Gentlemen, please learn your physics if you are going to use it to argue. Some of the "dark matter" arguments I've heard in here are absurd! Not that it matters in Star Wars. If it looks good, do it! But if you do use science, use it right, or the Phantom will get you! Mwahahahahah! Btw, dark matter = mathmatical construct used to explain the motion of stars in a galaxy. The stars move in such a way that there must be something there, but nobody knows just what it is yet. We have no idea what dark metter is, but it sure as heck ain't antimatter.
