Plot hole: Huge plot error: Apophis and Clorell (Skara) should not have survived the explosion in Season 2, Episode 1 (when they attack Earth with two ships). In "Family" they explain that Apophis and Clorell survived by escaping through the stargate aboard Clorell's ship moments after Daniel Jackson did the same. However, when Daniel Jackson escapes through it, Apophis and Clorell are not even on the right ship, and there is 1 second left on the C4 timer when Daniel escapes. They actually show Daniel Jackson escape, and then cut to Apophis and Clorell still aboard their ship. So apparently, Apophis was able to "ring" from his ship over to Clorell's ship, make it to the stargate room, dial an address, and escape through the stargate all within literally 1 second. Is this guy related to The Flash?
Suggested correction: That's not what happened or what was said. Daniel suggested Apophis and Klorel used the rings after he did, not that they used the Stargate after him. In "The Serpent's Lair", we see Apophis and Klorel use the rings BEFORE Daniel uses the Stargate. But we don't actually know how much time is meant to be left on the C-4 when they use the rings. They ended up using the Stargate before Daniel did and they never cut to them on board after Daniel escapes.
Revealing mistake: Even after Teal'c is dead, you can see in one shot that he is still breathing.
Plot hole: When the team manage to create the cavern with the buried stargate they send Teal'c through to drill his way out, but wouldn't it be safer (and significantly faster) to fire a missile or two through and blast their way out? They have no idea how deep the stargate is buried, or under what type of rock, so sending Teal'c with only four hours of air seems suicidal. (00:35:00)
Suggested correction: Except that sending a missile through would only cause the rocks to cave in onto the Stargate again and could possibly make it impossible to reopen the Stargate. If they could reopen it, they would just end up creating the same cavern. Not to mention the fact the danger to life on the planet if a missile did make it through and ends up exploding on the surface.
Except that if the gate is active, anything falling down on it would be destroyed, so if anything you would still end up with a cavern if material soil bound together as it was falling towards the gate, OR you would end up with a crater which would be Teal'c's objective.
It's not about the rocks being destroyed. It's about if the Stargate ends up shutting down and the rocks creating an iris, making it impossible to establish a wormhole.
Character mistake: At the end, Vala and Mitchell establish a wormhole and let Teal'c and Jackson know. Almost a minute passes before Teal'c and Jackson get back to the gate and Jackson yells "run" because they need to get through the gate right away. Obviously they're detained, but after being let go, Mitchell says they're sending the iris code now. This is something that should have been done sooner, especially after hearing gunfire, so they could be ready to go through when Teal'c and Jackson arrived.
Suggested correction: OR... after hearing the gunfire maybe it was smarter to wait until they verified that it was Teal'c and Jackson who prevailed. Otherwise, they risked leaving the gate open to a hostile force.
Perhaps they waited, but they still would have sent it when they saw them, which the didn't. And they've never waited like that before.
There But For the Grace of God - S1-E20
Continuity mistake: When the Goa'uld attack the alternate Earth they dial in so no-one can escape. However in future episodes the Russian Stargate program said that as long as a DHD was hooked up to their gate it would have priority. When the invasion happened they had a gate on the ship hooked to a DHD.
Suggested correction: The Goa'uld are well aware of this. All they would need to do is block the event horizon of their Stargate or disconnect the DHD and any incoming wormhole would default to the gate on Earth instead.
Other mistake: When the Asgard arrive to save the day they start by beaming out the Goa'ould but Teal'c gets left behind. He should have been beamed out with the rest of them.
Suggested correction: The Asgard know about Teal'c from the season 2 episode "Thor's Chariot". In that episode they upload his DNA profile into the Asgard computers so that he is not beamed away with the other Jaffa in that episode. His profile would have been kept so that he would known in any future contact situations with the Asgard.
This correction seems to have been made without watching the episode (or remembering the episode). The Asgard spoken of are from an alternate reality when they never met Teal'c (and don't have his DNA). One could suggest that alternate reality Carter told them about Teal'c, but there were two of them, and she wouldn't have known alternate reality Teal'c was later killed.
Trivia: Besides Don S. Davis and Christopher Judge starring with Richard Dean Anderson on MacGyver, in some episodes, the actor Steven Williams who played General Vidrine also starred with Richard Dean Anderson in S1-EP12 Countdown.
Suggested correction: I think this entry needs to be edited to simply state that many of the actors on "Stargate SG-1" also appeared on "MacGyver". Besides the three mentioned, there have been over a dozen other actors who were on both shows, including Robin Mosley and Garry Chalk.
Plot hole: The team go through the gate to disable a drone with the intention of being able to close the active Stargate, but once they go through in a submarine, the gate closes behind them, rendering the mission pointless. (00:24:18)
Suggested correction: This entry seems to have been made without watching the episode or you skipped a part. When the 3 enter the Stargate via the submarine, the Gate does NOT close behind them. It stays open, which we not only see but is how they can communicate with O'Neill. Then Dr. Markov says once they bring the drone in (to the submarine), they can shut the drone off and the Gate will close. Which is what they do (off-screen) and when they do, the Gate closes.
Citizen Joe - S8-E15
Factual error: At the end of the episode General O'Neill is introduced to Joe's wife. He is introduced as General O'Neill, but his insignia on his dress blue uniform is a Colonel - an eagle, not a General's star.
Suggested correction: There is no eagle insignia on his uniform. He has one star (on each shoulder) to signify General.
Stupidity: Some ancient advanced civilization took to the task of building this amazing net of stargates that enables instantaneous traveling over hundreds of light years or more, but any stargate can be disabled by anybody just by covering it with dirt or rocks. Apparently if the stargate is buried then it becomes inactive. See Season 1 EP.1.
Suggested correction: This is just you having a different opinion on how the Stargates should work. In fact, the ability to make a Stargate inactive by burying it is a brilliant move by the Ancients. Burying the gate, or even creating a barrier, prevents enemies (like the Goa'uld) from having a convenient way of invading a planet. Although some races, like The Nox, show the ability to activate a Stargate without having to form an unstable vortex.
