Once there was, and still might be, a highly advanced alien race somewhere in the galaxy. They built a vast network of stargates...machines that allowed an almost instantaneous travel from one planet to another no matter how great the distance. Each stargate was connected to two others like the links of a great chain.  Each stargate had four basic functions.  Entrance, exit, relay and adaptor.  Entrance and exit are self-explanatory. Relay is the connection(s) between the entry stargate and the exit one. Adaptor makes it possible for the traveler to safely exist on the planet the exit stargate was in orbit over.
