"Fanwank" is a term to explain creative (and sometimes dubious) justifications or explanations fans come up with for inconsistencies in SF/F settings in the name of the beloved willing suspension of disbelief. It's not necessary to do, but it's sometimes fun.
"Antifanwank" is a term that has very few hits on Google, but has the intuitive opposite meaning - people falling over themselves to offer (sometimes dubious) arguments as to how something just can't work in a setting.
I bring this up because I liked Firefly (and Serenity more then I expected), and over on RPG.net, the matter of just how awful a single-system 'Verse with no FTL is has come up once again. While there're've been some intelligent critics of this impulse, there's still far too many flat denunciations of the concept by people with no standing to make such astronomical proclamations. Ah, well.
Personally, I find it more fun to play at making sense of something I enjoy than to fret about its impossibility. The Serenity flies at 1.0 * Speedplot, and how they eat and breathe (and other science facts) only really matters when it does. If you don't like it, lump it. :)
Now, on the plus side, I did come across this lovely-looking "Official" map of the Verse. It's much like I reasoned after I thought about the opening Serenity monologue - it's a multi-star system. Throw in terraforming, modest constant-acceleration drives, and Bob is, indeed, your uncle who will let you run around in the Firefly setting... (OK, I just did a horrible thing to that poor metaphor.)
Anyone happen to have that map and have an opinion on how nice a poster it is? I might just pick that up...
