In the process of constantly falling into the black hole, Li Li didn't feel any pull, nor did he feel the resistance, let alone the radiation, the radiation in the black hole was extremely great, even the god-level powerhouses were very influential, and the temperature inside the black hole was extremely high, even more than the stars.

I can't feel the drag and pull, because the process of falling a black hole is actually equivalent to a free fall on the earth, like a person jumping from a space station in low earth orbit, slowing down, if you don't consider the air, this person has no effect before touching the ground, and it is no different from usual.

The black hole is surrounded by a vacuum zone, there is no air, and there will be no friction, so Li Li did not completely fall to the point in the center of the black hole, he would not die, and the Schwarzschild radius of the black hole is not a wall, but an invisible space, an invisible boundary, for the observer it is the Schwarzschild radius, for you, there is no boundary.

Before he could react from the falling thoughts, Li Li had already fallen into the Schwarzschild radius of the black hole, and as soon as he fell into the Schwarzschild radius, a scene immediately surprised Li Li, what kind of world is in the Schwarzschild radius, no one knows, the gravitational attraction here is infinite, and even the light is bound in it.

"The Sun!" This was the first thought that came to Li Li's mind, because in the Schwarzschild radius, there was not a piece of darkness, but a piece of light, and there was a luminous point in the very center, this light source was as dazzling as the sun, but it had no volume, it was a point, a point that could ignore the size of the volume.

It's too incredible to imagine that there is a lot of light inside the black hole, and humans observe the black hole because they see a layer of light on the surface of the Schwarzschild radius of the black hole, but inside the Schwarzschild radius, it is pitch black, and this black is pure black.

But when you really enter the black hole, you find that there is a bright light inside, and there is a luminous point comparable to the sun in the middle, to be precise, it should be the light-absorbing point, that point is the body of the black hole, an infinitesimal, small point with no volume, if it were not for the absorption of light, Li Li probably would not have been able to discover the existence of this point.

This point, like a whirlpool center, absorbs all the light entering the Schwarzschild radius, and it is precisely because of this point that it constantly absorbs light, so we can see and feel its existence.

This point is very dazzling, people dare not look directly, if it were not for Li Li reaching the god level, I am afraid that the moment his eyes saw this point, his eyes would be blind directly because of the strong light, this point is too bright, tens of thousands of times more dazzling than watching a nuclear explosion up close.

Seeing this incomparably dazzling luminous point, Li Li knew that this was the culprit of creating a black hole, a singularity with infinite mass and infinitesimal volume, this singularity had distorted space to an incredible degree, at this point, any matter was crushed, even if a small spaceship made by strong interaction force could easily smash a planet and pass through the star, and the unscathed spaceship, at this point, still had to be crushed. This degree of spatial distortion, resulting in a terrifying gravitational pull, can crush any physical matter in the universe.

People who fall into a massive black hole will not be torn apart by the tidal force of the black hole during the fall, and even if they enter the Schwarzschild radius, they can still survive and fall to the center of the black hole - the singularity, and then they will summarize life.

However, the singularity is also the beginning of the black hole experience, this is a very terrifying point, the entire solar system, can be easily compressed by this point to infinitesimal size, even smaller than a quark, what is this concept? It's hard to imagine horror.

Again, this point is a magical point because it has no volume, in other words, it is not made up of elementary particle quarks, but pure energy.

As we all know, matter is made up of atoms and molecules, atoms are made up of nuclei and electrons, collide through accelerators, and the nuclei will produce two kinds of particles, protons and neutrons during the collision, so we know that atomic nuclei are made up of protons and neutrons.

Then we continue to accelerate the collision of protons and neutrons, or collisions with protons themselves, and after countless collisions, we find that protons and neutrons still break apart and are smashed into quarks.

This quark is the smallest particle, because no matter how you collide with the quark, you can't hit the quark, so we think that the quark is the elementary particle, and the so-called elementary particle is the most basic particle that constitutes matter. (There may be particles smaller than quarks, but current human technology, even predicts, makes it almost impossible to smash quarks, so this one uses quarks as the elementary particle.) ）

The center of the black hole - the singularity, is just a point, infinitesimally small in size, and can even be ignored, as for how small this point is, I am afraid it is smaller than a quark, so that the contradiction appears, since the singularity is so small, where does the matter swallowed by the black hole go?

And the mass of this black hole is very large, 4.5 million times that of the sun, and the sun is tens of millions of times that of the earth, in other words, the mass of this black hole is many times that of the earth, and it can no longer be calculated in billions, but in megabytes.

We know that any object on earth, even steel, if magnified countless times, will find countless voids in it, and if there is enough pressure, it can compress a tank to the size of a fingernail, so that the gaps inside disappear.

If the pressure is large, it can not only eliminate the gap between the iron atom and the iron atom, but even compress the electrons moving around the nucleus into the nucleus, so that the nucleus of the iron atom and the nucleus are closely connected together, which is the strong interaction force.

Further compression, then it is likely that the nucleus is fragmented, then the protons or neutrons are tightly connected, and the compression volume is further reduced.

Even if Mount Everest is compressed to this point, the volume is probably not the size of a baby's fingernail, and you can imagine how dense it is, more than countless times the density of white dwarfs.

Quarks are tightly connected to each other, which is the smallest point at which an object can be compressed, because quarks are already elementary particles and cannot be divided, and the object retains this volume even with force.

Then the contradiction is obvious, since the black hole distorts space and produces a terrifying gravitational pull, this gravitational force can tear everything apart, compress everything, and even the solar system can be compressed into a point by it. The problem is that the entire sun, even if it is compressed by the gravitational pull of infinity, completely becomes quarks, and these quarks accumulate and can be seen by the naked eye, after all, the sun is ten million times the weight of the earth.

But in fact, even if a hundred suns enter a black hole and are compressed by the black hole's gravity, the volume is the same, they are all infinitesimal, so small that there is no volume, that is, compressing one sun, and compressing 10,000 suns, the effect is the same, both are infinitesimal volumes.

There are countless black holes in the universe, black holes also have sizes, the largest black hole is larger than the Milky Way, the smallest black hole is probably not the size of a fingernail, we define the size of the black hole, not that we see the black hole itself, not the size of the black hole center singularity, just by the Schwarzschild radius generated by the singularity to distinguish the size of the black hole, in fact, the size of all black holes, the size of the singularity, is the same, they are infinitesimally small, there is no volume at all.

The largest black hole in the universe, its Schwarzschild radius exceeds the Milky Way, then the mass of this black hole is probably countless times the mass of the Milky Way, and similarly, this black hole singularity is as big as Sagittarius A, so any matter that enters the black hole, no matter how much and no matter how large, will disappear and become volumeless.

But it doesn't really disappear, because only the volume disappears, but the mass doesn't disappear, so where does the volume of these substances go, even if it is compressed to quarks, there will still be volumes, because quarks are elementary particles, indivisible particles.

For this result, Li Li understood by searching the memory of the mysterious old man that any object that entered the singularity was completely and completely torn apart, and this shredding was not only macroscopic, but also microscopic, just like at this moment when Li Li was close to the singularity, his Nirvana true body would be torn apart and molecularized, and the carbon, hydroxide and oxygen molecules that constituted carbon-based life would be torn apart again, turning into neutrons and protons, and continuing to be torn apart, completely turning into quarks.

At this time, Li Li has been completely quarked, and this is not over, the quark has been torn apart and become energy, yes energy, pure energy.

Matter and energy make up the universe, mass and energy can be converted, for the indivisible elementary particle quark, if one day, human science and technology progress again, can divide the quark, then a surprising scene will appear, smashing the quark, not to produce new matter, but energy.

When a quark is shattered, it is energy, in other words, a quark is the smallest particle that is made up of energy and can no longer be divided.

In this way, it can be very logical to explain where the matter that enters the black hole goes, and it also explains that the black hole singularity, infinitesimite, infinitely mass, no matter how small the quark is, also has volume, and the singularity does not, because the singularity is the energy composition that is compressed to the limit, and the energy has no volume, but it can produce gravity.

Mass and energy, like the front and back of a coin, this coin is the universe, the unit of energy in addition to joules, there is also mass energy, large objects can distort space, produce gravity, large energy aggregates can also distort space, produce gravity.

(About the black hole singularity is a large energy aggregate, is Shuangmu's inference, about the black hole inference, Shuangmu has seen more than a dozen, but each one, Shuangmu can find loopholes, even the most mainstream white hole theory, Shuangmu can also find countless loopholes, so the energy argument, Shuangmu thinks it is the most appropriate, of course, it may not be completely correct, maybe which god who reads the book will find the loophole, but please forgive Shuangmu's ignorance, after all, Shuangmu is just a hobby of physics, not astrophysics.)

And this argument and the dimension argument form a system, of course, everyone finds loopholes, please forgive me, the dimension is too mysterious, and we can only rely on leapfrog thinking and divergent thinking. ）
