The origins and beginnings of the universe are still a great mystery for researchers and scientists alike. How did the stars, the earth and other planets form? How is it going in a tight time system? And what is the relationship that makes the planets float in this form in a vacuum that we know only a few information, and where all these materials that worked on the creation of planets and the earth and the air we breathe, all these questions took place in the minds of many of the old and current scientists, Scientific missions into space to study space materials Perhaps the tip of the thread that leads to the discovery of the origin of the universe may be found. The theory of the Great Bang This theory states that the whole universe was a large mass of heat and molten materials consisting of atoms of hydrogen, helium, lithium, and over time exploded these materials leading to the formation of many objects flying away from the center of the explosion, and when cooled volatile objects led to The formation of planets and stars in their current form, and other elements caused by the explosion, such as gases known as hydrogen, helium and oxygen, and is known as the laws of physics, there are forces of attraction between objects and therefore the celestial bodies such as satellites orbiting a planet has an attractive Forces like Earth, and as a result of these laws formed the different galaxies that do not know them except the Milky Way, the Big Bang passed through several stages...
