Three body 2- Dark Forest
It has been more than a year since the last "Three-body" was published. Over the past year, I have read a lot of books on business, literature and trends, cultivated the habit of listening to books, and updated my reading style, quickly selected books, skimmed ordinary books and * * * accurate books. Combined with my experience and experience this year, I have deepened my understanding of this book and shared with you the highlights of the second part.

When the three-body crisis appeared, escapism followed. The main argument is that it is meaningless to plan the defense of the earth and solar system after four and a half centuries on the premise that the cutting-edge science of mankind has been strangled by dysprosium. Considering the height that human science and technology can reach in the next four centuries or more, a more realistic goal should be to build starships so that a small number of human beings can escape to outer space to avoid the complete extinction of human civilization.

There are three options for the escape destination:

First, the choice of a new world, that is, to find a new world in which human beings can survive among the stars. This is undoubtedly the most ideal goal, but it requires extremely high sailing speed and long voyage, which is unlikely to be achieved from the technical height that human beings can achieve in the crisis stage.

The second is the choice of starship civilization, that is, fleeing humans regard the spaceship as their permanent residence, so that human civilization can continue in the eternal voyage. This choice is faced with the same difficulties as the new world choice, but more emphasis is placed on the technology of establishing a small self-circulating ecosystem, which far exceeds the current technical ability of mankind. The biggest obstacle to escape is not the dispute between countries. ""it's a dispute between people, that is, who goes and who stays. "

Who goes and who stays involves the basic values of human beings. These values have promoted the progress of human society in the past, but they are a trap in the face of this ultimate disaster. Up to now, even most human beings have not realized how deep this trap is.

Third, choose to avoid temporarily. After the Three-body Civilization settled in the solar system, people who fled to outer space actively communicated with the Three-body Society, waiting for and promoting the relaxation of its foreign policy on the residual human beings in outer space, and finally returned to the solar system to live with the Three-body Civilization in a smaller scope. The temporary avoidance option is considered to be the most realistic scheme, but there are too many variables.

Shortly after the emergence of escapism, there were many media reports around the world: the United States and Russia, two space technology powers, have secretly started their own escape plans from outer space. Although both governments immediately and categorically denied the existence of this plan, it still caused an uproar in the international community and triggered a "technology privatization" movement. At the third special session of the United Nations General Assembly, many developing countries demanded that the technologies of China, Russian, Japanese, China and European Union be made public, and all advanced technologies, including space technology, be provided to the international community free of charge, so that all countries and nations of mankind can enjoy equal opportunities in the face of the three-body crisis. Advocates of the "technology publicity" movement also cited a precedent: at the beginning of this century, several major European pharmaceutical companies charged African countries with high technology patent fees for producing the most advanced AIDS drugs, which triggered a lawsuit that attracted much attention. Faced with the grim situation of the rapid spread of AIDS in Africa, under the strong pressure of public opinion, several major pharmaceutical companies announced that they would give up their patent rights before the trial. Facing the ultimate crisis facing the world at present, opening technology is the unshirkable responsibility of all mankind in advanced countries. The movement of "technology nationalization" has received unanimous response from developing countries and even the support of some EU member States, but the relevant proposal was rejected at the meeting of the United Nations Planetary Defense Council. Since then, China and Russia put forward a proposal of "limited technology privatization" at the fifth special session of the UN General Assembly, proposing technology privatization among the permanent members of the Planetary Defense Council, which was immediately rejected by the United States and Britain. The U.S. government says it is unrealistic and naive to make technology public in any form, even under the current circumstances. The national security of the United States is still in an important position "second only to earth defense".

The failure of the proposal that "limited technology is public" also caused the division among technological powers, which led to the bankruptcy of the plan to establish the joint fleet of the earth.

The frustration of the "nationalization of technology" movement has a far-reaching impact, which makes people realize that even in the face of the devastating three-body crisis, human harmony is still a distant dream.

Escapism triggered the "technology nationalization" movement. Only when the international community has a real understanding of escapism can it partially bridge the gap between developed and developing countries and between developed countries.

"On the occasion of the three-body crisis, the former permanent members of the Security Council held urgent consultations and put forward the preliminary idea of the side wall plan.

"All countries have noticed the fact that after the appearance of Naoko in the first two times, more and more evidence shows that more Naoko are constantly reaching the solar system and entering the earth, and this process continues. Therefore, the earth is now a completely transparent world for the enemy. For them, everything in this world can be read at any time like an open book, and human beings have no secrets.

"At present, the mainstream defense plan launched by the international community, whether it is the overall strategic thinking or the smallest technical and military details, is completely exposed in the enemy's field of vision. Naoko's eyes are everywhere in all conference rooms, all filing cabinets, all computer hard drives and memories. A plan, a scheme, a deployment, no matter how big or small, will also be displayed in the enemy high command four light years away when they appear on the earth. Any form of communication within human beings will lead to leaks.

"What we should pay attention to is that the level of strategy and tactics is not directly proportional to technological progress. It has been proved by definite data that the three people communicate directly with transparent thinking, which makes them very incompetent in deception, disguise and deception, and it also gives human civilization a huge advantage over the enemy, and we must not lose this advantage. Therefore, the founder of the side wall plan believes that besides the mainstream defense plan, several other strategic plans should be carried out in parallel, which are opaque and secret to the enemy. At first, many schemes were envisaged, but it was finally determined that only the side wall scheme was feasible.

"What I said before should be corrected: so far, human beings still have secrets, and our secret is the inner world of each of us. Naoko can understand human language and read printed words and information stored in various computer media at high speed, but they can't read people's minds. Therefore, as long as we don't communicate with the outside world, everyone is an eternal secret to Naoko, which is the basis of the face-to-face teaching project.

"The core of the side wall plan is to select a group of strategic plan makers and leaders. They rely entirely on their own thinking to make strategic plans and do not communicate with the outside world in any form. The real strategic thinking, the completed steps and the ultimate goal of the plan are just hidden in their brains. We call them side wall people. The name of this ancient oriental meditator well reflects their work characteristics. In the process of leading the implementation of these strategic plans, the thoughts and behaviors shown by those who face the wall should be completely illusory and carefully disguised, misled and deceived. What the bystanders want to mislead and deceive is the whole world, including the enemy and their own side, and finally build a confusing maze of illusions, so that the enemy will lose the correct judgment in this maze and delay the time to judge our true strategic intentions as much as possible.

"The defenders will be granted high power, so that they can assemble and use some of the existing war resources of the earth. In the process of implementing the strategic plan, an outsider does not have to explain his actions and orders, no matter how incomprehensible such actions are. The behavior of those who face the wall will be supervised and controlled by the United Nations Planetary Defense Council, which is the only institution that has the right to finally veto the instructions of those who face the wall according to the United Nations Face the Wall Act.

"In order to ensure the continuity of the side wall plan, all side wall users will use hibernation technology to travel through time and reach the decisive battle era. During this period, when and under what circumstances they will wake up, and how long each time they wake up, it is up to the side wall users themselves. In the next four centuries, the United Nations Face-to-Face Law will exist as an international law and have the same status as the Charter of the United Nations. Coupled with the corresponding laws formulated by various countries, it will ensure the implementation of the face-to-face strategic plan.

The Committee's possible doubts about those who face the wall mainly lie in the following two aspects: the amount of resources used exceeds the set range, or people's lives are harmed. In addition, any doubt goes against the basic spirit of the plan.

However, the side wall plan was not as smooth as expected, and the three-body man also made a corresponding wall-breaking plan for the side wall plan of the earth people.

One by one, three broken-wall people were exposed by three-body broken-wall people. Will the earth really face destruction?

Does the extreme thought of "three faces" also reflect human fear of the three-body world, and abandon and doubt human technology and humanity?

"The first man facing the wall: frederick taylor." (Destroy mankind)

You have to destroy the earth's space army and make their quantum ghosts resist the three-body fleet. You think they are invincible, because the destroyed fleet can no longer be destroyed and the dead can no longer die. "

At the cost of his life, he really made himself jump out of the strange circle of the side wall, but the international community's doubts about the side wall plan are also rising, and public opinion demands further restrictions on the power of the side wall. However, from the nature of the plan, too many power restrictions will inevitably make it difficult for the strategic deception of those who face the wall, and the whole plan will lose its meaning. Face-to-face signing plan is a brand-new leadership system that human society has never experienced, and it can only be gradually adjusted and adapted. The hibernation of two face-to-face people undoubtedly provides a buffer period for this adjustment and adaptation.

"The second facial walker: Mannur Rediaz." (Man and the three-body world perish together)

By studying the atmosphere of three-body stars, they speculated that the atmosphere was produced by the previous planetary fall, and the falling planet broke the outer shell of the star, causing the internal stellar material to be ejected into space, forming the surrounding atmosphere. Because the motion of the three-body star is completely irregular, it is possible for the three stars to stagger at close range. At this time, the atmosphere of one star will be dispersed by the gravity of another star, but it will be supplemented by the eruption on the surface of the star. This eruption is not constant, like a volcano, it sometimes erupts suddenly, which is the reason why the atmosphere of the three-body star is shrinking and expanding.

By detonating a number of star hydrogen bombs deployed on Mercury, a chain reaction was triggered, which eventually brought the solar system into crisis.

"For the three-body world, before their planet was swallowed up by three stars, the solar system was the only hope, and no second world could immigrate in time. In this way, after human beings, the three-body civilization will also be completely destroyed.

"This is your mutually assured destruction strategy. When everything is ready and all the hydrogen bombs are in place on Mercury, you will use this to blackmail the three-body world and finally let mankind win.

This is a plan to swallow elephants with snakes. Humans cannot make such a large number of stellar hydrogen bombs. Even if the industrial resources of the earth are all exhausted, it may not be able to produce one tenth. Even a hydrogen bomb with a million stars is not enough to slow down the fall of mercury into the sun.

"The third man facing the wall: Bill Sheehan." (Controlling the human mind)

In the brain neural network, we found the mechanism of thinking to make judgments, and can have a decisive influence on it. Compare the process of human thinking with a computer: input data from the outside, calculate, and finally give the results. We can now omit the calculation process and give the results directly. When some information enters the brain, we can make the brain make a judgment without thinking and believe that this information is true by exerting influence on a certain part of the neural network. "

Shane's coping strategy-ideological seal,

Members of the Planetary Defense Committee unanimously oppose this method, believing that human mind is out of control, which is not essentially different from the destruction of this world.

But Shane, he said

"I think everyone has heard the story: a little boy's leg was pinned down by a fallen tree in the forest farm. He was the only one, and his leg was bleeding. If this continues, he will bleed to death, but he made a decision that made all delegates feel ashamed: pick up the saw, cut off the pinned leg, climb the bus to find the hospital, and saved his life. "

? "The question facing mankind now is to be or not to be, to be or not to be the whole race and civilization. In this case, how can you not give up something? "

After some weighing, Shane suggested that the government should not interfere too much to make people accept this thing voluntarily, and his claim was limited to one belief, that is, the victory of the war. Anyone who is willing to acquire this belief with the help of the ideological seal can use this facility completely voluntarily. Of course, all this should be carried out under strict supervision. "

In the concrete operation of ideological seal, in order to embody the principle of voluntariness, the operation is completed by volunteers themselves. He will open the book of faith by himself, and then press the start button of the ideological seal by himself. Before the actual operation, the system will give you three confirmation opportunities. Before each action, the letter of belief must be checked and confirmed by a ten-member team, which is composed of permanent members of the UN Human Rights Commission and special members of the Planetary Defense Council. In the whole operation process of the thought seal, the ten-member team was also present for strict supervision.

Because the demolition plan was pushed down one by one, the first person who demolished the wall could not bear the pressure of public opinion and committed suicide, which also verified the correctness of the demolition person from the side. Compared with the people on the other side of the wall, the Planetary Defense Committee had to take action. They "kidnapped" Luo Ji's wife, Zhuang Yan, hoping that Luo Ji would do something for the purpose of protecting his wife and really consider the safety of the people on earth.

Luo Ji was told that the three-person was most afraid of himself, and then linked to the previous car accident, Luo Ji gradually thought that he had met Ye nine years ago. At that time, the wisdom of the Santi was not developed, only knowing that they had met, but the specific content of the Santi was unknown, hoping to kill Luo Ji, thus eliminating the "time bomb" and removing the threat to the Santi world.

Recalling Ye Yu's conversation,

And two important concepts:

Luo Ji thought it over and over again, and suddenly realized. Can the "approximate" position of the three-body be exposed to other planets by sending the coordinate position of the three-body to the Milky Way, so that the three-body can be made public by the world and attract the power of other worlds to destroy or occupy the three-body world?

Luo Ji therefore thought about the coordinates of a star system launched in the universe, and predicted that this star system would change after 100 years.

Then Luo Ji went into hibernation.

Because of the excessive consumption in the wall plan, people's living standards have returned to the state of 1 centuries ago. Faced with the problem of food and clothing, people have no time to consider the matter of three-body destroying the earth. But after solving the problem (the rapid progress of human science and technology), they declared the world into a state of war and began to build a space fleet. But this time, unlike the past, all countries have clearly stipulated in their constitutions that the resources consumed by the space strategic plan should be limited to a certain range and cannot have a disastrous impact on the world economy and social life.

? "Later, someone would like to open, more and more people would like to open, all doubt that even for the victory of the doomsday war, it is worth paying so much. Think about it, which is more important, a starving child in your arms or the continuation of human civilization? You may say the latter is important now, but you won't think so when you put it there. No matter what the future holds, the present day is the most important. Of course, at that time, this idea was a big violation, a typical traitor thought, but more and more people thought so, and soon the whole world thought so. At that time, a popular slogan later became a famous historical saying ... "

"After about half a century of peace. The world is reminded of the three-body invasion again, and feels that war should be considered. Besides, human strength is not as low as before.

Then he declared that the world was at war and began to form a space fleet. But this time, unlike the past, all countries have clearly stipulated in their constitutions that the resources consumed by the space strategic plan should be limited to a certain range and cannot have a disastrous impact on the world economy and social life. It was during this period that the space fleet became an independent country ... "

After Luo Ji broadcast the coordinates of the stars to the outside world, Santi realized that it was necessary to block the broadcasting ability of the earth and immediately sent "water drops" to the earth.

180 years later, a small water drop detector arrived in the solar system. Although basic physics has not progressed, applied technology has developed rapidly.

After all the fleets were dispatched to intercept the "water drop" fiasco, people found that the star system logically introduced by 180 years ago had been destroyed, so they quickly woke him up and named him the savior.

What's it to you to destroy you?

An ordinary detector of the three-body fleet makes the earth fleet completely annihilated as easy as blowing off dust, and there is no room for changing hands. At this time, the earth people know how small they are compared with the three-body world. With the infrastructure locked, they can no longer make breakthrough progress on the basis of the original development. This unspeakable fear enveloped the earth in darkness.

After being completely defeated by water droplets, the human world is now divided into three internationals: the ancient earth international, the fleet international in the new era, and the starship international flying to the depths of the universe. There were only more than 5,000 people in the last international conference, but it carried all the hopes of human civilization.

When discussing the problem of starship earth's leading bodies at all levels, Zhang Beihai decisively put forward that "survival alone cannot guarantee survival, and development is the best guarantee for survival. During the voyage, we should develop our own technology and expand the fleet size. Facts in the Middle Ages and the Grand Canyon have proved that autocracy is the biggest obstacle to human development. Starship Earth needs active new ideas and creativity, and this can only be achieved by establishing a society that fully respects human nature and freedom. "

Because Starship International's flight in the Milky Way needs a lot of energy, it can't transport so many passengers to fly in it, so there are problems about which personnel should be retained to continue flying, and whether to use infrasound hydrogen bomb, a space nuclear weapon, to attack spacecraft targets that are well shielded from conventional radiation, which can produce multiple nuclear explosions in the air at infrasound frequency continuously, and generate strong electromagnetic radiation every time. Electromagnetic radiation interacts with the metal shell of the target spacecraft, converting electromagnetic energy into acoustic energy of the air inside the spacecraft, generating super infrasound waves, killing all macro-life inside the spacecraft, but basically not damaging the flight facilities.

Because infrasound hydrogen bomb is killed by electromagnetic pulse, it doesn't need to hit the target directly, but it can kill people inside the target by exploding at a considerable distance from the target. Radar stealth missiles can only be found by other detection means, including visible light observation, when they are close to the target.

Of course, the three of us can, but do we have the right to make this choice for the two thousand people on "natural selection"?

At this point, three people are standing on the sharp blade, being cut painfully, jumping to either side of the blade is falling into the bottomless abyss, which is the pain before the birth of new human beings in space.

Two axioms of cosmic civilization:

First, survival is the first need of civilization.

2. Civilization keeps growing, but the total amount of matter in the universe remains unchanged. "

"Don't go on like this, now the whole universe is a life-and-death situation! As Shane said, civilization probably sprouted in the universe billions of years ago. Judging from the current signs, the universe may already be crowded. No one knows how many empty places and unoccupied resources there are in the Milky Way and the whole universe. "

"There are two concepts that need to be defined: goodwill and malice between civilizations. Words such as good and evil are not rigorous in science, so their meanings need to be limited: goodwill means not actively attacking and destroying other civilizations, while malice is the opposite. "

"There are various degrees of exposure: the strongest exposure is to let me know your precise coordinates in interstellar space, and the second is to let me know your general direction. The weakest exposure only lets me know your existence in the universe. But even the slightest exposure may make me search and find you. Since you can find my existence, of course I may find you. From the perspective of technological development, it is only a matter of time. "

If you think I am kind, this is not the reason why you feel safe, because according to the first axiom, a kind civilization cannot think of other civilizations as kind in advance, so you don't know what I think of you, and you don't know whether I think you are kind or malicious; Furthermore, even if you know that I imagine you as kind, I know that you imagine me as kind, but I don't know what you think of me. What you think of me is quite roundabout, isn't it? This is the third level, and this logic can go on forever. "

? "This is the chain of doubt. There is no such thing on earth. Humans have the same species, similar cultures, interdependent ecosystems and close distances. In such an environment, the chain of suspicion can only extend for one or two layers, which will be dispelled by communication. But in space, the chain of doubt may extend very long. Before it was dispersed by communication, something like a dark war had already happened. "

"That is to say, whether you and I are a well-meaning civilization or a malicious civilization, the result is the same?"

"Yes, this is the most important feature of the chain of suspicion: it has nothing to do with the social form and moral orientation of civilization itself. Just regard every civilization as a point at both ends of the chain, no matter whether it is good or bad, it will become the same thing after entering the network formed by the chain of suspicion. "

"But if you are much weaker than me, there is no threat to me, so I can always communicate with you?"

"No, this will introduce the second important concept: technological explosion. She doesn't have time to explain the concept, but it's much easier to speculate than the chain of suspicion. Human civilization has a history of 5000 years, and the life history of the earth has several billion years. However, modern technology has developed for 300 years. From the time scale of the universe, this is not development at all, but explosion! The possibility of technological leap is the explosive buried in every civilization. If it is ignited by internal or external factors, it will explode with a bang! The earth is 300 years old, but there is no reason to think that human beings are the fastest growing civilization in the universe, and the technological explosion of other civilizations may be more rapid. I am weaker than you. I didn't know you existed until I received your communication information, and the chain of suspicion between us was established. During this period, I may have a technical explosion at any time, and I will walk far ahead of you at once and become stronger than you.

You know, on the scale of the universe, hundreds of years is just a flick of a finger, and I know that your existence and the information you get from communication may be the best fuse for the technological explosion. Therefore, even if I am just a baby civilization, a budding civilization, it is full of dangers for you. "

If you are better than me, since I can find you, then one day you can also find me, so there will be a string of doubts between us; If you are weaker than me, but there may be a technical explosion at any time, it will become the first situation. To sum up, first, let you know my existence; Second, it is dangerous for me to let you exist, which violates the first axiom. "

The universe is like a dark forest. Every civilization is a hunter with a gun. If you find life, because it is impossible to judge whether they will pose a threat to yourself, you must pre-empt them and destroy them. Therefore, in this forest, any civilization that exposes its existence will soon be eliminated.

Luo Ji threatened the three-body system, and if it didn't stop attacking the Earth, it would detonate a large number of nuclear bombs deployed by human beings in the solar system.

At that time, the solar system and three-body galaxies will be exposed to the dark forest and face the fate of destruction. "

Different from the internet society, after you have a good idea, you can develop it yourself, fight the price war and buy it. But in the universe, people can't get feedback from each other quickly, and they can't communicate with each other (expose their positions). They can only destroy a target when they vaguely see it to protect themselves.

The chain of doubt reflects the selfishness and suspicion of human nature, and only believes in oneself, which reminds me of that sentence, kindness to the enemy is cruelty to oneself.

The technological explosion reflects that, due to the inconsistency of the time background and time dimension of the existence of various civilizations, two strangers, human beings and civilization, are unwilling to show their cards easily because they are uncertain about the development speed of each other's technology and civilization, just as people are often unwilling to be the first bidder in negotiations, hoping that the other party's offer will be higher than their own low price by luck, but they don't know that the other party often drops a lot on the basis of their original bottom line, resulting in their own passive situation.

The second story has gradually come to an end. This sci-fi masterpiece gave me a powerful shock through exquisite data and words, and also let me see many methods and game theories in business.
