What conditions must be met for a black hole to form 20

A black hole is formed when the remains of a star 'erupt' are at least twice as large as the Sun.

In the remaining 10% of a star's life, it will gradually become hotter (and more energy will be released). Due to its own mass, it will generate a large gravitational force; As a result, a star can only rely on its own nuclear fusion to produce energy to balance its own gravitational pull. But when its own energy is used up, its own gravity becomes the dominant force, and the lack of force to compete with it leads to the collapse of the star itself, resulting in a more complete collapse (when the mass of the star is smaller, the collapse is not so complete).

A star the size of the Sun will only become a white dwarf, while a debris with more than twice the mass of the Sun will become a neutron star), thus becoming a point with infinite gravity and gravity. Any substance will be sucked in.

And because of its gravitational pull, even the fastest light in the universe can't escape. So, if the light is not reflected, we can't see it. Therefore, it is called a black hole.

A star has to be more than 20 times the mass of the Sun and collapses into its Schwarsiz radius on its own, allowing a black hole to form.

Essentially, as long as there is a singularity, there is a black hole. A black hole is the "escape radius of light" of the singularity.

The greater the gravitational pull of the singularity, the larger the black hole, i.e., the greater the distance of light, it cannot escape.

The formation of a black hole is the formation of a singularity.

There are three main known types of formation mechanisms:

1. Giant star collapses.

2 particle collisions.

3. The primordial black hole of the universe (that is, the cosmic core that has not yet been **, is caused by the inhomogeneity of the universe).

Black holes can be created by humans, and the current experiments on the High Energy Particle Collider can theoretically produce ultra-small black holes, which exist for the same time as Planck time.

The same length, almost no mass, no means of observation, no impact on the world. It is clear that such a black hole is a black hole that has no meaning. The main intent of the question should be whether humans can create black holes for human use.

We can't make natural black holes in the universe, the stars are too big, and secondly, we can't make ultrasmall black holes for high-energy physics, because it doesn't make sense.

<> the birth of a black hole needs to conform to the Schwarzschild radius formula, for example, if you put the Himalayas.

Compressed to the size of a pencil, a black hole will appear, and it is clear that in the future humanity needs to be in the asteroid belt.

To make a black hole factory, first capture enough mass, then accumulate energy for pressurization, and finally through the method of **, for example, the size of the collective mass of igniting a black hole is also particular, and the black hole Hawking radiation studied by Hawking tells us. The smaller the mass of the black hole, the greater the Hawking radiation, and the greater the mass that a black hole will radiate from the black hole, the smaller the radiation will be (presumably that's what it means, I don't remember) So, if a black hole is smaller than an order of magnitude.

The energy radiated will take away all the material on the surface, that is, the black hole closes, stops eating, and the Hawking radiation gets worse and worse, and finally disappears in **.

If a black hole is an order of magnitude larger, and you can't move it by magnetic traction or something like that, you've created something very dangerous for yourself. The meaning of black holes, the creation of black holes, can give physics a new direction of research, and if you can get astrophysicists in touch with black holes, he will definitely bleed with excitement. I think the way we can break through the speed of light is probably to study black holes, because there's nothing more distorted than a black hole.

Black Hole is the perfect waste treatment plant. They eat garbage and spit out energy, with a mass and energy conversion rate of more than 30%. Although humans can create black holes, there must be more ways to dispose of garbage, such as packing it and throwing it into the sun is also a good option.

Black holes in the future of interstellar travel.

also plays an important role.

What if we could use black holes as the core of energy? Run to a new planetary system, feed the black hole something, and keep running to watch The Wandering Earth

Heavy element nuclear fusion.

When I joked, flint.

I'm afraid it's not an electromagnetic field generator made of black holes, otherwise how can you eat stone nuclear fusion. Finally, what kind of technology does humanity need to make black holes? The level of science and technology that compresses a mountain to the size of a pencil tip, artificial neutron star matter is the beginning.

Yes, you must measure the volume of the object, you should pay attention to the speed of the particle accelerator, you should pay attention to the collision between the particles and the particles, after the collision, there is a possibility that a black hole will be generated, you must go to the largest factory in the world. Be sure to pay attention to the volume of the object, the compression ratio.

Yes, if you want to make a black hole, you must compress the object to a very small size, pay attention to the collision between particles, and meet the relevant experiments of the particle collider, so that you can create a relatively small black hole.

OK. First of all, it needs to have very high-tech means, it takes a lot of time and energy, and then it also needs to be supported and recognized by relevant departments, and then it is also necessary to understand whether black holes are harmful to human beings, so that black holes can be created.

The number in the figure stands for no.

Qubit (Qubit), the smallest unit of positive and negative electromagnetic information that is revisably partitioned, is a qubit (named physicist John. John Wheeler famously said, "It from bit."

After the development of quantum information research, this concept was sublimated to the point that everything originates from qubits) Note: Bits are bits.

A black hole is formed when matter collapses faster than the speed of light, or the gravitational pull at the origin exceeds the speed of light, and even light cannot escape.

Theoretically, it is formed by super-constant **, and there are many conditions, remember that such stars are more than 10 million times larger than the sun.

Stars that exceed the Chandrasekhar limit burn up and collapse due to their own gravity.

The black hole is formed by the debris of a superred giant with a mass greater than the mass of the Sun, which is not sufficiently fueled for nuclear fusion in its later years, and its own gravity causes it to collapse towards the center, after a supernova explosion.

Like white dwarfs and neutron stars, black holes are likely to evolve from stars with masses 20 times the mass of the Sun.

When a star ages, its thermonuclear reaction has exhausted the fuel (hydrogen) of the center, and there is not much energy produced by the center. In this way, it no longer has enough strength to carry the enormous weight of the shell. So under the weight of the shell, the core begins to collapse until it finally forms a small, dense star that regains its ability to balance with the pressure.

Stars with less mass mainly evolve into white dwarfs, while stars with more mass may form neutron stars. And according to the calculations of scientists, the total mass of a neutron star cannot be greater than three times the mass of the Sun. If this value is exceeded, there will be no force left to compete with its gravity, causing another collapse.

This time, according to scientists' conjectures, matter will march inexorably towards the central point until it becomes a very small volume and a very dense tendency. 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 between the star and the outside world - the "black hole" is born.

In addition to the possible creation of black holes by the end of the star, there is also a special kind of black hole - quantum black holes. This kind of black hole is very special, its Schwarzschild radius is very small, and can reach ten minus twenty square meters, which is smaller than an atom. Unlike ordinary black holes, they are not formed by the collapse of very massive stars, but by the collapse of atoms, so there is only one condition under which a quantum black hole will be created - the big **.

In the early days of the universe, enormous temperatures and pressures compressed individual atoms or clusters of atoms into many quantum black holes. And this kind of black hole is almost impossible to observe or find, it currently exists only in theory. **。

It is formed by the collapse of a star or supernova because it cannot support itself. The gravitational pull of a black hole is so strong that it can only be freed when the object is three times the speed of light.

According to current scientists, the formation of black holes is that after the aging of the star, the energy of the entire center of perseverance is exhausted, because the energy of the whole star is not much, there is not enough strength to bear the weight, so under the weight of the planet's shell, the core of the star begins to collapse, and the material begins to migrate to the center, until finally the volume is close to infinitesimal and the density becomes very large. Scientists believe that black holes form mainly because of the changes in dead stars that occur after the lifespan of stars reaches a certain level. <>

Black hole can be said to be this century is also the current scientist is very fond of research and exploration of an astronomical knowledge, black hole formation is very complex, in the scientists' guess, the center of the black hole is an infinite density of singularity, the surrounding part is also an empty space area, the entire black hole range can not see anything, because the black hole generation process is similar to a gradual process of the transformation of a star to a neutron star, indicating that the entire star is on the verge of self-extinction, and the star is in the process of shrinking and collapsing**, All the matter in the core of the entire planet gradually turns into neutrons, such a planet with an almost infinite density compresses its own volume, and in the case of speculation by scientists, the exploration of this situation will be endless, so a huge gravitational pull will be generated to absorb all matter, even rays. <>

At present, the research on black holes is gradually inferred in the process, when people infer that there are black holes in space and various theories and knowledge about black holes are proposed, people's research on black holes has never stopped, and the emergence of black holes, the generation of black holes, and the future development direction of black holes, is also the problem that scientists have been in the first place, more and more theories have been guessed and proposed, and more and more theories have been verified and overturned, and some theories have been unanimously recognized by scientists. Therefore, the study of black holes is a topic worthy of people's attention in astronomy, and many astronomers are currently studying black holes with the progress of science and technology and the development of aerospace knowledge, which is getting faster and faster. <>

The cause of black holes generally comes from the explosion of supernovae, which occurs when the star dies, blowing up its shell and leaving a core to produce a black hole, which is a special celestial body formed after the "death" of a massive star above the critical value.

What are the causes of black holes?

A black hole, a celestial body with a huge mass and gravity, is, as the name suggests, a "bottomless pit". Since there are no photons "falling into" and no photons "escaping" in the "bottomless pit", we cannot see it. A black hole is a definition of a spatial and temporal realm whose gravity is so strong that no matter or electromagnetic radiation, such as photons, can escape.

General relativity**, dense enough to distort space and time, forming inescapable regional boundaries, the so-called "event horizon".

In short, it is here that there is no way to deliver the message. Although there is no direct observation of black holes, we can indirectly prove the existence of black holes by looking at their time and space, for example, when the black hole exerts a huge gravitational pull on nearby stars, resulting in a huge accretion disk. In this process, the star's material is heated, emitting X-rays so we can observe it.

However, it is important to know that no real black hole has been found, and there is only one similar black hole candidate.

Why do black holes exist?

A black hole is a special type of celestial body that is created after the "death" of a massive star that has passed the critical point. With the consumption of hydrogen, there is also a fusion of helium around the center of the earth. Massive stars turn more matter into iron.

Theoretically, when a star exceeds a multiple, it loses all its gravitational pull, causing gravity to continue to collapse and eventually form a "black hole".

To sum up, black holes all come from supernova explosions, and the above is mine, I hope it can help you.

Black holes are a phenomenon that occurs after a star is large enough to run out of fuel for a nuclear fusion reaction. Every black hole has a temperature, and the height is inversely proportional to the mass of the black hole, and the volume will shrink and **.

Black holes are formed by the gravitational collapse of stars with sufficient mass after they run out of fuel for the nuclear fusion reaction and die. Black holes exist because their gravitational field is very strong.

Black holes are a very mysterious celestial system in the universe, and human scientists have been studying black holes for a long time, but there has been no way to study them thoroughly.
