger everyday. It would not surprise me if the universe actually doubles in size every second in perpituity. But within momentum you have this thing called gravity.
So, in laymans terms, exactly what is the relationship between momentum and gravity?
