Gravitational waves were one of the settings and plots in Liu Cixin's science fiction novel, The Three Bodies. It described the existence of gravitational waves and its impact on the universe. Gravitational waves were described as follows: "Gravitational waves are an extremely small gravitational disturbance. When two objects with large masses approach each other, the gravitational force generated by them will cancel each other out, resulting in a small acceleration. Gravitational waves are these tiny disturbances that travel at the speed of light and have an instant effect on objects in the universe." " The Three-Body Civilization used gravitational waves to detect other civilizations in the universe and used the characteristics of gravitational waves to establish a communication method that can penetrate the universe." The part of the novel describing gravitational waves happened in the second book, Dark Forest. The general content was as follows: "In order to escape from the Three-Body Civilization, humans had to build a huge antenna to receive the signals of the Three-Body Civilization. The antenna has received the gravitational wave signal sent by the Three-Body Civilization. Humans have used this signal to establish a communication method that can penetrate the universe and contact other civilizations." It should be noted that the description of gravitational waves is not the most detailed part of the novel, but this description is one of the earliest descriptions of gravitational waves in the novel.
