Mistakes

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. See more...

Trivia

When Daniel tells the others that he believes there is an entire network of Stargates instead of just two, he and Carter figure out that they have to adjust for stellar drift in calculating the new gate positions. She mentions that they should be able to 'MacGyver' something together. This is of course a nod to Richard Dean Anderson, who played MacGyver. See more...

Throughout the series, Daniel Jackson has worn glasses yet has used the sarcophagus on numerous occasions. If the sarcophagus can heal any wound and even bring back the dead, surely it can correct a small fault in his eyes. [The sarcophagus heals damage to the body. Daniel's eyesite is a genetic imperfection. The sarcophagus won't work on any defect the user is born with.]

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. [Almost all off-world stargates use DHDs to dial out. DHDs allow stargates to "fast-dial": entering the symbols without spinning the inner track. The SGC doesn't have a DHD, so they have to dial "manually" each time by unlocking the inner track with an electrical current and spinning the symbols to the chevrons.]
Edit
Off world Stargates do not seem to dial usually. Most times you never even hear the inner ring turning. [Offworld Stargates are controlled by a Dial-Up Device, they probably don't need to dial themselves up manually like Earth, because earth has no Dialer.]

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. [It is thought of that a wormhole can still be established even if the "splash" is prevented due to the iris as in episode "A Hundred Days" where the stargate is buried, they are still able to dial to it because an iris of sorts was formed (they explain this), they used a proton accelerator (or something) to create a space. Once the space is large enough they can then dial and the "splash" will encompass the whole cavern making it even larger. So for the splash to occur there just needs to be a volume large enough to encompass a minimum amount of the splash.]
Edit
There is no way to fit a twenty foot wide circular hunk of metal that far down into the Cheyenne Mountain Complex. We never see anything larger than a personnel elevator so how did the Stargate get down there? [In the first episode of series 6 (Redemption), it is explained that there is a retractable roof (remember it used to be a missile complex).]

Throughout all episodes, when communicating via radio through the gate, they are always talking in real-time. However, there would be a delay on all transmissions equal to the time it takes for an object to travel through the gate. [But it's not an object, it's electromagnetic radiation. It can go both ways through an open gate, which solid objects can't; so why can't it move through the gate faster than solid objects?]

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). [The level of technological understanding in Stargate improves throughout the years so there would have been a time where the idea was deemed was an inappropriate risk. Also the ship assigned to Atlantis has an Asgard on board who would have more knowledge of his own species technology than another species would.]
Edit
The Stargate in the series is slightly different from the one in the movie. The top chevron moves up and down to lock the symbols, the other chevrons just light up. In the Stargate movie, the chevrons all move in and out to select the chevron. [The movie and series do not go hand in hand. Some changes were made, such as how Ra was actually an unusual looking alien who took over the boy's body.]
Edit
In the series 8 episode, :Lockdown," why didn't Anubis just kill the members of SG1 when he Zatted them? He would've been dying to kill them considering they wiped out his fleet and destroyed his physical shield. [Because then there wouldn't be a show.]
Edit
In season 1 episode 18 "Solitude" Carter and O'Neil get trapped on a planet where the DHD does not work, they say that eventually they may get rescued by another team, however if the other team gets there then how are they themselves supposed to get back since they cannot dial home and neither can SGC dial up to them since it is said countless times that you cannot go through a wormhole unless you dialed it, i.e. it is a one way thing. [But when dialing a world, they always send a probe through first to make sure it is safe and if there is a DHD, so when they send the probe, they could radio the SGC and tell them the DHD is broken which could then be fixed or replaced.]

In the Season 8 Episode 'Threads', Jacob Carter repeatedly mentions blending with Selmak 4 years ago, placing it in Series 4 (each season constitutes a year). However the blending occurred in Series 2 (6 years ago). [Each season will be a year on our calendar, but not in Stargate, it doesn't run in real time.]

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. [The "Wave" only protrudes from the center of the gate and not the entire gate, hence no trench on the ground.]
Edit
In series 9 episode 6, Beachhead the Ori plans on collapsing a planet to form a black-hole, unfortunately you need a really big sun (several times more massive than our sun) before it will do this, there's no way a planet will naturally form a black-hole. [Any object of sufficient mass will form a black hole. As you point out it would need to be several times the mass of our sun. Perhaps he planned to put a stargate on the planet and send a super-dense material through.]

Whenever you see the bottom of a Ha'tak vessel (Goa'uld mothership) the pyramid is triangular at the base, but somehow they can still land perfectly on a square pyramid landing-pad. [The material that the Goa'uld make their ships, and most other things, from can morph and change shape. Look at Ra's guards and ship in the movie or Heur-ur's guards in the series to see this happening.]
Edit
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. [Why could this not be a character mistake? People sometimes say the wrong thing inadvertently, so this actually makes Walter appear for "real" in a sense, so this would not be a production mistake.]

In Episode 117 - Solitudes, the DHD of the second Stargate can be seen. It has a point of origin different to that from the gate found in Gizeh. However, after SGC starts using the Antarctican gate at the end of season 3 the glyph indicating the point of origin on the gate and in the computer systems is still as seen on the gate from Gizeh. [Point of origin is not an aspect of the gate or the DHD. The pyramid with the circle on top is the symbol for Earth. The gates found in both Giza and Antarctica use the same symbol. Carter originally thought the one in Antarctica used a different one because she thought they were not on Earth.]
Edit
Throughout the series, incoming wormholes are indicated by the chevrons lighting up one by one - but the incoming gate could not "know" a connection was coming until the connection had already been made and the wormhole formed. [You have to dial up the destination stargate. It has to be aware that a wormhole is about to open, or the connection could never be established. Just like your telephone rings before you pick it up and begin speaking, the chevrons light up to open the wormhole.]

Season 8 Episode 12 "Prometheus Unbound" - When Daniel threatens Vala with the Zat, she says that she is still wearing the Kull suit and is therefore immune to it. Some time later, Daniel shoots her with the Zat but despite him hitting the suit, she goes down. [Vala was incorrectly assuming that the Kull suit would protect from a Zat with the helmet off.]
Edit Corrected by Grumpy Scot
The DeLuise brothers appear from time to time throughout the series. For example, in Series 5, Episode 15, Peter DeLuise plays the director of the sci-fi movie "Wormhole X-treme." He also appears in several episodes as a background character. [Seeing as they were also producers on the show doesn't make this trivia.]

Enigma (series 1)

When Jack first tells Daniel to dial home, he brushes off the edge of the DHD which is covered with about 2 inches of ash, but when we see the DHD in the background just seconds later, it has only a light dusting of ash on it. [The DHD only has a light dusting of ash because Daniel had to brush the ash off to dial home which is why there is less ash on it.]
