Re: The "Hirogen" communications network... good lord, was that thing
The brightly glowing parts of it, certainly. But Trek has shown that planets and civilizations exist around the unlikeliest of stars, so there could well be star systems of significance in the galactic halo as well. And that's roughly spherical, and thus tens of thousands of lightyears "high".
i think the more important question of note is why that snap shot you took has the closest antenna in the network perhaps some 25 thousand light years from the border tot he Alpha Quadrant.
...If we assume that the four spokes there denote quadrant borders, that is.
Funnily enough, this appears
not to be the case. The onscreen route map of the
Voyager, as reproduced on pp. 76-77 of the
Star Charts booklet, shows a galactic spiral that is shaped or at least oriented quite differently vs. the axes.
If we instead assume those spokes represent the centerlines of the galactic wedges, with the UFP in the middle of the wedge with the additional edge symbology, then the commnet layout makes perfect sense...
(No, that doesn't exactly match the canonical galactic spiral, either. But it's a somewhat closer match...)
What have we explored of the Alpha Quadrant, according to the sometimes-wrong, often-"right" Star Charts? Like... 15% of it or something?
"Where No One Has Gone Before" says 11% of the galaxy is explored (without specifying quadrants; these episodes preceded the invention of the four-quadrant system, after all); "The Dauphin" says 19%. Take your pick, invent your excuse, redefine your terms...
