Is there really a singularity in a black hole? Why?

Of course, there is a singularity in a black hole. It is precisely because of the influence of the Schwarzschild singularity that the black hole has a huge gravitational pull that no other celestial body has so far been able to match. As we all know, black holes are arguably the most mysterious and threatening celestial objects discovered in the observable universe so far.

The destructive power of black holes is unquestionable; It can be said that any substance that falls within its Schwarzschild singularity has no chance of survival. Whether it is a photon traveling at the fastest speed in the universe, a neutron star, etc., everything is equal in front of a black hole.

So, where do black holes come from? The earliest human society recognized this mysterious celestial body from the "general theory of relativity" proposed by Albert Einstein a hundred years ago. General relativity understands the nature of gravity as a bend of space-time; Therefore, changes in the spatiotemporal environment can also lead to changes in gravity.

Schwarzschild, the famous American astronomer, thus deduced the so-called "Schwarzschild singularity". In the equation of general relativity, the collapse of a massive star creates a "Schwarzschild singularity". The Schwarzschild singularity is considered to be incompatible by any of the laws of physics, and the density and mass are inflated to a point of infinity.

Schwarzschild singularity, the origin of black holes. It is precisely because his rebellion against time and space has reached an immeasurable degree that black holes came into being. The center of the accretion disk of a black hole is a "Schwarzschild singularity".

It can be said that this is the consensus of all current black hole theories.

Of course, friends who may have known about this also know that the Schwarzschild singularity was also the source of the universe back then; The connection between the two has also aroused the reverie of some friends. For example, after a black hole has swallowed up a sufficient amount of matter, will the singularity inside it form a new universe as it did tens of billions of years ago?

This view is still a hypothesis. It can only be said that there are many scholars who agree with this theory, but it is not yet a consensus.

There is a singularity in a black hole. The state in the black hole is consistent with the state described by the singularity theory.

The interior of a black hole is almost completely unknown to humans. And there's nothing escaping from it that would allow us to understand it. According to the existing theories that are consistent with the current observed phenomena, there is a singularity inside the black hole, which is only a mathematical solution.

Of course, there is a singularity in the black hole, because the influence of the Schwarzschild singularity in the black hole gives the black hole a huge gravitational pull that no other celestial body has so far been able to reach.

At the singularity, all the laws and predictability are out of order. Singularities can be seen as edges or boundaries of space and time. Only given the boundary conditions at the singularity can the evolution of the universe be obtained from Einstein's equations.

In physics, singularities are also used to describe the situation at the center of a black hole. At this time, because the density of matter is extremely high, the infinite space is compressed and bent, and the matter is compressed at a very small point, and the denominator is infinitesimally small in the space-time equation at this moment, so the laws of physics are invalid.

Astrophysics, on the other hand, conceptually believes that the singularity is the state before the creation of the universe (that is, the "place of energy convergence" before the big **). As the "singularity of cosmology", it is the point at the beginning of the creation of the universe, from the ** that formed the present universe. It has the potential energy of all matter, and this potential energy is --- transformed into the mass and energy of matter in the universe by the big **.

and the "space" that expresses this quality and energy. We can imagine that singularity is an invisible, infinitesimal and wonderful existence. It is not yet the universe, but it is the beginning and origin of our universe.

Singularity. It is made up of pure hydrogen among the stars.

When consumed. The pressure will be out of balance.

Turn into a red supergiant.

However, if the mass of that star (more than 50 times the mass of the Sun) is more stressed, it will disintegrate.

The result is compressed into a singularity with infinite density and gravity.

Gravity warps space-time.

Become an event level.

Not even the light can escape. It was also heard that there is a black hole at the center of the Milky Way. I am a 6th grader.

Hope this knowledge is useful to you. 2009-05-23 19:40:42 Added: Why do you ask singularity? Now the singularity is not taken seriously.

In fact, from a professional point of view, the definition of a black hole is very clear, but the definition of a singularity is more complicated, which is actually a mathematical concept, not something that can be explained in one sentence.

However, the singularity mentioned by the general person Hashinai usually refers to the singularity inside the black hole, which is easier to explain.

When a star collapses into a black hole, a "horizon" is formed on the outside due to gravityThis horizon is actually a range, and all matter that enters the horizon, including light, can no longer escape. The entire area surrounded by the "horizon" is the region of the elimination of boredom, which is commonly referred to as a black hole.

But the collapse of the star is not completed after it collapses into the horizon. Objects that fall into the field of view do not stop when they enter the field of view. Under the tremendous gravitational pull, they will continue to fall towards the center of the black hole.

Eventually, the mass of the black hole itself will compress all the matter and mass in it to a point in the center of the middle of the bend, which is the singularity.

If two fiery liquid stars collide plastically, the high-temperature luminous material flow will gradually transition from an irregular ring to a perfect circle. And the center of the flow of matter must be empty, this existence of nothing, some people call it a black hole. The star is like a tire.

That's just a flow of matter! There's a lot of room at the edge. If something similar happens in the solar system, it may at least involve the radius of the Earth's orbit.

The flow of matter and the envelope means the flow of plasma, and the flow of plasma, which means the current, necessarily manifests itself as an energetic manifestation of angular momentum. That is, the axial particle flow representation. At the end of the day!

The so-called black hole is the diversionary vortex of the material cavity where the stars collide. There was nothing strange about hunting originally! It is a common astronomical phenomenon in the universe, but it is only novel because of the part of human vision and the possession of vision!

It can't prove that anyone is huge, and it can't get the back door of the universe. Science is science, and science cannot be absolute! This is the fact that astronomical phenomena are meant to inform people.

If it can be absolutely, it is still clear that the solar system is more objective, but unfortunately, even if the solar system is not clear, it is true that tens of millions of light years away!

It is neither a ball nor a hole, but it has the properties of a celestial body, such as angular momentum, mass, and also has the properties of a hole. In addition, the black hole is usually referred to as the singularity inside the black hole plus the space within the surrounding event horizon, which is not the Schwarzschild radius but the event horizon, because the Schwarzschild black hole is only the simplest theoretical black hole. You can think that the inside is empty, because the line will be sucked into the singularity, and you can also think that there are many things inside, because there is no falsification anyway, you can say whatever you want; It is also possible to think that there is no interior at all, because all the information about the black hole is revealed to the outside.

In short, astronomically, a black hole is a celestial body, and if we use an analogy, it is not impossible to think of a black hole as a hole. How does a speck of dust become a planet, then you have to ask the black hole, and if the black hole has an inlet, there must be an exit. Whether this exit is dust or a supernova, it's all karma.

The black hole is not a planet, it is a singularity in the universe and everything changes; According to the current black hole theory, there is a singularity with infinite density and mass at the center of the black hole, so the singularity must be defined before a black hole can be defined.

Quite possibly a planet. The interior of a black hole is highly attractive, and it may be related to slip and the recession of celestial bodies. The causes of black holes are very complex, but Laughnara only knew that the planet would die slowly.

I think it might be a singularity to grip him roughly; Because this singularity contains a large amount of black hole matter, and it has almost no big or small hand talk, the mass can be infinitely compressed, and the density can be as large as the stool touches.

It is not yet known exactly what a black hole is, because nothing can be observed. It's all the theory of scientists.

At the moment, it seems that the black hole should be a planet. Because a black hole is essentially a celestial body, it is not a hole as the name suggests, it is the "grave" of supermassive stars after they die.

And the center of the black hole is the singularity. The singularity itself has no physical strength, the gravitational force is infinite, the density and temperature are infinitely high, and it is a completely indescribable way of existence by the laws of human nature!

Normally, black holes do not only include the black hole planet itself, the part within the event horizon of the black hole is called the "black hole", that is, within the range of the so-called "Schwarzschild radius", the distance from the singularity to the event horizon is called the "Schwarzschild radius", the size of this radius is closely related to the mass of the black hole, the larger the mass, the larger the radius!

The theory of relativity and quantum mechanics are the two cornerstones of modern physics, but neither theory can explain what the inside of a black hole is, and it seems likely that humanity will never know what a black hole really is!

Because a black hole devours everything that comes close to it, including the information itself, it means that we can never directly access any information inside the black hole. We need a higher level of natural law to understand black holes and interpret black holes!

tomb". And the celestial bodies in the universe are basically planets, and black holes are no exception!

A black hole is a massive object, not a hole.

Black hole is the ultimate form of stellar evolution, which is a special celestial body formed by the gravitational collapse of the stellar nucleus when the massive star evolves to the end, the scale is infinitely small, the density is infinite, and the gravitational force is so strong that no matter (including light) can leave its surface. That is, only massive stars have the potential to evolve into black holes.

Black holes are a very massive thing that is difficult to peep into with our current technology.

Black holes are supposed to be a planet. Because a black hole is essentially a celestial body, it is not a hole as the name suggests, it is the "grave" of supermassive stars after they die.

I think it's a planet, but black holes are amazing, they devour everything that comes close, so we have to study it further.

Black holes are the most mysterious objects in the universe and the ultimate puzzle in astronomy, where the gravitational pull is so great that even light cannot escape within the radius of its event horizon, where all the laws of physics fail! If people can one day crack its secrets, all the problems in the universe will be solved!

A black hole is also essentially a celestial body, and the center of the black hole is the singularity. The singularity itself has no stamina.

I don't think it's easy to explain, but if I have to say it, it should be a singularity.

It's hard to say, but it's probably a celestial body.

I think this is really hard to define, but it depends on what the experts say.

A black hole is also essentially a celestial body, and the center of the black hole is the singularity.

Peter, the Standard Model from Einstein's Gr equation of general relativity shows that the singularity of a black hole has no dimension. I produce. It is a point.

Einstein himself was troubled by this, because it was clearly the result of a convergence effect.

Again, according to the GR, the big ** obviously starts from an infinitely small space that contains infinite energy. General relativity predicts that all the mass of a black hole is contained in an infinitesimal space.

Quantum mechanics does not allow particles to collapse beyond their minimum wavelength. Obviously, the ** about gr is ridiculous, and no one believes it anymore. However, by starving for the absence of a theory of quantum gravity, this model is still repeatedly taught and disgusted.

According to quantum mechanics qm, the singularity of a black hole is a ring, or volume in the shape of a doughnut, where what we call matter is torn apart into pure energy.

The image above shows the gravitational field of a rotating black hole, with the inner part showing the outer and inner event horizons.

The image below is another description of the singularity by Kip Thorne, a well-known black hole expert. I don't know what he meant by those terms.

All the information here, including the chart above, is based on the initial hypothetical QM calculations. Since this is the frontier of science, you should take it as the current level of understanding, or the current model, not the truth.

There are countless black holes in our universe, and each black hole may have its singularity, in the sense that the original singularity of the universe was much more massive than the singularity in the universe today. However, our universe is probably not alone, there may be other universes outside of our universe, even an infinite number of universes, and it is also very likely that there are more black holes than in our universe, so the singularity of the universe may also be many.

However, it must be noted that the above statements are only speculation, and for a long time to come, whether it is the singularity of black holes or the singularity of the universe, the perception of them can only be speculation.
