Stargate is a fictional matter transmission device that can transport matter and energy across vast interstellar distances, as well as different points in time. The device is a central element in various media franchises, most notably the Stargate film series and television shows. The original concept was introduced in the 1994 film Stargate, directed by Roland Emmerich, and further explored in the television series Stargate SG-1, Stargate Atlantis, Stargate Universe, and other related media. The Stargate device is typically depicted as a ring-shaped structure with a central dialing mechanism that allows users to input coordinates to specific destinations. In Hebrew, "Stargate" is translated as שער הכוכבים (Sha'ar HaKochavim). The term "Stargate" has also been translated in other languages, such as Stargate in French, Stargate in Spanish, and Stargate in German. The Stargate concept is rooted in the idea of wormholes, a theoretical passage through space-time that could create shortcuts for long journeys across the universe. This concept is based on the Einstein-Rosen bridges, a solution to the field equations of the theory of general relativity. The Stargate device is often portrayed as a means of interstellar travel, enabling characters to explore distant galaxies and encounter various alien civilizations. The franchise has spawned a rich mythology, including ancient alien races, advanced technologies, and complex political intrigues.
