Three bodies

When Wang Miao entered "Three-Body Problem" for the fifth time, the world in the dawn had changed beyond recognition.The Great Pyramid that had appeared in the previous four times had been destroyed in the "Three-day Lianzhu", and a tall modern building appeared in that position. Wang Miao was familiar with the appearance of this black-gray building. It was the United Nations building.On the land in the distance, there are many tall buildings that are obviously dry warehouses, all of which have fully reflective mirror surfaces, like giant crystal plants growing on the ground in the morning light.

Wang Miao heard the sound of a violin, which seemed to be a piece of Mozart's music. He did not play it proficiently, but it had a very special charm, as if it was always explaining that it was played for himself, and he liked it very much.The sound of the piano came from a homeless old man sitting on the steps of the main entrance of the building, his fluffy silver hair fluttering in the wind.There was a broken top hat under his feet, and it seemed that someone had already put some change in it.

Wang Miao suddenly discovered that the sun was rising, but the sun was rising from the horizon in the opposite direction to the morning light. The sky there was still a dark night sky, and there was no morning light before the sun rose.The sun is so big that the half-rising sun disk occupies one-third of the horizon.Wang Miao's heart beat faster, such a big sun can only mean another catastrophe.But when he looked back, he saw the old man still sitting there playing the piano as if nothing had happened, his silver hair seemed to be burning in the sun's rays.

The sun is silver, the same color as the old man's hair, and it sprinkles a piece of silver light on the earth, but Wang Miao can't feel any warmth from this light.He looked at the sun that had completely risen above the horizon, and from the huge silver disk, he could clearly see the grainy patterns, which were solid mountains.Wang Miao understood that it does not emit light itself, but only reflects the light of the real sun that emits morning light from another direction. What rises is not the sun, but a giant moon!The giant moon moved very fast, gliding across the sky at a speed detectable by the naked eye. In the process, it gradually melted from a full moon to a half moon, and then turned into a crescent again. The soothing sound of the old man's violin wafted in the cold morning wind , the magnificent scene in the universe seems to be the materialization of the music, and Wang Miao is intoxicated by the awe of beauty.The huge crescent moon set in the morning light, and its brightness increased a lot. When only two silvery sharp horns remained above the horizon, Wang Miao suddenly imagined it as a giant cosmic cow running towards the sun. two horns.

"Dear Copernicus, please stop your hurried steps, so that you can enjoy a piece of Mozart, and I will have lunch." After the giant moon completely set, the old man raised his head and said.

"If I'm not mistaken—" Wang Miao said, looking at the wrinkled face. The wrinkles were long and the curves were soft, as if trying to create a harmony.

"You're right, I'm Einstein, a poor man who believed in God but was abandoned by him."

"What happened to the big moon just now? I haven't seen it in the past few times."

"It's cooled off."

"Who?"

"The big moon, it was still hot when I was a child, and when it rose to the mid-heaven, I could see the red light on the core plain, but now it's cooling down... haven't you heard of the big rip?"

"No, what's going on?"

Einstein sighed and shook his head, "Don't mention it, the past is too bad to look back on. My past, the past of civilization, and the past of the universe are all too hard to look back on!"

"How did you get to this point?" Wang Miao dug out his pocket, and actually took out some change. He bent down and put the money into the hat.

"Thank you, Mr. Copernicus, I hope God will not abandon you, but I have no confidence in this. I feel that the model you and Newton used to calculate in the East is very close to correct, but the difference That little bit is an insurmountable gap for Newton or anyone else. I always thought that without me, someone else would have discovered special relativity, but not general relativity. The point where Newton is short is what general relativity is. The gravitational perturbation of planetary orbits described, although the error caused by it is very small, it is fatal to the calculation results. Adding the correction of gravitational perturbation to the classical equations, the correct mathematical model is obtained. Its calculation is more than What you've done in the East is much bigger, but with modern computers, it's really not a problem."

"Has the calculation result been confirmed by astronomical observations?"

"Would I be here then? But aesthetically, I'm right, the universe is wrong. God abandoned me, then everyone abandoned me, I was not wanted anywhere, and Princeton revoked my As for the professorship, UNESCO didn’t even give me a scientific advisor position. They begged me on their knees before, and I didn’t do it. I even wanted to become the president of Israel, but they said they had changed their minds, saying that I could not do it. A liar. Well—"

After Einstein finished speaking, he played the piano again, very precisely starting from where he left off.After listening for a while, Wang Miao walked towards the gate of the building.

"There is no one inside. All the people who participated in this session of the General Assembly participated in the pendulum launching ceremony behind the building." Einstein said while playing the piano.

Wang Miao walked around the building, went behind it, and immediately saw an unbelievable thing: a giant pendulum towering up to the sky.In fact, a part of it could be seen in front of the building, but Wang Miao didn't know what it was at the time.This is the kind of giant pendulum built by Fuxi that Wang Miao saw on the land of the Warring States Period when he first entered "Three-Body Problem", which was used to hypnotize the sun god.The shape of the giant pendulum in front of me has been modernized. The two towers supporting the bridge are all metal structures, each as high as the Eiffel Tower. The pendulum is also made of metal, in a streamlined shape. Material, the cable that suspends the pendulum is only a very thin one, which is almost invisible, which makes the pendulum appear to be suspended in the air between two tall towers.

Under the giant swing, there is a group of people in suits, who may be the heads of state attending the UN General Assembly.They talked in low voices in small groups, as if waiting for something.

"O Copernicus, man of five epochs!" someone shouted, and others greeted him.

"Besides, you were the one who saw the pendulum with your own eyes in the Warring States Period!" A kind-faced black man said while holding Wang Miao's hand.Someone introduced him as the current Secretary-General of the United Nations.

"Yes, I have seen it, but why is this thing built now?" Wang Miao asked.

"It's a monument to the Three-Body Problem, and it's also a tombstone." The Secretary-General said, looking up at the pendulum in mid-air. Seen from here, it was as big as a submarine.

"Tombstone? Whose?"

"An effort, an effort that lasted nearly two hundred civilizations, an effort to solve the three-body problem, and an effort to find the laws of the sun's movement."

"Is this effort over?"

"So far, it's completely over."

Wang Miao hesitated for a moment, and took out a stack of materials, which was a link to Wei Cheng's mathematical model of the three-body problem. "I... came here for this purpose. I brought a mathematical model to solve the three-body problem..."

As soon as Wang Miao spoke, he found that the people around him immediately lost interest in him, and they all left him and returned to his small circle to continue the chat just now. He noticed that some people shook their heads with a smile when they left.The Secretary-General took the information and handed it to a tall, thin man wearing glasses without looking at it, "Out of respect for your lofty prestige, please ask my scientific advisor to take a look. In fact, everyone has already told you Without this kind of respect, if you change someone else, you will immediately be ridiculed."

The scientific advisor took over the information and flipped through it, "Evolutionary algorithm? Copernicus, you are a genius. Anyone who can come up with this kind of algorithm is a genius. In addition to superb mathematical ability, it also requires imagination."

"Listen to you, someone has already created this mathematical model?"

"Yes, there are dozens of other mathematical models, more than half of which are much more sophisticated than yours, have been created and completed on computers. Over the past two centuries, this huge amount of Computing is the central activity of the world, and people await the results as if they were waiting for Judgment Day."

"The results of it?"

"It has been definitively proved that there is no solution to the three-body problem."

Wang Miao looked up at the huge pendulum, which was shining brightly in the morning light, as a deformed mirror reflecting everything around it, like the eyes of the world.In that distant era that has been separated by many civilizations, on this land, he and King Wen of Zhou walked to King Zhou's palace through the giant pendulums.In this way, history has drawn a long circle and returned to the original place.

"As we have guessed for a long time, the three-body system is a chaotic system, which will amplify tiny disturbances infinitely, and its operation law is unpredictable in terms of mathematics." The scientific consultant said.

Wang Miao felt that all his scientific knowledge and thought system were blurred in an instant, replaced by unprecedented confusion, "If even an extremely simple system like the three-body system is in unpredictable chaos, how can we explore complex Do you have confidence in the laws of the universe?"

"God is a shameless old gambler, he has abandoned us!" Einstein came over at some point and said, waving his violin.

The secretary-general nodded slowly, "Yes, God is a gambler. The only hope for the Trisolaran civilization is to take a gamble."

At this time, the giant moon rose from the dark side of the sky again, and its silver giant image was reflected on the smooth surface of the pendulum, wriggling strangely, as if there was a mysterious telepathy between the pendulum and the giant moon.

"When you talk about civilization, it seems that this civilization has developed to a considerable height." Wang Miao said.

"Yes, mastered nuclear power, and the information age," said the Secretary-General, but seemed to take all this lightly.

"Then there is such a hope that civilization will continue to develop and reach another height. Although the law of the sun's movement cannot be known, it can survive in the chaotic era and resist the devastating catastrophic events caused by the abnormal movement of the sun in the past. disaster."

"People used to think this way, and this is one of the motivations for the Trisolaran civilization to continue its tenacious regeneration, but it made us realize how naive this idea is." The Secretary-General pointed to the rising moon and said, "You may be seeing this huge moon for the first time. In fact, it is almost a quarter of the size of our planet. It is not a moon, but a companion star of this planet. It is a product of the big rip .”

"Big tear?"

"The catastrophe that destroyed the last round of civilization. In fact, compared with previous civilizations, the warning period for this disaster is still quite long. The remaining records show that the astronomers of civilization 191 observed the 'flying stars are not move'."

Hearing the last four words, Wang Miao's heart tightened. "Flying star does not move" is the greatest omen of the Trisolaran world. The flying star, or the sun in the distance, has stopped on the background of the universe from the perspective of observation from the ground, which only means that the sun and the planets are moving in a straight line. There are three possibilities: 191. The sun and the planets are moving in the same direction at the same speed; [-]. The sun is moving away from the planets; [-]. The sun is rushing towards the planets.Before Civilization [-], this was just an imaginary disaster that never happened in reality, but people's fear and vigilance against it never let up, so that "flying stars don't move" became a symbol in multiple Trisolaran civilizations. A most inauspicious spell.Even if only one flying star is still, it is chilling.

"At that time, the three flying stars were stationary at the same time. The people of Civilization 191 stood on the ground helplessly looking at the three flying stars hovering in the sky, and at the three suns rushing towards their world. A few days later, a sun moved to the visible distance of the outer atmosphere, and in the quiet night sky, the flying star suddenly changed into a blazing sun, and at intervals of more than 30 hours, the other two suns also appeared one after another. This is not In the general sense of "three-day volley", when the last flying star turns into a sun, the first visible sun has passed the planet from a very close distance, and then the other two suns have passed the planet from a closer distance one after another Exactly! The tidal forces produced by the three suns on the planet all exceeded the Roche limit[10], the first sun shook the deepest geological structure of the planet, and the second sun tore open a large crack leading directly to the earth’s core on the planet, The third sun tore the planet in half."

The Secretary-General pointed to the huge moon that had risen to the sky, "This is the smaller half. There are ruins left by Civilization 191 on it, but it is already a lifeless world. It is the most thrilling in the entire history of the Trisolaran world." When the planet was torn apart, the irregularly shaped two parts became spherical again under their own gravity, the scorching hot and dense planetary core material rushed to the ground, the ocean boiled on the magma, and the continent floated like melting drift ice. After they collided, the earth became as soft as the ocean, and huge mountains of tens of thousands of meters could rise in an hour and disappear in the same short time. In a period of time, the two parts of the planet that were torn apart were disconnected, Between them was a river of magma across space, which cooled in space and formed a ring around the planet, but due to gravitational perturbations of the two parts of the planet, the ring became unstable, and the rocks of which it was composed fell, leaving the world Being in the meteorite rain that lasted for several centuries... Can you imagine what kind of hell it is! The damage to the ecological circle of this disaster is the most serious in all history. The life on the companion star has been extinct, and the parent star has almost become It became a lifeless world, but the seeds of life germinated here again. As the geological state of the parent planet gradually stabilized, evolution began to falter again in the unrecognizable continents and oceans, until the 190th emergence of civilization , this process took 9000 million years."

"The universe in which Trisolaris lives is more cruel than we imagined. What will happen next time when the 'flying star does not move'? There is a great possibility that our planet will no longer skim the edge of the sun, but plunge into the sun In the sea of ​​​​flames. As time goes on, this possibility is almost certain."

"This was originally just a terrible speculation, but a recent astronomical discovery has made us completely desperate for the fate of Trisolaran. This study aims to speculate that the stars and The history of planet formation. I accidentally discovered that there were twelve planets in the Trisolaran galaxy a long time ago! Now we are the only one left. There is only one explanation: in the long astronomical time, those eleven planets The planets were all swallowed by three suns! Our world is nothing but the remnants of this great cosmic hunt. It is just a kind of luck that civilization can go through 190 times of reincarnation. Through further research, we also found The breathing phenomenon of these three stars."

"Stellar Breathing?"

"Just an analogy. You discover the outer gaseous layer of a star, but what you don't know is that this gaseous layer is constantly expanding and contracting in long cycles, like breathing. When the gaseous layer expands, it can increase in thickness More than ten times, this makes the diameter of the star greatly increased, like a giant palm, and it is easier to capture planets. When a planet passes by the sun at close range, it will enter its gaseous layer and decelerate sharply in the violent friction. In the end, like a meteor, it dragged its long fire tail and fell into the sea of ​​flames of the sun. According to research, in the long history of the Trisolaran galaxy, every time the solar atmosphere expanded, it would engulf one or two planets. The three planets fell into the sea of ​​fire one after another when the gaseous layers of the sun expanded to the maximum. Now, the gaseous layers of the three suns are all in a state of contraction, otherwise our planets would have fallen into the sun when they passed by the sun last time. Scholars predict that the most recent expansion will occur in 150 to 200 million years."

"I really can't stay in this ghostly place." Einstein squatted on the ground holding the violin in the posture of an old beggar.

The secretary-general nodded and said, "I can't stay any longer, and I can't stay any longer! The only way out for the Trisolaran civilization is to gamble with this universe."

"How to bet?" Wang Miao asked.

"Fly out of the Trisolaran galaxy, fly to the vast sea of ​​stars, and look for a new world in the Milky Way where you can immigrate!"

At this time, Wang Miao heard a sound of "cracking" and saw that the huge pendulum was being lifted obliquely by a thin cable on a nearby overhead winch, rising to the position where it was released. On the background of the sky, a huge waning moon is sinking in the morning light.

The Secretary-General solemnly announced: "The pendulum starts!"

The overhead winch loosened the thin cable that pulled the pendulum up high, and the gigantic pendulum slid down silently along a smooth arc, falling slowly at first, but accelerating rapidly, reaching its maximum speed when it reached the lowest point, There was a strong sound of wind breaking through the air, and when the sound disappeared, the pendulum had risen to the same height along the same arc trajectory, and after a moment of stagnation, a new round of swing began.Wang Miao felt that the pendulum seemed to generate a huge force in the swing, as if the earth was shaken by it.Different from the simple pendulum in the real world, the swing period of this giant pendulum is not constant and is changing all the time, which is caused by the gravitational changes produced by the giant moon around the parent star: when the giant moon is on this side of the parent star, it The gravitational force with the parent star cancels each other out, and the gravity decreases; when it moves to the other side of the parent star, the gravitational force superimposes, and the gravity almost recovers to before the big tear.

Looking up at the majestic swing of the Three-body Monument, Wang Miao asked himself: Does it express the desire for law, or the submission to chaos?Wang Miao also felt that the pendulum was like a huge metal fist, waving eternally against the cold universe, silently sending out the unyielding cry of the Trisolaran civilization... When Wang Miao's eyes were blurred by tears, he saw the giant pendulum Subtitles that appear in the background:
One year after 450, civilization 192 was destroyed in the flames of the double sun volley, and it evolved into the atomic and information age.

Civilization No. 192 is a milestone of the Three-Body Civilization. It finally proved the unsolvability of the Three-Body Problem, gave up the futile efforts to continue the 191-round civilization, and determined a new direction for civilization in the future.So far, the ultimate goal of the game "Three-Body Problem" has changed, and the new goal is:
Fly to the universe, looking for a new home.

Welcome to log in again.

After quitting "Three-Body Problem", Wang Miao felt very tired like every time. This is really a tiring game, but this time he only took a half-hour break before logging in again.After entering "Three-Body Problem", on the dark background, an unexpected message appeared:

The situation is urgent, the "Three-Body" server will be shut down soon, and you can log in freely during the remaining time, and "Three-Body Problem" will directly switch to the final scene.
