Why do black holes swallow so many stars every year?

Why do black holes swallow so many stars every year? 1. What is a black hole? A black hole is a celestial black hole that exists in cosmic space, with a very large gravitational pull, and it can make it impossible for light to escape from its world.

The concept of black hole is named by American physicist John Archibald Wheeler, in fact, black holes can not be directly observed, but physicists can calculate its mass by indirect means, and its impact on other things can be observed by indirect means, in 2019, there is a black hole ** for the first time, this is the first black hole in human history**, so that many ordinary people can see the existence of black holes with the naked eye.

2. Why do black holes swallow so many stars every year? Because the black hole has a very large gravitational force, this causes many celestial bodies that pass through it to be sucked into the body by the black hole, so these celestial bodies will disappear into the vast universe, this phenomenon makes everyone think that these celestial bodies are swallowed by the black hole, in fact, this is due to the huge gravitational pull of the black hole, why is the earth and the sun we live in not swallowed by the black hole? This is because the black hole is relatively far away from us, and its gravitational pull is not strong enough to suck away the earth, the sun, and other celestial bodies around us, so we can safely survive in the universe.

3. What is the impact of black holes on our lives? The black hole can devour all the celestial bodies near him, if our earth is very close to him, it is likely to be swallowed by it, but because we are far away from the black hole, it has far exceeded its principle gravitational range, so our earth is relatively safe, people's understanding of the black hole is still relatively one-sided, when it comes to black holes, everyone feels that this is a very terrible weather, because it can swallow everything, but compared to us, we humans black holes are still relatively far awayWe rarely mention black holes in our daily lives, and only when the impact of black holes on us is more obvious, will we feel its existence. So he basically has no impact on our lives.

It may be because the black hole moves every year, and it swallows up the perseverance around it as it moves.

Because the attraction of black holes is so great that there is a mysterious power in it, even stars can be swallowed up.

It needs to absorb energy, how can a substance like it exist in the universe without energy? With energy, you can strengthen yourself very well.

Yes, as long as the black hole is big enough and the gravitational pull is strong enough, the black hole can swallow everything, it represents the beginning of destruction, so it can swallow stars.

I think black holes can devour stars, and once the black hole gets close to the star, the star is absorbed.

No, because stars and black holes are two different things, and they are far apart, and there is no contradiction between the two.

In the universe, a black hole is a existence that devours everything, even if the light walks near it, don't want to run away, and the black hole is also the most massive single celestial body, and the smallest stellar black hole is also three times more massive than the sun, so if a black hole swallows a star, how long does it take?

If a stellar black hole encounters a star the size of the Sun, if it is not a head-on collision (which is extremely rare in the universe), then it will take a long time for a stellar black hole to devour a star like the Sun, because the two will orbit each other under the action of gravity, and when the two are close together, the black hole will strip the atmosphere of the star's surface and swallow it up. As a result, the mass of the star will slowly decrease, and the mass of the black hole will gradually increase, but the time it takes for the black hole to completely swallow the star can take millions of years to hundreds of millions of years.

So if the two collide head-on, the time for the star to be swallowed will be greatly accelerated, but because both carry huge mass, at the moment of collision, the star will be scattered by the black hole, and a lot of material clumps will be thrown out, but the push will pass through the star while swallowing, and the core part of the star will be swallowed, and the two will leave a certain distance under the action of inertial potential energy, and then reunite together under the action of gravity, and the black hole will continue to devour the star, and so on many times. Black holes will be able to devour stars, but they will still take tens to tens of thousands of years.

Then if it is a galaxy-level black hole, the situation is different, the mass of galaxy-level black holes is particularly large, up to hundreds of thousands to tens of billions of times the mass of the sun, such as the black hole Sagittarius A* in the center of our galaxy, its mass is about 4.31 million times that of the sun, and the world diameter of the black hole has reached 44 million kilometers.

This happens about every 1,000 years near the black hole Sagittarius A, the center of the Milky Way, usually only in a few years, Sagittarius A* will swallow up the approaching star, and if the star hits the black hole head-on, then it is only a matter of a moment, but because the surface of the black hole will have the illusion of time stagnation, we will find that the star seems to be stuck there forever, but in fact it has already been swallowed by the black hole.

It depends on the mass of the black hole as a celestial body and the mass of the star, according to Newton's third law, the magnitude of the gravitational force between them determines the magnitude of the suction force, and also the distance between the black hole and the star, the longer the distance, the longer it will take to eat the star.

I think it takes a big black hole to eat a perseverance, so it must be very long, hundreds of years, tens of thousands of years.
