minus-square@[email protected]linkfedilinkEnglish14•4 months agoI learned that the oxygen around the earth is about as thick as a coat of paint on a pool ball, relatively. I’m not sure how accurate that is.
minus-square@Hagdoslink12•4 months agoSpace is about 100 km up, on a sphere that has a radius of 6000 km, so some 2% is air. A pool ball has a radius of 30 mm roughly, so 2% of that is 0.6mm. Seems like a very thin coat of paint to me, but roughly correct.

A coat of paint is like 0.045mm thick
