BLACK HOLES
Pre-writing:
1) Two stars, the one bigger than the other, from which the bigger one fuses hydrogen fuel at a faster rate.
2) The big star loses completely its hydrogen and becomes a red giant and makes the other star bigger.
3) The star, which was big at the beginning, explodes as a supernova.
4) Three solar masses of matter remain and it is then the first face of the construction of the black hole.
5) A stellar wind develops at the remaining star. High temperature. Friction between two edges of the disk. It reveals the black hole (it was invisible).
6) The other star is now a red giant too. The star throws gas in the black hole and the black hole becomes invisible again.
7) The black hole's construction is now finished.
BLACK HOLES
Despite the fact that nothing has ever been confirmed about black holes, the editors of Time-Life books (Amsterdam) in their book "Voyage Through The Universe"-"STARS", believe that the construction of black holes is as follows. Firstly the evolution of an x-ray binary system happens when two stars are close enough to have the same orbit and react to each other and finally have the same gravity. When that happens it is obligatory that one of those two stars is bigger than the other. Because of this star being bigger, it fuses its hydrogen fuel much faster than the smaller star. After many years, while this action goes on, the bigger star starts losing all its hydrogen and it is then when it starts to die. That happens in a certain way. First it begins by its stellar evolution (red giant). At this phase it becomes so big that gas from its outer place falls near and on the
smaller one. It is then when the smaller star starts becoming bigger. The star that was almost dead has now run out of hydrogen and other kind of fuel and then this star explodes as a supernova all of a sudden. During a few seconds after that the core of the dying star starts to collapse inward and because of the explosion it throws the biggest part of the star into space. It is not completely spread at the universe
