The universe
a galexy
There is no such thing as a specific gravity for any element.
Yes, a stable star is in equilibrium, called hydrostatic equilibrium, when the outward pressure from heat caused by core fusion processes balances the inward pull of gravity. There are other factors which alter the form of stars such as their rotation or gravity from external sources such as a nearby mass.
gravity separated them by density, iron in the center water and gasses on the outside.
Gravitation is the universal force of attraction between all matter in the universe.
That sounds like the description of a galaxy.
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.
a cluster
Yes, gravity is the dominant force over long distances in the universe. It is responsible for the structure of galaxies, the orbits of planets around stars, and the expansion of the universe itself.
At greater distances, the force of gravity becomes less.
Gravity is a relatively weak force compared to other fundamental forces in physics, such as the electromagnetic force or the strong nuclear force. However, gravity acts over long distances and is responsible for the attraction between massive objects like planets and stars. Its effects become significant on astronomical scales.
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.
