Earlier quoted context omitted.
Fun fact, the toroidal cat is actually a stable gravitational configuration along with a spheroid. There are upper and lower bounds on angular momentum and mass of course, but within those bounds you can have a toroidal cat orbiting its primary! Wait, what’s a cat again?
Complete tangent, but I’ve always wanted to ask someone else who thinks about toroidal gravitational physics: in the center of a toroidal cat (planet) of sufficient mass, does gravity “cancel out”, or are you instead being “pulled apart” in every direction at once, as if on a medieval rack?
Cancels out. To pull something apart, there would have to be a gravitational gradient, meaning the object would have to be pretty huge relative to the toroid.
