Light has no mass, so why is it swallowed by a black hole?

Because although light does not have a mass at rest (only theoretically, in fact, there should be, but infinitely close to and without, we cannot measure this mass yet), but it has a moving mass. There are two explanations for light being affected by gravity, the classical explanation and the general relativity explanation. What you say about gravity is related to mass is the classical explanation.

The theory of relativity explains that gravity causes space-time to bend, causing light to change its path.

Photons do not have a resting mass, and the deflection of photons caused by the gravitational pull of the so-called black hole has been clearly described in Einstein's general theory of relativity as the distortion of space-time caused by mass, and the photons themselves still propagate according to the shortest distance in space. Photons must have mass, are extremely tiny spheres, and when their density is extremely high, like a laser, it destroys everything. Black holes are celestial bodies from which even light cannot escape, so of course black holes attract light.

The essence of the problem is that the black hole bends space so much that the space within the Schwarzschild radius shrinks into a singularity, and the light enters the singularity after crossing the Schwarzschild radius, which is equivalent to the light being attracted into the singularity by the black hole.

If you look closely at the relationship between gravity and energy, you don't know if you find that the direction of energy movement is against the direction of gravity. For example, the heat on the earth is going upward. Since the black hole is a shrinking body in the universe, then the energy must be moving outward in the direction of the black hole's contraction.

Light waves are energy, so black holes don't absorb light waves. They are completely different directions of movement.

Personally, I think but don't necessarily tell you that light spreads through dark matter, matter cannot transmit light, matter can only reflect light. Gravity is related to the depth and breadth of consciousness. If the amount of information contained in a photon is high and the value of the information is high, it will certainly be very attractive.

Therefore, consciousness guides and determines the gravitational pull of all things in the universe. This is a strong proof and concrete guarantee for us to strengthen the learning of natural language systems and enhance the decisiveness and effectiveness of consciousness.

The main reason is that the gravitational pull of the black hole is so great that the light is distorted, which makes people feel this way, but it is not actually the so-called swallowing.

This is because when light passes through a black hole, there is no reflection of light, and when you can't see the light, you will naturally think that it is swallowed by the black hole.

Because the black hole is too big and too long to shine through, not to swallow it, but to light energy that can't reach the end, like a night flashlight, it can't shine far.

The main reason is that light has a strong energy, and this matter can interact with black holes.

It is common for light to be absorbed in the process of propagation!

Preface: A stationary photon has no mass, but a photon will fly forward after it appears, so a stationary photon does not exist. When photons move, they have momentum and energy, so photons in the universe have mass, and it is normal for photons with mass to be sucked into the black hole due to gravitational attraction.

The gravitational pull of the black hole is very large, and the space of the black hole is very distorted, because the mass of the black hole is too large, so it will cause the surrounding space to be distorted to an unimaginable degree, so as long as you get close to the black hole, any matter will be sucked in.

In the universe, black holes are a very terrible kind of celestial bodies, devouring any matter in the universe, although black holes are very terrifying, but black holes can not exist forever, because in the cosmic environment there will be positive ions and negative ions born, these particles will annihilate each other in a short time, if a pair of particles around the black hole one of the particles falls into the black hole, then the other particle will be annihilated, at this time it will be transformed from virtual particles to real particles.

In the process of transformation, the particles will also absorb the energy in the black hole, so the mass of the black hole will also be lost, and the black hole will slowly disappear over time. The reason why black holes can swallow any matter is also because the gravitational pull of the propelled force is very strong, and the density of any matter cannot be compared to that of black holes. Any moving object will have mass, and at the moment when the photon is generated, it has the speed of light, so it also has mass.

The space of a black hole is a distorted vortex, and there is no way for light to come out after it is inhaled, because the space is too distorted, and in the process of inhalation, the light will also be affected by the vortex, so it cannot be observed by humans. Because light travels in a straight line in space, but the mass of the black hole is very large, and the space distortion is relatively large, the light will be distorted along with the space, resulting in the phenomenon of being swallowed.

Because the mass of the black hole is very large, very large, and faster, it is all dark inside, and the light cannot be seen after entering, so it is equivalent to being swallowed by the black hole.

Black holes are the biggest secret of the universe, and black holes may exist beyond time and space. Because black holes have a strong ability to devour. Even light cannot penetrate a black hole.

Because light is a type of light that diverges. And black holes are a very massive color that can devour everything, including light.

To break through the constraints is to accelerate, as long as the speed is fast enough, you can break through the distortion of space and time of the massive celestial body, and get free, as for how fast to be free, this can be achieved through formulas, it is these formulas that make people discover that if the density of the celestial body is large enough, then it needs to be faster than the speed of light to break away from the celestial body, from which astronomers and physicists deduce the existence of black holes.

The escape speed required to escape from the planet. From left to right, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune. Since Pluto is no longer a planet of fortune, it is not on the gif, alas, even in the field of science, the title is important.

So, what exactly is going on between a black hole and gravitational waves, and why a black hole emits gravitational waves when it collides and sends them into orbit is a question that no one has ever asked. Since Einstein's general theory of relativity replaced Newton's law of gravitation with the distorted mass of space-time, this leads to a corollary, <>

That is, when the mass of the object's motion changes, then the curvature of space-time will constantly change, and when the space-time that was once curved behind the object's motion becomes straightened again, and the space-time that was once flat in front of the object becomes curved; This curvature of space-time is not confined to local areas, but spreads outward like ripples. These are known as gravitational waves. Gravitational waves are ripples in space-time and are caused by the movement of massive objects through space-time.

Therefore, black holes and gravitational waves are not contradictory, <>

When a black hole is set to move, it may disturb the surrounding space and time, considering that black holes are usually very massive, so their intertemporal and spatial interference is stronger, and the nature of gravitational waves is stronger, but why do the gravitational waves we detect usually arise from the merger of black holes or neutron stars? Because when they merge, they usually rotate around each other extremely quickly, which creates extremely powerful gravitational waves that can travel great distances to reach the Earth. When gravitational waves pass through a distant observer, the observer notices that space-time is distorted.

The distance between two free objects fluctuates rhythmically at the same frequency as gravitational waves.

However, in this process, the two free objects are not actually subjected to a force, and the absolute position of the coordinates does not really change, but their relative distances do, because the space-time coordinates themselves are also changing. The intensity of the gravitational wave at the observer is inversely proportional to its distance from the source. According to **, a spiraling approaching neutron binary star system will emit powerful gravitational waves due to its large mass and high acceleration.

But due to the large scale of astronomical distances, the impact of even the most violent gravitational waves, when they reach the Earth, has become extremely low, and the ripple effect is on the order of less than 10 21 meters, much like a distant wave, after a long enough distance, into a wavelet.

It is mainly because of the gravitational pull and the change in the situation in terms of nuclear fusion of matter, that it is absorbed by black holes.

Because black holes can distort space-time, and they also produce some gravitational waves. That's what happens.

First of all, it is because of the gravitational attraction and the change in the nuclear fusion of matter, so it is absorbed by the black hole.

This is because the gravitational pull of a black hole is relatively large, and the energy demand is also relatively large, plus the electromagnetic wave itself has a large amount of energy, and it will be attracted if you can't see it.

Because some massive stars distort the space around them, the direction of light propagation changes.

Although photons have no mass, photons belong to the nature of electromagnetic fields, and black holes can distort space-time and change the material motion of electron magnetic fields because of their extremely strong gravitational effect, and they can attract photons to black holes.

Because light belongs to matter and also belongs to energy, black holes absorb all matter and energy.

In fact, light is not without mass, in fact, light just has no static mass, but it has moving mass, so the black hole can absorb light, not so much that the black hole absorbs light, but that the black hole changes the direction of light.

Light is also composed of particles one by one, and it is also a kind of matter, so it is also within the scope of gravity. There is no way for light within the Schwarzschild radius of the black hole to escape. Because light has entered the event horizon of the black hole, the gravitational pull at this time has reached the speed of light.

It is not to absorb the light, but to attract the glowing object, so the light naturally rotates, such as sucking the glowing flashlight, so the light can not follow the rotation? If the light source is outside the black hole, how can its light suck and rotate? It's a fact that light can't be transferred, and it can't be stored.

The main reason is that space is distorted due to the strong gravitational pull of the black hole, and the space is not a flat structure, but the propagation path of light appears to be curved. In fact, light is deflected in the direction of large curvature, that is, the center of the black hole is deflected, and the more it is deflected, the greater the bend becomes, entering the black hole.

In physics, light always moves in a straight line in space-time, and black holes, as the most gravitational objects in the universe, severely bend space-time, and when 300,000 kilometers per second of light passes around the black hole, the propagation path also changes and is swallowed. When we often say that time is coordinated, there is an understanding of relative time, and the inherent time is the absolute value that is invariant according to the coordinate system expressed by the theory of relativity.

Regarding the difference in static mass and the nature of gravity, we can conduct a thought experiment, we know that the white light emitted by the sun is synthesized by electromagnetic waves of various frequencies, and the moving mass varies with the electromagnetic waves of frequency. The space in the event field of view is bent high due to its strong gravitational pull. An enclosed space is formed.

Because it is a closed three-week space, it is impossible to get out of this area as soon as you enter it, so the end of the event field of view looks like a black sphere.

According to the law of gravitation, we know that mass is required in order to produce the action of gravity between two objects, and light has no static mass. Therefore, as mentioned above, although the gravitational force of a black hole on light cannot be determined by the static mass of light, the gravitational force of a black hole can be corrected by using the dynamic mass of light as well as the law of gravitation. It should be noted here that although the mass of light is not involved in the whole correction process, the premise of using Newton's law of universal gravitation is that only the light has mass, that is, the light has mass, is considered to be corrected.

Einstein believed that as long as there is a mass object, it will cause the curvature of space-time, and the curvature of space-time represents the curved scale of space-time.

The gravitational force described by the theory of relativity is essentially the curvature of space-time, which can be understood as a black hole is a nadir in space-time, and all matter flows to this low place like water, and the speed of escape is fast enough to escape, but the escape speed within the event horizon is greater than the speed of light.

Light has no mass, so how do black holes absorb light?

The black hole does not attract light sources, but because of the large mass of the black hole, the time around it is significantly bent, and the light is distributed in the linear shape of time, and the light is distributed linearly in the gravitational field of the black hole, but the time is uneven. According to general quantum theory, the essence of force is not the ambiguous relationship definition of Newtonian mechanics - the natural force of quality in most objects, but the distortion of time and space. Every chemical substance, regardless of quality, is also affected by space-time distortions, and in the space around the black hole, the light source will bend more and more than parallel lines, in fact, light walks in a straight line.

This kind of phenomenon is not unfamiliar with the main expression of attraction, and black holes can be said to be "deeply attracted to light sources".

When analyzing this problem, we can also treat light as a particle, if we can, the quality of this light particle is not nothing, but it is a light quantum, and there is no static quality, but we can have the quality of quantum theory because we know that it never stops moving. According to Einstein's equation of quality, matter and energy are essentially the same, matter and energy can be transformed into each other, if you know the energy of photons, you can know the quality of light quanta, but light quantum (quantum) energy can be calculated using the frequency of light.

From the standpoint of quantum theory and Newtonian mechanics, light quanta can be subjected to force, and black holes can attract light quanta. Why are light quanta distributed linearly in the critical plane diagram of a black hole? This situation is actually quite easy to understand, suppose a person on the earth walks along the earth's equator for a week, just follow the parallel line, for the person on the earth, he will definitely return to his footing, but if the cosmic space describes the path of the person, you are not in this situation, but in the curve.

Similarly, even within the gravitational field of a black hole, light that cannot be conveyed by parallel lines looks like it is conveyed by parallel lines, which is a small story for the light itself.

According to Einstein's quantum theory, the reason for the formation of force is generally the bending of quality objects in the vicinity of space-time, the bending of objects with large masses, and the actual effect of time is getting higher and higher The sunlight is okay (it has a certain effect on Quinrobert, but it is generally not observable, only in the total solar eclipse, such an effect is that in 1919, Father Eddington observed the total solar eclipse according to the reflection of sunlight, which verified the accuracy of the general quantum theory in the vicinity, because the time is very bent, Therefore, it can be seen that there is a huge change in the method of light mobility around the black hole.
