A black hole that eats everything, is there anything it can t eat?

Black holes, "notorious" for their super-strong and super-terrifying gravitational pull. Its gravitational pull is so great that even the light is helpless. But black holes don't swallow everything happily.

There are some things that black holes can also be difficult to deal with. So, what is so sacred that even black holes feel intractable?

This is the virtual particle. According to Heisenberg's uncertainty principle, a pair of positive and negative virtual particles suddenly appear in the universe.

The so-called virtual here is not a fiction, but a particle that really exists. According to scientists' observations of the universe, the energy in the universe is constantly fluctuating at any time, which is one proof of this. Due to the principle of conservation of energy, these two particles will annihilate when they meet together, so they appear very suddenly and disappear very suddenly.

And if the pair of particles appears near a black hole, it will be interesting.

According to the speculation of the famous physicist Stephen Hawking, when a pair of virtual particles appear near the black hole, the black hole will begin to swallow with its super gravitational pull. However, Hawking argues that black holes, despite their enormous gravitational pull, do not eat all two particles, but only one.

Since these are a pair of opposite particles, the other particle will fly away from the black hole in the opposite direction as one of them accelerates towards the black hole. Viewed from a distance, it looks like a black hole is spewing out large strands of energy. This phenomenon is known as Hawking radiation.

The problems don't stop there. Since the particle accelerates away from the black hole, it proves that it is under the action of the force. In this system, the one that can provide external forces is the black hole.

To provide force means to provide energy.

Scientists believe that this process is actually a process that consumes the energy of a black hole. In other words, black holes not only absorb energy, but also release energy into space. So, will the black hole one day release all the energy and hollow out its own body?

According to scientists' speculation, as energy is consumed, the black hole gradually shrinks, and the energy consumption leads to an increase in temperature. The energy of the black hole is constantly consumed, and the black hole also changes from a state of devouring all the matter around it to releasing energy outward. When the black hole consumes all the energy in its body, a huge ** will occur, and at the same time, it will release dazzling light, and it will disappear into the universe.

At the same time, we also need to consider that black holes do not simply release energy, but also absorb it. Not to mention whether the energy of the inhaled negative energy antiparticles will be absorbed, just absorbing the surrounding light, celestial bodies, etc., is enough to provide a huge amount of energy to the black hole.

And this energy may grow much faster than if it were given to positive particles.

Anything that enters a black hole cannot escape, not even light, but a black hole cannot eat a black hole.

There is no scientific evidence to prove this. Because until now, we humans or space technology have not been able to get close to black holes, we can only say that black holes do have a huge attraction and can absorb stars into it, but there is no way to say what it can't adsorb!

A pair of positive and negative particles near a black hole, where the antiparticles may be sucked in by the black hole and the positive particles fly away. Also known as Hawking radiation. So black holes are foodies, but there are times when they have indigestion.

Black holes are one of the most mysterious and terrifying beings in the universe, and they have a huge gravitational pull that can swallow everything into them. However, a black hole cannot eat all the planets, it has some limitations. First, a black hole can only swallow matter that is close to it, and if the planet is too far away from the black hole, then it can safely exist.

In addition, black holes can only swallow matter that is caught by gravitational capture, which means that only planets that are too close to the black hole to escape will be swallowed. If the planet orbits farther away, then it will not be affected by black holes.

Second, black holes also don't work for some specific types of planets. For example, some planets contain too much gas in their composition, and if they land in a black hole, they will be burned up due to friction and cannot enter the black hole. In addition, some rare planets with heavy elements are also protected from the threat of black holes due to their composition and distribution.

This is because the material composition of these planets is not the same as that of other planets, and they are not easily captured by black holes.

In short, despite its mysterious gravitational pull, black holes also have many limitations. One should not worry too much about the threat of a black hole to the universe and humanity, as it also needs to meet some specific conditions in order for it to work. At the same time, studying black holes can help us better understand the evolution and development of the universe and reveal which planets and matter are more susceptible to the effects of black holes.

A black hole cannot absorb a planet with the same mass.

Black hole is a kind of celestial body in the universe in the modern general theory of relativity, and the gravitational pull of the black hole is very large, so that the escape speed in the event horizon is greater than the speed of light, and it is a celestial object with a curvature of space-time that no light can escape from its event horizon.

In 1916, the German astronomer Carl Schwarzschild calculated a vacuum solution of Einstein's field equation, which showed that if the actual radius of a static spherically symmetric star is less than a fixed value, a strange phenomenon will occur around it, that is, there is an interface - "event horizon", once entering this interface, even light cannot escape.

This value is called the Schwarzschild radius, and this "incredible celestial body" was named a "black hole" by the American physicist John Archibald Wheeler, and the black hole cannot be directly observed, but its existence and mass can be known indirectly, and its effects on other things can be observed. Information about the existence of a black hole can be obtained by emitting X-rays and "edge information rent" of rays due to friction caused by the acceleration caused by the gravitational pull of the black hole before the object is sucked in.

Introduction to the evolution process of black holes:

A black hole is a singularity with infinite density, infinite curvature of space-time, infinitely small volume, and infinite heat in the center, and a part of the surrounding empty celestial region, which is not visible within the scope of this celestial region. According to Albert Einstein's theory of relativity, when a dying star collapses, it will gather into a point where it will become a black hole, swallowing all light and any matter in the adjacent cosmic region.

The creation of a black hole is similar to that of a neutron star: when a star is preparing to perish, the core of a star rapidly shrinks and collapses under the force of its own gravity. When all the matter in the core turns into neutrons, the contraction process immediately stops, and it is compressed into a dense star, which also compresses the space and time inside.

But in the case of black holes, the mass of the star's core is so large that the contraction process goes on endlessly, and even the repulsion between neutrons cannot be stopped. The neutrons themselves are crushed into powder by the attraction of the squeezing gravity itself, leaving behind a material of unimaginably high density. The gravitational pull of the roll is created due to the high quality, so that any object that comes close to it will be sucked into it.

Black holes can devour all objects, and black holes are very dense planets;

The black hole has a huge gravitational pull, even the light is attracted by it, the black hole hides a huge gravitational field, the black hole does not let anything within its boundaries be seen by the outside world, this is the reason why this kind of object is called a black hole, we can not observe it through the reflection of light, we can only understand the black hole indirectly through the surrounding objects affected by it, it is speculated that the black hole is the remnant of a dead star or a pure air mass, which is produced when a special massive supergiant collapses and contracts;

From the point of view of physics, the black hole is a kind of celestial body in the universe in the modern general theory of relativity, the gravitational pull of the black hole is very large, so that the escape speed in the event horizon is greater than the speed of light, in 1916, the German astronomer Karl Schwarzschild obtained a vacuum solution to the gravitational field equation of the Einstein by calculating the roller, this solution shows that if a large amount of matter is concentrated in a point in space, strange phenomena will occur around it.

Then the black hole will also starve to death, such a long-term lack of food. The stomach will also be very uncomfortable, and after a long time, it can really cause it to starve to death.

No. A black hole is not life, it is just a hole after the collapse of the star, it can exist for a long time and does not need to eat.

It is impossible for it to appear, and if it does not devour, it may not become larger and larger, and then it will affect its development, but it is not conscious of itself.

According to Hawking's theory, black holes have a type of radiation, known as Hawking radiation, which constantly emits its own mass, which means that if the black hole does not swallow matter, it will die.

When a particle falls towards the black hole horizon, not only does the black hole unilaterally interact with the particle, but the particle also has a gravitational pull on the black hole. Under the gravitational pull of particles, the Schwarzschild radius of a black hole will increase, rather than remain constant. Thus, in our view, distant observers, particles do not fall into a black hole after an infinite amount of time, but after a very short time scale.

Moreover, the observation of gravitational waves generated by the merger of black holes also supports this theory. If it seems to us that it takes an infinite amount of time for particles to fall into a black hole, the black holes we see today would be "frozen" outside the event horizon if accretion. When the black hole merges, it will emit an extremely large number of photons, which will be observed by us.

In fact, until now, humans have not observed the merger of two black holes in the optical band, which does not correspond to the frequency of events observed by Ligo. <>

First of all, it is necessary to clarify that there is no concept of gravity in the framework of the broad phase, and the gravitational force we feel is the embodiment of space-time distortion. Whether the Earth revolves around the Sun or an apple falls to the ground, it is only a "uniform linear motion" (formally called geodesic) in the geometry of space-time (under the influence of mass). For the sake of description, we still use the word "gravity".

Second, black holes come from a broad phase solution. The Schwarzschild solution is the simplest solution of the broad phase (spherical symmetry), and the gravitational force of the earth and the sun can be described by the Schwarzschild solution. Under the Schwarzschild solution, when the density of matter is high enough, no force can prevent the gravitational collapse of the matter, so the matter collapses into a singularity, forming a black hole (the singularity of the Schwarzschild solution is a point, and for the kerr black hole, a black hole with angular momentum, the singularity is a ring).

The Sun did not collapse because of the internal thermal pressure, but the Sun would not become a black hole if it lost its thermal pressure, but a white dwarf; The reason why the white dwarf does not collapse is because of the internal electron degeneracy pressure, but the white dwarf that cannot be supported by the electron degeneracy pressure does not necessarily become a black hole, but may be a neutron star; Neutron stars do not collapse because there is neutron degeneracy pressure inside, but there is no stronger pressure further up, so if the mass of the neutron star is greater than a certain upper limit (and therefore the density is greater than a certain upper limit), it will definitely collapse into a black hole. Under the theory of the broad phase, we have no choice but to admit the existence of black holes, although Einstein did not like the solution to black holes. Thirdly, white holes and wormholes may be interesting things, but neither is a serious topic, just a science fiction theme.

What cannot be proven or falsified does not fall under the umbrella of science. Finally, let's face the question: the Schwarzschild solution has two peculiar aspects:

One is the horizon and the other is the center. The horizon is also the infinite redshift plane, and the closer you get to the horizon to a distant observer, the slower the time will be, so that's the subject's problem. But note that time slows down for what a distant observer sees, so for a distant observer, it is never visible for a distant observer that matter falls within the event horizon, because time becomes infinitely slower when approaching the event horizon.

But in fact, both light and matter can effortlessly pass through the horizon and reach the interior of the horizon in their own coordinate systems. So the subject's question, did the substance fall into it? Of course, they fell in, and in the local time of matter, they passed through the horizon at once.

If you can look at "Interstellar", when Cooper uses the gravitational slingshot effect of the black hole, you can see that when the accretion material moves to the edge of the event horizon (as seen from the perspective of a distant observer), Cooper himself falls into the black hole and accelerates all the time and passes through the event horizon (in his own coordinate system) at once. So this ** shooting is still quite good, this kind of detail has been noted, after all, there is Kip Thorne as a scientific advisor. <>

Because. Energy is conserved, so black holes.

It can't be done in a vacuum.

By "eating" these things, we theoretically deduce that there may be a substance diametrically opposed to a black hole, called.

White hole.. White holes eject material incessantly, as opposed to black holes. And, what the white hole "spit out" may be.

Another universe.

Appear. If the white hole really exists, then the black hole can "eat" as much as the white hole can "spit out".

You can imagine that the black hole and the white hole are connected to a water pipe, how much water can this water pipe hold? If you keep putting water in, the water will keep coming out of the other end, so the total size of the outlet at the other end is the water that this pipe can hold.

Therefore, if the theory is true, the amount of food that a black hole can "eat" is exactly equal to the amount of matter that can exist in the universe corresponding to a white hole.

But if the hypothesis is not true, then, at the current level of science, I can only tell you sincerely: I don't know.
