Doing the math on some of the stuff they've said on Voyager implies that they can do about 1,000 light years in a year, which is 1,000 times the speed of light.<br/><br/>I may have misunderstood your math (please correct me if I did), but to calculate like that, all the stars would have to be lined up at roughly equivalent distance.  Given their spacious three-dimensional nature, you can fit in a lot more than if they were arranged like road signs.  For example, you can cross a chessboard of 64 squares while only entering eight of them.  If my math is right, you could fit 1,000 stars into a 10 by 10 by 10 area, and only have to cross the length of 10 of their distance points.  I'm not sure how closely that equates, though.<br/><br/>We're also not 100% that each point is a star.  It's probably meant to be, but things go on by way faster than the eye can see.
