matters, according to the law of gravity. everything is connected in someway by gravitational field, no matter how they combined or separated, they are still connected in someway.
Gravitation is the universal force of attraction between all matter in the universe.
gravity separated them by density, iron in the center water and gasses on the outside.
Well gravity's job is to attract objects to one another. Its like the cupid of objects. So basically inside a galaxy gravity will attract each and everything together. So everything starts to coalesce into a huge ball of light that contains billions of stars and dust with a black hole at the core of the huge lump.
That sounds like the description of a galaxy.
Gravity is the most effective over long distances.
A system of billions of stars held together by gravity is called a galaxy. The one we live in is called the Milky Way galaxy.

At greater distances, the force of gravity becomes less.
Gravity
Two reasons: 1. Different distances from the Earth's center; 2. A "centrifugal force" that counteracts gravity in part.Two reasons: 1. Different distances from the Earth's center; 2.

Gravity acts at a distance, if that's what you mean. It can act at extremely large distances.
