So what your saying, Craig is that the 75,000 light years is the distance "as the crow flies", but Voyager had to go around such things as Nebulae, The Necrid Expanse etc (although I think they went thru that, but you get the idea).
How did they know what obstacles would have caused them to divert etc, before they reached them.
I always thought of any distance, and consequent estimated time to cover, in Star Trek as a straight line from point a to point b.
As I understand it, while at Warp, obstacles don't get in the way. (One example is Worfs' brothers escape from an attacking Klingon ship during the Klingon War, where he heads for the Sun and goes to Warp just as the ship is about to break up).
I may be wrong. My understanding of Warp theory is a bit lacking compared to some Trekkies.
Still you have to admit, it's great fun talking about it. ;D
