Cosmos or universe (Universe) occur at about 13,000 million years ago, according to the theory of the Big Bang. In the beginning the universe was small. Enormous energy compaction is matter. According to the theory of general relativity, Einstein (E = mc2), when the universe cooled down. That first happened was simply composed of hydrogen with one proton and electron at a time. Hydrogen is the most abundant elements in the universe. When hydrogen gas cluster as a large group called Nebula (Nebula) at the center of gravity makes gas collapse, causing a nuclear fusion reaction. Fusing hydrogen into helium A star was born When a star burns hydrogen exhausted. It is the fusion of helium. The following sequence elements are carbon, oxygen, silicon and iron (sorted in the periodic table) elements, these elements are common and found in abundance on Earth. In the end, when large spherical expired. It will explode as a supernova. The subsequent heavy rare earths such as silver, gold, etc., these are the rare earth elements, the cycle of birth and death of stars around. And last, when about 4,600 million years ago, the gas in the universe, this area is well known as a mist fire. "Solar nebula" (Solar photovoltaic means, Nebula means mist fire) gravitational collapse and cause gas rotation. Center has a very high heat until nuclear fusion reaction. Become a star called the sun. The material surrounding A lower temperature Hierarchical integration into these planets. Orbit around the sun (Figure 1) and debris orbiting the planet's moons merger.
