How do black holes in the sky form?

As we all know, there are a large number of stars in the universe, and in the long process of evolution, the stars will collapse and be crushed into an extremely dense celestial body. At the same time, the neutrons inside are crushed by the increasing mass, leaving an extremely dense substance. Due to its high density, any substance will be sucked into it.

This is a black hole.

A black hole is a celestial body with infinite curvature of space-time and an immeasurable gravitational expansion. It is made up of a "Schwarzschild singularity". After a massive star enters the aging period, after a period of evolution, the density exceeds a certain upper limit, and it will transform into a black hole.

We all know that in the observable universe, there are countless celestial bodies that make human beings talk about it and even frighten it; And black holes, without a doubt, are the best of them. It can be said that the existence of black holes makes many people sit on pins and needles.

After all, any technology that mankind is proud of has no power to resist in the face of black holes. A black hole is capable of devouring everything close to its Schwarzschild radius, and even photons and neutron stars cannot escape its clutches. Not to mention the tiny solar system and the Earth.

Why are black holes so destructive? What kind of celestial body is it?

The theory of black holes was first proposed by Albert Einstein in the last century. In the general theory of relativity, Einstein emphasized that the essence of gravity is the curved relationship between space-time, and from this, he deduced the existence of "black holes". A black hole is an immeasurable celestial body with infinite density, infinitely high mass, and gravitational expansion;

Inside, it's a shaped "Schwarzschild singularity". Where is the Schwarzschild Singularity? In the theory of the universe, it is its ** that has led to the emergence of the observable universe, which makes time and space infinitely expand.

Therefore, since the inside of a black hole is wrapped in a substance, the curvature of space-time around it is also quite disordered.

To an outside observer, a matter moving at the speed of light reaches the edge of a black hole and the flow of time is close to stopping. This is determined by the "Lorentz Change" effect.

In general, black holes** are associated with the collapse of massive stars. Of course, there are also medium-sized black holes that are created gradually after neutron star collisions or collapses. It is worth mentioning that particle collisions may also create miniature black holes.

Our universe originated with a black hole, a black hole from the parent universe. And the big ** is the end of the black hole in the parent universe: the white hole!

Before explaining this, let's first ** how gravity is generated, a mass object will bend the surrounding space, change the shortest route of light propagation, and cause the surrounding mass object to produce a continuous acceleration directed towards itself, so why does space distort? Let's try to imagine space as an originally flat rubber film (in fact, this film is 4 dimensions), and matter exists in the universe, just like a ball placed on this rubber film, it will press down to create a concave, this concave surface is the so-called "gravitational field", of course, the greater the mass, the deeper the pressure. Then the gravitational pull will also be greater.

Imagine if the ball was massive enough to break a hole in the rubber sheet, what would be the consequences? That is, this ball will leak out of this hole, so just at the other end of the rubber film, there will be an incredible phenomenon. A large amount of matter and energy erupts from this "singularity" until the ball falls completely into another world.

From extreme compression to extreme release. This is the universe of greatness**!

I can tell you this about this. The origin of the universe is the big **, and the black hole is the precursor of the big **. As we all know, the birth of the universe requires time, space, and energy.

In fact, space itself is a kind of substance, but space is too microscopic for us, so that we can't observe its existence, and the matter is compared to a fish, so space is like this water. As far as space is concerned, it is not difficult to find that if you combine Stephen Hawking's theory with Einstein's theory.

A black hole is not a hole, and a hole is not a black hole. is a celestial body.

Don't parrot your tongues, okay? Other people's theories can be used without thinking about them. Don't you have your own theory?

There is no conclusion at the moment, only doctrine. If anyone has evidence, it is estimated that he is an immortal who is hundreds of millions of years old.

It is speculated that black holes also evolved from stars. According to scientists' conjectures, matter will march inexorably towards the central point until it becomes a "point" with zero volume and infinite density. And when its radius shrinks to a certain point (Schwarzschild radius), the huge gravitational pull makes it impossible for even light to shoot outward, thus cutting off all contact between the star and the outside world – and the "black hole" is born.

Usually, the star originally contains only hydrogen, and the hydrogen atoms inside the star collide with each other and fuse. Due to the massive mass of stars, the energy produced by fusion competes with the gravitational pull of the stars to maintain the stability of the star structure. As a result of fusion, the internal structure of the hydrogen atom eventually changes, ruptures and forms a new element, helium.

Then, the helium atoms also participate in fusion, changing the structure and forming lithium. By analogy, according to the order of the periodic table, beryllium elements, boron elements, carbon elements, nitrogen elements, etc. will be produced in turn. Until iron is generated, the star will collapse.

This is due to the fact that iron is quite stable and cannot participate in fusion, and iron is present inside the star, which causes the star to not have enough energy to compete with the gravitational pull of the massive star, which causes the star to collapse and eventually form a black hole.

Black holes are very abstract for us, Hawking put forward the idea of black holes after it was confirmed that there are black holes, so what kind of concept is a black hole, first of all, it is caused by the collapse of the star, the star may be due to the excess of its own load, it will increase in density, decrease in volume, and the star will occur to a certain extent**,**At the same time, a black hole will be produced (I don't know why it is generated, but it is true), Then the black hole becomes larger and larger by absorbing the energy of the star and the surrounding body, and the largest black hole found so far is as large as tens of billions of suns (it seems to be proposed by Hawking), of course, you must also know that the black hole and the black hole will become a larger black hole after mixing, the black hole is actually equivalent to the digestive system of the universe, and nothing wants to escape from the palm of his hand, even a small atom will be torn apart after entering the black hole, and the chance of survival after entering the black hole is very small, which can be equal to the probability of fishing for a needle in the sea (of course, It may be much smaller), but if you survive, you will be transported to another world, which is connected by a white hole (a view supported by many scientists). And all the physical principles of our real life in black holes will fail, well, I know so much about black holes, of course, if humans can master black holes, then interstellar travel can also be realized.

Upstairs, the current theory is biased towards the possibility that a supernova may have formed a black hole. Technology is currently not available for research.

Black holes are formed when an aging star collapses.

It is formed by the star becoming a red giant, and the red giant collapsing and compressing. Sideline: The volume of a black hole is equivalent to 0.

A black hole is formed when the remains of a star 'erupt' are at least twice as large as the Sun.

In the remaining 10% of a star's life, it will gradually become hotter (and more energy will be released). Due to its own mass, it will generate a large gravitational force; As a result, a star can only rely on its own nuclear fusion to produce energy to balance its own gravitational pull. But when its own energy is used up, its own gravity becomes the dominant force, and the lack of force to compete with it leads to the collapse of the star itself, resulting in a more complete collapse (when the mass of the star is smaller, the collapse is not so complete).

A star the size of the Sun will only become a white dwarf, while a debris with more than twice the mass of the Sun will become a neutron star), thus becoming a point with infinite gravity and gravity. Any substance will be sucked in.

Brother, first of all, let me share my opinion: there are two ways for stars to develop: one is to develop into white dwarfs, which are small and medium-mass stars.

The second is the development of black holes, which are the development pathways of massive stars, and at the end of the phase, the gravitational force of mass is unequal, that is, the gravitational force is unequal (less than) the gravitational force.

Stars collapse and contract inward, which is how black holes are formed.

The creation of black holes is similar to that of neutron stars; The core of the star shrinks rapidly under the influence of its own weight, and a strong force occurs**. When all the matter in the core turns into neutrons, the contraction process immediately stops and is compressed into a dense planet, as well as the space and time inside. But in the case of black holes, because the mass of the star's core is so large that the contraction process goes on endlessly, the neutrons themselves are crushed into powder by the attraction of the squeezing gravity itself, leaving behind a matter of unimaginably high density.

The forces that arise due to the high density make it.

Any object that comes close to a black hole will be sucked into it by it. The black hole begins to devour the outer shell of the star, but the black hole cannot swallow so much matter, the black hole releases a portion of the matter, shooting out two pure energy bursts – gamma-ray bursts.

Black holes are the end of stellar life.
