So I think I asked about this once before on the old site, but didn't get any satisfactory answers. I just checked the wiki, there's still next to nothing on the Aether page. So is there anyone that specifically knows a good deal on Aetheric Wind Theory and Aether in general? What is it, how is it formed, why do you think this theory is correct and so on.
Aether was first coined as a term in the 19th century and was believed to be a substance that permeated all space, including the area beyond the earth's atmoplane, and provided a medium through which waves of light, gravity, etc may travel.
More modern scientists tend to discount the idea of aether, but it remains in Flat Earth Theory and provides much of the same function as it originally did.
Aetheric Wind is the rising flow of aether swirling about the earth-disc due to Universal Acceleration. The aether moves faster than the earth, and in some models it is actually the aetheric wind that causes the earth to accelerate upward. UA is, of course, the force that gives rise to gravity, and as Aether propagates light, its motion upward also causes the curvature of light that causes us to perceive sunrise/sunset, as well as accounting for round-earth-esque phenomena such as certain observations of the sinking ship effect.
Also connected to Aetheric Wind is the idea of the Aetheric Whirlpool. The idea here is that as the Aether rushes up around the disc of earth, it comes back together above us swirling in a great vortex, not entirely dissimilar to water in a drain. It is this swirling motion that is though to give rise to the relative motions of the sun and moon, and also accounts for the fact that the sun moves faster in its orbit when it is closer to the edge of the disc, where it is inferred that the aetheric whirlpool spins faster, or at the very least has a more direct effect on the sun and moon. Eddies in this aetheric whirlpool also account for discrepancies in things like sight distance and local gravity.
As for what it's made of, it's made of aether. No one can say for sure how it is formed - Aether was the "dark matter" of the 19th century astronomer, you see, and still retains much of its mystery.
I have an aetheric wind model that I worked on quite a bit some time ago, and a brief outline of this idea can be found elsewhere in this forum. In my model, the aetheric wind carries light from object below the earth, and is also responsible for the southern sky and southern celestial pole.
I'm still developing the model because I think it works quite well as a disc model precisely because of how well it accounts for certain observations that others interpret as proof of a spherical earth, but speaking personally, my ideas about the shape of the earth have evolved, and I've come to subscribe to an infinite plane model in which celestial gears drive the movements of the heavens.
Still, I can't deny that the aetheric models work. One of the beautiful things about Flat Earth Theory, to me, is how diverse and varied it is. I don't believe the Infinite Plane model is any more or less valid than the Aetheric Wind model, and support both (and several other) schools of thought.
I believe Tausami also has done quite a bit of research on Aetheric wind and the Aetheric whirlpool, so perhaps he can chime in here as well.
