@akater@coolboymew also toroids are super unstable and likely to catastrophically collapse into a sphere at basically any time, iirc if you put a bunch of huge moons in weird insane orbits like figure 8s and one that goes up and down it becomes more stable because of the tidal forces. if toroid planets exist irl they won't for very long
@akater@coolboymew i mostly just checked if the thing could physically exist without immediately collapsing into a sphere, and then checked other things that i was curious about afterwards. the answer was yes but only if it's spinning really fast to counteract gravity. created some really friggin weird effects on gravity on the surface at sea level, the equator's gravity was about half of the gravity on the top or bottom. it was all done in service of trying to create a 16-bit jrpg-style world for a tabletop campaign, so i don't really have any records, just loose campaign notes.
campaign didn't go anywhere because i realized i fucking hate DMing 5e so the math's somewhere in a GM binder that's god knows where
i used one of those research paper piracy sites to swipe a bunch of physics papers about the formation of planets and moons and cobbled together the math from that. would have been way more sane and easy to say "a wizard did it" but it wouldn't have given me cool notes like the totally fucked equatorial plate tectonics spewing ash and acid and lava everywhere.
also secret of mana's cannon transport totally works if you're on the inner equator
@coolboymew i spent a lot of time doing math to check if this kinda world topology was possible
it is, and you can have a moon going straight up and down in the middle of the donut and another moon doing a figure eight. it's kinda awesome and i wish more games would do this deliberately
