1. Is Tarkin actually Vader's superior? It seems to be the case from the initial Death Star scenes.
2. What type of propulsion system powers the Death Star? It seems to get around pretty quick but there doesn't seem to be anything powering it.
3. There's no telling just how long it takes the Empire too find the hidden Rebel Base on Dantooine, but it sure seems to me it takes them a very short time indeed. After all the base is deserted. Wouldn't a deserted base would be a lot harder to find than one that's inhabited.
4. What's the purpose of the Trash Compactor? Surely it's more economic to just dump your trash out into the endless vacuum of space, instead of wasting precious energy on crushing trash.
5. Does Biggs actually tell Porkins to eject just before he bites the big one? What good's that gonna do him?
6. What exactly is a parsec, and why use that terminology in SW, after all they do also use minutes, days and seconds.
7. Obi Wan offers Han two thousand up front, and fifteen when they reach Alderan. What exactly is the currency on Tatooine, or the Star Wars Universe in general?
8. If 3PO was created by Anakin, why does it look like he's mass produced with several other similar bots sprinkled throughout the Universe? Was he a kitset? or did Anakin build the prototype that was subsequently cloned en masse? (I have to admit, I haven't watched much of the prequels so that one's probably slipped by me.)
Ok that's about it, hope I don't sound too stupid asking these questions, or am overlooking something blatantly obvious.
