Watchtower Gothic.



So one of the features I've been waiting, waiting, waiting on in my game is definately coming in the next iteration: the Watchtowers, aka space elevators. On account of this, I've sort of been translating the real world physics of a space elevator into the imaginary world theosophics of a Watchtower. Which, well. Contemplating celestial mechanics & astrophysics makes my head go all melty. For instance, I was (trying) to do the math on where you would be able to see the Watchtower from; the horizon formulae, yeah? Well, assuming that the Watchtower was 5000 kilometers tall, well it should be visible...from everywhere except for the places where it was occluded by the disc of the Urth? Crap, now I have to figure that out? I if I have seven of them....well, suddenly which Watchtowers you can't see becomes a more interesting factor, doesn't it? & if all of them are spaced out around the equator...okay, here is another thing I am working on. I finally wrapped my brain around how a "sundial" effect works at the equator; rather than spinning like a clock, it just starts long, gets short, at noon has no shadow, then gets longer in the opposite direction. Great-- but what happens when it is of such a riculous height? & speaking of, shouldn't the other six also cast a band of shadow; so like, the equator is shrouded in shadow? Or no; it follows the sun? I...wait, I can't...I need to start making calculations where the diameter of the Urth is the limiting factor? This is really punishing my brain, & I haven't even tried to figure out penumbra & antumbra. I need someone who is good at thinking about this stuff to help me, like the world's greatest high school science teacher, or somebody. My noodle aches. Oh, & how shadows are cast in a depression, a bowl-shaped crater. I need to work on this stuff. What do they look like at night? ribbons of light, right? Like, at what point do they begin to reflect the light of the sun themselves? Once they get out of the shadow of the Urth, right? Okay, that is awesome.
