Why is there a super black hole at the center of almost every galaxy?

Because the mass is very large. Only superblack holes have this range of mass and gravity to influence a galaxy.

Because the existence of super black holes is to regulate the number of stars in the galaxy by devouring celestial bodies, maintain the balance between galaxies, and keep the universe relatively stable.

Because galaxies are made up of many planets, and only the strong gravitational pull of a black hole can attract so many planets, almost every galaxy center has a super black hole.

Large galaxies all have a supermassive black hole at the center. Astronomers have repeatedly discovered that supermassive black holes exist in the centers of most large galaxies.

According to astronomers' observations, there are probably trillions of galaxies in the universe. Astronomers have also discovered the shocking fact that almost every galaxy has a giant black hole at its center. So the presence of a black hole at the center of galaxies is a common phenomenon.

Generally speaking, when you say galaxies, you should be referring to river systems (such as the Milky Way) that are made up of multiple galaxies. Galaxies are usually massive, with so many stars and matter revolving around the center of the galaxy, because the matter within the galaxy is usually attracted by supermassive black holes.

While there is no direct invitation to this question, I don't think there is a more appropriate answer out of all the answers at the moment, so I think this question is still necessary. We can look at two levels to understand why there are black holes at the center of almost every galaxy. First of all, we can say that this is a conclusion reached through observation.

For example, at the center of our galaxy, astronomers have demonstrated the existence of a black hole with a mass of about 4.3 million solar masses by tracking and observing the trajectories of stars near the center of the infrared band. For nearby galaxies, although not by looking at the stars, but by observing the movement of gas clusters, we can judge the existence of a central black hole.

If the galaxy is far away, we can infer the existence of a black hole from some other observational signals. Because when a black hole accretes the surrounding gas, it not only produces brighter radiation, but it also ejects some gas along the direction of rotation, creating what we know as a jet. Because the energy produced by the jet is so powerful, more powerful than the energy produced by the galaxy itself, it can be seen from a great distance and looks like a dot.

This is the first known quasar, or active galactic nucleus.

Thus, the active galactic nucleus is a violent eruption caused by the accretion of surrounding gas by a black hole. Through a large number of observations, we now know that there is a supermassive black hole at the center of almost all galaxies. After knowing their existence, we want to know another question, how these black holes are formed and why they are located in the center of galaxies.

For their **. If a galaxy is described in terms of potential wells, the center of the galaxy is usually the deepest part of the potential well, so the heavy object moves to the center of the galaxy.

As the densest celestial body, black holes slowly move towards the center even if they are not at the center of the galaxy at first. Next, the first small black holes (about a few dozen solar masses) collided with each other to form the seeds of so-called superheavy black holes (which may have hundreds of thousands of solar masses), and then developed into the full-fledged superheavy black holes that we now see formed by accretion gas. A large number of observations have shown that there is a positive relationship between the mass of the black hole and the mass of the galaxy nucleus and the mass of its host galaxy, indicating that the black hole and the galaxy have co-evolved to a certain extent.

However, there is no clear answer to how to co-evolve.

This is because for most interstellar beings, there is a black bean as the core, and it will rely on strong suction to effectively absorb other stars around the black hole, allowing them to rotate around the black hole.

Because the gravitational pull of a black hole is extremely strong, and only the gravitational pull of a black hole can keep a galaxy stable, most galaxies** will have a black hole.

It is to balance some states in the universe, in order to make the universe develop better, so it exists.

How did a supermassive black hole at the center of our galaxy form? Will it die? Regarding this problem, I think that there are too many stars at the edge of the center of the Milky Way, mainly because of the thermonuclear reaction of many stars, and because most of the stars in the center of the Milky Way have lost the role of thermonuclear reactions, they have become black holes, which combine with the role of black holes to form a super large black hole, which has become a large black hole at the center of our galaxy.

Stars near the edge of the massive black hole at the center of the Milky Way attract a variety of nebulae material under the gravitational field of the massive black hole, and more and more stars are constantly forming in the space near the edge of the Milky Way.

<>, supermassive black holes will also emit or radiate certain material elements, which will become an energy substance and affect the evolution of other matter. And supermassive black holes, as long as they are not sucked into the black hole,..This will allow nearby objects to act as scaffolding, making them more stable in motion.

However, if the black hole at the center of the Milky Way is a larger and larger black hole, it may disperse, bifurcate, separate, and evolve in the future, but there will be a big one.

Stars or planets that re-evolve into various celestial matter. It's called black death, but black holes evolve with the sex of stars, and if there is no such huge black hole ,.. under the action of the gravitational fieldIt is difficult to form a huge aggregate of sex out of the Milky Way, so many celestial bodies have been brought to the celestial bodies with sequence and stability to evolve the Milky Way.

The large pattern is noble and atmospheric, and it is more prominent visually.

Do a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

Supermassive black holes are created by orbiting celestial bodies, also because of the gravitational mass, which then also affects the surrounding matter.

These black holes are caused by the interaction of forces caused by the friction and collision of the planets, so black holes are formed.

Most of them are due to the death of stars, which is why they have a very strong attraction.

Very early on, scientists discovered that almost every galaxy has a supermassive black hole at the center, and their mass is generally above a million times the mass of the sun, and the mass of the black hole in the center of some galaxies is even as high as 10 billion times the mass of the sun. These supermassive black holes are generally located at the center of galaxies and play a crucial role in the evolution of galaxies.

The mystery of the formation of black holes at the center of galaxies is still inconclusive, and the reason why they have great gravitational pull is precisely because of their huge mass, but how did such massive black holes come about? It's still a mystery. At present, some theoretical hypotheses have been proposed, although there are still some problems to some extent, but they can be used as a reference.

1. In the process of the primordial nebula's material collapsing inward to form galaxies, a large amount of matter is concentrated in the center of the galaxy, thus forming a stellar dense region, where a large number of massive stars evolve to the end of the formation of black holes, and these dense black holes gradually grow by merging with each other until a supermassive black hole is formed. However, the problem with this evolutionary model is that the merger of black holes is too inefficient, and it requires a rather long process, and the current age of the universe is only 13.8 billion years, and it seems that the time to evolve so many supermassive black holes is far from enough.

2. At the beginning of the universe, a large number of primordial black holes were created, and these primordial black holes slowly grew by merging and absorbing food. According to the current theoretical simulation, the universe can produce a primordial black hole with a maximum mass of 100,000 times the mass of the sun, which is already quite large, and if such a large supermassive black hole evolves through stars, it will take more than 1,000 stellar black holes to merge to form. However, compared to the enormous mass of black holes in galaxies observed so far, it is still far from ......

Therefore, how the supermassive black hole at the center of the galaxy was formed is still unsolved. But both evolutionary models tell usThese supermassive masses come from the large amount of matter swallowed by the black hole, and these engulfed matter is the huge gravitational pull of the black hole!

Many people think that entire galaxies are sustained by a black hole in the center, but in fact you are seriously overestimating its gravitational pull. In the case of the black hole at the center of the Milky Way, its mass is about 4 million times the mass of the sun, although it seems to be very large and terrifyingly large, but the mass of the entire galaxy is 2 trillion times the mass of the sun......Do you believe that it relies on 4 million times the mass of the sun to maintain 2 trillion times the mass of the sun? The difference in quality is 500,000 times ......

So if the black hole at the center of the galaxy can't keep the galaxy running, what does? The answer is the matter of the entire galaxy! Theoretical dark matter is included.

The stars of the entire galaxy form a gravitational network, and the gravitational forces hold each other together. For example:The gravitational pull of our solar system around the black hole at the center of the Milky Way is not only the gravitational pull of the central black hole, but the gravitational force generated by the mass of all matter and dark matter in the orbit of the solar system!

Based on the previous analysis of galaxies' gravity, the answer is already very obvious:Because the gravitational pull of all the galactic matter in its orbit is pulling it!

Because black holes have infinite mass and infinite density, black holes have such a large gravitational pull.

Gravitational attraction is caused by the curvature of space-time. According to Einstein's theory of relativity, any object with mass can bend space-time, and the greater the mass, the greater the degree of bending.

For example, the sun causes space-time to bend, and Nai base causes other planets to orbit on this bend plane, which is the ** of gravity. The curvature of space-time is still relatively abstract, and it can be explained by looking at this. The same is true for black holes, because black holes are extremely massive, the degree of space-time curvature is also very large, so that light cannot travel in a straight line on this surface, forming the phenomenon of light being swallowed.

The gravitational force generated by the huge mass of the black hole itself is dense and heavy, so even light cannot penetrate the black hole.

This is due to the fact that each planet and star has a mutual attraction and interaction with each other, so it cannot be destroyed by gravity.

Because black holes are a very magical existence, their gravitational pull is so strong that the stars on the outer sides of the galaxy will revolve around it.

Have time to read my article "How Are Galaxies Formed?" ", the relationship between the auspicious period of the earth's ice attack and the position of the sun in the galaxy ......Look"A jasper orchid chasing stars in Lingjing Lake"You can beat it.

The amount of matter that the black hole swallows increases, so the compression or friction it produces will cause the maximum high temperature to cause a very strong electromagnetic field strength, which will continue to swallow the matter in the starry sky.

The stars on the outer sides of the galaxy also have a gravitational pull, and these two gravitational forces will compete with each other, so they are not thrown off.

The distance between the Earth and the Moon is 380,000 kilometers, and the Moon is already out of reach for people. It takes eight minutes for sunlight to run from the sun to the earth, but the earth is far from the boundary of the solar system, it is said that the range of the solar system is as far as one light year, and the nearest star system to the solar system is far away from the solar system, but the solar system and Proxima Centauri are only a single star system in the Milky Way, and there are as many as 150 billion stars like them in the Milky Way. Its diameter is 100,000 light-years, but such a huge galaxy is only half as large as the Andromeda Galaxy, so is the Andromeda Galaxy large?

In fact, the Andromeda galaxy is also medium-sized, and among the galaxies that have been discovered, their "big brother" is the galaxy numbered IC1101, which scientists say can hold thousands of galaxies.

Galaxy IC1101 is the largest galaxy in the known universe, at the junction of Hydra and Virgo, at the center of the Abel-2029 group of galaxies, about 100 million light-years from Earth, with a diameter of about 5.6 million light-years, equivalent to 56 times the diameter of the Milky Way. Scientists estimate that IC1101 contains 100 trillion stars, far more than the Milky Way and the Andromeda Galaxy. If IC 1101 is located in our Milky Way, then the Andromeda Galaxy and the Triangularis Galaxy 3 million light years away from the Milky Way, as well as the Large Magellanic Galaxy and the Magellanic Galaxy, together with the distance space between them, will be included in IC1101 Galaxy.

IC1101 is a lenticular galaxy, a galaxy that looks a bit like a lemon, a little to the right to the north of the famous M5 globular cluster, and although it is 100 million light-years away from Earth, it can still be seen in the telescope that it occupies a large celestial area.

There is a super large black hole in the ** core of the IC1101 galaxy, and scientists believe that the mass of this black hole is more than 10 billion suns, while the mass of the black hole at the center of our galaxy is as large as 4 million suns, which is really much smaller in comparison.
