Other: Osiris is a male Goa'uld in a female host (Dr. Sarah Gardner). So why does this MALE dress his host in tight, midriff-bearing, butt-accentuating outfits? It isn't to manipulate other Goa'uld, because sexual reproduction between hosts is forbidden as the child would be Harsesis and most Goa'uld find the thought of sex repugnant. While Goa'uld are physically genderless, they do, without exception, refer to themselves as male and female. Egeria and Hathor, both queens, are referred to as female. Apophis refers to Klorel/Skaara as his "son", not his offspring. If they had no gender, they would never call other Goa'uld "mates" or "children". Further, other females never dress this way unless trying to sway someone to their cause (such as Nirrti trying to seduce Jonas Quinn) and Osiris dressed like this well before she ran into Daniel again. There is no logical or plot motivated reason to dress Anna-Louise Plowman in these costumes other than eye candy for the audience!

Revealing: Even after Teal'c is dead, you can see in one shot that he is still breathing.

Factual error: When listing off the items Orlin has ordered online to produce his own stargate, Simmons lists "seven 100,000 watt industrial strength capacitors". Capacitors are measured in farads, not watts. Not to mention that as of now, the world's best capacitors are less than 10,000 farads, not an order of magnitude higher.

Plot hole: Carter says that the chance of depositing the heavy element inside the Katow sun while the element is en route is about 1%. However, hypothetically speaking, the actual chances would be infinitely smaller, in fact it would be near impossible. Simply consider the distance from earth stargate to the Katow stargate, the diameter of an average sun, and the time it takes for an object to travel through the gate (about 12 seconds). Taking the closest star to us (Alpha Centruri), at a distance of 4 light years, this means that the wormhole takes ~443ns (0.000000443s) to pass through the sun (using our sun diameter). Similarly, taking the diameter of the Milky Way as the distance to the furthest star in our galaxy, ~100000 light years, meaning the wormhole takes ~17ps (0.000000000017s) to pass through the sun. This means that the SGC would have to shut down the gate within a a maxmium of 443ns or a minimum of 17ps time gap. As we have previously seen, the stargate takes far longer to shutdown than these miniscule time lengths.
