According to the black hole principle, light cannot escape from a black hole because the black hole

These rays are not actually emitted by the black hole itself, but by matter that is about to fall into the black hole outside the black hole's event horizon.

We can find the existence of black holes, because experts use the characteristics of black holes to understand the existence of black holes according to the interference of surrounding stars, that is, according to the strong X-ray source in the black hole region**. Although the black hole itself cannot emit all light sources, it still has a great attraction for surrounding objects and stars. When the surrounding material is attracted by its strong attraction and slowly falls towards the black hole, it emits powerful X-rays, producing an X-ray source in the sky.

Based on the search and observation of the X-ray source, one can look for the footprint of the black hole. The discoverer of the black hole is Meti Schwarzschild, a French scientist and astronomer, although Schwarzschild is the proposer of the basic theory of black holes, but what really makes black holes famous or the world-famous scientific theory of black holes created by Stephen Hawking, it is also Stephen Hawking who makes black holes more and more well-known.

As Stephen Hawking often said, he felt that black holes could be turned on, and the data they swallowed could be released in another way. Everyone's brain terminates logical thinking, and when the situation is to subside, the body's nervous system is also deep in a state of stagnation, and the storage memory of people's brain consciousness during the Qingming Festival is the obvious ** or belief belief power, and it is also the last of the energy power of consciousness, and the consciousness will join the dark valley, gradually moving away from it, and slowly falling. The whole process of consciousness training is the inner vision that is correctly guided by the subconscious, and the subconscious consciousness of the indoor space of the Qingming Festival.

Black holes are supposed to be an aggravation of the rotation of primordial matter in the space lanes, resulting in a reaction like a sandstorm on Earth. The energy and matter elements only accelerate endlessly in the stress-free black route, and the crushing energy that attracts the matter is released by the radiation increase, which should be related to the dark matterBut inside the black hole is in a hurry. The energy of the high-temperature grease to participate in the chemical reaction should be dark energy, and antimatter energy should also be released.

This is due to the fact that human beings have invented a lot of scientific research equipment and also invented a lot of space equipment, so it is through these space equipment that black holes have been discovered.

By observing the planets around us, these needs are slowly sucked in, and then the existence of black holes is learned.

Because the weather around the black hole behaves abnormally, it is through this feature that humans discovered black holes.

Summary. According to existing astronomical theories, a black hole of any mass has a gravitational field sufficient to attract and prevent light from escaping. This means that even very small black holes can become "traps" for light, making it impossible to escape.

And, according to the black hole's concept of an "event horizon", no object at a certain distance from the black hole's surface can escape the black hole's gravitational pull, including light. The event horizon distance depends on the mass of the black hole, and the larger the black hole, the greater the event horizon distance and the wider the engulfing range. Therefore, according to the current scientific theories, a black hole of any mass can cause light to be unable to escape <>

To put it bluntly: a black hole is an infinite mass and dense celestial body, with a very strong gravitational pull that makes it impossible for light to escape. Is this statement correct?

Dear, this statement is correct, oh <>

Aren't there many types of black holes? And not all black holes are infinitely dense in mass.

There are three types of black holes known to exist in the universe: primordial black holes, stellar black holes, and supermassive black holes.

Not all black hole mass densities are infinite. The mass density of a black hole is the ratio of the mass of the black hole to its volume, so the larger the mass and the smaller the volume, the greater the mass density of the black hole. There is a theoretical type of black hole called a "miniature black hole", which has a very small mass but a very high density.

And ordinary stellar-mass black holes, although also very dense, are not infinite. The mass density of a black hole depends on its mass and volume, and different types of black holes will have different mass densities.

In conclusion, the gravitational pull of a black hole is indeed so strong that light cannot escape. However, its mass density is not truly infinite, but very large.

How do you explain this? Could it be a special case?

According to current theories of physics, the lower limit of the mass of a black hole is the mass of a star, that is, about the mass of the sun.

The mass of a black hole refers to the total mass of the matter it contains, usually measured in terms of the mass of the sun.

In the process of studying the universe, scientists discovered the special phenomenon of black holes, and we can understand that the mass in black holes is very large, and can swallow almost all matter and light.

Scientists discover black holes by observing and calculating the trajectories of celestial bodies, rather than observing them directly.

Scientists judge black holes based on the motion around the stars, and black holes are very dangerous.

Large black holes can expand continuously, while small black holes evaporate. （）

a.It is pure and true.

b.Mistake. Correct answer Liang Bu: Do zatan a

I think black holes are formed by some quanta, so I think inside a black hole is a very dark space, and it's a very scary space, and it's also an attractive space.

There are two people who, based on Newtonian mechanics and the theory of relativity, have proposed that light cannot escape from black holes. One was proposed by the 18th-century British scientist John Michel and proved by the French mathematician Laplace. After the theory of relativity was proposed, John Wheeler theoretically predicted the existence of black holes by proving that once light enters the event horizon, it cannot escape from the theory of relativity.

So, it was John Wheeler who proved that light can't escape a black hole.

Since humans have not yet been able to fly out of the Earth-Moon system, no one has ever been to a black hole, and even the earliest human probe has not yet flown out of the solar system. Until now, all the properties of black holes have been known through theoretical calculations and astronomical observations.

There is a phenomenon that can prove that the gravitational pull of black holes is very large, that is, the accretion of black holes, when one of the close binary stars is a black hole, the black hole will attract the material of the companion star, and the attracted material will emit high-energy X-rays before falling into the black hole, and people can prove this process according to X-ray observations.

lz first of all, I will explain to you the escape velocity, I don't know if you understand that the escape velocity is the speed required to leave a celestial body.

That is, a certain velocity must be reached to completely escape the beam of the object, and calculations show that the escape speed of a black hole is the speed of light.

Albert Einstein told us that no object can exceed the speed of light.

So even light can't escape a black hole.

Second question.

A black hole is a celestial body formed by the collapse of a massive star after its death.

As the volume decreases, the density inevitably increases.

Whereas, density and gravitational force are inversely proportional.

The higher the density, the greater the gravitational pull.

So black holes have a lot of attraction.

100% original, please do not plagiarize].

1. No one can directly prove that light cannot escape black holes, this is only through theoretical calculations and some circumstantial evidence, because human beings have not yet been able to produce objects with black hole-like energy.

2. No one has ever been. At present, the farthest place that humans go is the moon, and if there is a black hole near the moon, then the solar system is over.

3. To prove that black holes have great attraction, first of all, there is a theory based on Einstein's theory of relativity, which states that space is not flat, if the gravitational force is large enough, it can even distort space, and light propagates in space, if space is distorted, light is also distorted, this is proved at the time of the eclipse, if the mass of the object is large enough, the gravitational force generated can distort space into a closed ring, a. Any matter outside the critical point of the closed ring includes light, will be ejected by gravitational distortion and leave the original trajectory. b Matter that happens to be at the critical point of the closed ring will continue to orbit the black hole, and will not appear or be sucked in. c Matter within the critical point of the closed ring will fall into the black hole in a spiral trajectory and eventually attach to the black hole, becoming energy or mass is unknown, because all the current laws of physics in the black hole no longer apply.

Finally, the reason why black holes are well-known is because of Hawking's blessing, and the book "A Brief History of Time - From the Big ** of the Universe to Black Holes" (written in 1988) is Hawking's masterpiece. The author's imagination is rich, the ideas are wonderful, the language is beautiful, and the words are exquisite, which is even more amazing"world"In addition, the future changes are so magical and wonderful. The book has a cumulative circulation of 25 million copies, has been translated into nearly 40 languages, and has sparked countless people's yearning for space.

A black hole is a special celestial body. There are many theories about its formation, and most of the current theories are stellar collapses. Because it was formed by the collapse of a massive gravity well at the time of aging of a star with a mass of 30 suns, it could not support itself.

Due to its own collapse, its own particles squeeze the gravity well around an infinitesimal singularity with a huge density that cannot be calculated. Anyway, it first appeared in Albert. No one has been to Einstein's "Guangyi Theory of Relativity".

Einstein observed that the perihelion of Mercury's orbit around the Sun is constantly spiraling (Mercury is closer to the Sun and is more obviously affected by it), and there is a large error with Newton's classical mechanics, so he thinks that massive objects can distort space, and then concludes that the starlight passing by the Sun is deflected (the Sun is a massive celestial body, and it can distort space-time like black holes) Hawking also has great achievements in this area.

1.That black hole? Is it the reincarnation black hole of the Locke Kingdom? Someone must have gone to the reincarnation black hole of the Rock Kingdom! I've even been there.

2.The guardian of the ghost badge in the reincarnation black hole of the Rock Kingdom is Lucia, her elves are very powerful, and her elves are all level 70-75.

This is called theoretical physics, where experiments are difficult to verify, through mathematical calculations, hypotheses and reasoning.

According to the current theory, the propagation speed of force cannot be measured, and we generally still think that force acts instantaneously, and we generally use large and small units in the unit of force, and there is no such thing as fast or slow.

So, it doesn't make sense for you to think that gravity is faster than light, it's like a rocket flies fast, not because its propulsion force is faster than a rocket, according to Newtonian mechanics, as long as there is an external force, the physical state of motion will change, not that the external force is faster than the object is in motion.

Moreover, movement is relative. So what you said is not valid at all.

And we know that the gravitational force exists between any object with mass, then, again, under the action of external force, the motion state of the object must change, then, the mass of the photon in the motion state is not 0, so he will naturally change the motion state under the action of the external force (here the guiding force).

However, when the gravitational force is small, it cannot be measured with our current measuring instruments, but when the gravitational force is large, such as when the light passes through the sun, the light will bend because the sun's gravitational pull on the photons is large, which has been confirmed by observations.

When the gravitational force increases to a certain extent, the light rays will not only bend, but even reverse, which is a black hole.

Of course, the above is not correct to explain the problem in terms of classical mechanics.

The real situation is that gravity distorts three-dimensional space, which is why the light is bent. This is complicated and difficult to understand, so I won't explain it.

The average person just thinks that the gravitational pull of a black hole is so strong that it ......But if you can think of the speed of gravity that ordinary people can't think of from here, I want to applaud you!

It is also possible to imagine a gravitational field, like a net, waiting for the light to cast itself into the net.

Unfortunately, both of these questions are unanswered by astrophysics (or other physics), so while observations show that light bends around the black hole, we don't know exactly what it means.

If interested, you can stay tuned to this issue.

Hello, light cannot escape the gravitational pull of a black hole because the gravitational pull of a black hole is so great that light cannot escape.

A black hole is a massive and gravitational object. There is indeed a space-time distortion around the black hole, but it is not caused by gravity, this space-time distortion is due to the huge mass and relatively small volume of the black hole. We can think of space-time as a sponge, and the smaller the volume and the more massive the object, the deeper the depression.

When a glass ball passes through the depression, the shallower depression will cause the glass ball to change the direction of motion, but will not cause the glass ball to fall towards the center of the depression; When the glass ball passes through a deep depression and the slope is so steep that the glass ball cannot leave the depression at a very fast speed, then the glass ball will fall in a spiral pattern towards the center of the depression. The space-time depression created by the black hole around it is like a sponge, and the huge mass and small size of the black hole make the depression very, very deep. As light passes through its gravitational range, it moves toward the center of the depression due to the unusually deep space-time depression.
