What is the law of the dark forest in the universe?

This article is intended to tell people who don't have time to watch "Three-body" what "Three-body: Dark Forest" tells.

At the end of the last book "The Past of the Earth", the three-body came, and the final exchange said: You are bugs. ......

In the face of such humiliation, we can only ... suffer ... the difference between the earth civilization and the three-body civilization is not the same level, and many science and technology fans are desperately fleeing the earth. But think about Xiao Qiang. He won't be killed. The earth's environment has been destroyed like this, and the bugs that are deeply hated by human beings are still not extinct! The strong man decided to start resisting. So there was a "face-to-face plan"; (face wall? I probably want to become a Buddha in nine years. The selected face-to-face lecturer can do whatever he wants without explaining to anyone. Once explained, it is heard by the three-body and destroyed. Among the remaining Adventists, there are also corresponding wall-breaking, mainly to study what these people want to do and whether they pose a threat to the "Lord".

1.？ Face wall plan and broken wall person

The United Nations has elected four outstanding figures. Among them, our hero appeared, and his name was Luo Ji. Unlike the other three people with dazzling resumes, Luo Ji is a doctor with a happy life, just like Zhang Xiaofan in Zhu Xian. He didn't want to do this, but it was up to him, so he decided to find a dream place for his old age, which he called "part of the plan"

This place is very interesting. Luo Ji requires snow-capped mountains, forests, grasslands and lakes, and the environment should be original enough. At the same time, he also asked the house next to him to be fully equipped and modern enough. Isn't this the contradiction in the hearts of most modern people? Even the original ecological environment can't let go of the convenience of modern life. Dr Luo Ji is also very interesting. He asked to take himself to this place without telling him the specific location. He thinks that once you know the location, the world is a map, and as long as you don't know the coordinates, the world is truly vast. Poverty has limited my imagination. There really is such a place, so Luo Ji lives in an old castle, reading books, riding horses, playing golf, carefree and indifferent to the world.

Enjoy a single life and have plenty of food and clothing. . . Luo Ji thinks she still needs a girl of her dreams. So using all human resources, Luo Ji found Zhuang Yan. Start the life of a fairy couple. While others are trying to live a normal life. This may be the difference between learning god and learning scum before the final exam.

One of them wants to kill all mankind, turn the human after death into a quantum army of the dead, so that a quantum ghost can no longer die, and this ghost army will be invincible. Such a crazy anti-human idea was seen through the broken wall and made public. Even though he has admitted that he really wants to form a quantum ghost by killing all human beings, the public doesn't believe it. The public still thinks that this must be a disguise of a face-changing person. Anyway, the great face man is always right. Faceless people can't stand the crowd's "smile at faceless people" No one believed it and committed suicide. The other two people have felt Naoko's obstruction in human science and decided to freeze their sleep and wake up four centuries later to support the Star Wars at that time.

And our doctor, Dr. Luo Ji, married and had children with Ms. Zhuang Yan, and lived a happy life known as "one of the profile projects".

2.？ Broken Wall Man-Luo Ji

However, mankind is still in crisis. In order to urge Dr. Luo Ji's plan, Zhuang Yan and their children were frozen to sleep by the United Nations on a dark night until four centuries later. Luo Ji asked to freeze himself, but think about it. Four centuries later, the family was reunited, and then everyone died together. Forget it. Dr Luo Ji finally remembered to think about why he chose to be his sidekick. He is ordinary, but Santi wants to kill him, and even makes the scene an accident to hide his eyes and ears (so the United Nations attaches importance to him, and if Santi lets nature take its course, let Luo Ji live and die like an ordinary person ...). Then why is Santi afraid of him? Luo Ji recalled his mediocre first half of his life simply because he had talked to Ye, who had told him two laws and two concepts to develop the whole sociology of the universe. It can be said that all the plots in the second part from beginning to end are explaining these two laws and two concepts:

So Luo Ji finally did the same thing as Ye. He sent a message to the universe (Luo Ji called it a spell)-the coordinates of an inanimate star 50 light-years away from the earth, and described the planets around this coordinate, sent it to the whole universe with the help of the sun, and then went to hibernate by himself, waiting for the result after 100 years. Before he hibernated, unfortunately, Sandy knew about his experiment and developed a "gene missile". As long as Luo Ji is infected with the virus, it will release the toxin, so under the protection of 200 meters underground, Luo Ji hibernates with the virus.

At the same time, the villagers of the earth also built a space elevator and controlled the nuclear fusion technology. There are also many reserve space soldiers in hibernation, ready to reinforce the future, including Zhang Beihai, another genius.

Eight years later, one of the hibernating people thawed. During his hibernation, his wife developed a new brain technology-"thinking seal", and voluntarily transplanted the idea that "human beings can overcome the three-body" into the brains of soldiers who wanted to escape. At first, everyone opposed it. What's the difference between human beings without free thinking and extinction! However, this faceless man made the auditor compromise by letting humans choose implantation and strict control. Seeing his ideas put into practice, the faceless man went to hibernate again.

Another man with a side wall was trapped by a broken wall. He wanted to explode Mercury with a hydrogen bomb, causing a vortex in the solar system, so that the sun and the three-body would perish together. It's so anti-human, the United Nations revoked his status as a faceless person.

Luo Ji is the only one among the four people who has to face the wall.

3.？ new century

150 years, Luo Ji was thawing, and his virus was cured in his sleep. But the world doesn't need him anymore.

During the period of 150, human beings have developed into a period of great depression, and there are scenes of famine and cannibalism everywhere. Humans no longer blindly deal with trisomy. We began to pay attention to improving the status quo of hunger, so we had the second enlightenment, the second Renaissance, and the liberation of human nature brought about explosive breakthroughs in technology, so we had today's dungeons and space countries.

At this time, besides the land boundary, the earth is divided into three countries, and there are three space countries, which are independent of the ground. This is a brand-new century. Humans live under branches and leaves. The ground is full of sand cities, and food can no longer grow. 1000 meters underground residence, using microwave power supply, the language is mixed with Chinese and English. The land can no longer grow food, but can only be synthesized, and the sunlight returns from the pictures taken in space.

The side wall plan was officially cancelled. The inventor of the side wall who invented the "steel seal of thinking", his wife told him the secret. His wife is a wall breaker. This pioneer is actually a defeatist. He passed on the "thinking stamp machine" that "human beings can't defeat the three-body" to future generations. At this time, the three-body surplus party was eliminated, and these "steel seal families" became a new threat.

At this point, three of the four people have gone far. Only Luo Ji can adapt to this new world. Looking back, the "face-to-face plan", originally formed to deal with Naoko, has become a platform for face-to-face people to hide their thoughts on human beings, which is awesome.

The civilization of the earth has developed to this point, and all people are complacent. Two centuries ago, a drop of pioneer "water drop" sent by Santi also reached the earth at this time. The earth lists its founders, and it is ready to confront it in space with the cheers of everyone. The scientific and technological achievements that once made mankind proud were solved in two or three minutes by third cosmic velocity, who was ten times as big as a "water drop". Yes, the three-body is saying: you are bugs.

4.？ Cosmic sociology

In this war, a starship escaped. From Zhang Beihai, who came two centuries ago, he saw that the great and low times predicted by his fathers, the second Renaissance and the present scientific and technological life have all been realized one by one, that is to say, the prediction of human failure in this battle is inevitable. So he ran away and chased his battleship with him. He only saved five battleships, and with the last hope of mankind, he drifted in the vast universe and began a new history of interstellar earth.

And these five warships make up a very small universe. The energy of five warships in the universe is gradually exhausted. Only by combining the energy and resources of five warships can we feed the demand of one warship. "Survival is the first demand of civilization"! Which warship should stay? Everyone wants to live. What if others attack first to seize resources? They couldn't stop doubting each other, and they began to attack each other. Finally, only one warship was left floating in the distance, and a new "inhuman" human civilization began.

On this side of the earth, human beings haven't really met the three-body yet, and a small "water drop" has destroyed all the scientific and technological achievements of human beings. Modern people have collapsed.

Luo Ji saw the end of World War V and knew that he was right. "Water Drop" came to kill him. He wants to protect himself. Even if everyone laughs at his romance, "water drops" stop near the sun. "Water drops" constantly send strong electromagnetic waves to the sun, blocking all the bands of the sun. Without the sun, Luo Ji can no longer send any information to the universe.

At this time, 150 years ago, Luo Ji's spell came true, and the star under Luo Ji's spell exploded. At this time, Luo Ji became the spokesman and savior of mankind.

So Luo Ji began to explain this "Cosmic Sociology". There are countless civilizations in the universe, and the earth is just one of them. The most basic need of these civilizations is survival, which means continuous expansion, just like people on earth want to immigrate to Mars, but for the whole universe, all materials are unchanged. The expansion of an earth will occupy the resources of Mars. Just like five warships, they always have the same energy. If they want to survive, they can only take the resources of other warships for themselves, and there will be wars and killings. This is the basic explanation of those two theorems.

In the universe, even if each other's resources are enough for their own use, there is still a "chain of suspicion". You can't judge whether an unknown civilization is an enemy or a friend to you, and the other side can't judge whether you are an enemy or a friend. What you are worried about is that even if you are well-intentioned, what if the other party regards you as an enemy and attacks you first? So back and forth, the terminal of the chain of suspicion is preemptive. Once there is communication between the two civilizations, there will be a series of suspicions. Even if the other person is much weaker than you, you can't rest assured, and there has been a "technical explosion." It took 200 years for mankind to go from the industrial age to the atomic age, while it took only a few decades for the atomic age to the information age. The growth of technology may be in the foreseeable future, or it may be exponential growth from a certain point in time. Therefore, as long as you expose yourself in the universe, it is death.

This is the law of the black forest. In the black forest, there are countless hunters hiding in the dark. These hunters know the jungle law of "Cosmic Sociology". They carefully hide themselves. Once the position is exposed, all pistols will shoot at it. The victim never knows where the bullet came from. Liu answered the "Fermi Paradox" in cosmic civilization like this-"Where are the aliens?" . Liu: "Aliens hide in the dark and will not expose themselves easily".

So when Luo Ji sent the coordinates of a star to the whole universe, 100 years later, the star exploded and was hit.

What about the earth? In order to prevent the earth from sending three-body coordinates to the universe, the sun is disturbed by "water droplets". Luo Ji began to plan more carefully after he regained his status as a "faceless man". He arranged the nuclear bomb he had made before around the sun, hoping to use the sun's flicker when the nuclear bomb broke out to send out information containing three-body coordinates, but it also exposed the coordinates of the solar system.

Like others, Luo Ji's practice may make all mankind perish, but only in this way can the three-body be threatened.

Sandy didn't want to die together, so she held peace talks with human beings to help them build new launch bases and develop science and technology. Luo Ji's wife and children were finally thawed and the family was reunited.

From being threatened by the three-body to threatening the three-body compromise. Luo Ji saved all mankind, including his wife and children.

To be continued. . . Death lives forever. . .
