Research on black holes has come to an end, but decades have passed.

He Xi and Liang Bing, who represent the angel civilization, got a method of realizing light particle technology from it, while Yue Yuanzhou has a deeper understanding of it.

Although it has not reached the point of creating black hole war stars, the manufacturing of matter decompressors has been theoretically feasible.

Extracting something that falls into a black hole from a unidirectional membrane region without falling into a black hole, yes... it falls into a black hole without falling into it. The matter that truly transcends the inner horizon cannot be extracted because they are within ten thousandth of a second

Within, the time is infinitely close to the singularity.

Now the Infrastructure Number has left the black hole and is quietly advancing in the dark universe.

Hexi wants to return to the Angel Nebula, and the Angel civilization needs her, especially in this dark universe. Without her, Angel's technology would have almost made no progress, and Kaisha plans to continue looking for Yan in the Milky Way.

Kesha is very self-aware in scientific research. She knows that she can't help even if she returns. It's better to continue looking for Angel Yan in the Milky Way.

Liang Bing was a little strange, not saying that he would go back or that he would not go back.

At this time, Hexi seized the time to continue discussing the issue of black holes.

In fact, she was also very entangled. The discussion with the knowledgeable people made her feel very happy. So she didn't want to leave now, but she had to leave.

She faced Yue Yuanzhou and said: "Black hole evaporation theory shows that black hole evaporation will lead to information loss, but on the other hand, information conservation is based on the basic principles of quantum theory, that is, universal conclusions obtained by unity. This black hole information paradox

If it is not solved, it will continue to lay a time bomb for the entire theory."

The unitary nature she mentioned actually refers to the unitary operator. The unitary operator is a special operator, which is a bounded operator that retains the inner product in Hilbert space.

What she means is that if the information is not conserved, the entire set of unitary operators will be overturned.

"There is no problem with this. We believe that information is not conserved to the extent of a black hole, but it is conserved on the entire cosmic scale." Yue Yuanzhou answered directly.

At this time, the four of them had returned to the hall of the infrastructure number and sat next to a small square table, feeling like they were chatting about family matters.

Liang Bing looked careless and slapped melon seeds: "Why don't we do a black hole evaporation experiment?"

"There is nothing to do. We have already done experiments on this aspect."

"But..."

Seeing that Liang Bing was so entangled with this problem, Yue Yuanzhou simply said: "The black hole will evaporate, but the evaporation rate is proportional to the temperature, while the temperature of the black hole is inversely proportional to its mass."

"That is, the smaller the mass of a black hole, the higher the temperature and the faster the evaporation. The black holes we observe now are basically giants, so their evaporation is small and far less than the increase in their absorbed substances.

The mass of the universe. If you want to wait for a large black hole to evaporate, you will not be far from the silence of the universe."

Liang Bing stopped knocking the melon and thought for a while and said, "Isn't there still a small black hole? For example, the one just now was very small. We know that the evaporation of a black hole is formed by the pair of positive and negative electrons produced by vacuum decay, and when the black hole is

If the positive and negative electrons appear in pairs are sucked in, the black hole will reduce the mass of an electron because of the annihilation of positive and negative matter."

"And that electron will become a free electron and be ejected by the black hole in the form of a jet. In this way, the mass of this black hole will become smaller, and will not its surface area also become smaller? Why don't we put a lot of antimatter?

Throw it into the black hole and try it..."

Oh, it turns out that Liang Bing is thinking about this.

Yue Yuanzhou smiled and said, "You can also try this in the future with a small black hole."

Some things still need to be tried by angels themselves, and of course Shenzhou Civilization has tried them.

Black hole evaporation does not violate the area theorem.

Because when the mass of a black hole becomes smaller, its surface area will not decrease. Since the mass is proportional to gravity, the mass decreases and the gravity will also decrease. Therefore, the surface area of ​​a black hole actually increases.

The fate of black holes evaporate to the end does not disappear quietly, but as the mass decreases, the temperature increases, and the evaporation becomes more and more intense. After this process reaches a certain level, the black hole will explode violently

End.

So will this phenomenon contradict the concentration of black hole mass at all at the singularity?

It is logical that there is no mass outside the singularity of the black hole to its Schwarzsie radius, because the mass of the black hole is concentrated at the singularity.

And the black hole singularity to the inner horizon, that is, the radius r that has become the time axis. The entropy in this range, or time always points to the singularity, wouldn't it mean that nothing can come out at this point?

Isn’t it a contradiction to the reduction in the mass of a black hole?

This is true according to normal thinking, but that is just the normal thinking of human beings, and the mystery of the universe will not accommodate human thinking.

The universe exists objectively, and this is what is called the constant movement of heaven.

But this is not actually contradictory.

Because the solution of general relativity does not say whether the time direction of radius r points to the singularity or the inner horizon. We believe that pointing to the singularity is just because everything falls into it cannot come out, so we think so. The time direction is

Of course, the white hole solution is the one that points outward.

At the same time, the uncertainty principle tells us that it is impossible for you to know the position of a particle and its speed at the same time.

But in a black hole, its position is determined, that is, it is at the singularity. In this way, its speed becomes infinitely uncertain, and this infinite uncertainty gives it infinite possibilities.

So it even speeds away from the singularity, so the black hole mass evaporates and decreases.

It is said to disappear... because in the place where the singularity and r, space is no longer space, but time, so speed is meaningless.

The universe is so wonderful.

Liang Bing’s question can only show that the original basic science of the demon was not solid.

How can a god-level civilization that has not reached the level of modification of the rules of the universe violate the rules of the universe?

Yue Yuanzhou knew this well, so when he heard that the brain-computer combination in the spiritual cage world could accurately calculate the position and speed of particles, he was not too surprised.

If there is such a world, then this world must be the legendary Buddha's world, because the causes and consequences there have been determined, how sad it is to a world without variables.

Yue Yuanzhou got a lot of information about this black hole experiment. He also obtained a lot of relevant information about the concept of information, such as the dislocation of space-time and causality and inversion of cause and effect.

But some things do not have to be told to the collaborators, so he only answered part of Liang Bing's words.

"Let's go, fortunately you put the large insect bridge in the cantilever of the Orion, otherwise you will have to walk for a long time." Yue Yuanzhou looked at the star map and changed the topic quietly.

"That was released when Yan came. Unfortunately, Kaisha has been searching for that star field for so long but still has no trace of Yan." Hexi said immediately.

Yue Yuanzhou sighed when he heard this, but did not speak.

He had already helped find Angel Yan, but he really couldn't find it. Sometimes he felt a little sympathetic to Ge Xiaolun. Yan came to him across countless light years, but not only did he not see him, but he disappeared.
