Theoretically, the gravitational pull of any celestial body can bend light, but the degree of bending is different, taking our sun as an example, during a total solar eclipse, you will find that the position of the stars near the sun has changed, and the focus of the sun's gravitational lens is about 1000 astronomical units (light years) from the sun.
In the general theory of relativity, it is believed that the essence of gravity is the curvature of space, but in a weak gravitational field, the phenomenon of gravity can be approximated by the law of universal gravitation, and Einstein originally predicted the angle of deflection of light rays as they pass near the sun.
In 1915, the British scientist Eddington successfully measured the deflection angle of the light of distant stars when it passed the sun with the help of a rare total solar eclipse, and the results were basically consistent with the prediction of relativity, but far from the prediction of Newtonian mechanics, and this result became an important experiment to verify the general theory of relativity.
The mass of the sun is as high as 2*10 30kg, and the escape velocity is the earth, and the light deflection caused by its gravity is very weak, so the light deflection caused by the earth's gravity will be even weaker.
According to Einstein's prediction, space-time near massive celestial bodies will undergo large distortion, causing light rays passing near the celestial bodies to be bent, and if the observer is in a straight line of "light source-celestial body", then the observer may see one or more light source images, a phenomenon called gravitational lensing.
Gravitational lensing was first observed in 1979, and now microgravitational lensing has played an important role in astronomical observations, such as:
In 2008, scientists used microgravitational lensing to detect that the OGLE-06-109L star system, 5,000 light-years away from Earth, has two planets, with the masses of the planets being one and one Jupiter, which is simply impossible to achieve with traditional observation methods.
For example, in the image above, the NGC 7250 galaxy in the constellation Scorpio Tiger, there is a very bright star in the galaxy, which is actually a supernova, 45 million light-years away from Earth, and scientists have observed such a clear image with the help of gravitational lensing, and the observation distance is 100 times closer than the actual distance.
For the sun, the gravitational lensing effect can also be formed theoretically, and the focal length corresponding to the sun's gravitational lens is about 1,000 astronomical units, that is, 150 billion kilometers.

To bend light, the force of a black hole is required to achieve this effect, and it is very difficult to achieve.
-
As long as there is gravity, light can bend. The difference is only that the gravitational pull is greater, and the degree to which the light bends is greater, and vice versa.
-
This kind of gravitational force is quite large, because this kind of gravitational force can bend such a powerful substance as light, what a kind of skill, it is really good.
-
At least it should be greater than the energy of the universe.

When gravity is extreme, in other words, gravity can no longer be increasedThe indoor space will also be distorted to the limit value, and when the light is distorted in the area where the limit value is reached, it will not be able to get out, which is the strong gravitational pull of the hunger can not only distort the light, but the gravitational force of the limit value will continue to make the light entangle the light in the extremely distorted indoor space. The strength of this gravitational pull is really unimaginable, and people are amazed. Don't see it clearly, it's so strange to look at the universe!
Letting light bend is not gravity, it's atmospheric refraction. Massive stars are surrounded by deep atmospheres. Gases around the Earth at 1 atmosphere have a significant refractive effect on light.
The stars blink because the atmosphere is unstable and refracted. A mirage** is the refraction of the atmosphere on Earth. Looking at distant objects from the campfire, you can see the distortion and trembling.
A fully transparent balloon filled with carbon dioxide can be used as a gas bifocal lens. All of them show the refractive effect of gases of different relative densities on light. Sunlight has a great gravitational pull, and beyond the fireball is a deep atmosphere that stretches all the way to Pluto.
Produces a very large gas bifocal lens. When light passes around the sun, it is refracted by gas, and it is said that the gravitational pull of sunlight bends the light, which is the wind of ignorant biologists. Not only could he not prove the general theory of relativity, but Eddington proved for the first time that the general theory of relativity was a muse.
There is a consensus among everyone. Astronomical observations confirmed Newton's basic theory that gravity bends light, but he did not remove the major anomaly, and one of the possible elements given is the refractive effect of the planetary atmosphere on light.
There are also many refractions of sunlight rays hitting the earth, so when the light of one planet passes through the periphery of another planet, it will also be refracted as soon as it rises. Illustrate. There are 2 balls of different sizes on a tight eraser blanket, the large quality ball makes the rubber blanket dent a lot, and the smaller ball will roll towards the big ball, when the round ball fitness luck laughs back to the speed is very fast, it will not fall on the big ball, but will move around the big ball.
To people, it seems that there is an inexplicable attraction pulling them, but in fact, the interior space has been bent.

Theoretically, the gravitational pull of any celestial body can bend light, but the degree of bending is not the same, taking our sun as an example, at the time of a total solar eclipse, you will find that the position of the stars near the sun has changed, and the focus of the sun's gravitational lensing is about 1000 astronomical units (light years) from the sun. In the general theory of relativity, it is believed that the essence of gravity is the curvature of space, but in a weak gravitational field, the gravitational phenomenon can be approximated by the law of gravitation, Einstein originally predicted the angle of deflection of light rays when they suddenly approached by the sun's finger.
-
It has to be at least 100 million light-years. Mainly from the universe. Changes in the universe and planets cause gravity to bend light.
-
Most celestial bodies can bend light, and this gravitational attraction is the core of a celestial body, such as the Earth's core.

The principle of bending light in the force field is one of the important contents of Einstein's general theory of relativity. According to the general theory of relativity, mass and energy bend space-time, forming what is known as a gravitational field. In the gravitational field, the propagation path of light rays is also affected, resulting in the so-called bending of light.
The phenomenon of bending light was first discovered by British astronomer Owen Stravinsky during his observations of a solar eclipse in 1919. Stravinsky successfully demonstrated the bending theory of light rays in Einstein's general theory of relativity by using the bending of light by the sun's gravitational field during a solar eclipse.
According to the general theory of relativity and the theory of bending of light, when a ray of light passes through a gravitational field, it travels along a curved path, and the degree of bending of the ray is related to the strength of the gravitational field. If the gravitational field is less intense, the path of the rays is less curved; If the gravitational field is stronger, the path of the rays is also more curved.
The discovery and theoretical explanation of the phenomenon of light bending are of great significance for the verification and development of general relativity. It not only proved that the gravitational field does bend space-time and light, but also provided important theoretical support for the emergence of major scientific achievements such as the black hole theory.
In short, the principle of bending light in the gravitational field is one of the important contents of Einstein's general theory of relativity. It reveals the influence of gravitational field on space-time and light, and provides important theoretical support for scientific research and technical applications.

Does gravity change the speed of light? What a question! But before I use Gordon's theory of everything, I'd like to ask a few more questions.
Do physicists know how gravitational fields are created? We know what produces the gravitational field (mass), but we don't know the mechanism by which the gravitational field is generated.
Why does gravitational field affect light? It is hypothesized that mass bends space-time, creating a gravitational field, but physicists are not yet aware of this mechanism.
It is well known that the gravitational field affects the passage of time, but its mechanism is still unknown, and it is only understood that it is the correct observation and the mathematical way to interpret this observation.
What I'm medium-sized trying to figure out is ......There are many missing pieces in this puzzle. The missing piece is not missing in Gordon's theory of all things so keep that in mind and I'll have your question.
Gordon's theory of everything reveals that all energy in the universe exists in three Gordon states. Physicists know only two of these energy states, the energy of mass (proportional to C2) and the energy of light (proportional to C1). The fundamental energy state is the energy associated with the structure of space-time itself, which is proportional to c 0.
Light is moving energy at a speed of c 1 and the energy passing through space-time is proportional to c 0. Gordon's theory of all things defines the speed of light as the speed at which energy must move through energy to maintain Gordon's energy state.
Let's start by imagining that our universe has no matter, only light and space-time (two Gordon states). The e0 energy along the path determines the speed at which the light energy travels through the path. Light moves a certain amount of energy within a quantum unit of time.
Thus, the e0 energy determines the "relative" quantum distance. Quantum distance is the distance traveled by light in one quantum unit of time. (Note that the ratio of quantum distance to quantum time units must always be equal to 1.)
>Since quantum distances are relative, the speed of light is also relative....But measuring the speed of light in any space-time, regardless of the E0 energy concentration along the path, it is always measured as c 0. Physicists don't know the e0 energy of space-time because it is inaccessible, but it is this energy that determines the existence of the speed of light.
Now that we have determined the speed at which light passes through energy, let's add the e2 energy of the mass. Physicists don't know this either, but all energy fields are generated by the interaction of e1 and e2 energies with potential space-time e0 energies. Particles containing mass extend the E2 energy field indefinitely.
The gravitational field is the coexistence of E2 energy with space-time.
Now, you have the answer ...... your questionLight slows down in the gravitational field because there is more energy in its path. The energy along the path can be any energy of any Gordon energy state. The bending of light (and what determines "straightness") depends on the presence or absence of an energy gradient, i.e., the photon has less energy on one side of the path than on the other.
-
It changes the speed of the light because after the light is bent, its resistance increases and the speed slows down.
-
Yes, it changes the speed of light, scientists have demonstrated.
-
The speed of light is immutable, that is, the speed of light is a fixed value, and there is no such thing as fast light and slow light. The existence of the speed of light is actually a cosmic constant, which will not be accelerated or slowed down by the Zheng Yu environment in which it is located or by the influence of some external forces. Therefore, gravity cannot change the speed of light.

The so-called spatial curvature is not the deformation of rigid matter in the macroscopic world, so there is no absolute vacuum due to the curvature of space, that is, there is no problem of filling space.
The so-called space is the physical background that affects the existence of objects and restricts the movement of matter. Different physical backgrounds are made up of different particles, and they can have different effects on different substances.
For example, the movement of a ship is affected by water, while the movement of a car creates wind resistance. Water and air are made up of water molecules and gas molecules, mainly oxygen and nitrogen, respectively.
The smaller the particle, the more fundamental the physical context in which it is formed, and the greater the extent to which it is affected by that space. Since the universe is a part of nature, it is a concrete and finite closed system. So, in our universe, there are the smallest particles that are indivisible.
This particle is a quantum defined by Planck's constant h, which forms the basic unit of energy.
Therefore, the physical background composed of quantum is the most basic physical space of our universe, and it is also the basic form of the existence of the universe. Matter, on the other hand, is just a closed system formed by the aggregation of local high-energy quantum space, similar to the foam of seawater, and its state of existence depends on the collision of space quanta.
As a result, imbalances like water or air will form turbulence and cyclones, and the symmetry of quantum space will also be broken due to the existence of matter, so that matter will drift to maintain the symmetry of quantum collisions in space.
For example, as a closed system, matter will radiate heat energy to the outside world because of their closed nature between 0 and 1, causing a thermal gradient distribution in quantum space. Its essence is the asymmetrical distribution of space quanta, which is vividly compared to the curvature of space.
As a result, the space quantum between the two objects has higher energy and thus greater penetration, so that the space quantum collisions on the outer side of the two objects are more than the quantum collisions on their inner side. The resulting pressure difference is known as gravitational force.
In fact, the essence of all the interacting forces in nature is due to the unbalanced distribution of quantum space caused by the existence of matter, which in turn affects the state of existence of matter, which is manifested as being acted by force. However, different effects on quantum space will produce different distributions, and thus different forces will be formed.
In short, the curved limbs of space are just a metaphor for the asymmetrical distribution of discrete quantum space, which is not fundamentally different from the flow of water and the wind. Gravity is just one of the many ways in which quantum space asymmetry can occur due to the presence of matter. The essence of gravity is that it is an apparent phenomenon caused by the asymmetric collision of objects in quantum space, which does not exist in itself.
Space-time exists objectively, and when a substance is put into a space-time, it will have an effect on the entire space-time, because it occupies a piece of space-time. >>>More
I think the gravitational pull of the earth is natural. Without gravity, anything in the universe would be zero. Because there is no such thing as an independent thing or the only thing, the existence of every thing in the universe depends on the existence of objective things, and this dependence is gravity. >>>More
Hehe, this boy is so humorous, what you said is quite reasonable, let me add, why are the fingers bent in space. When the fingers are straightened or the fist is clenched, there is always one side of the skeletal muscle that will contract, so as the person above said, in order to save energy, people will instinctively let the organs that do not work at a low energy consumption level in the process of evolution, so just bend the fingers, and the skeletal muscles on the palmar and dorsal sides do not have to contract hard. >>>More
It is perfectly possible to conduct experiments on the bending of light on the theory of general relativity on Earth. Theoretically, any non-inertial system can bend light. The gravitational acceleration of the Earth itself also bends light, but it is too small to measure. >>>More
