Is a black hole a hole or a planet like celestial body?

How do you know if a black hole is a hole or a planet-like celestial body?

It is a celestial body like a star.

In the vast universe, there is no more unfathomable celestial body than black holes, and scientists can basically say that there are only a handful of data and information about black holes and their related professional knowledge. What is a black hole called? The black hole is often called a black hole, the key is that because the gravitational pull of the black hole is extremely large, all objects and chemicals that want to get close to or close to him will be digested and absorbed, and even light cannot break free from his "clutches", so everyone habitually calls him a "black hole".

At the same time, the All-Seeing Glasses Agency, a well-known international organization in Eastern Time, released the first black hole photos in Washington, D.C., Amsterdam, Denmark, and other parts of the world. This photo is very hard to come by, and it consumes a lot of human resources, material resources and funds, <>

The discovery of this effect not only caused a great shock to the astronomical community, but the whole world rejoiced at it. This photo of a black hole is not only a photo, but also a confirmation of people's exploration and discovery of unknown cosmic space, and at the same time represents Newton, a scientist close to God, who has once again succeeded in speculating on the objective fact that black holes have been discovered by people. According to the current scientific research, it can be grasped that the indoor space inside and outside the all-seeing has the characteristics of exchange, which is <>

The orientation of the inner and outer indoor space may be confused, that is, if it is not good to be attracted by the black hole, then this chemical will inevitably fall into the singularity of the management center along a direction called time, that is, the unique point of r is 0, this r is not the other r, and the singularity of r is 0 is not the point that everyone often says that the semi-longitude r is 0, but the point of time, that is, the end of time. The situation outside of a black hole is very different. Which ones are also singularities?

The basic theory of singularity is a new and upgraded basic theory clearly put forward by the well-known British scientist Donovan Kurzweil, and "singularity" was originally used as a technical term in astrophysics, which roughly means "a point that is not suitable under the standards of general physics in the vast space".

The so-called black hole is actually the collapse of the planet, and the final formation of a planet with great mass and great gravity is called a black hole because the gravitational force is so large that light is attracted.

In fact, it is a planet-like celestial body, which led to the discovery that black holes are a special substance that can cause serious effects.

Of course, it is a celestial body like a planet, and the reason why it is known is because people discovered it when they observed it with astronomical telescopes.

It should be a celestial object, because we have now photographed some ** about it one after another, and our understanding of it has gradually deepened.

According to current scientific research, a black hole is a sphere. But according to Einstein's theory, it is also possible that a black hole is a hole, which is used to lead to another cosmic space.

Is a black hole a hole or a celestial body like a planet? On what basis? A black hole is a celestial body like a planet.

A black hole is currently thought of as a point or ring where light cannot reach a certain distance around the observer, called the event horizon, giving the illusion of a black hole. Singularities or odd-numbered rings do not have volume. A black hole is not a black hole or a star, nor is it a nova or supernova.

Black holes are impenetrable. Mathematically, the mathematical behavior of the Cauchy Horizon through a Kerr-Newman or Kerr black hole is similar to entering a parallel universe, but almost nothing. As scholars in the field have described in the United States**, any attempt to do so outside the confines of existing physics is likely to be a complete failure.

<> a traveler approaching the Cauchy horizon could be killed by an elephant galloping at speed in front of him. Tidal forces crush an object through a gravitational gradient at both ends of the object, which is something that any object large enough can do. They are not special and are not unique to gravity.

In the vicinity of the event horizon of a supermassive black hole, the tidal force is not noticeable, and observers cannot see it smashing objects through this action. The central region of the Sun is currently thought to be above 15.71 million degrees Celsius, and there may be organisms that can survive in such extreme environments, but they are very different from life on Earth.

We all know gravity, but gravity is a very weak force, and you can also jump up, or fly into the sky in a plane. But your freedom is only temporary. Objects usually fall back after leaving the ground, unless you exceed a certain speed.

If you can jump off the ground at a speed of 11 kilometers per second, you can escape the gravitational pull of the Earth. Scientists need at least this escape velocity to launch a vehicle into space. The larger the object, the tighter the material and the faster it can escape.

Their escape velocity increases from Jupiter and the Sun to white dwarfs and neutron stars. However, the core of the largest star collapses to form an extremely dense object called a black hole, which escapes faster than the speed of light.

When it comes to the word black hole, many people may have a misunderstanding, because although a black hole has a hole word, it is not a hole, it is not a planet, but a very special celestial body!

Why are black holes special?

The black hole can be said to be the most terrible celestial body in the universe, and it is also the most dense celestial body known, its gravitational pull is extremely strong, so strong that even the surrounding space-time has a strong bending phenomenon, we know that space-time curvature is a manifestation of gravity in the general theory of relativity, that is, the greater the mass of the object, the stronger the space-time curvature, for example, our sun will cause a slight bend in the surrounding space-time, which causes all the celestial bodies in the solar system to rotate around it, and the space-time curvature caused by the black hole is extremely large, This causes it to escape faster than the speed of light within its event horizon.

As long as any object enters this range, it is swallowed by it, so we cannot directly observe the black hole, but can only find it indirectly, such as when a celestial body is moving around a gravitational source that we cannot see, or when a black hole is devouring the accretion disk created by the substance, we can find the existence of a black hole!

So how do black holes form?

Black holes generally collapse after the death of stars, and they are similar to the generation mechanism of white dwarfs and neutron stars, which are the products of the end of stellar evolution, but black holes are formed after the death of supermassive stars.

We know that the reason why stars can shine and heat depends on internal nuclear fusion reactions, they will carry out nuclear fusion step by step, and the nuclear fusion of a massive star will eventually stop in the iron element, because when the massive star fuses to the iron element, it can no longer carry out nuclear fusion to release energy, so the inner core begins to collapse due to its own gravitational effect, and then triggers a supernova explosion, at this time, the inner core of the star will be ruthlessly squeezed, electrons are pressed into the nucleus, and the homoprotons are combined into neutrons. If the inner core of a star is lower than the mass of the sun, then the inner core will form a neutron star made of neutrons, and if the inner core mass is higher than the mass of the sun, that is, the Oppenheimer limit, then the core will crush the neutrons into powder, and eventually become a terrible black hole from which no light can escape.

If such a terrible black hole were to come close to Earth, it would be devastating. Once on Earth, the atmosphere is stripped away and then torn apart by a strong gravitational pull until it is sucked into the interior of the black hole.

It is worth mentioning that in fact, not only stars will form black holes, in fact, any object can become a black hole, in 1916, German astronomer Carl Schwarzschild calculated Einstein's gravitational field equation, obtained a vacuum solution, this solution shows that when an object is continuously compressed, reaching its critical radius eigenvalue, it will collapse into a black hole, and this critical value is called Schwarzschild radius.

If we were to compress the Sun, his Schwarzschild radius would be only 3 km, and the Earth would be only 9 mm.

It is neither a hole nor a planet, a black hole is a very special celestial body.

No one has yet been able to fully solve the mystery of the black hole, it is neither a hole nor a planet, it is a mysterious force.

According to astronomical research and astronomical records, a black hole is not a hole, but a planet, and some knowledge about black holes is worth exploring.

A black hole is a very massive, but very small, swirling celestial body, which is able to see through all objects around it, including light, other planets, and some larger black holes are capable of swallowing stars at the same time.

A black hole is a very dense celestial body, very large in size, and also has a strong attraction that can absorb a lot of light and matter.

A celestial body that can absorb things, this kind of black hole is also formed after **, the suction of the black hole is very large, and it can absorb a lot of things.

It is a very mysterious celestial body that can suck all the matter around it into its own hole, and the gravitational pull is particularly strong.
