Re: What would a literal "under-world" look like?
Hmm, maybe the spin of the planet pins everything except the core itself to the inner "surface" of the planet. The core acts like a sun that is permanently stuck at noon, rotating in place as a hot dull lump of iron. Water vapor and clouds are turned into steam and blown back to the "surface" as hot vapor so it's very lush and tropical without a lot of standing water. Like a green house space colony.
