Is a black hole the end of all things, and what is the ultimate fate of a black hole?

1. You doubt that this is sane.

2. Black holes are not the end of all things. Because black holes can't hold all the matter in the universe.

3. There are indeed no basic atoms in a black hole, not even hydrogen atoms; Because the gravitational pull of the black hole is too strong, it is impossible for atoms to form.

I believe that many people are like me, every time they look up at the sky, they can't help but think, what is the mystery hidden in this unreachable universe? Next, please follow in my footsteps and unlock this universe you didn't know about.

1 Theoretically, everything can become a black hole. When a star is in a near-death state, it will gather into a point where it will become a black hole, swallowing up all the light and any matter in the adjacent region of the Zhishu universe. Just reduce the size of the Sun to 6km in diameter, and the Sun will become a black hole.

2 The "most alien-like place" on Earth is the island of Socotra in Yemen, where 37% of the plants, 90% of the reptiles and 95% of the snails are unique to the island due to its long-term geographical isolation.

3 According to reasonable logical reasoning, there must be other life forms in the universe besides the earth, but there is no evidence to prove it, at least not publicly. And those planets that may have life, our habitable exoplanets, a total of 50 have been found.

4 Almost all matter (which is empty.) If all the space in the human body is drained, then the volume of all the people on the earth will be the size of a sugar cube.

My guess is that while the black hole absorbs energy, it also radiates energy to the outside, such as this head sucking and that head is released, and it may collapse, and after the density is too large, it can no longer maintain a stable state, and the energy is released instantaneously to the outside.

Landlord. Do you think there is a loss of energy when a black hole rubs against dust? The fact that a black hole can engulf even light proves that it is not an ordinary space, but something similar to a wormhole.

The density of black holes is large, but will it increase? Black holes can engulf things in the space around them. But, a black hole can only send something like a gravitational wave to something close to it

yy。I didn't study physics.

The black hole will eventually disappear and will be filled, who told him to be so good at eating!

The landlord's 2 and 3 are more reliable, but the second point still does not say the final fate of the black hole, because when the energy of the black hole to devour matter is less than the "Hawking radiation", the massive black hole will evaporate, and it is not impossible to see it as a "white hole" from another angle. A low-mass black hole will eventually produce a large number of elementary particles into space due to "Hawking radiation", which looks more like a "white hole". Of course, one of the expressions of "black hole-white hole" integration is like this, and the other is that black holes are connected to extremely distant "white holes" through wormholes (Schwarhis' throat), or to "white holes" in other infant universes through wormholes.

Both of these situations may exist at the same time, but we may never have the opportunity to see the "white hole", because in the later stages of the universe, no life forms are allowed to exist, and secondly, as for the "white holes" of other universes, we cannot go either, because we cannot get out of our own universe.

Black holes are a special type of celestial object predicted by the general theory of relativity. Its basic feature is that it has a closed horizon. Anything, including light, will be swallowed up as soon as it comes within horizon.

The concept of a black hole first appeared in 1798, when Laplace, based on Newtonian mechanics, calculated that a celestial body 250 times the diameter of the Sun and the same density as the Earth would have enough gravity to capture the light it emitted and become a dark object. In 1939, Oppenheimer proved based on the general theory of relativity that an unpressured sphere can collapse to the point of attraction when the mass m of the celestial body is greater than the critical mass mc under the action of its own gravity, it is impossible to reach any steady state after the gravitational collapse, and can only form a black hole. The black hole has only three characteristic quantities, which are mass m, angular momentum j and charge, the black hole is axisymmetric Kerr black hole, and the black hole at j=q=0 is a spherically symmetric Schwarzschild black hole.

In 1974, Stephen Hawking demonstrated that black holes have thermal radiation corresponding to their temperature, known as the emission of black holes. The greater the mass and the lower the temperature of the black hole, the slower the emission process will be, and vice versa. The search for black holes is an important topic in contemporary astronomy.

Stellar black hole candidates in the Milky Way include Cygnus X-1 and others. Astronomers have also discovered that large galaxies often contain a giant black hole with a mass of more than a million suns hidden at the center. For example, at the center of the supergiant galaxy M87, there is likely to be a black hole with a mass of 3 billion suns.

It is small in size, but surprisingly dense, with tens of billions of tons or more per cubic centimeter. Due to its high density, the gravitational pull is also particularly strong. No matter what you suck into it, don't even think about "crawling" out, even the fastest light can't escape the huge gravitational pull of the black hole.

Since black holes themselves do not emit light, they cannot be seen with any powerful telescope. Despite this, most scientists believe that there are many black holes in the universe. When massive stars evolve to old age, they may collapse into black holes after supernova explosions.

In the early days of the universe, some small black holes also formed. The size of a small black hole is only the size of an atomic nucleus, the mass of a mountain is about the same as that of a mountain, reaching hundreds of millions of tons, and the energy contained in it is equivalent to 10 large power stations. The black hole is like a mystery, and no one can see it.

But the powerful attraction of a black hole affects nearby objects, which emit X-rays or rays as they are attracted and engulfed by the black hole, and once they fall into the black hole, they disappear without a trace. It was by observing these rays that scientists discovered the clues of black holes. For example, the companion star of Cygnus x-1 may be a black hole.

There are also scientists who believe that there is also a huge black hole at the center of the Milky Way.

Personally, I think that it is necessary to distinguish between black holes and singularities first.

A black hole is first and foremost a gravitationally large enough object to escape from its surface at a speed greater than the speed of light. A singularity, on the other hand, is an infinitesimal point with a full latitude.

Black holes don't have to be singularities. Even, black holes can be very large. Through the calculation of gravitational force, it can be found that as long as the volume of a celestial body with a certain density is large enough, the escape speed of the surface of the celestial body will also exceed the speed of light.

Of course, a celestial body that escapes faster than the speed of light must have a gravitational pull large enough to crush the repulsive force between any particles of matter. In other words, any black hole will inevitably collapse eventually, and it will inevitably collapse into a singularity. But it takes time to collapse.

The most typical example is our universe, which is based on the idea that the universe was born from a big one, and that there are two possibilities for the fate of the universe. If the density of matter in the universe is less than the critical density, the universe will expand indefinitely, and if the density of matter in the universe is greater than the critical density, the universe will eventually shrink.

Then we can find that because the expansion rate of the universe is close to or reaches the speed of light, then if the density in the universe is large enough that it will eventually collapse (just for example, our universe may not seep like this), this means that the "escape speed" of the universe must be greater than the speed of light. It is clear that the universe itself is a black hole, a black hole that is expanding, but will eventually collapse into a singularity. We live in this black hole.

So. We can now think about it the other way around. Could there be a universe inside a black hole? Or can a singularity accommodate a universe?

The singularity is a point that both exists and does not exist in physics, externally it is infinitesimally small, but internally it has a complete dimension of space and time. We say that the universe is the sum of time and space, and for the singularity, it is also the sum of space and time. Therefore, the singularity can fully accommodate infinitely complex structures and information.

And the black hole itself has a huge amount of energy and matter.

So is it possible for a black hole to form a universe? Or is it possible for black holes to form universes that are both infinitely small and infinitely large?

All things are born and die, and black holes are no exception, although it is angry in front of us humans, but when the catastrophe comes, it still has to return to the Western Elysium. The question is, how exactly do black holes destroy?

According to Hawking's theory, in quantum physics, there is a phenomenon called the "tunnel effect", that is, although the field strength distribution of a particle is as strong as possible in places with low energy, even in places with fairly high energy, the field strength will still be distributed. According to Hawking's radiation theory, the particles that go out carry energy. The end result is that, as Hawking said in 1974, black holes will shine brightly, shrink in size, and even **.

The entire scientific community was shaken at the time.

Black holes were once thought to be the final precipitation of the universe: nothing escapes them, they swallow gas and stars, and their mass increases, so that the size of the hole only increases. Hawking's theory is a leap of thought governed by inspiration, and he combines general relativity and quantum theory.

He found that the gravitational field around a black hole releases energy while consuming both the energy and mass of the black hole (when a particle escapes from a 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=mc2 shows 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 **.

In contrast to shrinkage, the boiling theory holds that all black holes evaporate, but that large black holes boil more slowly and their radiation is so weak that it is difficult to detect. But as the black hole gets smaller, the process accelerates to the point where it eventually spirals out of control. As a black hole shrinks, the gravitational pull also steepens, producing more escaping particles and more energy and mass to plunder from the black hole.

The black hole shrinks faster and faster, prompting evaporation to become faster and faster, the surrounding halo becomes brighter and hotter, and when the temperature reaches 1015, the black hole will be destroyed in **.

Either way, at least we humans are safe for now. Although a black hole has no specific shape, you can't see it, you don't know when it will visit Earth, and you can only judge its existence based on the direction of the surrounding planets. Even if it had an effect on matter very close to Earth, we would have had enough time to save it, because its "official boundary" was still far away.

Moreover, most of the stars will become neutron stars or white dwarfs after they collapse, and this unfortunate thing may not happen to the earth. Black hole.
