''The Three-Body Problem'' () is a science fiction novel written by the Chinese writer Liu Cixin. The title refers to the three-body problem in orbital mechanics. It is the first novel of the ''Remembrance of Earth's Past'' () trilogy, but the whole series is often referred to as ''The Three-Body Problem''. The trilogy's second and third novels are '' The Dark Forest'' and ''Death's End,'' respectively.

The first volume of ''The Three-Body Problem'' was originally serialized in ''Science Fiction World'' in 2006 and published as a standalone book in 2008, becoming one of the most successful Chinese science fiction novels of the last two decades. The novel received the Chinese Science Fiction Yinhe (" Galaxy") Award in 2006Clute, John

The series portrays a fictional past, present and future where, in the first book, Earth encounters an alien civilisation in a nearby star system that consists of three solar-type stars orbiting each other in an unstable three-body system.

Background

The author, Liu Cixin, was born in Beijing in June 1963. He was an engineer before writing science fiction. In 1989 he wrote ''Supernova Era'' and ''China 2185'', but neither book were published at that time. Liu's first published short story, ''Whalesong'', was published in ''Science Fiction World'' in June 1999. In the same year his novel ''With Her Eyes'' won the Galaxy Award. In 2000 he wrote ''The Wandering Earth'' and received the Galaxy Award again. The Wandering Earth was adapted into a film in 2019. When the short story ''Mountain'' appeared in January 2006, many readers wrote that they hoped he would write a novel. Therefore, he decided to concentrate on novel-length texts rather than on short stories. The other two famous novels besides ''The Three-Body Problem'' series are ''Supernova Era'' and ''Ball Lightning''. When he was not otherwise busy, he wrote three to five thousand words a day, and each of his books took about one year to complete.

English translation

In 2012, Chinese-American science-fiction author Ken Liu and translator Joel Martinsen were commissioned by the China Educational Publications Import and Export Corporation (CEPIEC) to produce an English translation of ''The Three-Body Problem'', with Liu translating the first and last volumes, and Martinsen translating the second volume''.'' In 2013, it was announced that the series would be published by Tor in the United States, and by Head of Zeus in the United Kingdom.

Liu and Martinsen's translation of the novels contains footnotes explaining references to Chinese history that may be unfamiliar to international audiences. There are also some changes in the order of the chapters for the first volume. In the translated version chapters which take place during the Cultural Revolution appear at the beginning of the novel, rather than in middle, as they were serialized in 2006 and also as they appeared in the standalone version of the novel published in 2008. According to the author, these chapters had originally been intended as the opening, but were moved by his publishers to avoid attracting the attention of government censors.

Plot

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.

After working with them for some time, she learns that the stated purpose is a front for Red Coast's true intention: the search for extraterrestrial life. Ye discovers the possibility of amplifying outgoing radio waves by using microwave cavities within the sun and sends an interstellar message. Eight years later, now in a loveless marriage with Yang, Ye receives a message from a concerned alien pacifist from the planet Trisolaris, warning her not to respond or else the inhabitants of Trisolaris will find and invade Earth. The alien describes Trisolaris's environmental conditions and societal history. Disillusioned by the political chaos and having come to despise humankind, Ye responds anyway, inviting them to come to Earth to settle its problems. She murders Yang and Lei to keep the alien message secret.

Some time later, with the end of the Cultural Revolution and Ye's return to Tsinghua as a professor, Ye encounters Mike Evans, a hermit and the son of the CEO of the world's largest oil company. Evans is also a radical environmentalist and antispeciesist. Seeing that Evans is direly angry at humanity as well, Ye confides in him and tells him about the events at Red Coast. Evans uses his inherited financial power to hire men and purchases a giant ship – Judgement Day – which he converts into a mobile colony and listening post. Upon receiving messages from Trisolaris, validating Ye's story, Evans announces the creation of the militant and semi-secret Earth-Trisolaris Organization (ETO) as a fifth column for Trisolaris and appoints Ye its leader. According to the messages, the Trisolaran invasion force has departed, but will not reach Earth for 450 years.

The society attracts numerous scientists, minor government officials, and other educated people who are disappointed with world affairs. They assemble a private army and build small nuclear weapons. However, Evans retains control of most resources and starts to alter and withhold alien messages from Ye and others. Furthermore, the society splits into factions, with the Adventists (led by Evans) seeking complete destruction of humanity by the Trisolarans, and the Redemptionists (led by Shen Yufei) seeking to help the Trisolarans to find a computational solution to the three-body problem, which plagues their planet. A third, smaller faction, the Survivors, intend to help the Trisolarans in exchange for their own descendants' lives while the rest of humanity dies.

In the present day, Wang Miao, a nanotechnology professor, is asked to work with Shi Qiang, a cunning detective, to investigate the mysterious deaths of several scientists, including Ye Wenjie's daughter Yang Dong. The two of them notice that the world's governments are communicating closely with each other and have put aside their traditional rivalries to prepare for war. Over the next few days, Wang experiences strange hallucinations and meets with Ye. Wang sees people playing a sophisticated virtual-reality video game called ''Three Body'' (which was created by the ETO as a recruitment tool) and begins to play himself. The game portrays a planet whose climate randomly flips between Stable and Chaotic Eras. During Chaotic Eras, the weather oscillates unpredictably between extreme cold and extreme heat, sometimes within minutes.

The inhabitants (who are represented as having human bodies) seek ways to predict Chaotic Eras so they can better survive. Unlike humans, they have evolved the special ability to 'dehydrate', turning themselves into a roll of canvas. They do this in order to lie dormant when the Chaotic Eras occur, requiring another person to rehydrate them. Characters resembling Aristotle, Mozi, Newton, and others try and fail to model the climate as multiple civilizations grow and are wiped out by large-scale disasters. Wang wins acclaim by figuring out how the climate works: (1) the planet Trisolaris has three suns; (2) the suns have different kinds of compositions, and when they are far away from the planet's surface only the core of the sun can penetrate to the surface, appearing in the sky as a flying star; (3) Stable Eras occur when two suns are far away and Trisolaris orbits the third; (4) Chaotic Eras occur when Trisolaris is pulled by more than one sun; (5) firestorms happen when two or three suns are close to the planet's surface; (6) three flying stars causes intense cold because it means all three suns are far away; and (7) eventually the three suns will align and Trisolaris will plunge into the nearest one and be consumed. The game shows the Trisolarans building and launching colony ships to invade Earth, believing that the stable orbit will allow unprecedented prosperity and let them escape the destruction of their planet.

Wang is inducted into the ETO, and informs Shi of one of their meetings. This leads to a battle between the PLA and the society's soldiers, as well as Ye's arrest. The PLA works with the Americans, led by Colonel Stanton, to ambush Judgement Day as it passes through the Panama Canal. To prevent the crew from destroying their communications with the Trisolarans, the team follows Shi's suggestion to use Wang's nano-material filament in a fence to quickly cut the ship apart and kill everyone aboard. However, documents and computers cut by the filament could be reassembled after. Some revelations emerge from the Trisolaran communications: (1) The aliens have extremely advanced picotechnology that allows them to create 11-dimensional supercomputers called sophons which, when viewed in three dimensions, occupy the volume of a proton. (2) Two of these sophons have been laboriously manufactured and sent to Earth, having the power to cause hallucinations, spy on any corner of the Earth, transmit the information gathered to Trisolaris using quantum entanglement, and disrupt all of Earth's particle accelerators. The Trisolarans fear humanity will develop technology advanced enough to fight off the invasion, and decide that disrupting the accelerators to give random results will paralyze Earth's technological advancement until the Trisolarans arrive.

Once several sophons have arrived, they plan to fabricate visual miracles and other hallucinations on a massive scale to make humanity distrust its own scientists. The Trisolarans detect humanity's revelation via sophons and beam to the eyes of the PLA one final message, "You're bugs!", then cease all communications. Now in custody, Ye is allowed to visit the old Red Coast base, and reflects upon her past choices, noting that humanity from now on will never be the same. Shi Qiang finds Wang Miao and his colleagues in a depressed drinking binge, and sobers them up by driving them to his hometown village in Northeastern China. Shi reflects on how despite all the advances humanity has made with pesticides, the simple-minded locust still manages to survive and thrive. With renewed hope, Wang and Shi return to Beijing to help plan the war against the Trisolarans.

Inspiration

Liu Cixin was born in 1963. When he was 3 years old, his family moved from the Beijing Coal Design Institute to Yangquan in Shanxi Province due to his father's job change. He also spent part of his childhood in the countryside of his ancestral hometown Luoshan County, Henan Province. April 25, 1970, was a pivotal moment for Liu. Looking back on his science-fiction journey, he recalls the day when China's first satellite, Dong Fang Hong 1, was launched, and as he stood by the pond looking up at the starry sky, he felt an indefinable sense of longing.

A few years later, one summer evening, Liu Cixin found an entire box of books under his bed in his home in Yangquan, there was an anthology of Tolstoy, ''Moby-Dick'', Jules Verne's ''Journey to the Center of the Earth'', and Rachel Carson’s ''Silent Spring''. The first book he read was ''Journey to the Center of the Earth'', about which his father told him: "It's called science fiction, it's a creative writing based on science". This was his first encounter with science fiction: "My persistence stems from the words of my father". At that time, these books could only be read privately by individuals; "I felt like being alone on an island, is a very lonely state".

The reverence, or even fear, of the Universe, is one of the main prompting force of Liu's writing. According to him, as humans, we will stand in awe of the scale and depth of the universe. His novels also focus on the curiosity of the unknown. Liu Cixin says he cannot help thinking about the future world and lifestyle of human beings, and he tries to invoke readers’ curiosity with his books. He also believes that the humans should be treated as an entirety.

Awards

Reception

In December 2019, ''The New York Times'' cited ''The Three-Body Problem'' as having helped to popularize Chinese science fiction internationally, crediting the quality of Ken Liu's English translation, as well as endorsements of the book by George R. R. Martin, Facebook founder Mark Zuckerberg, and former U.S. president Barack Obama. George R. R. Martin wrote a blog about the novel, personally expressing its worthiness of the Hugo Award. Obama said the book had "immense" scope, and that it was "fun to read, partly because my day-to-day problems with Congress seem fairly petty".

'' Kirkus Reviews'' wrote that "in concept and development, it resembles top-notch Arthur C. Clarke or Larry Niven but with a perspective—plots, mysteries, conspiracies, murders, revelations and all—embedded in a culture and politic dramatically unfamiliar to most readers in the West, conveniently illuminated with footnotes courtesy of translator Liu." Joshua Rothman of ''The New Yorker'' also called Liu Cixin "China's Arthur C. Clarke", and similarly observed that in "American science fiction ... humanity's imagined future often looks a lot like America’s past. For an American reader, one of the pleasures of reading Liu is that his stories draw on entirely different resources", citing his use of themes relating to Chinese history and politics.

Matthew A. Morrison writes that the novel can "evoke a response all but unique to the genre: an awe at nature and the universe SF readers call a 'sense of wonder'." Due to the novels' groundbreaking success and reception, Netflix announced in 2020 that Game of Thrones writers David Benioff and D. B. Weiss are adapting the series into a sci-fi tv drama.

Also, some Chinese scholars found that the Western readers appreciate the zero-moral universe depicted in the trilogy of The Three Body Problems, which is considered to promote rationalism. Liu Cixin tries to answer the existential dilemma of "where should mankind go from here" through various efforts.
