10 Massive Stargate Plot Holes
1. Trial And Error Would Have Fixed It
This one goes all the way back to the Stargate movie from 1994, however it is a rather big head scratcher! Daniel Jackson is brought on board the Stargate program due to his experience in Egyptian hieroglyphs, coupled with the fact that he is a genius. However, was his genius really required, or would common sense have fixed the issue that had so stumped the scientists?
There are 39 different glyphs on the Stargate's inner ring. A Stargate address requires a combination of six glyphs, with a seventh glyph acting as the point of origin. The team of scientists who are working on the program have had access to the cartouche, on which the order of the first six glyphs were clearly stated.
Even without the seventh glyph written down for them, simple trial and error would have resulted in the team eventually discovering the final symbol. It is not outright stated in the film (later retconned in the series) that they know exactly what the Stargate is, though they are said to have a strong inclination. There is a clear moment of profundity when Jackson identifies the seventh symbol - suggesting it was simply this final symbol that they were looking for.
The moment is a fun reveal early on in the film, leading to the first, beautiful Stargate activation - just don't think too hard on the thinking behind it!
