Black holes can inhale light, so why do they say they change the direction of light?

In fact, the gravitational pull of a black hole is so strong that it will bend light that travels in a straight line, but any massive object can bend light, which is a problem with the gravitational field, but it does not necessarily suck it in.

Every black hole has a tipping point, and only after this point can it happen that even light can't escape. And this frontage is generally very small.

Suppose there is a black hole with the same mass as the Sun at the position of the Sun, what will happen to our Earth? Many people's first reaction is that the earth will be sucked in. Wrong, the Sun-mass black hole is only about 11 kilometers away from the center of the black hole, that is, only within 11 kilometers of the center of the black hole will the light be sucked in, and after 11 kilometers, the light is only bent below.

It's going to be fine.

If a super-large black hole, a black hole with 100,000 times the mass of the sun, its critical point is only about 4 lightseconds away, which is almost impossible to consider in the universe. It takes a minute for sunlight to travel from the sun to the earth.

So it is possible to bend light, but it is more difficult to eat light.

If the light is directly attacked, it will be sucked in, but if the light that is emitted outside the black hole will not be attracted to it, but will deflect its straight track, and the gravitational field of the black hole will bend, and when the gravitational field is out, it will become a straight line

As soon as light gets close to the black hole to a certain extent, it changes direction and is sucked into the black hole.

Feeling is related to the refraction of light, light can't feel the force, it's the speed limit!

If you want to suck in, you have to change the direction of the distance, can you go in if you don't change the direction?

Black holes are completely dark objects that astronomers cannot observe using optical telescopes, and their collisions are even more difficult to observe because the black holes themselves are difficult to observe.

However, an observation released by NASA suggests that the Palomar Observatory in California may observe optical signals from the merger of black holes.

The search for black holes and the discovery of black hole mergers have long relied on gravitational waves, which are spatial ripples proposed by Einstein's general theory of relativity, and the collision of supermassive objects such as black holes or neutron stars can produce huge gravitational waves. Gravitational waves were confirmed in 2015 as a new way for humans to explore the universe.

Black holes have a huge gravitational pull, and it is difficult for light to escape from black holes, so astronomers cannot directly observe the phenomenon of black hole merger, and can only speculate on the possibility of black hole merger through various signs produced after black hole merger.

The merger of black holes will first produce a strong gravitational wave phenomenon, which can even affect the entire universe, but the gravitational wave is very weak, and the gravitational wave close to the merger area of the black hole may tear the celestial body, but it is difficult to feel the gravitational wave at a distance of 10 kilometers from the merger area of the black hole.

Before the scientists observed the light signal, many astronomical observatories detected gravitational waves in advance, and characterized the event as a black hole collision merger, and the impact event was named GW190521G.

After confirming the gravitational wave event, the Palomar Observatory used special observation equipment to observe an optical signal in the region, which scientists believe is likely to collide with a black hole.

Although the black hole itself does not produce light signals, and the huge gravitational pull of the black hole makes it difficult for a large number of light signals to propagate to the outside world, the collision of the black hole will also cause the surrounding gravitational anomaly, which in turn causes various materials around the black hole to collide and produce light signals.

The optical signal discovered by the Palomar Observatory is likely to be produced by an impact of a celestial body near a black hole. Black holes have a huge gravitational pull, and around them, more matter tends to accumulate. When two black holes merge and collide, the black hole forms a binary star system at the same time, and the material around the silver hole also collides frequently, which in turn generates light signals.

The merger of black holes produces gravitational waves, and scientists have been searching for evidence of this.

If the visible light is indeed a light signal produced by the merger of black holes, and scientists have also detected gravitational waves, then it can be used as one of the evidence that black holes merge to produce gravitational waves.

Light signals are the most direct way for humans to explore the universe, and they can directly observe the universe and get the information they need.

Black holes, as the ultimate objects of human physics, have many mysteries and are also very difficult to observe. Being able to observe various events of black holes or black holes using optical signals can help scientists solve various mysteries of black holes faster.

Because when they collide, a lot of particles may be released, so some particles will cause friction and some light will be produced.

The reason why a black hole collision can produce light is that when two black holes collide in phase beams, when the black hole forms a binary star system, the matter around the black hole will frequently produce light, which in turn leads to the generation of light signals.

Because black holes collide and produce a certain amount of energy, which is converted into the form of light, so we see light.

<>Although we have obtained the first black hole**, we cannot observe the results of the light and matter that fall into the front of the black hole due to the blocking of the event horizon. However, Einstein's theory of general relativity allows us to make reasonable assumptions about the interior of black holes, after all, general relativity has successfully predicted the existence of black holes.

Theoretically, a black hole has no substance, the surface of the black hole or the event horizon is empty space, and the center is a singularity that contains all the mass of the black hole. Once the light crosses the event horizon and enters the interior of the black hole, they will travel along the curved space to the black hole's singularity, and their energy will add mass to the black hole. If there is a light source inside the black hole, then the light emitted by the light source will eventually fall into the singularity along the curved space, and it is impossible to escape the event horizon.

Therefore, the black hole itself is completely black, and we cannot observe the black hole without light being emitted. Unless the black hole is engulfing a cloud of gas, the matter moving around the black hole forms a glowing accretion disk that allows the black hole's shadow to be revealed, as was the first real black hole** in history. The accretion disk of the M87* supermassive black hole spans up to light years, or trillion kilometers, or 10,000 times the distance between the Sun and the Earth, and even though it is 54 million light-years away, we can still capture the shadow of the black hole on Earth through radio telescopes.

In addition, the question of light entering a black hole also involves the black hole information paradox. Light carries information, and what happens to the information when it enters the black hole?

According to quantum mechanics, all processes can be inverted in time, so the information after entering the black hole should also be able to be preserved. According to Hawking radiation, the black hole itself will constantly lose mass and eventually disappear into the universe. The black hole's homingold radiation is random, which causes the black hole to lose the information it contains, thus contradicting quantum physics.

Since we have no way of knowing what is going on inside a black hole, it is currently impossible to solve the black hole information paradox. There are several possible explanations, one is that the information is really completely lost; The other is that information escapes from inside a black hole into other parallel universes; Another is that Hawking radiation may not be completely random, and if we throw an encyclopedia into a black hole, we might be able to reconstruct the book in Hawking radiation. To solve this paradox, further research on black holes is needed, and a breakthrough in the theory of quantum gravity is needed.

The light sucked in by the black hole will be converted into the energy of the black hole and stored, and when the energy of the black hole is too large to accommodate Pi Youna, it will inevitably emit gamma-ray bursts at both ends, and the light will not be able to see the light after entering the black hole, and it will not be able to see the changes in the light in the black hole.

After the black hole absorbs the light, the photons move in the hollow and curved space inside the black hole, and finally the photons are squeezed by the black hole into smaller particles, and then merge into the center of the black hole.

Through the research of scientists, it has been found that black holes can swallow everything, and light will also be swallowed by black holes, transforming them into three physical quantities: mass, charge and angular mass.

When light is sucked into a black hole, it will exhibit a change in the energy of one of mass, angular momentum, and charge, because there are only three kinds of mass in any black hole. No matter what matter is sucked into a black hole, this change will occur.

There are only three types of energy inside a black hole, and light is not one of them, so when light is absorbed by the black hole, it is first broken down into a form of energy that the black hole can absorb, and then converted into angular energy.

According to the theory of relativity, any object that enters a black hole will fall into the black hole singularity, which has a strong gravitational pull and can shatter all matter, even bending space and time, while light outside the black hole's event horizon will be bent powerfully.

After the light is sucked into the black hole, it will be decomposed into basic physical quantities such as mass, nuclear charge, etc., which is a theory that scientists have come up with through research and has a certain reference value.

I really wish you progress, if you have any doubts, please ask, and if it helps you, please don't forget to adopt it!

When light enters a black hole, it no longer exists.
