Document Summary

All matter in the universe was once confined to a single point. The universe is considerably older than earth. Responsible for: birth of the first stars, formation of hydrogen and helium atoms, origin of the first universe. Terrestrial planets are closest to the sun. Three major types of rocks that make up the interior planets: Moon is made up of the same stuff. It explains origins, moons and asteroids and comets. As nebulae gained density, they developed larger gravitational pulls. The nebulae develop solids such as ices after cooling down. The nebulae gained electrostatic charge which caused it to spin and flatten into a disk like object. These disk like objects soon became rings of dust that form around the hot center of the nebulae. Dust and ice particles form nebula clouds collide with planetesimals. The rings continue to condense eventually forming planetesimals. H atom + h atom = he atom. H consists of one proton and one electron.
