Corrected entry: Season 9, episode "Ripple Effect" I believe. Sgt Walter Harriman shouts "Unauthorized offworld activation" instead of "Unscheduled offworld activation". "Unauthorized" is only for outgoing wormholes, and makes no sense in this context. It is unlikely to be a character mistake as he generally says "unscheduled" two or three times per episode.Soylent Purple
Corrected entry: In an episode of "Stargate: Atlantis", the team uses an Asgard beam to get rid of a Goa'uld parasite from a human. There are several occasions in "SG-1" after this event where they could have performed this procedure. (One is the episode "10x19" when they try to get Ba'al out of Adria, but fail).
Corrected entry: In Season 9, Episode 9 ("Prototype"), there is a shot of the team exiting the stargate on the prototype's planet. The gate's event horizon (the watery-looking plane they walk through) has a flat base and the gate's rim (the stone circle) is shown disappearing into the ground, as if the base of the gate is slightly buried. It's been long established that the "wave" that bursts from the gate when it opens vaporizes any matter in its path. Therefore, the part of the ground that is covering the event horizon in this shot should have been vaporized the first time this gate opened, leaving a shallow trench stretching out in front of the gate.
Corrected entry: Whenever we see the stargate on a remote planet being dialed either from an incoming or outgoing wormhole, the inside ring (with the symbols on) never spins. I would imagine this is because it would cost too much money to bring all the equipment needed and use too much time to spin the inner ring on location, as the inner ring always spins when inside the SGC (the set of is obviously always set up). The sound of the ring spinning can even be heard.
Corrected entry: When a stargate first opens, we see what looks like a splash of water. In "Prisoners" we learn that this is an unstable wormhole being established between stargates, we also learn that anything in the way of the splash will be instantly disintegrated. How then is the Iris not disintegrated when the stargate opens while it is closed? Granted, the iris is slightly inside the event horizon, but if it would not be affected because of that, the splash should be seen coming past the iris. Neither of these things ever happens.Sol Parker
