Specifically the Athenosphere(upper Mantle) is what causes the tectonic plates to shift and expand and contract; as it is, the hollow models created by thorf just don't have a thick enough shell to support the athenosphere, and even if it did, the density of the material would have to be drastically increased to make up for the hollow center. the physics and geology of the whole situation is the main reason I'm hesitant to have the hollow world in my version of Mystara. I've been thinking about just transplanting the general cultures of the hollow world to a corresponding place in davania or skothar(nithia to Arypt). I have been searching for any scientific/pseudo-science explanation that would support the hollow world AND maintain the presence of tectonic plates, and none I have seen are remotely plausible. The closest I have come is this jewish guy who rejects western/christian science and in the process throws out gravity and explains the effects of gravity with electro-magnetism and some other weird stuff. I don't think his work is really correct or logical, but he's the only person I've seen who works through the equations and everything in a rigourously scientific manner.Big Mac wrote: ↑Thu Apr 04, 2019 1:16 pm
Has anyone looked at the real-world geological processes that were happening back in the Jurrasic Earth and looked at how that sort of process might still work on a planet that is actually a hollow world?
Could the Known World still have continental drift and all that other stuff going on without land needing to go in and out of the Polar Openings?
Or could the idea of things being "moved into the Hollow World" happen literally sometimes?
If you don't have that going on, how else can the Skothar mountain ranges be explained?
So the bottom line, either the world is solid and has tectonic plates, ergo continental drift, or the world is hollow and has a static surface (therefore not being earth in the age of magic). Of course you could always say 'because magic!' and have both
As the planet Mystara is a biological creature according to canon, I assumed there is NO tectonic activity. Yet Cellular activity instead.

These cells have their own individual movements (up, down, tilt, rotate clockwise, counter clockwise, or tilted, and more. New cells are added while old cells implode, dry out, and in between large caves areas become known(all not existing in such mass and size on RL Earth), on the surface (HW and OW) thus creating the land, mountains and sees, yet also enabling the many many ...many..plateaux existing on Mystara suddenly or slowly coming to be or sinking.
It also explains why Meteors have a different effect than on our RL tectonic world would be in case of an impact.
Just to help thinking in another way.
A living creature is namely NOT a tectonic world, and everything will be different, even if the outward appearance would suggest similarities. This includes; activity, changes, time of changes, resistances, gravity, and most and foreall something we on RL Eatrh absolutely don't have MAGIC.
