Okie dokie, the other night while attempting to stave off increasing levels of being bored, I came across a YouTube video that compared the sizes of ships within scifi. Basically it was showing and increasing level of size, typical thing really.
After a wee while it displayed the Atlantis city ship, and then after it (meaning larger) came the Sokar built ship used by Apophis in Serpent's Venom and later destroyed after Replicator infestation.
This can't possibly be correct, can it? A Goa'uld built ship beating out the lost city of the Ancients?
