 Surprisingly, given the widely publicized 1975 publication by Stephen Hawking of the theory of quantum evaporation, few of the works incorporate this idea (notably "Earth" by David Brin (1990) and "Olympos" by Dan Simmons (2005)).Many early stories about black holes incorporate the concept that a black hole may contain a wormhole (known earlier as an "Einstein-Rosen bridge") that could be used for transportation; a concept that was at one time considered plausible, but is not currently accepted.More on wormholes can be found in the wormholes in fiction article.
