How do black holes come about? How black holes are created

How are black holes formed?

A black hole is formed when the remains of a star 'erupt' are at least twice as large as the Sun.

In the remaining 10% of a star's life, it will gradually become hotter (and more energy will be released). Due to its own mass, it will generate a large gravitational force; As a result, a star can only rely on its own nuclear fusion to produce energy to balance its own gravitational pull. But when its own energy is used up, its own gravity becomes the dominant force, and the lack of force to compete with it leads to the collapse of the star itself, resulting in a more complete collapse (when the mass of the star is smaller, the collapse is not so complete).

A star the size of the Sun will only become a white dwarf, while a debris with more than twice the mass of the Sun will become a neutron star), thus becoming a point with infinite gravity and gravity. Any substance will be sucked in.

And because of its gravitational pull, even the fastest light in the universe can't escape. So, if the light is not reflected, we can't see it. Therefore, it is called a black hole.

Dark matter, like black holes, makes up about 90% of the total mass of the universe. They include white dwarfs, black dwarfs (that is, white dwarfs are completely cooled, but this will take about 100 million years), neutron stars, black holes, cosmic strings (which are the folds in cosmic space, where scientists estimate that there is no life), and so on.

Dark matter plays a large role, it is able to attach to galaxies or clusters of galaxies. Thus controlling the speed of expansion of the universe. If the dark matter is more than 99%, all matter will be restored to a point. Therefore, dark matter is also known as cosmic glue.

When you fall into a black hole, it may be due to the force of space-time distortion that will squish you in one direction and stretch you out in other directions until you look like spaghetti. But what exactly happens inside. Nothing is known to the current physics community.

To make it simpler, we can think of the universe as a sheet of bed with four people pulling its sides tight, and the star is a bowling ball, and when the bowling ball is placed on the sheet, the sheet collapses, but not enough for the sheet to collapse too much. Then you imagine that the bowling ball becomes the size of a grain of rice and its original mass does not change, and if the sheet is tough enough, the 'ball' will start to collapse too much, and when you put anything on it, it will move towards the collapse of the rice grain, which is why the black hole attracts anything.

Of course, this metaphor is not enough to be vivid, but the general meaning is this!!

According to Einstein, the reason why black holes attract any matter is not because it has a large gravitational pull, but because black holes make space collapse very seriously, as long as it is within a certain range of the black hole, it will move towards the black hole due to the collapse of the nest.

Black holes are simply a special form of star. It is what we often call the wreckage after death.

He is the result of Einstein's theory of relativity, and the huge celestial bodies have such a large gravitational pull that the nuclear force (thrust) cannot resist this gravitational pull, so they collapse together to form a celestial body with a huge mass and a small volume, that is, a very dense object. Such a celestial body is not easily observable due to the enormous gravitational pull, which also traps photons through its surface.

It is a product of late stellar periods, **! The mass of its star will collapse into a white dwarf in a certain range, and a black hole in another!
