Major events across the Three-Body trilogy.
A chronological overview of the most important events in the Three-Body universe.
Zhang Beihai recruited a crew of true believers, seized the Natural Selection at the moment he judged the fleet was doomed, and accelerated away from humanity's last battle. A detailed reconstruction of the mutiny, the man behind it, and the trial that followed.
A breakdown of the Wallfacer project — why it was created, what each Wallfacer's secret strategy was, and how the program ultimately played out against the Trisolarans.
For every Wallfacer concealing a secret strategy, the Trisolarans cultivated a Wallbreaker — a human agent tasked with psychologically exposing them. An examination of how the Wallbreaker program worked, which Wallfacers were broken and how, and what it reveals about Trisolaran intelligence operations on Earth.
How governments coordinated the announcement of the Trisolaran threat, the immediate societal reaction, and the psychological and political shockwave of a species confronting its first confirmed contact with intelligent life under the worst possible circumstances.
Major events across the Three-Body trilogy.
An overview of the Great Ravine — the catastrophic period of famine, collapse, and population reduction that struck Earth during the early Deterrence Era as resources were poured into the crisis response.
After Luo Ji established Dark Forest deterrence, someone had to hold the trigger. An examination of the Swordholder institution: how candidates were selected, why Cheng Xin was chosen over Thomas Wade, and the profound irony that the qualities that make a person humane may be precisely what makes them unfit to keep a civilization alive.
A detailed reconstruction of the two-dimensional foil attack on the solar system — what happened, in what order, who survived, and why this sequence is considered one of the most haunting passages in science fiction.
After the two-dimensional foil consumed the solar system, what remained of human memory was scattered across the galaxy. A look at the fate of Earth in the trilogy's closing chapters.
Among the most devastating acts of the Earth-Trisolaris Organization was the Sagan File — a comprehensive dossier on humanity's military capabilities, political vulnerabilities, and psychological weaknesses transmitted directly to the approaching Trisolaran fleet.
After the two-dimensional foil destroyed the solar system, humanity entered the Roaming Era — a period of interstellar nomadism with no home planet, no fixed civilization, and no clear destination.
Hidden in the mountains of Inner Mongolia, Red Coast Base was China's secret SETI installation — and the place where Ye Wenjie received a reply from the stars.
When humanity learned of the Trisolaran threat, it created an unprecedented global institution — the Planetary Defense Council — to coordinate a response across centuries. A look at how the PDC was structured, how it wielded power over national governments, and the impossible political challenge of maintaining institutional coherence across generations for a war four hundred years away.
When humanity learned an alien fleet was four centuries away, the immediate practical problem was governance. The Planetary Defense Council was the answer — and its compromises reveal as much as its ambitions.
The Three-Body Problem opens not in space but in the chaos of the Cultural Revolution — a deliberate choice that roots the entire trilogy in Chinese historical trauma. An examination of how the violence Ye Wenjie witnesses shapes her fateful decision, and why Liu Cixin's framing through twentieth-century Chinese history gives the Dark Forest theory a human weight absent from most Western science fiction.
Key developments in humanity's response to cosmic threats.
How the Crisis Era's military shipbuilding program triggered a humanitarian catastrophe that killed billions — and what it means that humanity made that choice.
Before the Wallfacers and the fleet battles, humanity passed through the Great Ravine — a period of catastrophic ecological and social breakdown triggered by the knowledge of the Trisolaran threat.
The story of the two starships that broke away from the human fleet, discovered a Trisolaran probe, and made a decision that changed the balance of cosmic power — and whether they were right.
By the closing chapters of Death's End, human civilization has dispersed across the galaxy in curvature-drive ships, becoming one small voice among countless others in the cosmic dark. An overview of the Galaxy Era.
Before Wang Miao or the police knew what they were looking for, the answer was hiding in plain sight inside a prestigious international research organization. A look at how the Frontiers of Science served as the ETO's most effective recruitment pipeline.
Events leading to humanity's first contact with an alien civilization.
The Earth-Trisolaris Organization didn't recruit from the margins — it drew from the top of human society. An examination of how the ETO built and maintained a global clandestine network across decades.
When civilization seemed doomed, a faction of humanity quietly prepared a fleet to flee into deep space rather than fight. An examination of the Escapist movement — its moral logic, its secret preparations, and how the rest of humanity reacted.
Throughout the Crisis Era, the Escapist movement asked an uncomfortable question: why stay and fight when you could run? An examination of the movement's moral logic, how governments suppressed it, and whether history vindicated those who wanted to flee.
Two centuries of shipbuilding. Thousands of warships. Destroyed in hours by two alien probes the size of a car. A reconstruction of the Doomsday Battle and what it meant for everything that followed.
Centuries of living under the shadow of mutual annihilation reshaped human culture, politics, and values in profound ways. A look at the social world of the Deterrence Era — its unusual freedoms, its strange complacencies, and why it produced both the best and worst instincts of the species.
Under the umbrella of Dark Forest deterrence, humanity entered a period of unprecedented stability — and unprecedented denial. An examination of what daily life looked like during the Deterrence Era's strange, borrowed golden age.
When Luo Ji broadcast Trisolaris's coordinates, the planet's fate was sealed. A reconstruction of how and when Trisolaris was destroyed, what the Trisolarans knew in their final hours, and the moral weight of a civilization's extinction — even one that threatened our own.
When humanity learned that an alien fleet would arrive in four centuries, it fundamentally changed how civilization organized itself. A survey of the Crisis Era's political institutions, cultural shifts, technological priorities, and the strange psychological tension of preparing for a war no living person would survive to see.
As the Crisis Era unfolded across decades, humanity's response fragmented into competing philosophical camps — Escapists, Survivors, and every shade in between — each offering a different answer to what it meant to endure a four-hundred-year countdown.
When the solar system was exposed to the universe, humanity fled behind gas giants. A look at the Bunker Project — its engineering ambition, social upheaval, and ultimate futility.
After deterrence collapsed and the two-dimensional foil began consuming the solar system, surviving humanity attempted one final refuge: clustering settlements in the gravitational shadow of gas giants, shielded from the dimensional attack.
After the Battle of Darkness, the crew of the Bronze Age returned to face judgment for the atrocities they committed to survive. An examination of the trial and the impossible question it posed: how do you hold people accountable for doing exactly what the universe demanded?
Centuries into their voyage, the crew of the Blue Space faced resource collapse so severe that survival required acts the ship's founders could never have imagined — and later, the discovery of a dark matter map hidden inside a Trisolaran probe that changed everything they thought they knew about the universe.
A timeline breakdown of the engagement at the edge of the solar system — how a single Droplet probe dismantled the combined human fleet and what it meant for Earth's future.
Centuries into deep space, the human fleet meant to fight the Trisolarans turned on itself instead — a brutal engagement where ships annihilated each other to eliminate witnesses and preserve resources. An examination of the Battle of Darkness and the chilling logic that made it inevitable.
Long before the solar system was attacked, 647 stellar destructions — too precise to be natural — provided the first empirical evidence that the Dark Forest theory wasn't just sociology but observable fact.
When a star in Cygnus vanished in an event matching no known astrophysical process, it confirmed that Luo Ji's deterrence theory was real — and that the universe was far more dangerous than anyone had dared believe.
