Stargate

A Stargate is a fictional device that creates a stable, instantaneous wormhole between two locations, allowing travel across vast distances in space or even between planets. Think of it as a sort of teleportation portal—by activating the gate and dialing a specific sequence, travelers can instantly arrive at a corresponding Stargate on another world. This technology, popularized by science fiction, enables interstellar exploration and communication without the need for spacecraft journeys that take years or decades. Its design often resembles a large ring with symbols around its perimeter, serving as an address system to connect different Stargates across the galaxy.
