I 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.

Space 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

I was once told that if you scaled the earth and a glass marble to be the same size, the earth would have a much smoother surface.
