The aliens—the San-Ti (Tri-solarans)—live in a chaotic solar system with three suns. Their planet is subject to random, apocalyptic "Chaotic Eras" where they are burned or frozen alive. They are desperate to leave. Earth is their paradise.

But what is 3 Body Problem actually about ? Is it just hard science for geniuses, or is it a character drama wrapped in cosmic horror?

The suns move unpredictably. Sometimes they rise all at once and scorch the planet. Sometimes they all set and freeze it. The humanoid inhabitants "dehydrate" into flat sheets of paper to survive the chaos.

The goal of the game? Figure out the physics of the three-body problem—predicting the motion of three gravitational bodies. It is a math problem that has stumped humanity for centuries (literally, Newton couldn’t solve it).

But the problem of the story is deeply human. "Civilization is a fleeting spark in the dark forest of the universe." — The Dark Forest Theory The trilogy introduces the "Dark Forest" theory: The universe is a dark forest. Every civilization is a hunter creeping through the trees. If you see another civilization, you have one option: kill them before they kill you. Because you cannot know their intentions.

If you’ve scrolled through Netflix recently or walked past a bookstore in the last decade, you’ve seen the symbol: three body, three suns. You might have heard the hype about Game of Thrones creators David Benioff and D.B. Weiss teaming up with Alexander Woo to adapt the "unadaptable."

And if they find us?
