Is light an object? Why does the gravitational pull of a black hole capture light?

The gravitational field of a star changes the path of light so that it would have been different from what it would have been without a star. A light cone is an orbit that represents the space-time propagation of light rays after emitting from its tip. The light cone is slightly deflected inward near the star's surface, and this deflection can be seen by observing the light from distant stars during a solar eclipse.

As the star shrinks, the gravitational field on its surface becomes stronger, and the light is deflected inward more, making it more difficult for the light to escape from the star. To an observer from a distance, the light becomes dimmer and redder. Finally, when the star shrinks to a critical radius, the gravitational field on the surface becomes so strong that the light cone is deflected inward so much that the light can no longer escape.

According to the theory of relativity, nothing will go faster than light. In this way, if the light cannot escape, everything else will not be able to escape, and will be pulled back by gravity. That is, there is a collection of events or a space of time – a region from which it is impossible for light or anything to escape to reach a distant observer, such a region is called a black hole.

I think that light is not an object but must be emitted by a luminous object, and the gravitational pull of the black hole sucks the luminous object in, and finally the luminous object collapses and the light disappears, I personally think.

Light is an object! There's the Compton Effect to bear witness! Light has wave-particle duality!

A black hole is depleted of internal energy, and it absorbs all light, because light is energy radiation! Just like light as we know it is absorbed by a black substance!

The photon maintains a fixed speed and has kinetic energy, so it has to be affected by gravity, and the gravitational force of a black hole is very large, and the speed of light cannot reach a speed that can get rid of the gravitational force of a black hole, so it will be attracted by the black hole.

The black hole does not attract light, but because the mass of the black hail hole is very large, as long as the surrounding space-time is bent, and the light propagates in a straight line, so the source will give us a phenomenon that light is attracted to the black hole.

The black hole does not attract light, but rather the body of the light source that is emitting light. So of course, the light goes around with the balance. For example, I attracted a glowing liquid flashlight.

The main reason is that black holes contain a lot of matter, and these materials will also reflect light, so there will be a certain element of light.

I have time to read my article "Carrying Letters and Leaking Truth and Falsehood in the Universe.""Black holes"Why do you say that?"Gravitational waves"And doesn't exist? 》…A bad argument"A jasper orchid chasing stars in Lingjing Lake"Can.

Gravitational attraction has an effect on light. For example, gravitational lensing, gravitational redshift. When light passes near a massive celestial body, its gravitational pull (or its entry into the curved space near the object) causes the course to be deflected, known as the "geodesic effect".

Black holes have a huge gravitational field, and when the light reaches the inside of the black hole, the gravity increases by a billion times per second. It was as if the light had been swallowed up.

Light can be affected by gravity, which is theoretically possible, and in reality the gravitational pull of the sun can be used to observe the distance between the Earth and other planets. It can be said that if gravity cannot affect light. Then our solar system model will not be able to be built.

The theory that light is affected by gravity is derived from Einstein's special theory of relativity, in which the concept of gravity is removed and replaced with a simulated displacement. For example, if you are in an elevator, when the earth's gravity decreases, you feel the same as when the elevator goes down, and when the gravitational force goes up, it is the same as when the elevator goes up. The same is true for light, the light enters the elevator from point A at elevation, and the elevator rises after the gravitational force rises.

The elevator rises but the light shortage will not move, so the elevation of the light-receiving point should be the overall rise of the elevator's movement, so the surface height of the light-receiving point is the light-entering surface height a displacement b. If you add an observer to the elevator at this point, you will see that the light falls in an arc. As mentioned earlier, this displacement is a simulated displacement, but in fact, the elevator is not moving, so gravity will cause the light to bend towards the center of the position.

Some people say that gravity is essentially a distortion of space, and this view is also true in a certain sense.

And light can indeed be distorted by gravity.

The direction of the evolution of celestial bodies is the gradual transition from low density to high density. They are stars, white dwarfs, neutron stars, and black holes.

When an astrosphere evolves into a black hole, its density is very high. All of the elementary particles (matter) that are closed systems are crushed and reduced to the smallest indivisible particle, the quantum. Therefore, black holes, unlike other celestial bodies, are essentially a huge ball of energy, i.e., a closed system of energy, and therefore have an extremely high energy density.

According to the organic quantum cosmology, the ground state quantum constitutes space, the excited quantum becomes photons, the closed system composed of high-energy particles is all kinds of elementary particles, and the higher-level closed system formed by various elementary particles is atoms, molecules and macroscopic matter in turn.

Therefore, the motion of any object will be bound by quantum space, and their external energy has two different forms, namely kinetic energy about itself and potential energy relative to space.

Since the eigenparameter of the photon is Planck's constant h, the dimension of which is the angular momentum of the particle, the photon is also a particle, which also has a minimum mass and a fixed radius.

Therefore, the energy of the photon, like other objects, also has two different forms of existence, namely kinetic energy with respect to itself and potential energy with respect to space.

It's just that because the mass of the photon is so small, that the energy of the photon, mainly its change relative to the potential energy of space, is manifested as the speed of light has an approximate invariance with respect to both space and energy.

Therefore, because the energy density of black holes is very large, that is, the quantum space is extremely asymmetrical, when photons escape from the black hole, they are bound by quantum space. Moreover, the higher the energy of the photon, the greater the constraint, so that before the photon leaves the black hole, it exhausts the excitation energy it has acquired, metamorphoses into a ground state quantum, and thus loses the direction of motion.

As a result, photons that have lost their energy will be dragged into the black hole by the asymmetric quantum space, that is, they will be driven into the black hole due to the asymmetric collision of the space quantum.

From this, the photon regains its energy and tries to escape the black hole again. This cycle is the mode in which the photons operate inside the black hole. That's why photons can't escape from a black hole.

In conclusion, the energy of a photon is mainly the potential energy relative to space, and the magnitude of its potential energy is directly proportional to being bound by space. As a result, due to the excessive density of the black hole, the quantum space is extremely asymmetrical, so that the photon transfers energy to the quantum space in the process of leaving the black hole, thus losing the ability to leave the black hole.

The most rigorous language to talk about black holes is space. If you look at a black hole in the language of space, the light is not absorbed by the black hole, but the light itself does not move outward. In addition, black holes can also distort space-time.

Rays that move in distorted space-time will still follow the geodesic motion. The geodesic line in the event horizon of a black hole does not intersect with the outside, and there is no way for light to escape from the black hole. The above is the reason why light has no attraction without mass, and how black holes are absorbed by black holes.

Photons also have mass, but the mass is very small, so black holes can also attract photons into it.

Because the gravitational pull of a black hole is so strong that it can cause spatial distortion and change the path of light propagation, it can attract light.

Although it has no mass, it is also a substance, which can be sucked away through some processes, but we humans cannot do it now.

It is inaccurate to say that light has no quality. Light is not without quality. It just doesn't have a static mass.

Any object with a resting mass will produce an inertial mass during motion, and the inertial mass will bend and correspond to the gravitational mass. As the velocity of motion increases, the inertial burial mass of the object increases greatly. According to the mass-energy equation, when the speed of motion is close to the speed of light, the inertial mass will approach infinity, and infinite energy is required for continuous acceleration.

There is no infinite amount of energy in the universe, so it is impossible to accelerate a stationary mass object to the speed of light. Therefore, light, a matter with no rest mass, represents the fastest movement in the universe.

Because the gravitational pull of a black hole is so strong, even if anything as light as a feather can be swept up by its powerful attraction, without any power to parry.

Because black holes can absorb all matter, they can be absorbed without mass.

It is not accurate enough to say that the light crack balance has no mass, the light is not without mass, it is just that the stool source beam has no rest mass and any object with rest mass will produce inertial mass in the process of motion, and the inertial mass is equivalent to the gravitational mass, with the increase of the speed of motion, the inertial mass of the object will increase significantly, according to the mass-energy equation, when the speed of motion is close to the speed of light, the inertial mass also tends to infinity, and it requires infinite energy to continue to accelerate, However, there is no infinite amount of energy in the universe, so it is impossible to accelerate an object with a resting mass to the speed of light, so light, a matter without a resting mass, represents the fastest movement in the universe.

The picture above is a two-dimensional model of a black hole, and the three-dimensional one depends on imagination, hehe.

First of all, we must know how the black hole "sucks" light, according to the general theory of relativity, gravity will bend space-time, when the mass of the star reaches a certain critical point, or when the life ends (when the internal energy cannot resist the gravitational force), it will collapse into a black hole, the mass of the black hole is large enough, so the space-time bend is the largest enough, so big that it is like tearing a hole in space-time, if you are two-dimensional, you can see the above picture, anything that flies into this hole is like flying into a hole. For example, the Sun is a star that does not collapse, and because of its relatively small mass, it has a smaller curvature of space-time, much like if there is a small basin on the plains. And the black hole is like digging a bottomless pit (it really is).

And when light is straight (light propagation is always straight), when it encounters a curved space-time bend, it will inevitably "fall into this bottomless pit" and cannot get out, which is the first.

Second, according to the general theory of relativity, Einstein's relativity equation, gravity is a kind of wave, that is, there is the existence of gravitational waves, just like the electromagnetic field propagates electromagnetic waves, gravity also propagates by gravitational fields, but, so far, there is no experiment to prove the existence of gravitational waves. A giant collider needs to be set up in the vast expanse of space), but at present, the European Large Hadron Collider is also conducting experiments in this area.

The relationship between gravity and matter seems to be self-explanatory, but in fact it involves fundamental problems in physics, and it is not clear what the relationship between the two is. But theoretically there have been explorations, such as the Standard Model has been proposed as a God particle, but so far, there has been no experiment to find the particle, if it can really be done, at least we can know the mass of **, so that the problem of gravity may also be naturally introduced.

I hope you like physics and I hope you are satisfied.

Classical physics believes that gravity is a force that is planted at a distance, which is not true today, and general relativity holds that gravity is actually a mechanical illusion manifested by the change of the structure of space caused by mass, and it is not true to say that gravity is a force.

Because of the change in the structure of space, light is not a straight line when it travels in distorted space.

Because of the extreme density of a black hole, the space around it is extremely distorted, and the light travels and bends more in such space, so that it is possible to bend into the black hole.

It is right to say that gravity is a wave, because the propagation of gravity takes time, note: the concept of wave here is not the concept of classical waves, in general, the concept of gravitational wave is only used to discuss the propagation behavior of gravity at a certain time, not to discuss a continuous propagation process, we use the concept of gravitational field more when discussing the process, here it should be noted that the concept of wave and field is unified and inseparable, that is, the concept of wave must produce the concept of field. For example, a supernova erupts, its gravitational waves have to travel to the earth through a certain amount of time, but can also spread to Mars, Venus, so that we get the concept of gravitational field through gravitational waves, the concept of gravitational waves is proposed by modern physics, because classical physics believes that the propagation of gravity does not require time, which is also a reason why Newton's theory is wrong, and the special theory of relativity has given a conclusion through rigorous calculations: the propagation speed of gravity is equal to the speed of light.

In the Standard Model, it is the Higgs son that transmits gravity, which is a relatively avant-garde theory, but many scientists are optimistic.

They are justified in their optimism about this so-called Higgs, due to their belief in the symmetry and integrity of the universe.

The rest of the Standard Model particles have been found, but this Higgs seed has not been found, which is doubtful.
