10 Massive Stargate Plot Holes

10. Magic Eyes, Magic Dialing Device

This is a plot hole that stuck for so long, that it was actually retroactively fixed in the show! In the opening scene of the pilot episode, Children of the Gods, Apophis arrives on Earth to take new potential hosts. They slaughter the airmen guarding the Gate, and then turn back around and enter - booting up the Gate without the use of a DHD.

For years, this particular plot hole stood out. The Goa'uld didn't possess the technology to open a Gate in such a fashion, whereas species like the Asgard, the Knox and, in one version of the future, Humans do. Therefore, by the laws that the show placed upon the Gate, Apophis should have been trapped in Cheyenne Mountain from the very first episode!

However, Children of the Gods was re-cut and re-edited before SG-1 finished airing. In this re-cut, there is an added moment of one of the Jaffa actually placing a makeshift dialing device on the Gate itself, thus creating the wormhole to get them all home.

While some plot holes on this list can be explained away this way or that way, this was the first example of actually going back to the episode and fixing a mistake!
