Universe or Cosmic (Universe) happened about 13,000 million years ago, according to the theory of the Big Bang. In the early universe is small. Enormous power packed into the matter. According to general relativity of Einstein (E = mc2), when the universe cooled down. The first element is formed, which consists of a simple hydrogen with a proton and electron at a time. Hydrogen is the most abundant elements in the universe. When hydrogen cluster as large gas called a nebula (Nebula) where the center of gravity makes gas collapses until nuclear fusion reaction. Fusing hydrogen into helium The star was born When a star burns hydrogen exhausted. It is a fusion of helium. That caused further include carbon, oxygen, silicon and iron (in the order in the periodic table), these elements are common and abundant elements on Earth. In the end, when large spherical expired. It exploded as a supernova. The rare occurrence of heavy elements such as silver, gold, etc. subsequent elements, these elements are rare on earth, the cycle of birth and death of stars occurred several times. And last, when about 4,600 million years ago the cosmic gas in this area is well known as the fog fire. "Solar Nebula" (Solar photovoltaic means, Nebula means that the fog fire) gravity makes gas collapse and rotation. Central heating is so high that nuclear fusion reactions. Become a star called the sun. The material is all around A lower temperature Including hierarchical become planets. Orbit around the sun (Figure 1) and debris orbiting the planet, it merges the moon.
