Question: Does the 3D aspect of the 'Edge' act like a (hemi)sphere, or more like a cube? In other words, if a flying fandom would approach the Edge, would they be forced closer towards the ground ((hemi)sphere), or simply slow down more and more until they effectively hit a wall?
Initially I had been thinking of it like a sphere, but, you bring up a good point about the flying thing. o.o A cube seems like a weird way to think about it, but, now that you mention it, it might actually be closer to what I was going for.
Let's put it this way: If you're flying towards the Edge (of the land) but keeping your altitude consistent, then you wouldn't be forced down at all, because you aren't flying high enough to start feeling the sky's Edge. So, in that way, I guess it would behave like a cube. But the problem of thinking of it like a cube is the fact that a cube has corners. But if you were to approach the "corners" of the Edge, then you'd be feeling the Edge pushing from both in front of you
and above you, the total force of which would push you diagonally down, thus making it seem like the Edge acts more like a circle -- especially since the combined force of the Edge both in front of you and above you would feel more powerful than just approaching either one, so, that would make you think that, effectively, it
is more like a curve...
I guess the real problem here is that we're visualizing the Edge in terms of solid lines when it's really more of a gradient. You never really hit a "wall" so much as you just eventually reach the point where the force becomes too strong for you to continue -- at which point, it probably wouldn't feel very comfortable to continue standing there, and it would be fairly easy to lose your balance and be sent tumbling backwards.
So yeah, thinking in terms of gradients makes the most sense. Personally, though, my 3D spatial reasoning is just awful, so, I can hardly visualize the overall shape of it myself, much less put it into words. Maybe I could manage to throw together a graph or two if it would be helpful... (no promises about tonight, though). (Edit: OK SO APPARENTLY I AM
REALLY OUT-OF-PRACTICE WITH BOTH PHOTOSHOP AND ILLUSTRATOR, AND I FIND THAT CONCERNING.)
Second question: Does the 3D aspect also limit downward travel in the same way as it does upward travel? I'd assume so, but I figured I should just ask.
Yes, but you'd have to dig so far below the "Earth"'s surface to reach it that I can't really imagine anyone running into it. In fact, it's probably something that the residents of the Fandomverse also just sort of
assume exists, even though it's possible that no one has ever dug far enough to say for sure.
But seriously, thanks for the feedback. I'll try to make note of everything that people are confused about so that I can edit in clarifications later.
