It only happens once in 10,000 years, how exactly does a black hole swallow a star?

In the universe, a black hole seems to be a dark existence that swallows everything, and even light can not escape from it. The huge gravitational pull of black holes is the reason why stars in galaxies orbit around their centers, because black holes are dense regions of galaxies** and can be billions of times more massive than the Sun. They can warp time and space, using an unimaginable gravitational pull to allow dust and gas to gather around them, so that no form of radiation can escape, and of course, not even light.

What kind of existence is a black hole? Black holes are not black caves as everyone thinks they are, but clusters of matter with a huge density, and we can think of them as a planet with huge density. Black holes are the most massive single objects, and the smallest stellar black holes are more than three times more massive than the Sun.

If a black hole swallows a star, it will take a long time. It is estimated that in the Milky Way, the event of a black hole devouring a star occurs only once in 10,000 years on average, which can be said to be quite rare.

Root science research shows that more than 90% of black holes in the universe are dormant, like sleeping giants. When a star gets close to a black hole, these giants are briefly awakened and torn apart. If a stellar black hole encounters a star the size of the sun, if it is not a head-on collision, then the black hole will take an extremely long time to devour the sun, because the two will surround each other under the action of each other's gravity, and when the distance is closer, it will strip the atmosphere of the star's surface and swallow it up, the star mass will slowly decrease, and the mass of the black hole will become larger, but the time it takes to completely swallow up the star, Millions of years at least billions of years at most.

Black holes devouring stars are one of the most violent events in the universe, and while they are horrific to eat, they are also shocking. Some unsuspecting stars will wander near the black hole of the galaxy** and eventually be devoured. Black holes use their strong gravitational pull to tear stars to pieces and enjoy a feast while emitting intense radiation.

When a star approaches a black hole, some of them are briefly awakened, and the strong gravitational and tidal forces tear the star apart. In extreme cases, a black hole devours a star for ten seconds is enough.

As the star gets closer to the black hole, the black hole destroys the atmosphere around the star, tearing the star apart layer by layer.

Black holes strip away the atmosphere from the star's surface, and then gradually tear the star apart and swallow it.

Black holes have a very large gravitational pull, which sucks stars into them, even the light.

Black holes take between 1 million and 2 million years to form from the birth of stars. A black hole is a hole where there is no light to escape, so it cannot be seen from the outside. The important thing about black holes is that they are massive enough and small enough in volume that light cannot escape from them.

In the universe, stars can also have a large volume, but stars also experience lesions and death, when a dead star (here a star refers to a star with a large mass, several times to dozens of times the mass of the sun), because a star can provide enough pressure to balance gravity, which causes the star to quickly collapse inward, resulting in **, releasing huge amounts of energy.

<> to form a black hole, you have to make sure that the star is massive. During the collapse of massive stars, a large amount of matter begins to converge towards the center, and equilibrium can no longer be maintained by familiar forces, but by gravitational and repulsive forces between particles (I use common terminology, but the correct name is degenerative pressure). As the collapse process deepens, a large number of particles are compressed together, at this time the gravitational force becomes stronger, and the repulsive force slowly cannot resist the gravitational force, at this time, it is equivalent to the battery being completely squeezed, being touched together by the negative electrodes, and there is a short circuit (electrons and protons collide), and then there is a spark (**), and the power goes out (neutrons are formed, without positive and negative charges).

For stars that are not particularly massive, this process is the end of their life. But if the mass is really large and it is still squeezing inward, then the repulsive force between the neutrons (neutron degradation pressure) cannot resist the compression, and then the neutrons are squeezed, deformed, and begin to shatter into the smallest substance we know - quarks.

If the compression continues (quarks may continue to compress, but quarks are the smallest known component of matter), it will continue to shrink without changing its mass. Eventually, when the volume collapses to a large enough size, a black hole is born. If a star the size of our sun turns into a black hole, there will be ping pong balls.

That's so big (of course, the mass of the sun is not big enough to turn into a black hole).

It takes about 1 million to 2 million years for a black hole to form. This is because the process of creating black holes is very complex, and then there are certain similarities with the process of creating neutron stars, which require a very large amount of mass and energy to form.

Black holes take about 1 million to 2 million years from the date of their birth, because black holes are the remnants of many stars when they die.

Black holes were formed at the end of the evolution of massive stars over millions of years, some less than 1 million years ago.

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.

No. Some of them will collapse towards the center of the planet and become a white dwarf. And some stars will collapse into black holes and devour everything.

No, for a star to become a black hole, it needs to be of an order of magnitude in mass and volume. According to scientific observations, only stars with 7 solar masses can become black holes, and stars smaller than this mass will form white dwarfs when they die.

No. Because some stars expand into red giants when they die, they don't necessarily turn into black holes and devour everything.

Not really. Stars will remain in the universe after they die. until it is completely swallowed by a black hole. Otherwise, there will always be a universe.
