Chapter 21 Three-Body Einstein’s Pendulum Big Tear

When Wang Miao entered "The Three-Body Problem" for the fifth time, the world at dawn had changed beyond recognition. The Great Pyramid that appeared in the previous four times had been destroyed in the "Three Days", and a tall modern building appeared in its place.

The appearance of the black and gray building was very familiar to Wang Miao. It was the United Nations Building. On the ground in the distance, there were many tall buildings that were obviously dry warehouses. They all had fully reflective mirror surfaces, which looked like giant giants growing on the ground in the morning light.

crystal plant.

Wang Miao heard a violin sound, which seemed to be a piece of music by Mozart. He was not skilled in playing it, but it had a very special charm, as if it always meant that it was played for him and he also appreciated it. The sound of the violin came from

There was an old homeless 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 at his feet, and someone seemed to have put some change in it.

Wang Miao suddenly discovered that the sun was rising, but the sun rose from under 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 was very big, and half of the sun's disc rose.

Taking up one-third of the horizon. Wang Miao's heartbeat accelerated. Such a huge sun could only mean another great destruction. But when he looked back, he saw the old man still sitting there playing the piano as if nothing had happened.

Her silver hair seemed to be burning in the sun's rays.

The sun was silver, the same color as the old man's hair. It spread a silver light to the earth, but Wang Miao couldn't feel any warmth from the light. He looked at the sun that had completely risen above the horizon.

On the huge plate that emitted silver light, he clearly saw the wood grain-like figures, which were solid mountains. Wang Miao understood that they did not emit light themselves, but only reflected the light of the real sun that emitted morning light from another direction, rising up.

What rose was not the sun, but a giant moon! The giant moon moved very fast, passing through the sky at a speed that could be detected by the naked eye. In the process, it gradually melted from a full moon into a half moon, and then turned into a crescent moon. Old man

The soothing sound of the violin floated in the cold morning breeze, and the magnificent scene in the universe seemed to be the materialization of the music. Wang Miao was intoxicated by the shock of beauty. The huge crescent moon set in the morning light, and its brightness increased a lot at this time.

When only its two silvery pointed horns were left above the horizon, Wang Miao suddenly imagined it as the two horns of a giant cosmic bull running towards the sun.

"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 very long and the curves were soft, as if he was trying to create a kind of harmony.

"You are right, I am Einstein, a poor man who had full faith in God but was abandoned by him."

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

"It has cooled down."

"who?"

"The big moon. When I was a kid, it was still hot. When it rose to the zenith, I could see the red light on the core plain. Now it has cooled down...haven't you heard of the Great Rip?"

"No, what's going on?"

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

"How did you end up in this situation?" Wang Miao dug into his pocket and actually took out some change. He bent down and put the money into his 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 the human sequence in the East is very close to the correct one, but there are some differences.

That little bit is an insurmountable gap for Newton or others. I have always believed that without me, others would have discovered the special theory of relativity, but this is not the case with the general theory of relativity. The little bit that Newton missed is what the general theory of relativity points out.

Although the error caused by the gravitational perturbation of the planet's orbit described is very small, it is fatal to the calculation results. By adding the correction of gravitational perturbation to the classical equation, a correct mathematical model is obtained. Its computational complexity is

What you've done in the East is much bigger, but for modern computers, it's really not a problem."

"Have the calculation results been confirmed by astronomical observations?"

"Would I be here if that were the case? But aesthetically speaking, I was right, the universe was wrong. God abandoned me, then everyone abandoned me, I wasn't wanted anywhere, Princeton revoked my

UNESCO didn’t even offer me a professorship or a scientific advisor position. They begged me on their knees before and I refused to do it. I even wanted to be the president of Israel, but they said they had changed their minds and that I couldn’t do it.

He’s a liar. Sigh——”

After Einstein finished speaking, he played the piano again, picking up exactly where he left off. Wang Miao listened for a while and then walked towards the door of the building.

"There is no one inside. Everyone attending this session of the UN General Assembly is behind the building participating in the pendulum launching ceremony." Einstein said while playing the piano.

Wang Miao walked around the building and came to the back of it, and immediately saw something incredible: a giant pendulum that towered over the sky. In fact, a section of it could be seen in front of the building, but Wang Miao didn't know it at the time.

What is it? This is the giant pendulum built by Fuxi that Wang Miao saw on the land during the Warring States Period when he first entered "Three-Body". It was used to hypnotize the sun god. The appearance of the giant pendulum in front of him has been modernized.

, the two tall towers supporting the overpass are all-metal structures, each as tall as the Eiffel Tower. The pendulum is also made of metal, streamlined, with a smooth electroplated mirror surface. Due to the high-strength materials, the wires that suspend the pendulum

There is only one very thin cable and is almost invisible, which makes the pendulum appear to be hanging in the air between two tall towers.

Under the huge pendulum, there was a group of people in suits, probably the heads of state attending the UN General Assembly meeting. They were talking in small groups in low voices, as if they were waiting for something.

"Ah, Copernicus, a man who spanned five eras!" someone shouted, and others welcomed him.

"Besides, you are the one who saw the pendulum with your own eyes during the Warring States Period!" A kind-looking black man said, 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 it being built again now?" Wang Miao asked.

"It is a three-body monument and a tombstone." The Secretary-General said, looking up at the pendulum in mid-air. From here, it is as big as a submarine.

"Tombstone? Whose is it?"

"An effort, an effort that has lasted for 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?"

"As of now, it's completely over."

Wang Miao hesitated for a moment and took out a stack of information. This was a link to Wei Cheng's mathematical model of the three-body problem. "I...came here just for this. 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. They all left him and returned to their own small circle to continue the chat. He noticed that some people smiled and shook their heads when they left. The Secretary-General took

After passing the information, he handed it to a tall, thin man wearing glasses next to him without even looking at it. "Out of respect for your lofty prestige, please ask my scientific advisor to take a look at it. In fact, everyone has already expressed this to you."

Respect, if it were anyone else, it would immediately attract ridicule."

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

"What do you mean, someone has already created this mathematical model?"

"Yes, there are dozens of other mathematical models, more than half of which are much more advanced than yours, and have been created and calculated on computers. In the past two centuries, this huge amount of

Calculation is the central activity of the world, and people wait for the results as if they were waiting for the Day of Judgment."

"The results of it?"

"It has been conclusively proven that the three-body problem has no solution."

Wang Miao looked up at the huge pendulum. It shone brightly in the morning light, reflecting everything around it as a deformed mirror, as if it were the eye of the world. In that distant era that had been separated by many civilizations, it was here.

On the vast land, he and King Wen of Zhou once walked through the giant pendulums towards King Zhou's palace. In this way, history drew a long circle and returned to the original place.

"As we have long guessed, the three-body system is a chaotic system that will infinitely amplify small perturbations, and its operating rules are mathematically unpredictable in nature." said the scientific consultant.

Wang Miao felt that all his scientific knowledge and ideological system were blurred in an instant, and he was replaced by unprecedented confusion. "If even an extremely simple system like the three-body system is in unpredictable chaos, how can we explore complex systems?"

Do you have faith in the laws of the universe?"

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

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 again from the horizon on the dark night side. Its silver giant image was reflected on the smooth surface of the pendulum, moving in strange ways, as if there was a mysterious telepathy between the pendulum and the giant moon.

"You talked about civilization. This civilization seems to have developed to a considerable height." Wang Miao said.

"Yes, we have mastered nuclear energy and entered the information age." The Secretary-General said, but he seemed not to take it seriously.

"Then there is such a hope: civilization will continue to develop and reach another level. Although it cannot know the laws of the sun's movement, it can survive in chaotic eras and be able to withstand the devastating catastrophes caused by the abnormal movement of the sun in the past.

disaster."

"People used to think this way, and this was one of the driving forces behind the Trisolaran civilization's tenacious regeneration, but it made us realize how naive this idea is." The Secretary-General pointed to the rising giant moon and said,

"This may be the first time you have seen this huge moon. In fact, it is almost a quarter of the size of our planet. It is no longer a moon, but a companion star of this planet. It is the product of a big tear.

.”

"The Big Tear?"

"The catastrophe that destroyed the last round of civilization. In fact, compared with previous civilizations, the warning period for this disaster was still quite long. The remaining records show that astronomers from the 191th civilization had long observed the 'flying star'

move'."

Hearing the last four words, Wang Miao's heart tightened. "The flying star is motionless" is the biggest bad omen in the Trisolaran world. The flying star, or the sun in the distance, looks stationary on the background of the universe from the perspective of ground observation.

It only means that the sun and the planets are moving in a straight line. There are three possibilities: 1. The sun and the planets are moving in the same direction at the same speed; 2. the sun is moving away from the planets; 3. the sun is rushing towards the planets.

Before Civilization 191, this was just an imaginary disaster that had never actually happened. However, people’s fear and vigilance against it did not relax at all, so that “the flying star does not move” became a common phenomenon in many Trisolaran civilizations.

The most unlucky curse. Even if there is only one flying star stationary, it still makes people shudder.

"At that time, three flying stars were stationary at the same time. The people of Civilization No. 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, one sun moved into the visible distance of the outer atmosphere. In the quiet night sky, the flying star suddenly transformed into a blazing sun. At an interval of more than thirty hours, the other two suns also appeared one after another. This

It is not a "three-day sky" in the general sense. When the last flying star turns into the sun, the first visible sun has passed by the planet from a very close distance, and then the other two suns have passed from a closer distance.

Passing by! The tidal forces exerted 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 a large crack on the planet that led directly to the core of the earth.

, the third sun tore the planet in half."

The Secretary-General pointed to the giant moon that had risen to the sky, "This is the smaller half. It has the ruins left by Civilization No. 191, but it is already a lifeless world. It is the most thrilling in the entire history of Trisolaris.

disaster, when the planet was torn apart, the two irregular-shaped parts became spherical again under their own gravity, the hot and dense core material of the planet surged to the ground, the ocean boiled on the magma, and the continents floated like melting ice.

After they collide, the earth becomes as soft as the ocean, and huge mountains tens of thousands of meters can rise in an hour and disappear in the same short period of time. Within a period of time, the two parts of the planet that were torn apart were disconnected.

There is a river of magma across space between them. The magma cooled in space and formed a ring around the planet. However, due to the gravitational disturbance of the two parts of the planet, the ring was unstable, and the rocks that made it fell one after another, causing the world to
