As for bad science in Star Wars, a long time ago in a galaxy far away they were using the parsec as a unit of time? So very wrong on more than one level.
Ahh the Falcon's famous Kessel run
Anyhoo it may not be that bad, after all it is a galaxy far, far away and perhaps they just happen to have the same word but to them it is a measure of time not distance. Of course it was probably just a sciencey sounding word and as a unit of time ill thought out. Of course the masters of just slapping labels to ill thought out time and distance concepts was good old Battle Star Galactica the original and bouffant.
Hope is but the first step upon the road to disappointment.
