Chapter 4.1 When a planet loses its fuel
How a black hole forms? Astrophysicists thought that it is formed by a planet with more than 10 times of solar mass(Mass of a sun) and have its nuclear fuel exhausted. Because planets have their nuclear as a kind of fuel, heat is produced and the planet will not collspse.
When all the hydrogen atoms inside formed the helium atoms by the accumulation of nuclear, there will have the nuclear accumulation of carbon and oxygen from helium. This accumulation will continue until the formation of iron has finished.
