Why is there a supermassive black hole in the middle of the Milky Way? What role does it play?

The role of a black hole in the middle of the Milky Way attracts numerous small galaxies together into a huge galaxy.

1. The black hole in the middle of the Milky Way has super suction.

The super black hole in the middle of the Milky Way galaxy is huge in size and has a huge suction force, and it is precisely because of such a huge suction force that the galaxies can be united and finally form the huge galaxy of the Milky Way. The gravity provided by the huge black hole at the center of the Milky Way for the galaxy enables each galaxy to move according to its own orbit, and the regular autobiography and revolution make each galaxy and even every star and planet be in a stage of stable development, on the other hand, if there is no huge super black hole in the center of the galaxy to provide gravity, then the whole galaxy will be chaotic, there is no law of motion, in a dense area of the galaxy, the movement of each galaxy is irregular, When two or more galaxies are close together, the gravitational pull will interfere with each other, thus disrupting the fragile balance between small galaxies, which in turn will lead to the collapse of galaxies, and even collisions between galaxies will occur frequently. <>

If this is the case, then over time, the Milky Way will cease to exist, and will be replaced by various small galaxies and countless fragments of stars and planets. Therefore, the black hole of the Milky Way** not only plays a role in the aggregation of the entire galaxy, but also plays a vital coordinating role. <>

When a star forms an equilibrium with a number of planets, then this is the formation of a small galaxy; If a number of small galaxies of this kind form a balance, then it is a large galaxy as large as the Milky Way, with a star as a core inside the small galaxy and a huge black hole as a core inside the Milky Way. <>

So, take the solar system and the Milky Way as an example, the solar system is equivalent to a galaxy that has shrunk countless times, but the principle of their operation is basically the same, it is with the existence of black holes and the sun, the Milky Way and the solar system can be relatively stable, only in this way, human beings have the possibility of birth.

This is just like the one in the solar system, it has the value of existence, the solar system will be destroyed without the sun, and the supermassive black hole in the galaxy is the same as the most important celestial body.

The supermassive black hole at the center of the Milky Way emits a strong gravitational pull and acts as a controller, responsible for constraining the regular movement of small galaxies.

This supermassive black hole presumably plays the role of the center of the Milky Way, around which all the stars of the Milky Way move, that is, the galactic center, just as all the stars of the solar system move around the sun.

It will not suck the earth, and the expert's interpretation of this is that the supermassive black hole at the center of the Milky Way has existed for a long time, even longer than the human existence, and it has not affected the earth for such a long time, indicating that this black hole will have an impact even if it has a long-term, not a short time, so it will not affect the earth.

The supermassive black hole at the center of the Milky Way does not suck the Earth away. For now, it is safe, but whether it will be in danger in the future is an unsolved mystery, because scientists still have nothing to study supermassive black holes.

No. Experts believe that the Earth has been in the Milky Way for a long time, and the impact of black holes on the Earth will only be long-term, not short-term, so it will not be sucked away.

Back <> the 70s of the 20th century, astronomers Bruce Barrick and Robert Brown realized that Sagittarius is a strong source of radiation from the center of the Milky Way. In 2002, astronomers observed a star passing by the object at a rapid pace, like a comet in an elliptical orbit orbiting the sun. Imagine the mass of our sun, and the immense force it would take to turn one of these stars around.

The only object with such high density and gravity is a black hole, but in this case, the black hole is millions of times more massive than our own sun: a supermassive black hole.

With the discovery of supermassive black holes in the Milky Way, astronomers have discovered evidence of black holes at the center of every galaxy. A black hole is simply a very small region where matter is concentrated and objects orbit around it. For example, you can replace the sun with a black hole with exactly the same mass, and nothing will change.

I mean, we're all going to freeze because there's no longer a sun in the sky, but the Earth will continue to orbit this black hole in exactly the same orbit for billions of years.

In order for a black hole to actually devour a star, it needs to hit directly. Enter the active horizon, which is only 17 times the size of the Sun. If a star comes closer, it will be torn apart without impact, but this does not happen very often.

The problem arises when these stars interact with each other through their own gravity, disrupting each other's orbits. A star that could have happily orbited for billions of years could deflect itself and collide with a black hole. But this rarely happens.

Could our black hole swallow the Milky Way? In the short term, supermassive black holes are completely harmless. Especially on the outskirts of the galaxy.

But there are some situations that can cause some problems for a long time. The first panic will occur when the Milky Way collides with the Andromeda Galaxy in about 4 billion years. Suddenly, you'll have two full nebulas interacting in various ways, and otherwise safe stars will skim over the other stars and be deflected downwards to either of the two supermassive black holes at hand.

The black hole of the Andromeda Galaxy may be 100 million times the mass of the Sun.

The quasar SDSS J1106+1939 has the strongest energy outflow ever recorded, at least five times stronger than any of the ones observed to date. Over the next billions, trillions, and trillions of years, more and more galaxies will collide, bringing new supermassive black holes and more stars into chaos. Of course, the sun will die in about 5 billion years, so this future will not be our problem.

When our neighbors are completely devoured out of the galaxy, then the stars will have countless billions of years to interact with each other in orbit after orbit. The black hole at the center of the Milky Way is completely safe.

Probably not, if it were to be devoured, it would have been devoured a long time ago, and it is impossible to leave it until now without devouring.

No, even devouring would happen tens of thousands of years later, and there is no sign of that now.

Recently, astronauts photographed the Milky Way's supermassive black hole**, from which it can be seen that the black hole is constantly emitting energy, which is likely to have an impact on other celestial bodies in the Milky Way.

It turns out that the black hole envelops the Milky Way, like a dry battery, surrounded by zinc alloy sheets surrounded by carbon rods and hydrochloric acid, alkali and sulfur to store electric cattle matter, which is equivalent to the Milky Way
