China's Cixin Liu's The Three-Body Problem (image above) is a stunning science-fiction novel that asks one of the oldest questions in SF: What would it mean for the human race to come in contact with an extraterrestrial intelligence? One of the main characters is a nanotech engineer, who's been swept up in a virtual-reality, online video game called "Three Body" that's so deeply metaphysical, it resembles a cult. When the story reaches its climax, it's unveiled a conspiracy that spans solar systems — one that not only threatens to alter the human race, but the very building blocks of physics that the human species has evolved to understand.
In our real world, The famous three-body problem can be traced back to Isaac Newton in 1680s, thereafter Lagrange, Euler, and Poincare. Studies on the three-body problem leaded to the discovery of the so-called sensitivity dependence of initial condition (SDIC) of chaotic dynamic system.
Chaotic dynamics is widely regarded as the third great scientific revolution in physics in 20th century, comparable to the relativity and the quantum mechanics. Thus, the studies on three-body problem have very important scientific meanings.

Poincare in 1890 revealed that trajectories of three-body systems are commonly ...
