Why can black holes distort light, and can black holes distort space time?

Light is an electromagnetic wave, it has no mass, and it is precisely because it has no mass, that it can reach the speed of light, and the higher the velocity of a matter with mass, the mass will increase (extremely high velocity), and increasing its speed will require more energy, and when it is close to the speed of light, the mass will become infinite, and it will require infinite energy, so light has no mass, it is essentially an electromagnetic wave, and light also has the properties of a particle, and because it is an electromagnetic wave, it has energy.

Light travels in space, and because the huge mass of the black hole distorts the surrounding space into a vortex, the light travels in this vortex and cannot be reflected back, so it gives people the feeling that the light is sucked into the black hole, and the light cannot be transmitted when it runs into the event horizon of the black hole (the boundary of the black hole), and it is not sucked in. Because the space near the horizon of the black hole is also distorted, the light travels through the distorted space, so we can see the starry sky behind the black hole, and the escape theory The escape speed of the black hole exceeds the speed of light, so the light emitted by the black hole itself cannot propagate (according to my understanding, it is still because the space is extremely distorted, and the light emitted by the black hole itself cannot come out of the distorted space), giving people the illusion that the light itself is sucked in, which is actually the result of the distortion of the space of the light propagation medium.

The huge mass of a black hole causes the space around it to bend, and the light naturally travels along the curved space, as if the black hole attracts light, causing it to distort and twist. Otherwise, let's take a look

Black holes can travel through, but they can't be twisted.

In fact, his black hole is not as scary as its name. In the case of black holes, if we humans are unfortunately inhaled, our body will stretch infinitely, but we will not feel pain, because it is not a distortion of matter, but the distortion of time and space, the degree of distortion depends on the density of the black hole, that is, the degree to which we are stretched by time and space. A black hole can easily be imagined as a large black hole, but it is not.

The so-called black hole is one such celestial body, because its gravitational field is so strong that not even light can escape. According to the general theory of relativity, the gravitational field bends space-time. When a star is large in size, its gravitational field has little effect on time and space, and light emitted from a point on the star's surface can be emitted in a straight line in any direction.

The smaller the radius of a star, the greater its effect on the curvature of space-time around it, and the light emitted at certain angles will return to the star's surface along the curved space.

I've previously described in detail the formation of white dwarfs and neutron stars, when a star ages, its thermonuclear reaction has exhausted the fuel in the center, which does not produce much energy. In this way, it no longer has enough strength to withstand the enormous weight of the shell. Thus, under the weight of the shell, the core begins to collapse until a small, dense star finally forms, which again has the ability to balance with the pressure.

Stars with less mass mainly evolve into white dwarfs, and stars with more mass may form neutron stars. According to scientists' calculations, the total mass of a neutron star cannot exceed three times the mass of the Sun. If this value is exceeded, then there is no force to compete with its own gravity, leading to another big crash problem.

Moreover, according to the speculation of scientists, the problem of matter cannot be controlled by us artificially, because his goal is to move towards the center point of the earth, and downstream until it becomes a point where the volume tends to zero, then its density tends to the point of infinity.

According to existing research, it is believed that black holes can travel but cannot be distorted. Black holes can stretch our bodies infinitely, but we don't feel pain, because it's a distortion of time and space, and distortion depends on the density of the black hole, it's not a distortion of matter.

Yes, the presence of a black hole can distort the surrounding space exceedingly. Because according to the general theory of relativity, light rays travel in a straight line in normal space, but when space warps, the light rays distort with the direction of the space warp.

The reason for the occurrence of gravitational force (brief description): When the high-energy particles moving in the universe pass through matter (celestial bodies or particles), part of them are intercepted and absorbed to form a weak energy region (Einstein's space-time curvature), which is the gravitational range mv2=e=mv2 (the formula of the law of conservation of energy conversion). For more details, please see the forthcoming gravitational hypothesis, "Elemental Periods and the Causes of Gravitation".

If we are unfortunate enough to be sucked into a black hole, our bodies will be stretched infinitely without pain, so we can travel through but not distort time and space.

In the words of the head of the group, a person with the characteristics of a black hole is a person who can suck the energy of others. And people with the characteristics of luminous bodies will use their own power to emit light that people can't help but want to draw and get closer. Staying with people with luminous qualities will make you feel comfortable and warm, while people with black hole constitutions can't help but make people want to escape, so how to make a luminous body?

Everyone has their own ways and characteristics that are suitable for each person, and finding the most suitable way for me is a compulsory course for me in my life.

Looking at the circle of friends in the past, I feel that I am complaining a lot of the time, complaining about people, complaining about things, complaining about things, maybe I didn't think there was anything at that time. But when I look at these past moments of friends from the perspective of a bystander, I find that I can't stand it, because there are so many negative emotions emanating from the language that people go from sympathy at the beginning to disgust at the back. Looking through the past, I'm glad I saw the problems in the past, maybe at the age at that time, the environment at that time is the characteristics that this age should have.

The question of how to make myself a luminous person, there may not be an accurate answer to me, but I think I am already beginning to discover and correct it from myself. Even if I can't become a luminous body, try to stay away from the black hole physique and strive to become a luminous body, which is a compulsory lesson and direction for me to do in my life! Share!

After the star burns out the fuel in the core, there is no strength to resist gravity, it begins to contract violently, and a supernova explosion occurs, and the core contracts until the black hole is formed and falls into the black hole, there is no other force in the black hole that can resist gravity, everything can only be compressed, stretched, and finally fall into the singularity, which is quite terrifying!

As for the volume of a black hole, it usually describes the size of the black hole's event horizon. The event horizon is not at all like our ground, it is not a solid surface, but a boundary between time and space: objects outside the event horizon can see and leave the black hole; Objects within the horizon are invisible, and only.

Black holes are formed by massive stars at the end of their lives, and it is generally believed that stars with more than 20 times the mass of the sun form black holes, after the stars burn up the fuel of the core, they have no strength to resist gravity, they begin to contract violently, and supernova explosions occur, the core has been contracting, until the black hole is formed, falling into the black hole, there is no other force in the black hole to resist gravity, anything can only be compressed, elongated, and finally fall into the singularity, quite terrifying!

As for the volume of a black hole, it usually describes the size of the black hole's event horizon. The event horizon is not at all like our ground, it is not a solid surface, but a boundary between time and space: objects outside the event horizon can see and leave the black hole; Objects within the field of vision are invisible, and can only fall into the singularity.

When a star ages, its thermonuclear reaction has exhausted the fuel (hydrogen) of the center, and there is not much energy produced by the center. In this way, it no longer has enough strength to carry the enormous weight of the shell. So under the weight of the shell, the core begins to collapse until it finally forms a small, dense star that regains its ability to balance with the pressure.

Stars with less mass mainly evolve into white dwarfs, while stars with more mass may form neutron stars. And according to the calculations of scientists, the total mass of a neutron star cannot be greater than three times the mass of the Sun. If this value is exceeded, there will be no force left to compete with its gravity, causing another collapse.

This time, according to scientists' conjectures, matter will march inexorably towards the central point until it becomes a very small volume and a very dense tendency. And when its radius shrinks to a certain point (it must be smaller than the Schwarzschild radius), as we described above, the huge gravitational pull makes it impossible for even light to shoot out, thus cutting off all contact between the star and the outside world - the "black hole" is born.

Because the gravitational pull of Suichun can bend light. Due to the bending of light, phenomena such as negative refraction and gravitational lensing are produced. You may ask how a massless photon is affected by gravity. It's not just the case of black holes, but every object can bend light.

Because gravity can bend light, and the black hole hides a huge gravitational field, this gravitational force is so strong that anything, even the light seeps, can not escape the palm of the black hole, so the light bends around the black hole, and inside the black hole we can't see the light.

Because black holes can swallow light. So instead of bending around the black hole, a part of the light is swallowed up and looks like a bend.

The masslessness of a photon is only a case at rest, but this is only a virtual hypothetical state, light is both a wave and a particle, and it is impossible to observe if the photon does not move. As long as it moves, it will have mass, and the speed of photons is the speed of light, and the value of the speed of light in a vacuum is c 299 792 458 m seconds, but the cosmic environment is not strictly speaking a vacuum, because there is a large amount of interstellar dust, interstellar particles and interstellar magnetic fields, so the actual speed of photons should be slightly slower than this value.

Since the speed of photons cannot reach more than 299 792 458 meters and seconds, then use this value to compare the second cosmic velocity of black holes, the density of the earth is grams per cubic centimeter, and the density difference of black holes is 15 billion tons per cubic centimeter, the density difference alone is already more than 2,000 trillion times, and the second cosmic speed of the earth, that is, the speed of escaping from the earth, is 11,200 meters and seconds. I have read some data such as the mass volume of a black hole in books about the universe, and it is roughly calculated that its escape speed can reach 500 times that c, according to the theory, this speed cannot be reached, so it is normal for light to not escape from the black hole, even if the black hole itself can emit light, it is closed by its own strong magnetic field, and we naturally cannot see it.

Explanation: There is a huge difference between Einstein's universe and the classical mechanics that preceded it.

In Newton's time, time and space were uniform, which meant that time passed in you as much as anyone else, and the space you were in was no different from the space that others were in. But Newton's theory does not solve all the problems of motion, and it completely fails in cosmology and quantum science (you can look it up). Albert Einstein believed that everyone had to measure his time with his own clock (all because of the constant speed of light).

At the time, people thought he was, and I started to think so. Later, his theories were consistent with all the observations. People are slowly coming to accept.

The black hole bends the space-time around it, so that light is still taking the nearest route (in four-dimensional space, a straight line in three-dimensional space is not the closest path from one point to another).

This is difficult for college students to understand. As a side note, if we are fish in a tank, we can only formulate theories by the phenomena we see from inside the tank.

And when I say that, the landlord probably understands why light can't escape a black hole because time stands still in the horizon.

As for the quality of light, light has no intrinsic mass, and all objects with intrinsic mass cannot reach the speed of light, and the mass of light is only the mass that is produced by speed.

The light at rest mass is 0, there is mass in motion, so it cannot escape the gravitational pull of the black hole, and the moving mass can be calculated using the mass-energy conversion equation.

m=e (c 2)=h*f (c 2), where h is Planck's constant, f is the frequency of light, and c is the speed of light, then the mass of the quantum in motion can be calculated.

I never believed in science now.

A black hole is not a phenomenon, it is a real celestial body, the density is close to infinity, the gravitational field formed is very strong, the speed of the surface (the first cosmic velocity) is greater than the speed of light, and the light also knows that it cannot escape its gravitational pull, and it is also swallowed by the black hole, so if we see it, it is pitch black. Therefore, it is called a black hole, and it is a celestial body, not a phenomenon. Pure handwriting without copying lz to appreciate the face.

Black holes are the final stage in the evolution of stars.

The gravitational pull of a black hole can't even escape light, so it means that it can be used to tunnel space-time. Because the generalized sense is relatively mentioned, any object can travel through time as long as it reaches the speed of light! Black holes may cause large ** (Tunguska big ** has the black hole hypothesis).
