A black hole is a celestial body with such a curvature of space-time that no light can escape from its horizon, and all physical theorems fail when it encounters a black hole. Black holes are created by the gravitational collapse of massive stars (at least 10 times the size of the Sun) after they run out of fuel for nuclear fusion reactions. The mass of a black hole is so great that its gravitational pull is so strong that any matter and radiation (including light) that can no longer escape from a black hole within one of its event horizons (critical point).

Usually, the initial content of a star is only hydrogen, and the hydrogen atoms inside the star collide with each other all the time, fission and fusion occur. Due to the large mass of stars, the energy produced by fission and fusion competes with the gravitational pull of the stars to maintain the stability of the star structure. As a result of fission and fusion, the internal structure of the hydrogen atom eventually changes, ruptures and forms a new element, helium.
Then, helium atoms are also involved in fission and fusion, changing their structure to form 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 fission or fusion, and iron is present inside the star, causing 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.

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.
-
What makes a black hole special is that it looks dark because light can't escape its strong gravitational field. Such a strong gravitational field stems from a supermassive mass, and only a star with such a massive mass (about 30 solar masses) can become a black hole.
-
Matter will march inexorably towards the central point until it becomes a very small volume and tends to be very dense. And when its radius shrinks to a certain point (it must be smaller than the Schwarzschild radius), as we described above, the huge gravitational pull makes it impossible for even light to shoot out, thus cutting off all contact with the star from the outside world - a "black hole" is born.

It can only be said that the origin of the galactic galaxy in one cosmic galaxy: the initial heavy particles and heavy matter move in one direction, due to the accumulation and sedimentation of heavy matter into a super-aggregate, the internal ultra-high temperature, the reaction eruption produces light matter and the original light matter spreads outward. The heavy matter of the superpolymer gradually turns into light atoms and escapes outward.
The internal collapse eventually turns into a high-speed rotating black hole, and the matter body rotates and rubs under the action of gravitational waves, forming planets with different specific gravity. The centripetal force of the cantilever rotates to form the first billions of small galaxies. It is the formation of the solar system.
In the solar system, the temperature of the complete combustion of the sun is very high, most of the interior of Mercury is very hot, and a small part of the interior of the earth is warm, and the outer planets of the earth in the solar system will be lighter and colder. Talking about the mass of the atom, there is a lightest nucleus without neutrons, and the more neutrons inside, the heavier the atom. Let's say that the rotation of the center of the Milky Way is determined by the magnetic field and the gravitational or repulsive force of the adjacent super-large galaxies.

There may be a celestial body with a large mass and a small radius, such that it escapes from it at a speed of light. In other words, the gravitational pull of this celestial body is so strong that even 300,000 kilometers of light per second is pulled by its gravitational pull and cannot escape. Since the light of this celestial body cannot escape, we can't see it, so it is black.
-
Since the density of a black hole is extremely large, according to the formula we can know the density = mass volume, in order to make the black hole density infinite, then it means that the volume of the black hole should be infinitely small, and then the mass should be infinite, so that it can become a black hole.
-
Like white dwarfs and neutron stars, black holes may have evolved from stars with masses 20 times the mass of the Sun.
-
Light is the fastest in the universe, and it is impossible for any matter to move faster than the speed of light. Since light cannot escape from such celestial bodies, of course no other matter can escape. As long as everything is sucked in, it can't come out again, it's like falling into a bottomless pit, such a celestial body, people call it a black hole.
-
A black hole can be understood as a dead star formed by the "extinction" of some stars, all of which are large in mass and small in size.
-
An energy ball burns, and after burning, the energy is concentrated, forming a very small singularity, small in size, and the gravitational force increases geometrically, so that even light cannot escape, forming a black hole.
-
I know, but can I say it here? To casually say that it is a disparagement of science and a sign of disrespect for the fruits of labor. It can only be said that the supernova explosion of superstars in the later stage of supernova is a possible product, which is the consensus. Other arguments at this stage may be incomplete or problematic.
-
A product of the operation of the final galaxies.

According to the solar system, people have never flown out of the solar system, and the black hole is the entire outer space, and it is still a mystery whether parallel worlds exist or not!

I have discovered the positive and negative horizons, the unity of forces, and the optoelectronic nature with the method of switching perspectives.

It's very powerful, but it can't occupy the entire universe.

A black hole is formed by a collapse caused by the rapid clumping of matter together and compression. Strange celestial body, this field its gravitational pull and very large. Not even the light could escape his palm.

Different neutron stars collide under the action of simple state pressure.

How the earth came to be has not been figured out.

There are many reasons for the formation of different black holes, but here is just one example for reference:
The creation of a black hole is similar to that of a neutron star: when a star is preparing to perish, the core of a star rapidly shrinks and collapses under the force of its own gravity. When all the matter in the core turns into neutrons, the contraction process immediately stops, and it is compressed into a dense star, which also compresses the space and time inside.
But in the case of black holes, the mass of the star's core is so large that the contraction process goes on endlessly, and even the repulsion between neutrons cannot be stopped. The neutrons themselves are crushed into powder by the attraction of the squeezing gravity itself, leaving behind a material of unimaginably high density. The gravitational pull due to the high quality is such that any object that comes close to it will be sucked into it.

Scientists have long discovered how black holes build planetary ice to determine their future. But there is still a big unsolved mystery, that is, what does a black hole look like at its deepest point? Black holes were previously just a basic theory, an inference made by Einstein.
We now know that they control the planets and are capable of creating the brightest light in the universe, but they still have a mystery that even Newton could not have anticipated. What would happen if we could go into the event horizon? The boundaries of this black hole's outfield cannot be escaped even by light.
We already have a certain grasp of the black hole's outfield, but what we don't know is that the last moment, in fact, is what will happen if you raise the horizon of time.
For us, it's uncharted territory where you can use the expertise you already have to make breakthroughs. The scientist Fei Qio does not need glasses, he is not an astronaut, he wants to produce black holes in his laboratory, and the main element he uses is light. Fei Qi Olympics used a super powerful laser to force the light to react, and gradually flowed like a liquid.
In the vicinity of the black hole, the indoor space will also flow towards the event horizon like a liquid, such as the super-midstream and downstream mobility of a river. Imagine walking against the current in the flowing water and you will feel the river dragging you away. This is how the gravitational field of the black hole's outer field works.
Fezio forced light to produce tight vortices, like black holes in the true sense of the word, but he also achieved breakthrough scientific results. When he shot a microwave into his own black hole, a wonderful phenomenon occurred, the microwave did not move at all, it was basically stationary, and it stopped in the field of vision of the time he was making. Those motionless microwaves validate the inference of the most famous fundamental theory, which is quantum theory.
When approaching a super-black hole, the force begins to grow longer, and a second will seem like years or centuries, and from a distance, the object's own time seems to stop, as is common in experimental super-black holes, and he believes that the same is true of super-black holes in the universe. Let's say you see a spaceship or someone else falling into a black hole in the distance, and you can actually never see that person through the event horizon of rebirth, you will see them coming closer to the event horizon, but in the eyes of everyone, they have slowed down, and we will see them become a little slower, and then they will stay still in the event horizon.
But the astronauts in the spaceship don't easily feel the time being lengthened, and the force they feel is consistent with the surrounding environment, for them, the speed of time change is still normal, and the force increases their time horizon, even Newton doesn't know what will happen next. But Figeo thinks that its experiments will one day solve this scientifically reasonable mystery, and Figeo feels that a new physical law is in a black hole, but it is currently unknown, and the other end of the event horizon is still a mystery.
-
A black hole actually refers to the event horizon that wraps around the singularity. The event horizon is the boundary of a black hole, and any matter or energy that enters this boundary can never leave this range.
-
A black hole is a celestial body that exists in the universe, and the gravitational pull of a black hole is very huge.
-
A black hole is a type of celestial body that exists in cosmic space. The gravitational pull of a black hole is extremely strong, allowing the escape velocity within the event horizon to be greater than the speed of light. Therefore, black holes are also described as celestial objects with such a large curvature of space-time that even light cannot escape from them.
The black hole consists of a scalar polynomial in the center constructed from the Riemann curvature tensor at the singularity that converges here and the surrounding space-time, and its boundary is a one-way membrane that only enters but does not exit: the event horizon, which is not visible within the range of the event horizon. According to Einstein's theory of general relativity, when a dying star collapses, it will collapse toward the center, where it will become a black hole, swallowing up all light and any matter in the adjacent universe.

Theoretically, black holes exist. A black hole is a place where light can't reach. So all you can see is a black mess there. What exactly. Scientists don't know either.
Black holes may be the most mysterious place in the universe, since the black hole theory was proposed, Einstein and Hawking have affirmed the existence of black holes, and the vast majority of scientists are committed to finding evidence of the exact existence of black holes to improve the black hole theory, NASA even wants to do a "census" of nearby black holes. However, a group of American scientists have recently put forward a completely new view, holding that the so-called black hole is completely imaginary.
Black holes do not allow anything within their boundaries to be seen by the outside world, which is why such objects are called "black holes". We cannot observe it through the reflection of light, we can only know about the black hole indirectly through the surrounding objects affected by it. That being said, black holes have their boundaries, the "event horizon" (event horizon) and it is speculated that black holes are remnants of dead stars that are created when a special massive supergiant collapses.
In addition, a black hole must be formed by a star with a mass greater than the Chandrasekhar limit at the end of its evolution, and a star with a mass smaller than the Chandrasekhar Leakage Limit cannot form a black hole.
A particularly dense dark object predicted by the general relativity theory of black holes. Massive stars collapse at the end of their evolution, and their matter is so dense that it has a closed boundary called the "event horizon", and the black hole hides a huge gravitational field that is so strong that any matter, including photons, can only enter and cannot escape. The lower limit of the mass of the nucleus of the formation of a black hole is about 3 times the mass of the sun, which, of course, is the mass of the last nucleus, not the mass of the star in the main sequence period.
In addition to this stellar black hole, there are other black holes - the so-called miniature black holes may have formed in the early universe, and the so-called supermassive black holes may exist in galaxies**.
A black hole is actually a planet, but it's so dense that everything near it is confined by its gravity (as if a person hadn't flown away on Earth). For the Earth, it is possible to escape from the Earth by flying at the second cosmic speed, but for a black hole, its second cosmic speed is so great that it exceeds the speed of light, which is already the limit speed. So we can't even get the light out, so the light that comes in is not reflected back, and our eyes can't see anything, it's just black.
-
The existence of black holes is not certain from ignition, and many people believe that black holes do not exist; The reason why it is believed that it does not exist is because Einstein proposed that black holes are only a theory of relativity, not a period of staring at some exact representations, and a famous scholar at that time, Stephen Hawking, also showed that black holes do not exist, and at present, there is no way to explore whether black holes exist with human technology.
I think money is a necessary tool for people's lives, and it takes money to buy and sell something, and money certainly needs some normal channels to obtain.
How are black holes formed?
The creation of a black hole is similar to that of a neutron star: the core of the star contracts rapidly under the influence of its own gravity, resulting in a strong force**. When all the matter in the core turns into neutrons, the contraction process immediately stops, and the star is compressed into a dense star, as well as the space and time inside. >>>More
Friend Sang, has taken the driver's license twice. Once was in the university and classmates to apply for a driving school outside the school, when signing up, "chartered car pick-up, 3 months to get the certificate" The beautiful words are very deep, and after paying the money, they immediately turned their faces and did not recognize people, and finally had to embark on the road of rights protection, and simply returned the money, and the ending was at least positive.
