fictional universe

It is difficult to determine what actually constitutes a "fictional universe." Sir Thomas More's Utopia is one of the earliest examples of a cohesive imaginary world with its own rules and functional concepts, but it comprises only one small island. Some, like Robert E. Howard's Conan the Cimmerian stories, are global in scope, and some, like Star Trek and Star Wars are galactic or even intergalactic. A fictional universe may even concern itself with more than one interconnected universe through theoretically viable devices such as "parallel worlds" or universes, and a series of interconnected universes is called a multiverse. Such multiverses have been featured prominently in science fiction since at least the mid-20th century, notably in the classic Star Trek episode, "Mirror, Mirror", which introduced the mirror universe in which the crew of the Starship Enterprise were brutal, rather than civilized, and in the mid-1980s comic book series, Crisis on Infinite Earths, in which countless parallel universes were destroyed. The Hitchhiker's Guide to the Galaxy, when considered as all 5 books together, flits back and forth between different universes, or perhaps it is more accurate to say, flits through different timelines and different dimensions involving different states of existence for the characters and for the earth itself.

Les mondes imaginaires sont un thème récurrent dans l'imaginaire des hommes et ce pour une multitude de raisons : tâcher de comprendre le monde qui l'entoure, critiquer ce monde, s'en évader, le fuir, ou pour le simple plaisir de créer, de modifier, etc.

Die Erfindung fiktiver Orte oder fiktiver Welten ist ein beliebtes Element nicht nur der Science Fiction, Fantasy und Utopie-Literatur, sondern auch der politischen Philosophie. In Rollenspielen, insbesondere in Fantasy-Rollenspielen bilden die fiktiven Welten einen zentralen Punkt.Die Tätigkeit des Erfindens solcher fiktiver Orte und Welten wird auch als Weltenbasteln bezeichnet.

Вымышленная вселенная, авторская вселенная, авторский мир — термин, применяемый критиками и поклонниками по отношению к вселенным фантастических произведений, действие которых происходит в мирах, отличных от Земли по физическим и/или географическим реалиям. В более широком смысле термин употребляется по отношению к условиям любого фантастического произведения, даже если его действие, согласно сюжету, происходит на Земле (см. например, Вселенная Дозоров). Аналогичен термину «сеттинг» в ролевых играх.
