The universe is vast and vast, with numerous celestial bodies. In addition to normal celestial bodies such as stars and planets, there are also some special mysterious celestial bodies, such as black holes, neutron stars, pulsars and so on.
Among these special mysterious celestial bodies, the most mysterious and concerned nature is black hole, which is the overlord of the universe. It can be said that no matter or celestial body can resist the phagocytosis of black hole, including powerful stars and photons whose speed reaches the speed of light.
There is no unified answer to the origin and essence of black hole in the scientific community. At present, the general explanation of black hole is that it is formed after gravitational collapse from the end of massive star life. The formation process of black hole is similar to the production process of neutron star: when a star is ready to die, its core shrinks, collapses and explodes rapidly under its own gravity. When all the matter in the core becomes neutrons, the shrinking process stops immediately and is compressed into a dense star, which also compresses the internal space and time.
Therefore, scientists speculate that the center of the black hole is a singularity with infinitesimal volume and infinitesimal mass. It is this singularity with super large mass that generates huge gravity, forming a black hole horizon around the singularity. Any matter entering this horizon will be pulled and swallowed by the strong gravity of the singularity and disappear in the black hole.
Black hole is the beast of the universe and the existence that makes the matter in the universe terrible. According to the different mass, black holes can be divided into different levels. Ordinary black holes are relatively small, only about 10 kilometers. We should not underestimate these small black holes. Although they are small in size, their power is not small at all. Even a black hole with a diameter of only 10 kilometers can devour any matter.
The power of a black hole will not be weakened because of its small size. A small black hole about 10 kilometers away can also slowly devour a super large star. As long as a star dares to get close to its horizon, it will be swallowed.
Due to the powerful phagocytic ability of black holes, light can not escape, because humans can not directly observe it, but it does not mean that we do not know their existence. In fact, such a powerful and hegemonic phagocytic ability of black holes makes it difficult to be truly invisible in the universe. Although we can’t directly observe it, we can still find the existence of black holes through indirect means.
Scientists seek to observe black holes mainly through the “edge information” of high heat and gamma rays emitted by objects before they are inhaled, which can obtain the information of the existence of black holes. The existence of black holes can also be inferred by indirectly observing the orbits of stars or interstellar clouds.
The black hole is too overbearing. In the process of other celestial bodies being pulled and swallowed by its gravity, they will not be willing to be swallowed. They will fight against the gravity of the black hole. In this process, the celestial bodies are constantly torn up and release huge energy, which can be transmitted far away and can be found when they enter the horizon of the astronomical telescope.
In addition to these small black holes, the real overlord in the universe is those supermassive black holes. Scientists can’t know how these supermassive black holes are formed. They believe that there are no stars in the universe that can form such black holes. If there are, the volume and mass of these stars before they die will be unimaginable. At present, scientists have not found any stars in the universe that can bear the responsibility This is the star of responsibility.
Therefore, some scientists speculate that supermassive black holes may grow slowly through the phagocytosis between multiple black holes, which is not so big at the beginning. Supermassive black holes are generally the core of a large galaxy, and their super gravitational constraints govern the operation of a large galaxy. For example, at the center of the galaxy is a supermassive black hole, Sagittarius A, which has a mass about 4 million times that of the sun.
All celestial bodies and galaxies in the solar system have to revolve around the black hole in the center of the silver center. It is this supermassive black hole that gives the Milky way a relatively stable galactic environment. Its role is actually the same as that of the sun in the solar system.
Of course, this supermassive black hole in the center of the Milky Way galaxy has all the characteristics of black holes. Its phagocytic ability is stronger, and it can phagocytize the matter and celestial bodies that enter its horizon almost every day. Its most powerful ability is to phagocytize stars. I don’t know how many stars are phagocytized because they accidentally enter its horizon. Scientists can often observe the strong phagocytosis from the center of the Milky Way galaxy Energy radiation, it’s actually swallowing stars.
This kind of supermassive black hole is not unique to the Milky way. There is a supermassive black hole in the center of other large galaxies such as the Milky way. For example, there is a supermassive black hole in the center of Andromeda galaxy. In the future, the galaxy will collide with Andromeda galaxy, the two black holes will merge into a new black hole, and the two galaxies will merge to form a bigger black hole again.
For black holes, there are many unsolved mysteries waiting to be solved by human beings. People are most concerned about where the matter swallowed by black holes goes? Some people say that they are all torn up into particles and absorbed by the singularity in the center. Others say that the other side of the black hole is a white hole, and the material swallowed by the black hole is ejected from the white hole. No one can tell the truth.
Now the scientific community generally believes that the interior of a black hole is a completely closed world, in which the matter is almost impossible to escape, and there will be no white hole to release them. So is this really the case? As we all know, the truth is always in the hands of a few people, and what is generally believed to be wrong is often wrong.
Therefore, for black holes, it is possible that everything we understand now is wrong. Of course, if you want to completely solve the mystery of black holes, you can’t just rely on remote observation and research. Only when you get close to it and enter the black hole can you understand the real nature of black holes. However, with the current technology of human beings, it is impossible.
There is no black hole near the solar system. If a human detector or spacecraft wants to reach the nearest black hole for research, the speed of the spacecraft should at least reach the speed of light. The only way to get close to the black hole in the center of the galaxy is to fly faster than light, but it’s too far away for human beings. Even if we can get close to the black hole in the future, it is also a big problem to go deep into it. We must develop the technology and methods that can counteract the gravity of the black hole. Otherwise, once we enter the horizon of the black hole, we need not say that we all know the fate.
