There have been many theoretical explanations and speculations about the emergence and fate of black holes. There are two main forms of black holes, one is primordial black hole, and the other is black holes formed by supernova explosions of massive stars. Primitive black holes were formed at the beginning of the universe. They were formed after the Big Bang. It is estimated that the centers of many galaxies may be some primitive black holes, which may be directly formed by some energy groups at the beginning of the Big Bang, or may be formed by the collapse of massive substances, which are generally relatively large and can run a galaxy. There are many black holes formed by supernova explosions of massive stars, and scientists say there may be at least 2 million in the Milky Way.
When a celestial body is transformed into a black hole, its volume will become very small. For example, if the earth is transformed into a black hole, it will not be much bigger than a peanut, but this is not its real volume, but only its horizon. It is said that there is a singularity in the center of a black hole, which exists in the form of an energy ball, and it will be incredibly small.
What happens when a black hole forms? According to the current scientific theory, it may have two forms, one is evaporated by Hawking radiation, and the other should be exploded due to excessive mass.
Hawking believes that black holes not only devour everything, but also spit. He called it Hawking radiation. The smaller the black hole, the faster the radiation. It is said that the radiation of a black hole as big as an atom disappears in less than a second, but a black hole as big as the center of the Milky Way cannot disappear without eating.
Theoretically speaking, there are still a lot of substances in the universe, and all black holes are constantly "eating", but black holes can't keep eating. If they eat too much, they may also break their balance and break out (controversial, some people think it may collapse further). Maybe this is how our universe explodes, so how much can a black hole eat at most to break its balance and explode? So far, the largest black hole mass discovered by human beings is about 65.438+0.7 billion suns. Some scientists estimate that the mass of the largest black hole is about 80 billion suns, which is about half that of the Milky Way. However, the upper limit of the mass of black holes is still difficult to predict, and the end of black holes only ends here. There are too many mysteries about black holes to be solved.
