The Three-Body Problem

by

Liu Cixin

A sophon is a super-computer contained in a proton (hence the name, which combines the word proton with the word “sophia,” the Latin word for wisdom). After a complex process of trial and error, the Trisolarans were able to unfold a 9-dimensional proton into two dimensions, program it with incredible amounts of data, and refold it. The Trisolarans then sent the sophons to earth, where these tiny particles could enter into laboratories and confuse humans’ experimental results, therefore stalling all scientific progress. The sophons are also intelligent enough to report back all information on earth to Trisolaris, effectively meaning that humans are constantly being surveilled by the Trisolarans.

Chapter 33 Quotes

“Even in nature, the destruction of universes must be happening at every second—for example, through the decay of neutrons. Also, a high energy cosmic ray entering the atmosphere may destroy thousands of such miniature universes…You're not feeling sentimental because of this, are you?”

“You amuse me. I will immediately notify the propaganda console and direct him to repeatedly publicize the scientific fact to the world. The people of Trisolaris must understand that the destruction of civilizations is a common occurrence that happens every second of every hour.”
