Science Experiment Why Light Can t Escape Black Holes

It's actually very simple, it's not that the black hole slows down the light, or absorbs the light, in fact, the light is just trapped. As for the question of why light can't escape from black holes, my personal opinion is that galaxies and black holes are both natural objects that exist in the universe and orbit independently, and although they are related, they are in a state of non-interference. Why?

On the other hand, black holes are spontaneously combustible celestial bodies that exist in the universe and operate independently, and are the outer spaces that wrap around the countless galaxies in the universe, acting on the balance of independent movement and change of galaxies, and are netted celestial bodies with dark matter and dark energy that cannot be reached by the light of all stars in the universe, and can rotate and move in all galaxies in the universe, so that the black hole celestial bodies produce huge high-speed convection and vortex motion phenomena, and produce physical lens phenomena, which will make the light emitted by all stars in the universe lose its penetration. Shielded from any light penetration, the so-called "black hole" celestial phenomenon is formed.

It can be seen that galaxies and black holes are both natural objects that exist in the universe and operate independently, although they are related, they are in a state of non-interference with each other, so light cannot escape from black hole objects. I wonder if this is accurate?

From the point of view of Newtonian mechanics, the gravitational pull of this celestial body is too strong, attracting all the light and unable to escape. To use Einstein's theory of relativity, light is trapped in a self-enclosed gravitational trap and cannot escape. Each planet has its exit velocity, also known as the second cosmic velocity or escape velocity.

It is the speed required for an object to depart from the surface of a planet, get rid of the gravitational pull of a planet, and go to space. The second cosmic velocity of the Earth is kilometers and seconds. That is, if a spacecraft is launched from Earth, if its velocity reaches or exceeds the second, it can break free from the Earth's gravitational pull and become a spacecraft traveling in the solar system.

The second cosmic velocity of a planet is related to the mass and density of the planet. The greater the mass and the stronger the gravitational pull, the greater this velocity; For the same mass, the greater the density, the smaller the radius of the planet, the more concentrated the gravitational pull, and the greater the velocity. The mass, density, and radius of the Moon are smaller than those of the Earth, and its escape velocity is only a kilometer second, while the Sun is much larger than the Earth, so the Sun's escape velocity is as high as a kilometer second.

One can imagine a planet that is very dense, has a very small radius, and therefore has a very strong gravitational pull, and its escape speed is large enough to reach the speed of light. In this way, the light emanating from the surface of the planet cannot escape. Objects (including light) that enter the gravitational range of the planet from the outside world will no longer be able to escape the planet.

Well, from a distance, the planet does not glow, it is black. This is a black hole. This is the Newtonian interpretation of black holes.

In Einstein's view, mass can cause space-time to bend. The greater the mass, the more space-time bends. Then we can imagine a celestial body, which is massive enough to cause space-time curvature to bend a certain range of space-time to itself, so that a part of the space-time structure can self-enclose, so that all the matter inside (including light) cannot leave, and once the objects from the outside (including light) enter this closed area, they cannot leave again.

This makes this space-time region a gravitational trap in the universe, a bottomless pit. The boundary of this region is called the "event horizon" of the black hole. From a distance, this area is dark.

This is a black hole. This is the relativistic explanation of black holes. The r=2m or less in the figure below is such a space-time region.

It's a black hole.

Due to gravitational attraction, a certain velocity can escape from an object, for example, the earth has a first cosmic velocity, and a black hole is equivalent to the first cosmic velocity is the speed of light.

Because a black hole is a space of thought.

To put it simply, because the gravitational pull of a black hole is so great that no object can escape its gravitational pull, not even light. It can also be understood that black holes escape faster than the speed of light, so light cannot escape from black holes either. Only "faster-than-light" can escape the gravitational pull of a black hole, but in our four-dimensional space-time, there is no faster-than-light object.

According to the general theory of relativity, nothing can travel faster than light, so if even light can't escape, nothing else can escape. Everything will be pulled back by the gravitational field. The area where light and nothing can escape, we call it a black hole.

According to the interpretation of general relativity, the essence of gravity is the curvature of space-time, because black holes can stretch space-time results to the extreme, light propagation is actually along the curved space-time, when light propagates into the space-time structure that is stretched to the extreme, it takes an infinite amount of time for light to escape, which is obviously impossible. Because the gravitational field of a star alters the way light travels through space-time, it is different from what it would have been if there were no stars. In other words, the gravitational pull of the star changes the path of light, and if it were a very massive star like a black hole, the light would not be able to escape, but would be attracted back by the gravitational pull of the black hole.

Black holes are very strange celestial bodies derived from the general theory of relativity, and later astronomers affirmed that they really exist in the universe, and black holes were also photographed, which further proved the correctness of the general theory of relativity.

As long as we do not cross the event horizon and insist fast enough, we can escape the strong gravitational pull of the black hole, and once we reach or cross the event horizon, as long as we "go and have no return", we will be swallowed by the black hole and completely become a part of the black hole. As for what is the situation inside the black hole, human beings do not know at present, because the horizon of things is the limit of what we can know, once the boundary is crossed, all the laws of nature that human beings continue to be invalidated will be invalid, and we can only imagine and guess the possible situation inside the black hole.

In essence, a black hole is also a celestial body, just a celestial body with great gravitational pull, a celestial body from which no matter can escape, and it can become a black hole even if the earth is reduced to a size of 9 millimeters in diameter!

Light cannot escape in a black hole. Because the gravitational pull of a black hole is so great that nothing can escape.

Light cannot escape in a black hole because the black hole is so big that it is simply endless. The light never comes out.

Light can't, light doesn't speed enough. Because the attraction of the black hole is so great, its speed exceeds the speed of light.

If light can't escape a black hole, then how did humans discover it? Although superblack holes cannot be directly observed, they can be observed indirectly, and the current basic theories are used to infer the existence of superblack holes and calculate their quality.

Because of the huge attraction of super black holes, the light (radio waves) in the field of vision cannot come out, and it is difficult to observe without light. However, when experts observed the stars near the middle of the solar system, they found that the orbits of the planets in that place were very extreme, not similar to a circular ellipse, the orbital plane was elongated, and the planets were particularly fast when they orbited to the "perigee", reaching more than 5,000 kilometers per second, and the orbital period was only 15 years, but their central stars were "invisible", located at a focal point of the elliptical orbit, and according to the current basic theory, the only star with that characteristic was a super black hole.

Experts deduce that the mass of the black hole in the middle of the solar system is 4 million solar masses, which is called Sagittarius A*. Black holes are some massive celestial bodies in the universe, and in the middle and late stages of evolution, there is no ability to block the attraction of matter, and when the half-longitude is lower than the Schwarzschild radius, the internal light cannot hit and run, and super black holes will be formed. The Schwarzschild radius on Earth is less than 10mm, and the Earth's current half-longitude is about 6,600 kilometers, which shows how large the relative density of super black holes is.

Newton felt that the attraction is essentially space-time curvature, but the curvature of space-time caused by a large and small star like a super black hole is even stronger, just like a ball of the same quality and volume in the same plastic film, the smaller ball "falls" more violently, in this kind of space-time, the nearby star only maintains a very fast start-up speed, and will not fall into the super black hole. Moreover, when the black hole is devoured, it will also release a lot of kinetic energy, which can be used in space to observe super black holes.

The main passage is through the X-ray source. It is also judged by the interference of the surrounding stars, through which the existence of black holes can be detected.

It was when we were studying the general theory of relativity that we discovered the Schwarzschild solution, which is why we discovered black holes.

It is determined by the interference of the surrounding planets, and now human beings also have a certain understanding of the universe.

It was discovered through the orbits of surrounding celestial bodies, and this idea has been confirmed. It's also quite reliable.

The main thing is to design some high-tech products that can observe black holes in this process, so that they can also hover around the black hole for a long time, and can also understand and observe some things about the black hole.

It is true that black holes cannot be observed, but the phenomena produced by the gravitational pull of black holes can be observed by scientists: (1) binary accretion, that is, the accretion of black holes to surrounding stars. (2) The gravitational pull of a black hole is close to infinity, and the light of a star is bent very strongly, and the gravitational lens produced allows us to see the whole picture of the star, even if we can never see the back of the star without the help of the black hole.

3) Black hole accretional material produces very powerful X-ray bursts. It is through these phenomena that our scientists can calculate and infer whether it is a black hole or not.

Black holes are mainly observed through some technology, and the impact of black holes is very large, so it has not been seen clearly until now.

Summary. According to existing astronomical theories, a black hole of any mass has a gravitational field sufficient to attract and prevent light from escaping. This means that even very small black holes can become "traps" for light, making it impossible to escape.

And, according to the black hole's concept of an "event horizon", no object at a certain distance from the black hole's surface can escape the black hole's gravitational pull, including light. The event horizon distance depends on the mass of the black hole, and the larger the black hole, the greater the event horizon distance and the wider the engulfing range. Therefore, according to the current scientific theories, a black hole of any mass can cause light to be unable to escape <>

To put it bluntly: a black hole is an infinite mass and dense celestial body, with a very strong gravitational pull that makes it impossible for light to escape. Is this statement correct?

Dear, this statement is correct, oh <>

Aren't there many types of black holes? And not all black holes are infinitely dense in mass.

There are three types of black holes known to exist in the universe: primordial black holes, stellar black holes, and supermassive black holes.

Not all black hole mass densities are infinite. The mass density of a black hole is the ratio of the mass of the black hole to its volume, so the larger the mass and the smaller the volume, the greater the mass density of the black hole. There is a theoretical type of black hole called a "miniature black hole", which has a very small mass but a very high density.

And ordinary stellar-mass black holes, although also very dense, are not infinite. The mass density of a black hole depends on its mass and volume, and different types of black holes will have different mass densities.

In conclusion, the gravitational pull of a black hole is indeed so strong that light cannot escape. However, its mass density is not truly infinite, but very large.

How do you explain this? Could it be a special case?

According to current theories of physics, the lower limit of the mass of a black hole is the mass of a star, that is, about the mass of the sun.

The mass of a black hole refers to the total mass of the matter it contains, usually measured in terms of the mass of the sun.
