The Dark Forest (Chinese: 黑暗森林) is a 2008 science fiction novel by the Chinese writer Liu Cixin. It is the sequel to the Hugo Award-winning novel The Three-Body Problem in the trilogy titled Remembrance of Earth's Past, but Chinese readers generally refer to the series by the title of the first novel. The English version, translated by Joel Martinsen, was published in 2015. The novel's title comes from the dark forest hypothesis, coined by Liu in the novel, but described by astronomer and author David Brin as early as 1983, by Stanisław Lem in "The New Cosmogony" (from his book A Perfect Vacuum, 1971) as a possible solution to the Fermi paradox and by Greg Bear in 1987 in his novel The Forge of God.
