The Three-Body Problem: Review, Game Theory, Space & Aliens

Rating

3.5/5

A week ago, I finished the first book in the three-part series, The Three-Body Problem. It took me about a month to get through. Some of it was a slog, but parts of it were extremely interesting. Toward the end, the book finally dove into the core of the story, and that was what got me hooked enough to start the second book.

Spoilers Ahead

The Three-Body Problem is a sci-fi novel about humanity’s hypothetical discovery of extraterrestrial life through a Chinese government and military radio facility called Red Coast Base. But before the book becomes a story about aliens, it begins as a story about political trauma, ideology, and the destruction of trust in humanity.

The story opens during the Cultural Revolution, a period when intellectuals, scholars, teachers, and scientists were often scapegoated as enemies of the state. Ye Wenjie’s parents were both highly educated, and her father, Ye Zhetai, was a physicist. During a public struggle session, he is beaten to death by Red Guards after refusing to renounce scientific ideas that were labeled counter-revolutionary, bourgeois, reactionary, or Western.

That part of the story resonated with me because my family suffered under similar historical forces. Growing up, my grandma told me stories about how our family had been part of the doctor community in Shanghai. They owned mansions, were written about in newspapers, and had built a life through education and professional status. Then the Communist Party seized their fortune. One story that always stayed with me was my grandma seeing her aunt beheaded in their home when she was a child. Afterward, the family’s assets were taken.

That history made Ye Wenjie’s disillusionment feel more real to me. In the book, she watches her father get murdered in public by people who claim to be acting in the name of historical progress. Years later, when she confronts the women who killed him, there is no clean moral resolution. They explain that even they suffered after the revolutionary chaos. Once the state had mobilized young radicals and factional violence had spiraled, many of those same revolutionaries were later sent away to the countryside for hard labor. One of them even lost an arm during factional fighting.

That scene stood out because it shows how ideology turns people into instruments. The Red Guards believed they were fighting for the Cultural Revolution and the Maoist regime, but many of them were also being used as pawns in a larger political game. They destroyed lives, but they were also consumed by the same system that radicalized them. The result is not a clean story of villains and victims. It is a story about how political systems can corrupt people, destroy knowledge, and leave everyone permanently damaged.

When I see governments encourage radicalism, or when I see political groups become more divided and less peaceful, it reminds me of the Cultural Revolution. Not because every modern conflict is the same, but because the underlying human psychology feels familiar. Beliefs are rarely formed in isolation. They are shaped by our individual experiences, the groups we identify with, the institutions we trust, and, in the modern technological age, the algorithms that decide what information we repeatedly see.

This divisive psychology becomes a recurring theme throughout The Three-Body Problem. When the first Trisolaran receives Ye Wenjie’s message, he warns her not to respond. He understands that if Earth answers, Trisolaris will locate humanity and eventually dominate it. His warning is an act of sympathy across civilizations. But Ye Wenjie responds anyway. Her decision is not purely logical, and it is not simply evil. It comes from trauma, despair, and her belief that human civilization has already failed its own moral test.

Once the Trisolarans learn about human civilization, they begin their journey across space. The catch is that it will take them 400 years to reach Earth. During that window, they realize humanity may continue advancing fast enough to make their invasion impossible. Humans are technologically weaker in the present, but their scientific progress is dangerous because it compounds. Given 400 years, humanity may develop the ability to stop the Trisolaran fleet before it ever reaches Earth.

The solution is a technology called sophons. Sophons are protons that the Trisolarans unfold into higher dimensions, transform into supercomputers, and send to Earth. Their purpose is not to destroy humanity directly. Their purpose is to attack humanity’s scientific infrastructure. By interfering with particle physics experiments, the sophons corrupt humanity’s ability to verify truth through science. The goal is simple: inhibit scientific advancement and freeze humanity’s technological growth before it becomes a threat.

Ye Wenjie’s defection is caused by trauma, but in game theory terms, it also happens because the board she thought she was playing collapses. She loses trust in humanity. The Cultural Revolution teaches her that truth can be punished, science can be treated as ideology, innocent people can be publicly destroyed, groups can become morally insane, institutions can reward cruelty, and the future may not be better just because history is “moving forward.” Her payoff function changes. Protecting humanity is no longer obviously the highest-value move because she no longer believes humanity deserves to govern itself.

On the Trisolaran side, the listener who warns Ye Wenjie not to respond is also a kind of defector. He acts against the strategic interest of his own civilization because he feels sympathy for humanity. That parallel matters. In both civilizations, there are individuals whose beliefs do not align with the survival goals of the larger group. A civilization may look unified from the outside, but internally it is always made of people with different incentives, traumas, moral beliefs, and breaking points.

The book made me reflect on the idea that truth is the ultimate glue of society. In the age of information, power belongs not only to those who possess knowledge, but to those who can control how truth is discovered, framed, distorted, or broken. That becomes even more important in the age of AI. If AI systems are trained on corrupted data, biased incentives, or hidden agendas, they can distort the shared reality that people depend on to make decisions. Once a society loses its ability to coordinate around truth, individuals lose sight of their role in the larger game, institutions begin to decay, and payoff functions deteriorate. In that sense, The Three-Body Problem is not just about aliens attacking humanity. It is about what happens when the systems we rely on to understand reality can no longer be trusted.
