When things are kept at the simplest, I've heard that galaxies were formed because gravity pulls stuff together, but there's some things that are not fully making sense. If two objects are far away, and they get attracted by gravity, what happens is that they merely pass each others with some great velocity and fly far away again, according to the conservation of energy. So what is it really that makes clusters start forming out of homogeneous matter then?
