The DS9 tech manual says that the original design was to have the pylons arc out instead of in, to make their docking areas more accessible, but it was decided to arc them in to make it easier to contain the whole structure (as well as an docked ships) inside to perimeter of the station's defensive shielding. So, compactness was an issue at some point.
It's more like there was a desire to provide the internal empty space with docking ports - apparently, there was always going to be enough space there to accommodate entire starships.
These people spend most of their time in the core and various rings
True - but that only makes the experience of being high up in one of these tall towers a more intense one. The heroes often enjoy this for effect, such as in the aforementioned "Crossover". So it's quite like a "Die Hard" remake, with the hero finally emerging from the top of the elevator shaft of Chrysler Building and thinking "I have to get
up to the Empire State Building now to defuse that other bomb!". There would be a time for the "up" thought, but before that, there would be a concern about getting "back" down to what amounts to street level.
Right. And I figure the reason for that -- as it is on ALL starships -- is that artificial gravity is hard to control and a uniform direction on all decks is preferable, even if that direction is really inconvenient for the shape of the deck space.
...Which would explain why the Cardassians would want to do a disk
plus prominent towers if they wanted two separate functional sections for their station, each with its own direction of gravity.
The Cardassian transport from "For the Uniform" -- the one Eddington shoots down while he is trying to escape after poisoning the colony -- is implied to have physically taken off from the surface of the planet.
It's said to be spiraling down after losing power. But takeoff is not implied in any sort of preference over the more usual (and, in a disaster, much faster) beaming up of passengers/cargo.
I turn to you and say "Let's head down to City Hall and hand in this report." What direction are we about to go? Up or down?
Since parking lots tend to be frightening mazes, I'll take your word for it and head down in order to get out and get my bearings...
OTOH, while going "down" is a well-known, existing expression (for a variety of things, most of which don't apply here), there is AFAIK no equivalent expression for going "up" to places unless they are physically above the speaker. That is, downtowns may indeed traditionally be downhill, but even "going up to the Capitol" requires local knowledge of the local Capitol indeed being up on a hill and isn't universal.
FWIW... Is there a resource for Level numbers aboard the station? I can't remember any instances other than these two episodes, and the data there doesn't seem to create any helpful limitations or criteria, other than the low numbers starting from the very top of an upper pylon.
