The Great Ravine

The Great Ravine was an era of human history that came about humanity's fixation on the defence of the solar system against the Trisolarans. As the environment continued to decline this led to mass desertification and death of billions of humans. The population of Earth declined from over eight billion to 3.3 billion people. At this point the leaders of humanity agreed to focus on the needs of the people which led to many breakthroughs in technology and a new prosperous era for humanity. Research progress was made in the genetically modified food which meant that people would no longer have hunger issues. New cities were built underground as a matter of defence against Trisolaran bombardment.
Project 596

Project 596, (Miss Qiu (Chinese: 邱小姐, Qiū Xiǎojiě) as code word, Chic-1 by the US intelligence agencies) was the first nuclear weapons test conducted by the People's Republic of China, detonated on 16 October 1964, at the Lop Nur test site. The atomic bomb was a part of China's "Two Bombs, One Satellite" program.
Frontiers of Science

Frontiers of Science (科学边界) is a physics organization. Ding Yi describes it as follows:

"It is famous in academia. Its core goal is a response to the following: Since the second half of the twentieth century, physics has gradually lost the concision and simplicity of its classical theories. Modern theoretical models have become more and more complex, vague, and uncertain. Experimental verification has become more difficult as well. This is a sign that the forefront of physics research seems to be hitting a wall.

“Members of the Frontiers of Science want to attempt a new way of thinking. To put it simply, they want to use the methods of science to discover the limits of science, to try to find out if there is a limit to how deeply and precisely science can know nature—a boundary beyond which science cannot go. The development of modern physics seems to suggest that such a line has been touched.”
Entropy

## Information theory

In information theory, entropy is defined as

# H
−
∫
p

log
⁡
p

E
(

log
⁡
p

)

{\displaystyle H = -\int p(x) \log p(x) \ dx = E(-\log p(X))}

where p is a probability distribution of the random variable X. This is related to the concept of entropy in thermodynamics and physics.

The discrete version is

H
(
p
# )
−
∑

p

log
⁡

p

{\displaystyle H(p) = -\sum p\_i \log p\_i }

where

p
(
# X

p

{\displaystyle p(X = x\_i) = p\_i}

 and the random variable X can take on n different values.

We have the constraint

# 1
∑

p

{\displaystyle 1 = \sum p\_i }

To maximize entropy we use lagrange multipliers

\end{align}
}

In other words, when all the

This quantity is used sometimes in natural language processing (e.g. for n-gram models).
Operation Guzheng

**Operation Guzheng** was a military operation conducted by the UN in order to destroy the ship Judgment Day and recover messages that the ETO Adventists had received from the Trisolarans. The operation was named "Guzheng" because the similarity between the nanofilament net used to destroy the ship and the Chinese zither of the same name.

## Trivia

* Operation Guzheng is referenced in the Genshin Impact quest Danger Lurks Everywhere in Fontaine.
Nanotechnology Research Center

## Flying Blade

The main compartment of the gigantic apparatus was a sphere with many pipes connected to it.

They had made small quantities of a new, ultrastrong nanomaterial that they’d given the code name “Flying Blade.” But the samples so far were all made with molecular construction techniques—that is, using a nanoscale molecular probe to stack the molecules one by one, like laying out bricks for a wall. This method was very resource-intensive, and the results might as well have been the world’s most precious jewels. It was impractical to produce large quantities this way.

What the lab is currently doing is to develop a catalytic reaction as a substitute for molecular construction so that large numbers of molecules would stack themselves into the right arrangement. The main reaction chamber could rapidly run through a large number of reactions using different molecular combinations. There were so many combinations that normal manual testing methods would have taken more than a hundred years. In addition, the apparatus augmented actual reactions with mathematical simulations. When the reaction reached a certain stage, the computer would build a mathematical model of it based on intermediate products and finish the remainder of the reaction via simulation. This greatly boosted the experimental efficiency.

And this is when Wang Miao asked to stop the machine, then the number in Wang's sight disappeared.

The Flying Blade was later used to destroy the Judgement Day (The Second Red Coast) on Panama Canal.== References ==

Broadcast Era

The Broadcast Era began once the crew of Gravity and Blue Space activated Gravity's gravitational wave transmitter. Following the Droplet attack on Gravity, Blue Space managed to deflect and destroy the droplets by using the 4th dimensional bubbles which they had access to in that region of space. Following this, the captain of Blue Space notified them that humanity was likely destroyed as this attacked had been planned some time in advance. Captain Chu Yan said the attack took place at exactly the time the new Swordholder assumed their role. As Earth was likely taken they two ships held a vote as to whether they should activate their transmitter for the location of Trisolaris which would also likely destroy Earth and the sun. The vote passed, ending the The Great Resettlement and beginning the Broadcast Era.
V-suit

The V-suit was a very popular piece of equipment among gamers, made up of a panoramic viewing helmet and a haptic feedback suit. The suit allowed the player to experience the sensations of the game: being struck by a fist, being stabbed by a knife, being burned by flames, and so on. It was also capable of generating feelings of extreme heat and cold, even simulating the sensation of being exposed in a snowstorm.
North America I

North America I is one of the space city in the Bunker World. It is the closest city to Asia I and have a spherical construction. Unlike Asia I, small spacecraft could enter the city directly from the gateway at the north pole. There is only one artificial sun in it.

the equator was the lowest point in the city’s simulated gravity, and all the city’s water naturally collected there, forming a sparkling, undulating belt for the city.The water in the sea came from Europa. The dikes along the edge of the sea closest to Jupiter were higher, to avoid the water spilling out when the city accelerated during position adjustments. Even so, when the city had to engage in unexpected maneuvers, small-scale flooding would occur from time to time.

North America I had been completed early on. With a radius of twenty kilometers and twenty million inhabitants, it was the largest city by population. It acted as the prosperous commercial center for all the Jovian cities. Cheng Xin visited this space city in the Death's End.
Earth

**Earth** is the third planet from the sun and densest planet in the universe. It is home to human life and water. It is the only water world in the Solar System. Water covers around 70% of the surface.

Due to the influence of gravity, the Earth orbits around the Sun.

It is said that the Earth is within the Goldilocks Zone away from a star for inhabitable life to exist.
Lightspeed II

Lightspeed II used to be a science city in the bunker world and was one of the two research centers studying how to lower the speed of light to achieve the black domain state, but it had been abandoned. Cheng Xin visited this city with Cao Bin. Cao Bin said there’s no one inside Lightspeed II, and everyone said it is a ghost city. It didn’t spin, and the exterior appeared broken and cracked. In some places, the skin of the city had been ripped open, revealing the structural frame underneath. There is a microscopic black hole with a Schwarzschild radius of twenty nanometers and a mass equivalent to Leda, the Jovian moon in it.

The city was built for studying lowering the speed of light through vacuum. Before making the black hole, they had lowered Leda, one of the smallest moon of Jupitar from its high orbit and turned it into a body orbiting the Sun in parallel with Jupiter, like the city cluster. However, unlike the city cluster, it was located at the Sun-Jupiter L2 Lagrangian point, This allowed it to maintain a stable distance from Jupiter without having to constantly adjust its position. At the time, this was the most massive body humans had managed to move through space until then.

After the microscopic black hole was injected into Leda, it began to absorb mass and rapidly grow. At the same time, the intense radiation generated by material falling into the black hole melted the surrounding rock. Soon, the eight-kilometer-radius Leda melted entirely, and the potato-shaped rock turned into a red-glowing ball of lava. The lava ball shrank slowly, but glowed brighter and brighter, until it finally disappeared with a blinding flash. Observation showed that other than a small amount of material ejected by the radiation, most of the mass of Leda had been absorbed by the black hole. The black hole remained stable, and its Schwarzschild radius, or event horizon radius, had grown from the size of a fundamental particle to twenty-one nanometers. They then constructed Lightspedd II around the black hole.

The black hole was suspended in the middle of the space city, which was empty, didn’t spin, and whose interior was a vacuum connected to space. It was, in essence, a giant container for the black hole. Personnel and equipment could be brought into the city to study the black hole.

The research continued for many years. This was the first time that humans could study a black hole specimen in laboratory conditions, and many discoveries were made that helped with the development of theoretical p
hysics and fundamental cosmology. However, after the incident of 高Way, for a variety of reasons, research on this black hole stopped, and Lightspeed II was abandoned. Now the people are waiting for the black hole to evaporate, which is estimated to take another half century.
Albert Einstein

**Albert Einstein** (阿尔伯特·爱因斯坦) was a physicist who created the theory of relativity (gravity) and made foundational contributions to quantum mechanics.

Born in Germany, he later moved to Princeton, USA, where he spent the rest of his life.

## Trivia

* Einstein had three children: Lieserl Einstein, Eduard Einstein, and Hans Albert Einstein.

Dark forest hypothesis

This is a hypothesis that there are many alien civilizations (life) in the rest of the universe besides human civilization, but we are unable to detect them because these alien civilizations destroy any other civilization that shows any sign of existence. This is one resolution of the Fermi paradox.

Dark forest is also the namesake for the novel Dark Forest.
Fu Xi (Three Body)

Fu Xi is a character who appears in Three Body Problem. He was a man dressed all in black. The black robe blended with the thick shadows in the Great Hall, and the pale white face seemed to float in air.

“He thinks that the sun is a temperamental god. When the god is awake, his moods are unpredictable, and thus we have a Chaotic Era. But when he’s asleep, his breathing evens out, and thus we have a Stable Era. Fu Xi suggested that I build those pendulums you see out there and keep them in constant motion. He claims that the pendulums can have a hypnotic effect on the sun god and cause him to sink into a long slumber. But we can all see that so far, the sun god remains awake, though from time to time he seems to nap briefly.”
The Wandering Earth 2

The Wandering Earth 2 is a film set that released in January 22, 2023 on the first day of the Chinese new year festival. It is the sequel to The Wandering Earth (movie).

It is directed by Frant Gwo and stars Wu Jing, Andy Lau, Zhang Fengyi, and others.

## Robotics

Youibot, a Shenzhen startup, helped provide robots to be used and showcased in the film.

Fraisse

Fraisse is an Aboriginal man who befriends and takes care of AA and Cheng Xin. As a native man he was allowed to keep his home when all humanity was forced into Australia as refugees by the Trisolarans. Either way Fraisse would have rather died than leave his home. Fraisse is in charge of an organization to preserve Aboriginal culture. Unlike most humans, he did not hate Trisolarans.
Wei Cheng

Wei was about forty years old and had the look of a staid, honest intellectual. Wang knew little about him other than his name. Shen hadn’t said much when she introduced him. He didn’t seem to have a job, since he stayed home all day. He never showed any interest in the Frontiers of Science discussions, but seemed used to the sight of so many scholars coming to their house.

But he wasn’t idle. He appeared to be conducting some kind of research at home, always deep in thought. Whenever he met any visitor, he would greet them absentmindedly and then return to his room upstairs. Most of his day was spent there. One time, Wang glanced into his room through the half-open door and saw an astonishing sight: a powerful HP workstation. He was sure of what he saw because the workstation was the same model as the one he used at the Research Center: slate-gray chassis, model RX8620, four years old. It seemed very strange to own a machine costing more than a million yuan just for personal use.
Europe IV

Europe IV is a space city in the Bunker World. Sported a typical football-shaped design, its distinguishing characteristic was the lack of a common artificial sun. Every district had its own miniature fusion sun, and the tiny suns hovered about two hundred to three hundred meters high to provide illumination. The advantage of this approach was that the weightless axis could be more efficiently utilized.

The axis of Europe IV was taken up by the longest—or tallest—building among all the space cities. It was forty kilometers long and connected the north and south poles of the football. Since the interior of the building was weightless, it was mainly used as a spaceport and commercial entertainment district. Europe IV had the smallest population of all the cities, only 4.5 million. It was also the wealthiest city of the Bunker World. Cheng Xin visited this space city in the Death's End.
Quantum (Spaceship)

**Quantum** is a human space warship. Prior to the Doomsday Battle, it entered deep-sea state at Ding Yi’s behest. As soon as the third row of ships had been destroyed, the Quantum entered Ahead Four with Bronze Age and made an emergency escape in the same direction. However, Bronze Age launched a sudden strike on Quantum, using the infrasonic H-bombs to kill off all life inside its Quantum during the Battle of Darkness. The ship’s fuel and critical parts were taken away by the Bronze Age.
Zhang Beihai

Zhang Beihai is a Chinese soldier, a political commissar in the PLA Navy and also a Space Force officer. Although he believes in defeatism, he disguised himself to appear like he had confidence in the victory of humanity.

## Biography

### Crisis Era: Year 3

In this year he joins the Chinese Space Force. He warns the superiors of the space force about defeatism in its ranks. His worry is that the military is too focused on technology that can be revealed by sophon technology. The sophons will also be able to lock technology and humanity will not be able to make large scientific progress. As a result, military personnel will feel that the war is unwinnable.

Zhang Beihai continued his work in the military in order to ensure that the military is both prepared for the Doomsday Battle against Trisolaris forces and also will believe that they can win. The Chinese Space Force organizes various research sectors and Zhang Beihai is the only one to volunteer for the life support and fusion drive sectors.

### Crisis Era: Year 12

In Year 12 of the crisis era, Zhang Beihai seeks out Ding Yi, who is a researcher that has made breakthroughs in fusion drive science. Zhang Beihai is worried that conventional research will not lead to the breakthroughs in science needed to produce ships capable of interstellar travel. He decides that he must kill Ding Yi and the other researchers in order to get to this outcome. He has the idea to fashion weapons using bullets made from meteorites in order to disguise the assassinations in space. When the researchers are posing outside with a large group of others for a group photo, he manages to kill them with the meteorite fired bullets.

He then hibernated as a member of Special Contingent and went to the future, and was selected as the acting captain of *Natural Selection* as a firewall to the Imprinted. This was in fact part of Zhang Beihai's centuries long deception, as he takes *Natural Selection* in an opposite direction away from the meeting of the Trisolaran probe. Fleet command is horrified and asks if he is imprinted, which he denies. He tells them that he knows no matter what humanity does not have a chance to win the victory, therefore humanity must go in a different direction in order to survive. He puts the ships crew into hibernation and takes flight. Fleet command tells him he only has a small portion of fuel and that he will not be able to fly for long with the fleet in pursuit. Despite this, Zhang Beihai is confident in his decision.

He took control of *Natural Selection* and escaped just before the doomsday battle and left a seed of the human civilization in the space. *Natural Selection* and the four spaceships chasing him quickly found the Starship Earth.

However, although he quickly realized that the only way to survive was to kill the rest of the spaceships and take their supplies, he was late to fire and was killed by a faster strike by the Ultimate Law.
Deterrence Era

The Deterrence Era is brought about by Luo Ji as part of his Wallfacer Project. He uses the Dark Forest theory that works through mutually assured self-destruction by broadcasting the locations of Trisolaris and Earth. The human forces use gravitational wave antenna in order to work as deterrence. A Swordholder is the determined by humanity to best and sole controller of this system and Luo Ji is appointed the first Swordholder. He serves in this role until he is a centenarian and is replaced by Cheng Xin. Within an hour of her service as a Swordholder, Cheng Xin is tested by Trisolaran forces and droplets and does not use the Dark Forest button, ending the Deterrence Era and handing control of Earth to the Trisolarans led on Earth by Sophon. In total the Deterrence Era lasted a total of 62 years.

Welcome to...
 **The Three Body Problem Wiki****Remembrance of Earth's Past** (地球往事 *Dìqiú Wǎngshì*), or more colloquially known as **The Three-Body Problem** (三体 *Sān Tǐ*) series from the title of the first book, is a trilogy of science fiction novels written by Liu Cixin. The series has been translated into English by Ken Liu and Joel Martinsen, and has been translated into over 26 languages worldwide.

**The Story of Three-Body Problem**

During the Cultural Revolution, Ye Wenjie, an astrophysics graduate from Tsinghua University, witnesses her father get beaten to death during a struggle session by Red Guards from Tsinghua High School, who were supported by Ye's mother and younger sister. Ye is officially branded a traitor and is forced to join a labor brigade in Inner Mongolia, where she befriends a government journalist who enlists Ye's help in transcribing a letter to the government. The letter details policy suggestions based on the book Silent Spring, which Ye read. However, the journalist betrays Ye, who is sentenced to prison after the letter is viewed as seditious by the government. In prison, Ye is recruited by Yang Weining and Lei Zhicheng, two military physicists working under Red Coast, a secret Chinese initiative to use high-powered radio waves to damage spy satellites.

Four decades later, Beijing police ask nanotech engineer Wang Miao, along with cunning detective Shi Qiang, to infiltrate a secretive cabal of scientists after a spate of inexplicable suicides, including Ye Wenjie's daughter Yang Dong. Wang's investigation lead to a mysterious online game and immerse him in a virtual world ruled by the intractable and unpredictable interaction of its three suns. While at the same time, they start to notice that the world's governments are communicating closely with each other and have put aside their traditional rivalries to prepare for war.

Earth-Trisolaris Organization

The **Earth-Trisolaris Organization** (ETO) is a human organization dedicated to helping the Trisolarians invade Earth and destroy human civilization. The organization was founded by Ye Wenjie and Mike Evans. The organization has enormous impacts on human society until their goal is exposed. One of the most famous slogans is "destroy human tyranny, the world belongs to Trisolarians." One of its bases is the Second Red Coast Base aboard the ship *Judgment Day*. The organization has attempted to kill Luo Ji several times. However, the organization disintegrated before the Doomsday Battle. The greatest success is that its Wallbreakers succeed in discovering all of the Wallfacers' plans.

## Factions

The members of the ETO fall into three main factions: the Adventists, the Redemptionists, and the Survivors.

### Adventists

The Adventists are a purist faction of the ETO, comprising mainly of believers in Mike Evans's theory of Pan-Species Communism. They do not have high expectations of the Trisolarians and are primarily driven by a hatred of the human race. The Adventists' motto, coined by Mike Evans, is "We don't know what civilization is like, but we know humanity." The ship *Judgment Day* is the core base and command center for the Adventists.

### Redemptionists

The Redemptionists are a religious faction that rose to power some time after the foundation of the ETO, comprising of believers who worship the Trisolarians, believing their civilization is more advanced. They consider Alpha Centauri to be a holy site. They consider their faith to be stronger than other religions because they have proof that Trisolarans exist. In this religion, the believers think they are responsible for saving the Trisolarians, the gods, instead of the other way around. The ultimate mission is to save Trisolarians by solving the three-body problem at the human society's cost, but it's more preferable if the solution enables the Trisolarians to remain within their home system. The members tend to be highly educated. They recruit secretly; they distribute a computer game on a fictionalized world similar to the Trisolarian one in order to spot people susceptible to persuasion.

### Survivors

The Survivors are a faction whose primary goal is to survive the Trisolarian invasion. After the verification of the invading fleet's existence, people on Earth start to scramble for survival, giving birth to this fraction. Members wish that by serving the Trisolarian interests and selling out the human race, they and their offsprings may be granted privileges by the Trisolarian invaders, therefore may survive the war. Their members tend to be from the lower social classes and primarily from Asia, especially China.
The great rip

The great rip is the disaster that destroyed the 191 trisolarian civilisation. Compared to the civilisations before it, they had ample warning of the disaster. Based on surviving records, the astronomers of Civilization 191 detected a frozen flying star early on.

In the great rip, three flying stars froze simultaneously, and then the three suns falling directly toward their world. A few days later, one of the suns moved to a distance where its outer gaseous layer became visible. In the middle of a tranquil night, the star suddenly turned into a blazing sun. Separated by intervals of thirty hours or so, the other two suns also appeared in quick succession.

This was not a normal kind of tri-solar day. By the time the last flying star turned into a sun, the first sun had already swept past the planet at extremely close range. Right after that, the other two suns swept past Trisolaris at even closer ranges, well within the planet’s Roche limit31, such that the tidal forces imposed on Trisolaris by the three suns exceeded the force of the planet’s gravitational self-attraction. The first sun shook the deepest geological structure of the planet; the second sun tore open a great rift in the planet that went straight to the core; and the third sun ripped the planet into two pieces.

The great rip was the most terrible disaster in the entire history of Trisolaris. After the planet was torn apart, the two irregularly shaped pieces each returned to spherical form under self-gravitation. The dense, searing planetary core material gushed to the surface, and the oceans boiled over the lava. The continents drifted over the magma like icebergs. As they collided, the ground became as soft as the ocean. Massive mountain ranges tens of thousands of meters high rose in an hour and disappeared just as quickly.

For a while, the two ripped-apart pieces were still connected by streams of molten lava that coalesced into a space-spanning river. Then the lava cooled and turned into rings around the planets, but because of perturbations from the planets, the rings were unstable. The rocks that formed them fell back to the surface in a rain of giant stones that lasted several centuries.

The ecological destruction caused by this catastrophe was the most severe in all of history. All life on the companion planet went extinct, and the mother planet almost became a lifeless waste as well. But in the end, the seeds of life managed to germinate here, and as the geology of the mother planet settled down, evolution began its tottering steps in new oceans and on new continents, until civilization reappeared for the one hundred and ninety-second time. The entire process took ninety million years.
Thomas Wade

**Thomas Wade** was Chief of the PDC Intelligence Agency (PIA) and one of the candidates to succeed Luo Ji as the next Swordholder.

## Biography

Wade admitted to murdering the PIA Technology Planning Center director, Mikhail Vadimov, who was one of the other Swordholder candidates. Wade later attempted to murder Cheng Xin, also a Sworldholder candidate, by impersonating 艾 AA and arranging a fake meeting. Wade was shot by police during this incident and later imprisoned.

Resource I

Resource I is a space city in the Bunker World. Cheng Xin visted this city in the Death's End. Its length was 120 kilometers, but the diameter was only three kilometers, like a thin stick. It did not spin around the long axis, but rather, tumbled about its center, end over end. The city’s interior was divided into levels, and the gravity at each level differed dramatically. Only a few levels were suitable for living, while the rest were devoted to various industries adapted to the different gravities.
Li Wei

Li Wei is a Captain in the SFJC Combined Fleet and Intermediate EM Weapons System Controller aboard the warship *Wannian Kunpeng*. He collaborated with Zhao Xin to determine that the Trisolaran Droplet was attacking the Combined Fleet during the Doomsday Battle. Li Wei was one of the 60,000 survivors of the Doomsday Battle, having abandoned ship aboard a small spacecraft.
Bill Hines

**Bill Hines** was an English neuroscientist, politician, and Wallfacer. Hines was nominated for Nobel Prizes in Physics and Physiology or Medicine for research he conducted with his colleague and wife, Keiko Yamasuki, regarding quantum brain activity. Later in his career, he served as President of the European Union (EU) for two years.
Dehydration

## Process

Follower stripped off his sweat-soaked robe and lay down nude on the muddy earth. In the last glow from the sun, already below the horizon, Wang saw water oozing out of Follower’s body. He knew that it was no longer sweat. All the water in his body was being discharged and squeezed out. The water coalesced into a few small rivulets in the mud. His body turned soft and lost its shape like a melting candle.

Ten minutes later, all the water had been eliminated from his body. Follower was now a man-shaped piece of leather stretched out on the ground. His facial features had flattened and become indistinct.

Wang remembered seeing such man-shaped pieces of hide scattered along the road. Some were torn and incomplete. He supposed they were the dehydrated bodies Follower spoke of earlier as potential kindling.

The Follower was not dead. He picked up Follower’s skin, brushed the mud and dust off, laid him out on the rock, and rolled him up like a balloon with its air let out. “He’ll recover soon enough, when we soak him in water. It’s just like soaking dried mushrooms.”

Even his bones have turned soft. His skeleton has turned into dried fibers. This makes him easy to carry.

“In this world, can everyone be dehydrated and rehydrated?” “Of course. You can, too. Otherwise we could not survive the Chaotic Eras.” King Wen handed the rolled-up Follower to Wang. “Carry him. If you abandon him on the road, he’ll be burned or eaten.”

Wang accepted the skin, a light roll. He held it under his arm, and it didn’t feel too strange.

Natural Selection (spaceship)

**Natural Selection** is a Stellar-class Warship. The captain of Natural Selection is Dongfang Yanxu. Natural Selection fled Earth before the Droplet arrived. It attempted to initiate a first strike against the other vessels due to the conclusion that there are not supplies among the ships to make the interstellar journey. However, Ultimate Law fired faster and Natural selection was destroyed during the Battle of Darkness.
Chu Yan

Chu Yan is captain of *Blue Space* a Stellar-class Warship of the Asian Fleet. *Blue Space* avoided the Doomsday Battle when it was sent in pursuit of Zhang Beihai and *Natural Selection*. While in pursuit of the ship, humanity lost the Doomsday Battle and all four pursuing ships agreed to join Zhang Beihai and become Starship Earth. Chu Yan made this decision to join the new mission to travel the 18 light years together to NH558J2, a journey that would take approximately 2,000 years.

All five captains realized they did not have enough fuel and supplies this set off the Battle of Darkness where all five captains came to the same conclusion that they would have to kill the other ships' crews and take their supplies. In this case it was Ultimate Law that acted first firing H-bombs at all ships to use infrasonic weapons to kill all the crews and leave the ships intact. However, Chu Yan coming to the same conclusion as the other captains, but he chose a defensive tactic and instead operated *Blue Space* in a vacuum, with the crew in suits. This allowed the ship to survive the infrasonic attack which required air to kill the crew, *Blue Space* counterattacked *Ultimate Law*. Thus Chu Yan, his crew, and *Blue Space* became the soul survivor of Starship Earth and continued on their journey as a seed of humanity in the universe.
Three Body Problem Chapter 7

Wang Miao gets a haptic suit and enters the game (www.threebody.com), using the ID hairen (海人).

In the game, the setting was the Warring States Period, and Wang meets King Wen of Zhou. He learns that King Zhou of Shang is also alive.

They say they are in the midst of a Chaotic Era. King Wen says he needs to make it to Zhaoge.

The game sped up the progress of time. A month in game time might pass in half an hour. This made the journey through the Chaotic Era at least tolerable for Wang.

Civilization Number 137 perished, having reached the Warring States Period.

## Characters

* Wang Miao
* Ding Yi
* King Wen of Zhou

Mycenae (Spaceship)

Mycenae is a midsized planetary ship in the Bunker Era without an ecological cycling system. After leaving the Solar System, a passenger would not last five years, even if all the ship’s supplies were used to sustain only them. The AI of Halo introduced it to AA and Cheng Xin when the solar system was two-dimensionizing. The ship has been two-dimensionized later, too.
Ruan Wen

Professor Ruan Wen (阮雯) is Ye Wenjie's closest friend. Ruan studied at Cambridge and was interested in European art and music. Ruan was tortured (high heels placed around her neck and lipstick streaked across her face) by Red Guards for living the 'corrupt lifestyle of a capitalist'.

## Trivia

* Ruan 阮 corresponds to the Vietnamese surname Nguyen
Ivan Antonov

Ivan Antonov is one of the candidates competing to succeed Luo Ji in the Swordholder position. He was a Russian and the next youngest of the candidates, at forty-three years old. He had an impressive résumé: Once the youngest vice-admiral in the Russian Navy, he later became the deputy commander of the Baltic Fleet. He had entered hibernation because of a terminal illness. He join the Resistance during the Great Resettlement as one of the commander and is one of those who survive.
Alaska (Spaceship)

Alaska is one of the spaceships in the Bunker Era and was sent to investigate the dual-vector foil sent to the solar system. It was equipped with gravitational wave reception systems and could form a positioning network to determine the location of the transmission source with precision at close range. It approached the dual-vector foil (packaged two-dimensional foil) and observed it for a few days and then left it under the advice of 白Ice. However, it cannot reach the escape velocity of the dual-vector foil and was two-dimensionalized.
Shao Lin

Shao Lin (绍琳) is Ye Zhetai's wife. During the Cultural Revolution, she accuses her husband of teaching Einstein's theory of relativity, which she labels as a 'capitalist' theory. She also accuses Einstein of being a money grabber and going to the capitalist USA.

Shao Lin called Ohm's law the resistance law, Maxwell's equations the electromagnetic equations, and Planck's constant the quantum constant. She also said that all scientific accomplishments result from the contributions of the working masses. She criticizes Ye Zhetai for teaching the 'reactionary' Copenhagen interpretation of quantum mechanics.

She was also a physicist and once taught a class in a qipao.

But even as a communist fanatic, she did not have the status to carry the Little Red Book. She could not hide the 'fault' that she was born into a family of intellectuals. Her father spoke German and accompanied Einstein when he visited Shanghai in 1922. Moreover, her father studied physics because of Einstein.

Her father accompanied Einstein on Nanjing Road at Shanghai University alongside Yu Youren and Cao Gubing. There Einstein saw a workerboy who made 5 cents a day.

Starship Earth

Starship Earth was the group of five stellar-class warships that were led by Zhang Beihai and had fled the solar system after the Doomsday Battle. Four vessels were sent in pursuit of Zhang Beihai and the ship *Natural Selection* which he had taken over. The pursuing vessels were the two Asian Fleet Vessels *Blue Space* and *Deep Space*, the European Fleet Vessel *Ultimate Law*, and the *Enterprise* of the North American Fleet. The four pursuing vessels joined Zhang Beihai after the defeat of humanity at the Doomsday Battle.

The group of five spaceships named themselves Starship Earth since they believed they may be the last surviving group of humanity's civilization. They made for the star NH558J2, which had two confirmed gaseous planets which they could use to refuel the ships and was 18 light years away. This voyage would at their present speed would take 2,000 years to make. They hoped to refuel there and head to another destination just 1.5 light years from there where they was a possible Earth-like planet.

The dire reality of the length of travel in both years and supply requirements led each captain of the five vessels to realize there were not enough supplies for the five ships and their crew to make the destination. They all came to the realization that they would have to kill the crew of the others in order to survive and reach their destination. Zhang Beihei and Dongfang Yanxu believed they were the first to reach this conclusion but the Battle of Darkness was actually begun by *Ultimate Law* which had come to the conclusion but a minute earlier. The crew of Natural Selection, Deep Space, and Enterprise were all killed instantly, but Blue Space also having come to the same conclusion prepared for the battle. They were operating in a vacuum with the crew in suits to survive the possibility of an H-bomb, *Blue Space* then destroyed *Ultimate Law* with laser weapons. Leaving the ship as the sole survivor of Starship Earth.

*Blue Space* used the remains of the three intact vessels to set up a monument in the form of a tomb that would remain in space for 50,000 years. After this, *Blue Space* continued on its way to NH558J2.

Droplets

Droplets are small, extremely maneuverable, and extremely resilient unmanned spaceships. Created by the Trisolarans, the droplets were presumably deployed from the larger Trisolaran world ships, and reached earth before any other Trisolaran ships could.

The outer shell of a droplet seems to be coated in advanced Trisolaran technology, which allows strong interaction to hold the ship together, making it extremely durable.

One such droplet was intercepted by the Human fleet. Originally thought as a peace offering/gift of goodwill, this single droplet was able to annihilate most of the Human fleet by ramming through their fuel cells during the Doomsday Battle. It destroyed nearly 1,000 Stellar-class Warships in a matter of 15 minutes. Later two droplets accompany *Gravit*y in chasing the breakaway *Blue Space*, but then attack *Gravity*, after the Deterrence Era ends. Shortly after this attack the Broadcast Era began.
A Fairy Tale of Yangtze

A Fairy Tale of Yangtze Is a movie holographic movie AA played for Cheng Xin. The movie had won Best Picture at that year’s Oscars. It was based on a song composed in busuanzi verse form by the Song Dynasty poet Li Zhiyi.

The film was set in some unspecified ancient golden age, and told the story of a pair of lovers, one who lived at the source of the Yangtze, and the other at its mouth. The pair was kept apart for the entire film; they never got to see each other, not even in an imaginary scene. But their love was portrayed with utter sorrow and pathos. The cinematography was wonderful: The elegance and refinement of the lower Yangtze Delta and the vigor and strength of the Tibetan Plateau contrasted and complemented each other, forming an intoxicating mix. However, this is one of the movie the trisolarian sent to Earth.
N-body problem

The Three Body Problem is a physics and mathematics problem arising in the field of celestial mechanics and astronomy. The question is to predict the spacetime trajectories of three (point) masses under the influence of Newtonian gravity (inverse square law). This problem is currently unsolved for all but simple cases. No closed form solution is known in general, but progress has been made using computer simulations. The intractable part arises from the unpredictability of the chaotic dynamics induced by three bodies.

Taking into account general relativity makes the problem significantly harder.

By contrast, the two body problem of classical physics is completely solved.

## Newtonian gravity

.

The 2-body problem (

{\displaystyle i = 1,2}

) has a closed form solution (and has an elegant form via change of coordinates and center of mass).

The 3-body problem (

,
3

{\displaystyle i = 1, 2, 3}

) has no closed form solution in general (only for special cases). It exhibits chaotic behavior and sensitivity to initial values fed into the above differential equations. This is sometimes called the butterfly effect.

The n-body problem (

n
≥
3

{\displaystyle n \ge 3}

) also has no general closed form solution.

## Notes

* The lack of a closed form solution and chaotic behavior is why three-body systems are hard to predict. King Wen of Zhou (Three Body) fails to predict the exact arrivals of the chaotic era and stable era in the Three Body (game).
Blue Space

*Blue Space* is a Stellar-class Warship of the Asian Fleet that was sent in pursuit of *Natural Selection* after that vessel fled the solar system fearing that Earth would not win the Doomsday Battle with Trisolaris. When this in fact became reality the incredulous captains now followed Zhang Beihai and *Natural Selection* and the five vessels formed to become Starship Earth. This new mission sought to settle in a new star system at NH558J2 which was 18 light years away. Based on the stellar-class ship's top speed this meant it would take 2,000 years to reach the new star system. At nearly the same time the five captains of Starship Earth realized that they did not individually have enough fuel and supplies to reach NH558J2 and this led to the Battle of Darkness. In this battle
