Black holes have two basic parts: the singularity and the event horizon. The event horizon is a "no-return point" around a black hole, which is not a physical surface, but a sphere around the black hole, marking a location where the escape velocity is equal to the speed of light.
At the center of the black hole is the gravitational singularity, which is a one-dimensional point that contains a huge mass in an infinitesimal space, the density and gravitational force become infinite, and the space-time curve is infinite. Event horizon refers to the fact that once an object enters the interior, it will be attracted to the center. Under such a strong gravitational pull, the matter is compressed to a point, a small volume, but extremely dense.
This point is called the singularity. It's small, so it actually has infinite density. <>
According to the "cosmic check" hypothesis, the singularity of black holes has always been hidden behind their event horizon because black holes are always surrounded by regions that do not allow light to leak and therefore cannot be directly observed. Suppose the only allowed exception (known as a naked singularity) is the initial large ** itself. Well, by its very nature, it seems that we will never be able to fully describe or even understand the singularity at the center of a black hole.
Although an observer can send signals into a black hole, nothing inside the black hole can communicate with anything outside the black hole, so its secrets seem to be always safe. <>
Astronomers don't see black holes directly. Instead, astronomers observe the presence of a black hole through its effects on the surrounding environment. At the center of our galaxy, a black hole itself is very difficult to detect.
Studying black holes relies heavily on indirect detection. Astronomers see the behavior of other objects, which can only be explained by the presence of a very large and dense object nearby. These effects may include matter being pulled into a black hole, forming an accretion disk around the black hole, or a star rotating around a huge but invisible object.
Traditionally, astronomers have divided black holes into two basic types: stellar-mass black holes, which are about 5-20 times the mass of the Sun, and masses, which are millions to billions of times the mass of the Sun, called supermassive black holes. A stellar-mass black hole is formed when a large number of stars run out of fuel and collapse.
Almost every large galaxy has a supermassive black hole at its center, and how exactly supermassive black holes form has always been an active area of astronomers. Recent studies have shown that the size of black holes is related to the size of galaxies, so there must be some connection between the formation of black holes and galaxies.

It is both a singularity and a planet, it is only a very dense planet, so the mystery there is very high, and the scientific community has not yet studied it.
-
Black holes are still an unexplored cosmic mystery, and objects near black holes will be swallowed without exception, so there is no way to tell whether a black hole is a singularity or a planet.

Heavenly body. Because a black hole is a celestial body with a lot of density and gravity, and there is only one singularity, a black hole is not a singularity, but a planet.

If two fiery liquid stars collide plastically, the high-temperature luminous material flow will gradually transition from an irregular ring to a perfect circle. And the center of the flow of matter must be empty, this existence of nothing, some people call it a black hole. The star is like a tire.
That's just a flow of matter! There's a lot of room at the edge. If something similar happens in the solar system, it may at least involve the radius of the Earth's orbit.
The flow of matter and the envelope means the flow of plasma, and the flow of plasma, which means the current, necessarily manifests itself as an energetic manifestation of angular momentum. That is, the axial particle flow representation. At the end of the day!
The so-called black hole is the diversionary vortex of the material cavity where the stars collide. There was nothing strange about hunting originally! It is a common astronomical phenomenon in the universe, but it is only novel because of the part of human vision and the possession of vision!
It can't prove that anyone is huge, and it can't get the back door of the universe. Science is science, and science cannot be absolute! This is the fact that astronomical phenomena are meant to inform people.
If it can be absolutely, it is still clear that the solar system is more objective, but unfortunately, even if the solar system is not clear, it is true that tens of millions of light years away!
It is neither a ball nor a hole, but it has the properties of a celestial body, such as angular momentum, mass, and also has the properties of a hole. In addition, the black hole is usually referred to as the singularity inside the black hole plus the space within the surrounding event horizon, which is not the Schwarzschild radius but the event horizon, because the Schwarzschild black hole is only the simplest theoretical black hole. You can think that the inside is empty, because the line will be sucked into the singularity, and you can also think that there are many things inside, because there is no falsification anyway, you can say whatever you want; It is also possible to think that there is no interior at all, because all the information about the black hole is revealed to the outside.
In short, astronomically, a black hole is a celestial body, and if we use an analogy, it is not impossible to think of a black hole as a hole. How does a speck of dust become a planet, then you have to ask the black hole, and if the black hole has an inlet, there must be an exit. Whether this exit is dust or a supernova, it's all karma.

The black hole is not a planet, it is a singularity in the universe and everything changes; According to the current black hole theory, there is a singularity with infinite density and mass at the center of the black hole, so the singularity must be defined before a black hole can be defined.
-
Quite possibly a planet. The interior of a black hole is highly attractive, and it may be related to slip and the recession of celestial bodies. The causes of black holes are very complex, but Laughnara only knew that the planet would die slowly.

I think it might be a singularity to grip him roughly; Because this singularity contains a large amount of black hole matter, and it has almost no big or small hand talk, the mass can be infinitely compressed, and the density can be as large as the stool touches.

In the universe, if there is something that is certain to exist and has mysterious overtones, it must be a black hole.
To put it simply, a black hole is an extremely aggressive and mysterious celestial body. The mystery of a black hole is that no one knows its internal structure, and the aggressiveness of a black hole lies in the fact that everything around the black hole is swallowed by it, even light.
Black holes were first discovered by a German astronomer, and the discovery of black holes by this astronomer is inseparable from Einstein's contributions to astronomy.
Newton believed that inertia is a property of an object, and the greater the mass of the object, the greater the inertia, i.e., mass is the physical quantity that describes the magnitude of the object's inertia. Newton's first law states that the inertia of an object does not change due to changes in the state of motion of the object, i.e., the law of invariance of inertia. This law was considered absolutely true for a long time.
It was not until the end of the 19th century that scientists discovered that the phenomenon of microscopic particles moving at high speed could not be explained by classical mechanics, and people began to doubt the correctness of classical mechanics.
At this time, Einstein proposed the special theory of relativity, and he pointed out that when an object moves at high speed, the mass of the object increases with the increase in speed. After this, he proposed that mass and energy can be converted into each other, i.e., energy is equal to mass multiplied by the square of the speed of light. This means that for an object with mass to reach the speed of light, the energy required would need to be close to infinity.
Therefore, an object with mass does not reach the speed of light.
When the first cosmic velocity of a celestial body reaches or exceeds the speed of light, the object can capture all the objects around it. Even light can be caught. This type of object is what we call a black hole.
It is not that a black hole will shrink into a singularity, but that when a massive star gravitationally collapses to form a black hole, its matter will collapse into a point of infinite scale and infinite density, called a "singularity". I don't know if the singularity is real. The formation of the singularity is just a corollary of the theory of relativity. >>>More
The Schwarzschild radius is based on the Schwarzschild gauge, which is defined as a space-time gauge with a vacuum static spherical symmetry and a zero energy momentum. >>>More
No way. A black hole is not a hole, but a very tiny sphere, very dense, and rotates, the object attracted into it is compressed into a part of itself, and eventually the gravitational force is too great, and it will be ** once, become energy or stars, and the spacecraft will fly into it will be pulled into itself thousands of times longer because of the gravitational difference, and then compressed into a part of the black hole. The wormhole is the passage to the parallel universe, but you can't touch the edge when you pass through, otherwise it will be crushed by the parallel universe, unlike the black hole, the wormhole is a hole blasted out with high energy, but, who knows, maybe the power of our bombardment will destroy the universe, and it is not enough to penetrate the four-dimensional space to create a wormhole.
A black hole is actually a very massive and dense celestial body. Due to its mass and density, its gravitational pull is so great that light is gravitationally bound on its surface. Because the light is bound to the surface and cannot be reflected, we cannot see it in the visible range, so it is called a black hole. >>>More
If the universe is a living being, human beings should not be fooled by cells, which should be planets and stars in the universe, and human beings are at most a small part of the cytoplasm of some cells (the earth).
