Revisions (Stargate SG-1)

"Revisions" is the 5th episode from the seventh season of the science fiction television series Stargate SG-1 and is the 137th episode overall. It was first broadcast on the Sci-Fi Channel on July 11, 2003. The episode was written by Joseph Mallozzi and Paul Mullie and was directed by Martin Wood.

In the episode, Stargate Command discovers a civilization living in a seemingly perfect dome on an otherwise toxic, unliveable planet. After making contact, SG-1 learn that the inhabitants are all neurologically connected to a central computer known as The Link, from which they can access any information, at any time. Believing everything is not as it seems, Major Samantha Carter (Amanda Tapping) learns from one of the inhabitants, Pallan (Christopher Heyerdahl), about their technology, whilst Dr. Daniel Jackson (Michael Shanks) attempts to find out more about planets history and the dome's creation.

The writers pitched the episode as a standalone story, that would not rely on any of the greater mythology of the show, whilst hoping to recapture the team-driven exploration stories found in earlier seasons of Stargate SG-1.
