Ah, this is suddenly reminding me of something else I hate about the EU -- something I acutely hate.
According to Wookieepedia, the peoples of the galaxy don't understand the physics behind hyperspace; they don't know if it's some form of higher dimensional space, a completely separate parallel universe, or the regular universe simply viewed from a FTL perspective, but they still know how to build functioning hyperdrives.
If they don't understand any of the physics behind hyperspace, how the hell can they constuct an engine that allows them to travel through it? It's like saying the creator(s) of the electrical generator learned how to build the technology without any knowledge of electricity, electromagnetism, etc.
It's stupid -- utterly, completely stupid.
