de Sitter–Schwarzschild metric — In general relativity, the de Sitter–Schwarzschild solution describes a black hole in a causal patch of de Sitter space. Unlike a flat space black hole, there is a largest possible de Sitter black hole, which is the Nariai spacetime. The Nariai… … Wikipedia
De Sitter effect — In astrophysics, the term De Sitter effect (named after the Dutch physicist Willem de Sitter) has been applied to two unrelated phenomena. The De Sitter effect was first described by de Sitter in 1913 and used to support the special theory of… … Wikipedia
