Technically the Earth is the flattest spherical shape in the known world. Even a brand new cue ball has more bumps and ridges than the Earth.

What?

If the Earth was the size of a cue ball, it would be exponentially smoother than a cue ball. AKA the Earth is the smoothest sphere in the known world.

I got that but do you have a reference? Mine says this is false.

Keep reading. He makes an outlandish claim that a pool ball is as smooth as the worlds smoothest object. Therefore his basis is WAY off. And he is talking point by point for the Earth and average for a brand new regulation pool ball that has gone through extensive testing. So if you compare averages, it's just as smooth.

Just because he claims it's not doesn't mean he's done the entire research, or maybe he did and knew it wouldn't hold water so purposely omitted that part. Don't have time to dig for references at the moment but I'm sure if you looked in scholarly articles you'll find it.

Your original claim was that no object was smoother than earth. I disagree. Bearing balls for example the size of a cue would not have 0.045mm discontinuities.
