buoyancy only applies in gravity. The buoyant force on an object is equal to and opposite of the weight of the displaced fluid. No gravity, no weight.

- pulvinar 7mo agoThe goal here is neutral buoyancy when in gravity so that it behaves as though there were no gravity. Put a bag of water in water and it floats like the rest of the water, gravity or no.
- malfist 7mo agoNeutral buoyancy is achieved with very specific densities. You can either make the astronaut buoyant, or you can make the poop, but not both at the same time.
- __MatrixMan__ 7mo agoDo you need both? I assumed the astronaut has a handle or strap or something to fix their reference frame to the toilet. They can be only partially submerged.
- throwaway173738 7mo agoSo you’re strapping yourself into a material with the same density as poop and then pooping into it? How is that cleaner than pooping in a bag or over a vacuum?
