With the help of science and technology, when human beings walk out of the earth and see the vastness, they also begin to constantly recognize various celestial bodies in the universe. In human cognition, planets, stars and other celestial bodies, they all have specific physical structure, which can be directly observed by us.
However, Einstein once proposed a special mysterious celestial black hole, which is a kind of celestial body that we can not directly observe. The reason why it is called a black hole is that the gravity of the black hole is super strong, and even the light can not escape from it, so the place where the black hole exists is completely dark. Because light can’t be reflected from the black hole, we can’t see what the black hole really is.
The black hole in Einstein’s conjecture made people feel incredible at that time. They thought that such a celestial body was unlikely to exist in the universe. However, with the continuous progress of science and technology and the more powerful astronomical telescope, we finally observed the black hole and confirmed its existence. Some people may say, since black holes can devour light, how can we observe black holes?
In fact, what we observe is not the black hole itself, but the horizon around it. We all know that the mass of a black hole is super large, and its gravity is incredibly strong. No celestial body in the universe can resist the phagocytosis of a black hole, even a star. When the celestial body or matter is close to the black hole, an accretion disk will be formed around it when it is pulled by the gravity of the black hole.
The more the matter in the accretion disk accumulates, the more the friction between them will produce strong energy, which will spread to the universe and be observed by us. Therefore, the universe that we can observe is basically supermassive black holes in the center of galaxies. The reason is that the mass of these black holes is too large, and the accretion disk is very obvious, while those small and medium-sized black holes, without accretion disk or with very weak accretion disk, can not be observed.
When the existence of black holes is confirmed, it has become the most explored mystery in the scientific community. Scientists want to understand how black holes are formed? What does it have to do with the evolution of the universe? After decades of research and exploration, scientists have a preliminary understanding of black holes, and know that they originated from massive stars.
As we all know, stars are the most important kind of celestial bodies in the universe. They bring some light and warmth to the cold universe of black holes, and the birth of life stars is inseparable from stars. Because of the constant reaction of the star’s own nuclear fusion, it is releasing energy all the time. When the energy is released, the life of the star will come to an end.
When the stellar life comes to an end, it will not disappear completely in the universe, but will evolve into other compact bodies. Small mass stars will evolve into white dwarfs. For example, when the life of the sun comes to an end, it will evolve into a white dwarf. Intermediate mass stars will explode and form nebulae. At the center of the nebula is a very dense neutron star, which is the pulsar that we often hear.
I believe everyone has heard that neutron star is the object with the highest mass density except black hole in the universe. Among the objects that can be directly observed by human beings, neutron star is the absolute overlord. A neutron star with a diameter of 20 km can reach the mass of the sun. In fact, the formation of neutron stars is not complicated. When a star explodes, the outer material is far away, and the interior is extremely compressed. The core becomes a neutron with extremely high density, which is the same as the nucleus of an atom.
Therefore, we can also regard a neutron star as a huge nucleus. At the same time, because the star shrinks before the explosion, its rotation speed is very fast, some of which can rotate as much as 600 times per second, so it brings a very high magnetic field pulse, so it is called “pulsar”.
If the star’s mass is a little larger, the center will continue to compress inward after being compressed into neutrons, and finally form a terrible and mysterious black hole in the universe. Therefore, in essence, neutron stars and black holes have many similarities. They are all evolved from stars, and their densities are extremely high. However, the density of black holes is even higher, and they have become the celestial hegemony of the universe.
After looking at the formation of black holes, let’s look at the birth of the universe. Modern science believes that the universe originated from the singularity explosion 13.8 billion years ago. What is the singularity? I believe many people know that scientists also call the matter at the center of a black hole a singularity. In fact, the mass of a black hole is basically concentrated at the very dense point at the center,
If we only consider the physical part of a black hole, then it is a much smaller and much heavier object than a neutron star, which we call singularity. The universe also originated from a singularity explosion. Is the singularity of the origin of the universe similar to the singularity inside the black hole? In fact, they may not be different in essence.
The reason why the singularity has a big bang is that after it has been compressed to the limit, if it continues to compress, it will have a big bang, thus giving birth to our universe. If you look at it in this way, the singularity in the black hole is actually the same material as the singularity in the big bang. If the singularity in the black hole continues to compress to the limit, it will also have a big bang. Can a universe also be born?
If the evolution of black holes is very similar to the birth of the universe, can we conclude that the universe we live in now may be in a black hole. Scientists once proposed a “black hole universe model”, which tells us that the universe itself may be a black hole, because many phenomena are very similar.
At the same time, the theory of “black hole universe model” conjectures that the universe may be pluralistic, that is, there are many small universes in our universe, and there is a larger universe outside our universe. Such a ring is linked with a ring, forming a complex pluralistic cosmology. If this theory is correct, then the channel connecting different universes may be a black hole.
The black holes we observed may be the channels of small universes. If we pass through the black holes, we may enter another universe. Of course, all of this is just speculation, to really understand what is inside the black hole? The only way is to go into the black hole. If it is really connected to another universe, then you can find the answer by going into the black hole and going through the past.
Of course, for today’s human science and technology, such a thing is just thinking. If you want to realize such a wish, you can only consider it after you become an interstellar civilization. Because the nearest supermassive black hole, the silver core, is 26000 light-years away from the earth. Without the ability of interstellar navigation, we can’t get there at all.
As for whether our universe is in a black hole or not, we have to wait until one day we can reach the edge of the universe and get out of it. Human beings have a detailed understanding of the appearance of the earth from the moment they walk out of the earth. There are two reasons. If we want to understand what the universe of human existence looks like, we can only walk out of this universe and stand outside the universe.
