The Black Hole Book is not the ultimate celestial body, and black holes are not really holes , but

The gravitational field around the black hole releases energy while consuming both the energy and mass of the black hole (when a particle escapes from the black hole without repaying the energy it borrowed, the black hole loses the same amount of energy from its gravitational field, whereas Einstein's formula e=mc 2 suggests that a loss of energy leads to a loss of mass). As the mass of the black hole gets smaller and smaller, its temperature gets higher and higher. Thus, when a black hole loses mass, its temperature and emissivity increase, and therefore its mass loss is faster.

This "Hawking radiation" is negligible for most black holes, while small black holes radiate energy at extremely high rates up to the black hole's **.

Can anyone prove that the end of the timeline is a black hole ?? It's all just hypothetical and theoretical stuff, and they need prerequisites and conditions for their establishment, and of course, the total mass of matter that can now be observed and indirectly measured cannot reach the gravitational value needed to stop the universe from expanding, but if that were the case, the universe would be open.

Everything in the universe is cyclical, and the black hole eventually becomes the beginning of a new universe, how can we be sure that it is the ultimate?

Black holes are the product of the extinction of stars, so they should be considered the ultimate celestial bodies.

The universe itself is also a large black hole, a completely enclosed 11-dimensional body, and the universe at the end of the timeline will also be a black hole. Besides, black holes can also eat themselves.

There is no ultimate universe, and the universe may end with a black hole, but at the same time, it is also possible that the black hole will give birth to a new universe again.

Not necessarily, it may become a white hole.

Agree... That there is an end, and I am the end.

The black hole is not a real "Tongli Cave", but a real celestial body or star. （）

a.That's right. b.Mistake.

Correct Answer: a

On the topic of whether black holes are celestial bodies, my personal opinion is that black holes are of course celestial bodies, and "black holes.""It is the largest celestial body in the universe. Why? Because:

The universe is composed of two objectively existing natural celestial bodies, the infinite stars and their star systems and the web of the universe (black holes), and in the infinite space of the universe that is boundless, infinite and infinite matter, there are countless star systems that fill the infinite space of the entire universe.

Each star system is a natural celestial body that exists in the universe with independent periodic cyclic movement of matter, and under the influence of the magnetic field magnetism of the stellar magnetic field of each star system nucleus, the edges of all star systems are magnetic isotropic physical phenomena, which will cause the magnetic homosexual repulsion phenomenon between countless star systems and the edge of the star system in the universe, which triggers a buffer distance between the edge of the star system and the edge of the star system, and the spatial distance between the edge of the countless star systems and the edge of the star system presents a huge natural celestial body in the form of a network, which encloses the outer space between the edges of all the galaxies in the universe, is like the relationship between the pomegranate nucleus and the sac, the pomegranate nucleus is the star system, and the pomegranate sac is a reticulated celestial body.

On the one hand, because each galaxy has the characteristics of co-rotating motion, the edge of each galaxy moves at an extremely fast speed, which will cause the reticulated objects to produce strong convection and vortex motion. On the other hand, the light and heat emitted by the main star of each galaxy are affected by the magnetic field of the star, and can only reach the edge of the galaxy, but cannot penetrate into the reticulated objects.

In this way, the reticulated celestial body will be pitch black, which is the exclusive high-speed network channel of cosmic dark matter and dark energy, which can play a protective role in the contraction and expansion changes caused by the co-rotating motion of countless galaxies in the universe. This huge network of celestial bodies that exist in the universe can be collectively called: the phenomenon of cosmic web celestial bodies.

This may be what astronomers call a "black hole" phenomenon.

So, of course, a "black hole" is a celestial body, and a "black hole" is the largest celestial body in the universe. In fact, the phenomenon of "black holes" referred to by astronomers is the phenomenon of the above-mentioned cosmic network of celestial bodies.

What kind of celestial body is a black hole?

A black hole is a celestial object with such a curvature of space-time that even photons cannot escape. A black hole is caused by the death of a supermassive star, and the core part of the star rapidly shrinks and collapses under the action of its own gravity, and finally forms a high-density celestial body. This celestial body can attract all the matter around him.

Yes. Because a black hole is a planet with a very strong gravitational pull and is made of matter, a black hole is a celestial body.

A black hole is a type of celestial body that can grow itself by devouring everything.

A black hole is a celestial body that exists in the universe in modern general relativity. 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. Thus, "a black hole is a celestial body with such a curvature of space-time that no light can escape from its event horizon". [1][2][3]

In 1916, the German astronomer Karl Schwarzschild calculated a vacuum solution of Einstein's field equations, which showed that if the actual radius of a static spherically symmetric star is less than a fixed value, a strange phenomenon will occur around it, that is, there is an interface - the "event horizon", once it enters this interface, even light cannot escape. This value is called the Schwarzschild radius, and this "incredible celestial body" was named a "black hole" by the American physicist John Archibald Wheeler.

Black holes cannot be directly observed, but their existence and mass can be known indirectly, and their effects on other things can be observed. Information about the existence of a black hole can be obtained by emitting "edge messages" of X-rays and rays from friction caused by the acceleration caused by the gravitational pull of the black hole before the object is sucked in. The existence of black holes can also be indirectly observed by observing the orbit of stars or interstellar clouds, as well as obtaining their position and mass.

At 21:00 Beijing time on April 10, 2019, mankind's first black hole** was unveiled,[4][5] which is located at the center of a giant elliptical galaxy M87 in the constellation Virgo, 55 million light-years away from the Earth and about 6.5 billion times the mass of the Sun. A shadow exists in its core area, surrounded by a crescent-shaped halo. Einstein's theory of general relativity proved to be true under extreme conditions.

The mass of a black hole is so extreme that it has a little density center near its center, which is called a singularity.

When an object approaches the singularity, a huge difference in time and gravity occurs at the slightest distance. In other words, the substance will be shattered.

To clarify, a black hole is not a hole, but a planet, and its interior is made up of distorted dark energy, which greatly distorts both space and time. When an object is shattered and falls onto a black hole, it collides with the black hole and is converted into energy and a pair of positive and negative particles. Most of the energy is used to maintain the distorted space of the black hole (the distorted space has to recover on its own), and although a very small part of the positive particles radiate out, the antiparticles collide with matter on the black hole to form energy, so the black hole is also a celestial body!!

Hello landlord.

A collective term for the various entities in the universe. Interplanetary, interstellar, and intergalactic diffuse matter, as well as various particulate radiation streams, are not usually referred to as celestial bodies.

Black holes are fully possessed of these properties.

The density is so great that light cannot escape, so it becomes invisible black, but it actually exists.

In fact, neutron stars have similar capabilities to black holes. So it's possible that it's the same object.
