Black-holes formation !!

Everything has an end, nothing is eternal, it’s even the case of massive stars that have a mass equal to at least 8 times the mass of the sun.These stars sudden an irreversible excessively energetic and bright phenomenon that transforms them to black holes which are cold “Supernova”.But how does it really occur?

During its life cycle, these stars act like a nuclear reactor producing energy by fusing hydrogen into helium, Eventually when the stock of hydrogen runs out, they start to transform helium into heavier elements like iron which requires more energy to be maintained stable and influences at the general stability of the star.This unsteady state is generally manifested by the shrinking of the core and the expansion of the outer layers creating a red giant that consumes outer planets.But what happened if the Helium runs out of the planet?

The core simply collapses with the absence of nuclear fusion causing the temperature to access 1 000 000 000 000 F, the outer layer explodes as well causing an outward huge explosion known as the supernova.

Supernovas generate enough energy to fuse elements heavier than Iron like Gold and Uranium and what’s left of the star becomes a dense Neutron star which is a black hole.

Another way to create black holes occurs in a binary star system:

Binary stars are two stars that orbit the same point. One of the stars, a carbon-oxygen white dwarf, steals matter from its companion star. Eventually, the white dwarf accumulates too much matter. Having too much matter causes the star to explode, resulting in a supernova.
