Stargate SG-1

Secrets - S2-E9

Factual error: When O'Neill throws the knife at the system lord at the end, the knife is spinning in the wrong direction.

Show generally

Factual error: Before SG-1 switched to P90 PDW's, they carried MP5 submachine guns. They were often shown with a full magazine taped upside down to the one in the weapon, so that to reload, all they have to do is remove the magazine, turn it over and insert the full one. Team members were also shown doing just that in several fight scenes. Problem is, real special ops troops are specifically taught in training never to do this. It's far too easy to damage the lips on the spare magazine, rendering it useless. There are clips that will hold magazines upright side by side, but its easy to see on screen they weren't using them.

Season 1 generally

Factual error: Earth's Stargate is dialed up more then once in series 1. Mostly in the first episodes, the passive gate is also shown with a rotating dialer ring when being called. This is not correct. The called gate only illuminates the chevrons. (This is classed as a 'factual' mistake within the show, not a 'continuity' error, and the option to change type has been removed.)

Children of the Gods (1) - S1-E1

Factual error: The escort for Colonel O'Neill is wearing both Major and Staff Sergeant rank insignia. Probably what the writers thought was a "Sergeant Major", which does not exist in the Air Force. Major is a commissioned officer, sergeants are non-commissioned officers.

1969 - S2-E21

Factual error: During SG-1's trip across the nation they show a city-scape of Chicago. Which is evident by the Sears Tower. But the Sears Tower was not build in 1969. Construction started in 1970 and completed in 1973.

Children of the Gods (1) - S1-E1

Factual error: Carter claims that the gates shift position because of the expansion of the universe. Gravity sources within a galaxy completely compensate for such expansion. The gates would still experience "stellar drift", which is mentioned earlier in the same episode. Stellar drift occurs because stars orbit the galactic center independently.

A Matter of Time - S2-E16

Factual error: The star collapsing into a black hole suddenly seems to increase its gravitational pull on the planet that SG-10 is on. When an object collapses to a singularity, the pull it exerts on an object does not suddenly change because the mass, and therefore the strength of its gravity, has not changed.

New this month Suggested correction: Black holes certainly increase gravitational pull and can tear planets apart. In additions, black holes are pulling in matter around it, adding to its mass.

A star and a black hole formed from it have the same mass and cause the same gravitational pull on objects outside the star's original diameter. Yes, a black hole pulls in matter around it, but that is the exact same matter that would also be pulled into a star of the same mass, so again the star and black hole would have the exact same effect on everything around it, including the planet. Regarding black holes (and stars) pulling planets apart, that is from tidal forces that grow exponentially as they approach a large mass, and again for objects at a distance outside the stars original diameter a star and black hole of the same mass cause exactly the same effect. The reality is when a star collapses into a black hole, some of the matter gets ejected and causes a supernova during the process, so the planet would have been torn apart long before any black hole was present, with the planet's debris thrown away from the event, not sucked towards it.

48 Hours - S5-E14

Factual error: In the scene where O'Neill and Maybourne are looking up NID flight plans, the plan viewed on the computer lists the destination airport as Minot Airport Base, but provides the airport code for McCarran International Airport (KLAS). It also lists non-existent runways, as in runway headings that do not exist anywhere in the world. (00:24:15)
