you come from the sky

But look around you - death and light are always everywhere.They begin, end, accompany, and restrain each other. They enter the nameless dream, attach to that dream, and burn words in the cycle of reincarnation, perhaps just to create a little bit of beauty.

—Roger Zelazny, The Light King

44 Nameless Dreamland

Bian Yu took a deep breath and closed his eyes.

He was walking on an ice field, and when he walked forward, he also took a step in all directions. When he turned around, he saw himself with his back turned to him.There are countless eyes in that sky, they have no eyelids, but they can blink.Bian Yu raised his head, a white snowflake fell on his face, and he heard a voice——

"Why did you come here?"

Bian Yu turned his head to look, it was Fang Haochen, standing next to Bian Yu unscathed, looking like a phantom belonging to an illusion.

This is indeed an illusion, an illusion created by Bian Yu using Fang Haochen's dream.

Bian Yu replied: "This is the end of time, I want to come and stay for a while."

Fang Haochen raised his head, as if he knew Bian Yu's current situation very well, so he asked, "You still don't know the secret of 201, do you?"

"..." Bian Yu nodded, "What I don't know is not just the answer, I don't even know the question." He wants to reveal the truth of the secret of 201, but for him now, even the secret of 201 itself is Do not know at all.

As Bian Yu said, he plucked an eye from the sky, and that eye grew wildly on the ground, and finally became taller and bigger than a human.Bian Yu touched the lidless eye, and the pupil turned into a door.

"Are you coming?" Bian Yu asked as he opened the door.

"Of course." Fang Haochen said.

On the other side of the door is a place Bian Yu is very familiar with - the teaching building of the Institute of Mathematics, Chinese Academy of Sciences. He and Fang Haochen stood there, watching "Fang Haochen" in this scene quickly catching up with "Bian Yu" , this is an extremely common time among Fang Haochen's countless entanglements with Bian Yu in the Chinese Academy of Sciences.

["Bian Yu, Director Lu's project 'A Mathematical Model Solution for the Influence of Electromagnetic Fluid on the Exploration of the Internal Structure of the Human Brain', did you take the lead in the phased results?"

Bian Yu glanced at Fang Haochen, tilted his head and replied mysteriously: "I won't tell you."

"Why didn't you tell me?" Fang Haochen was puzzled, and he quickly caught up with Lian Yu, "This staged research is very valuable..."

Speaking of this, Fang Haochen seemed to have thought of something, he paused, and replied very solemnly: "Dr. Bian, don't worry, I represent 201, and I swear that I will never steal your research results, nor will I reveal your secrets." data."

"It's because you represent 201 that I didn't tell you." Bian Yu said with a smile, "I didn't tell you that you pestered me so much. If I told you, would you stop clinging to me every day?"]

"You were too much back then." Fang Haochen glanced at Bian Yu and complained.

"Really?" Bian Yu smiled happily, "I thought you were cute back then."

Fang Haochen glared at Bian Yu, but Bian Yu didn't mind, he graciously took Fang Haochen's hand and took him to watch the scene.

"I have never understood one thing." Bian Yu said, "When you were at the Chinese Academy of Sciences, you told me that the research direction of 201 was about the unified field, but Lu Yongan's research topic had nothing to do with the unified field. Why did 201 do this? Interested in the subject, and even specially sent you to recruit Lu Yongan into 201?"

Fang Haochen didn't answer, another eye fell from the sky, Bian Yu opened the door in the eye, and dragged Fang Haochen to the next place: 201.

To be precise, it is the movie theater in the 201 Training Center.

Bian Yu and Fang Haochen sat in the center of the theater, and a movie featuring them as the main characters was playing on it.

The first scene is in Bian Yu's dormitory, "Fang Haochen" is holding Bian Yu's thesis, and the two confront each other.

"Fang Haochen" on the screen recited sonorously——

["So the author intends to simulate the structure of the human brain through a mathematical model to build a superintelligence, and through superintelligence to realize... the cognition of the unified field."

"You have studied the unified field."

"You have studied why the unified field rejected our project? Why did you refuse to join 201?"]

"I don't like this part." Bian Yu frowned and raised his hand, waving to the projection hall, and the projectionist quickly cut this part.

"I like it very much." Fang Haochen, who was sitting beside him, imitated the way Bian Yu teased him just now, and said, "This is the beginning of my understanding of you."

"And your thesis is very important. Dean Cheng borrowed it as soon as I took it back."

"I know." Bian Yu replied.

"At the beginning, I thought 201 was interested in the mathematical tools used in this topic. But now, it is not. Director Lu's research topic is 'human brain structure', and my thesis is about 'human brain-superintelligence- Unified field', what they have in common is not 'unified field', but 'human brain'..."

Bian Yu paused for a moment before saying, "201 may not be interested in the research tools used in the subject, but what 201 is interested in may be Lu Yongan's research subject itself—the internal structure of the human brain."

Fang Haochen looked at Bian Yu and smiled, but he didn't speak, the movie soon reached the second scene, on the balcony of Bian Yu's dormitory, "Fang Haochen" and "Bian Yu" were huddled together.

【"You guessed right. 201 is indeed not conducting pure theoretical research on the unified field. In other words, 201 used to focus on the unified field, but it is no longer the case."

"The current 201 is actually researching a kind of energy. The generation of this energy is similar to nuclear fusion, but it does not require ultra-high temperature induction and does not release a lot of heat. But its destructive power is amazing, and it will only release With a small amount of gamma rays, there are no radiation and pollution problems, and the application prospects are very broad.”]

The movie was going to be played again, but Bian Yu suddenly stood up: "You don't need to watch it anymore."

"Why didn't I think of it earlier."

"You told me at this time that what 201 is studying now is not the unified field." Bian Yu lowered his head and said to himself, "The unified field is indeed the research goal of 201, but for the current 201 , the research on the unified field is just a cover. The only person who is really researching the secret of 201 is Dean Cheng. What he pays attention to is what else is discovered by 201 in the process of researching the unified field. The secret of 201 is not Unified Field, but what it finds."

That explosion, that explosion in the old base.

The scene of the movie theater melted quickly, and the surroundings turned into the appearance of the old base. Under the dim candlelight, the machines kept ticking, and the "Bian Yu" in the scene was translating the Morse code for "Fang Haochen". At that time, they didn't know what kind of thrilling things they would translate.

"I don't understand this place either." Bian Yu said to Fang Haochen, "I can't understand why a poem emerges from the black hole. Could it be that the black hole has consciousness? Why is there only one poem left? Part of it, but you know the whole of the poem, is there really a 'telepathy' that cannot be explained by science?"

When Bian Yu said this, he suddenly froze. He seemed to be grasping something in the dark, black holes...consciousness...brain structure...all of these were like pearls scattered on a plate, only missing one thread, one The thread that can thread them together.

He wants to find something... Bian Yu has a very strong intuition, he is very close to the answer, but he can't grasp it no matter what, the answer is like a thread floating in the universe, he As soon as he stretched out his hand, the gossamer flew away.

"Bian Yu," Fang Haochen called Bian Yu's name at this moment, "I'll take you to a place too."

Bian Yu stared blankly at Fang Haochen, nodded, Fang Haochen lowered his head and smiled, an eye fell from the sky, Fang Haochen opened the door, and took Bian Yu to the next place.

The health center in 201 is where they were resettled after returning from the old base.

"Fang Haochen" over there ran to "Bian Yu" out of breath, and asked "Bian Yu" stupidly if he wanted to go to the movies together, and then blamed himself for preventing Bian Yu from leaving 201.

Bian Yu always dislikes Fang Haochen's discomfort.

In order to comfort "Fang Haochen", "Bian Yu" said that it would be the same to give him another chance, everything is predestined.

"Fang Haochen" muttered: "If according to what you said, people do not have free will, then there is no difference between liking and disease."

That's where the scene stops.

Fang Haochen who was beside him turned around and looked into Bian Yu's eyes. There was infinite appreciation and love in his eyes, and he asked him: "Bian Yu, do you want to be with me?"

Bian Yu lowered his eyes, afraid to look at Fang Haochen for a moment, but he knew the answer, no matter how many times he decided not to pursue Fang Haochen, it would not change.

"Think." Bian Yu replied.

Fang Haochen was not timid, he still took Bian Yu's hand and asked: "Then do you want to be with me because of 'sickness' or because of 'love'?"

Bian Yu replied without thinking, "Of course it's because of 'love'."

Fang Haochen smiled: "So you think people have free will."

Bian Yu was stunned.

Free will?

indeed.

If the particles in the human brain do not have quantum motion, then every particle can be observed and measured. There is a Laplace demon in the human brain, and all the decisions made by "I" will be in the "I" "If the decision is predicted before, then there is no difference between "love" and "sickness". The attraction between people is the mission of reproduction and the choice of biological evolution.

However, if the particles in the human brain have quantum motion, and the motion of each quantum cannot be observed and predicted, and the decision made by "I" is based on the decision itself, "love" and "disease" are different.

Fang Haochen raised his voice and asked again: "Bian Yu, do you love me because of 'sickness'?"

Bian Yu shook his head, and replied very solemnly and seriously: "No, I love you only because I love you."

"Science can prove it for me."

"What we are understanding now is a theory that cannot be verified?" Bian Yu said, "More than that, special relativity, general relativity, and many theories that have not been verified by experiments can be understood by humans."

Bian Yu continued: "Gödel's incompleteness theorem says that in a system of axioms, there must be truths that cannot be proved. But humans can understand truths that cannot be proved, so human consciousness can go beyond axioms... This originates from the collapse of the wave function in the brain, so... human consciousness is determined by quantum mechanics."

Man has free will.

He loves Fang Haochen, not because he is a natural homosexual, but because of love, because of the love he chose.

Thinking of this, Bian Yu's heart was beating violently.

He solved it, all the problems were solved at this time, the darkness dissipated, and only him and Fang Haochen were left between the heaven and the earth.

Bian Yu's whole body was trembling, on the ice field, under the snowflakes made of strings all over the sky, he hugged Fang Haochen tightly, hugging the person he loved with all his heart.

Thank you, Fang Haochen, and thank you for loving you so much. This love made me find the answer.

He found the key of 201 and opened the lock of 201.

Note:

At the beginning of this chapter, it can be understood that Bian Yu made such a description in his "MindPalace" in order to avoid simply talking about the theory too boring, although in the end he behaved a bit like the schizophrenic scientist (doge) in "Battlestar Galactica"

Also because it is in the "consciousness scene", Bian Yu hesitates when Fang Haochen asks him if he loves him, Bian Yu thinks this is the "Fang Haochen who loves him" he imagined.

Gödel's incompleteness theorem was proposed by the Austrian-American mathematician Gödel in 1931, which is known as one of the three major achievements of modern logic science in philosophy (the other two are Tarski's truth theory and Turing machine decision problem), Gödel proved that any formal system, as long as it includes a simple elementary number theory description and is self-consistent, must contain some propositions that cannot be proved true or falsified by the methods allowed in the system.That is to say, "true" and "provable" are two concepts. What is provable must be true, but truth is not necessarily provable.

In addition, regarding the part of self-awareness, although there are quantum activities in the human brain, it is still difficult to prove that people have self-awareness, because in the process of microscopic matter to macroscopic structure, decoherence occurs and becomes deterministic.At present, most scholars in the academic circle believe that human free will is limited.
