3 Body Problem

The Three-Body Problem
Astronomer Ye Wenjie is brought to the military's top-secret Red Coast Project after suffering an attack during the Cultural Revolution. She achieves a significant advancement in the search for extraterrestrial civilization when she uses the Sun as an amplifier to send the first sounds of Earth's civilization into space. Meanwhile, the planet Trisolaris, located four light years distant and dominated by the chaotic orbits of its three suns, experiences ever-recurring destruction and rebirth, thus forcing the planet's inhabitants to flee their home planet. As they prepare their exodus, Ye Wenjie, despairing of humanity's ability to save itself from itself, exposes the coordinates of the Earth to the Trisolarans, completely changing the fates of both worlds.

When anomalies begin to disrupt the ability of Earth's scientists to conduct fundamental research, nanomaterials researcher Wang Miao plays the mysterious online game "Three-Body Problem" and starts to explore the nature of the game's world. Wang Miao meets the secretive Earth-Trisolaris Organization (ETO), created to support the impending arrival of Trisolarans, while attending a player meeting. "Operations Guzheng" allows the Operations Centre to partially defeat the Adventists (who want the Trisolarans to wipe out humanity) and the Redemptionists (who seek to help the Trisolarans find a computational solution to the three-body problem plaguing Trisolaris). It also reveals that the Trisolarans have launched their invasion of Earth in search of a stable place to live. The end of humanity draws near as the huge Trisolaran fleet approaches Earth after using their superior technology to shut down Earth's advances in fundamental science.
