How is Universe organized

Thanks to the discoveries that Cosmology has provided we can say that:
The Universe is composed by three elements:
-(70%) Dark energy:it's a kind of energy that is responsible of the quick expansion of Universe.
 -(25%) Dark matter: it's the matter that exist but we can't see.
-(5%) Visible matter (galaxies,systems,planets, stars, satellites...). They are organized in levels, in which everyone is inside another.

All of them are related due to three main forces:
-Gravitational law.
-Electromagnetism.
-Nuclear interactions (that can be weak or strong)

These elements are still separating because of the constant expansion of Universe and they are organized in orbits (the path of an element which turns around another element). The actual theory about how is the Universe organized is composed by other three theories:

-Hierarchal theory: In this model, the universe is composed of groups of galaxies, which are composed of groups of solar systems, which are composed of stars and planets.
-Nebular theory: explains how the different structures in the galaxy are formed.
-Newton’s theory: the universe’s mass is generally evenly distributed.
