"Smoother and rounder than a bowling ball" is my usual comparison

[-] Eheran@lemmy.world 1 points 11 months ago

I think that would be too much. A bowling ball is really smooth. It would not roll as well with such deviations all over the place.

At a diameter of 22 cm, the roughness would have to be in the order of 0.3 mm, which would not just be visible due to the distorted reflections, it would even be audible while rolling.
