How to understand that a black hole is a particle?

When the shape and size of the object itself are not taken into account, and the mass is regarded as concentrated in one point, the object is regarded as a "particle". It is a scientifically abstracted concept in mechanics and an ideal model.

Objects that can be seen as particles are often not very small, so they should not be confused with microscopic particles such as electrons. If the problem does not involve rotation or if the size of the object is very small compared to the distance involved in the problem, the actual object can be abstracted as a particle. Therefore, whether an object is regarded as a particle or not depends entirely on the nature of the problem under study.

Since black holes retain only three physical quantities: mass, charge, and angular momentum, our general research questions default to particles. The Pauli incompatibility principle supports the existence of neutron stars and unproven quark stars, but it fails in black holes.

It is important to note that black holes do not disable quantum mechanics and relativity as described on the second floor. As long as the principle of invariance of the speed of light exists, the special theory of relativity is constant. The general theory of relativity is only destroyed by space debris or quantum mechanics at the singularity or microscopic point, and the black hole itself is a product of the general theory of relativity.

And I haven't heard of a theory that can invalidate quantum mechanics, even if it's a big singularity, it's dominated by quantum fluctuations.

Addendum: The radius of a black hole is the Schwarzschild radius, but the point depends only on the problem being studied. For example, when studying the attraction of black holes in the nucleus of galaxies to stars in the entire galaxy, black holes can of course be regarded as particles.

But if you are studying the information of the event horizon of a black hole, of course, the black hole cannot be regarded as a particle. But the volume of a black hole is related to the Schwarzschild radius. A black hole is difficult to understand as a sphere because the space around it is heavily distorted.

But its increase in volume is in accordance with the basic laws of geometry. It's just that we generally only use mass and event horizon area to measure the size of a black hole, not volume.

Black holes invalidate both relativity and quantum mechanics, and how can Pauli not be able to do so.

Wrong, the repulsive force of Pauli's principle of incompatibility is no longer sufficient to displace the gravitational pull of thirty suns.

Black holes are insignificant to the universe.

The quantum ocean is here again, idol.

Who said it was a particle? The theoretical radius can be calculated, and college physics has it all said.

Why haven't I heard that a black hole is a particle? Textbooks say it has a certain size! The contest also provides the radius of a black hole! Dizzy, am I really lonely?

It's impossible, theoretically, there is a qualitative point, but will it really appear in practice?

Black holes are formed by the gravitational collapse of a massive enough star after the fuel for the fusion reaction runs out.

A particle is a point that has mass but no volume or shape.

Conceptually, a black hole is not a particle.

Particles are relative, regardless of the size of the object, and black holes can be counted as particles relative to other objects.

If you calculate the distance between stars or gravitational force, etc., it can be regarded as a particle. The influence of computational power on the trajectory of short-range photons cannot be regarded as particles. However, in general, the computational black holes involved in high school and college physics are regarded as particles.

Particle: When the shape and size of the object can be ignored in the problem under study, the object is regarded as a geometric point with mass, and such a research object is called a particle in mechanics.

Singularity: The point at which space-time begins or ends.

So the mass ≠ the singularity.

But a black hole can be thought of as a mass (a black hole with a singularity at its center).

Black hole formation: When a star more than 30 times more massive than our sun runs out of fuel, it produces a supernova explosion (supernova explosion), and the material left behind after the explosion is a black hole.

Black holes: When an object is extremely massive and has a positive body, it will severely distort space-time so that even light cannot escape from its surface.

Upstairs said that, yes.

A black hole is formed because it rotates so fast that even light cannot be reflected.

Black holes eventually lead to the formation of singularities, but not inevitably. The formation of a singularity, the breakage of space, leads to the emergence of antispace, and at the same time detonates many black holes.

At the same time, white holes and anti-space also exist, but anti-space and antimatter exist for a very short time, and white holes existed when primitive galaxies were formed, so they are not long. None have been observed at this time.

Black holes appear to be constantly devouring objects, but inside the black hole are actually constantly compressing time and space, which can be understood as a black hole that converts matter into energy to compress time and space.

When a black hole swallows an object to a certain amount of energy, or because of a collision between black holes, time disappears at a point (the beginning of time equals the end), and space is infinitely smaller. This is where the singularity is formed.

The formation of the singularity, the disappearance of the space in the region, the chain causes the disappearance of other related spaces, this break is the emergence of anti-space, like lightning in the night, only the break in the universe is faster than the speed of light, the break can be said to occur synchronously, the speed is infinite, this is the singularity of the **.

The rupture of space disappears, the ** of the singularity, the dense anti-space disappears like lightning, and countless lightning terminals continue to release energy, impacting space and beginning to form white holes, and the released energy collides at the speed of light and erupts matter to form new galaxies, which is why galaxies are disk-shaped.

The white hole releases matter to form galaxies, due to the speed of light barrier in space, it is impossible to run in a straight line, and the white hole flips over the core of the galaxy formed at the end, which is also the reason why the core of the galaxy is spherical, because the edge of the galaxy is the white hole that erupts first to release the celestial body, so the age of the galaxy edge celestial body is older.

The latest research shows that the center of a black hole is not a singularity, and that the matter sucked in it goes to the future.

Because the center of the black hole has the transformation of matter, the matter will be torn apart in an instant to become dark matter, so its center is a singularity.

The main reason why a black hole needs a special light body to form this structure is that it is normal for this singularity to form at a certain point.

Because black holes are so dense that ordinary matter simply cannot reach such densities, the center of a black hole is not matter but a singularity.

Stars with a mass about the same mass as the sun can crush atoms and eventually become white dwarfs, stars with about 2 solar masses can crush protons and electrons together to become neutron stars, stars with more than 3 solar masses can crush neutrons into quarks and thus become black holes, black holes with more mass can crush quarks into subquarks, black holes with greater mass can crush subquarks into more basic particles, and the most massive black holes may have the most basic particles in them, but how can it be said that once a black hole is formed, Inevitably, the matter inside will inevitably be compressed into a single point? Laplace once predicted that a celestial body with a diameter of 250 times the sun and a density as the earth would have a gravitational force sufficient to capture the light it emits and become a dark object, which is now confirmed by observation (although black holes are generally invisible, a massive black hole will see an obvious black hole in the galaxy when it passes through the galaxy), But who can prove that the matter inside a black hole must be compressed into a single point? Not only is there no evidence, but the most important thing is that the compressibility of matter is finite, how can it be infinitely compressed into a point?

The birth of a black hole.

Like white dwarfs and neutron stars, black holes are likely to evolve from stars.

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 (refer to the astronomical dictionary) 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' speculation) matter will march inexorably towards the central point, until it becomes a "point" with zero volume and infinite density. And when its radius shrinks to a certain point (Schwarzschild radius), as we described above, the huge gravitational pull makes it impossible for even light to shoot outward, thus cutting off all contact between the star and the outside world - and the "black hole" is born.

Einstein's theory: there is a conservation of energy in all things in the universe, but it is unevenly distributed, and the planets and galaxies are large and small, the gravitational attraction of the large ones is strong, and the gravitational attraction of the small ones is weak, resulting in the creation of black holes!

First of all, it is necessary to understand that the so-called black hole is a celestial body with extremely strong gravitational attraction formed by the collapse of the star due to its own gravity at the end of its life.

For example, it's like putting a super vacuum cleaner under the roof of a house. If the suction power of the vacuum cleaner is greater than the capacity of the house, then the house will collapse. This vacuum cleaner is the inner core of the star, where gravity is born.

The roof of the house is the façade of the star. Once the house collapses, the vacuum cleaner will continue to work. And the suction will become stronger and stronger.

Even the vacuum cleaners in some houses will suck the light in. So when we look at such a vacuum cleaner, there is a lack of light. So we can only observe a black space.

It's what we call a black hole for short. Therefore, black holes are currently not directly observable. However, the existence of a black hole can be proved or determined by indirect means.

For example, the edge of a black hole sometimes shoots a large number of X-rays outward. It's like a vacuum cleaner that collides with each other when it sucks things into the house.

I am a shallow learner, if there are inaccuracies in the analogy, please bear with me

In fact, black holes are very simple.

It is because a star is too massive to resist its own gravity after emitting light, resulting in continuous compression, because the gravitational force becomes greater after becoming smaller (gravitational force is inversely proportional to the square of the distance) and finally the mass of all planets is concentrated at one point. The mass of this point is extremely large, and the body is very small.

And this point is massive and small, so the gravitational pull is so great that even light can be absorbed, so we can't see this point. Hence the name black hole. Also called singularity (strange odd, hehe).

Although it is not visible, the gravitational anomaly can be detected by the bending of the surrounding light.

There is a gravitational force. When the gravitational pull is so strong that it can't even get out of the speed of light, it becomes a black hole.
