Roundest ball ever made

What did science ever do?
Can science smoke a brisket? Doubt it

Cooks, The Science of Good Cooking, brisket page 70-74:

 
The primary mirror on the Hubble space telescope was polished to a level where that same comparison of expanding it to earth size would result in a difference between the high and low spots being only six inches. The Hubble mirror is 7.9 feet in diameter, which is orders of magnitude more in surface area than the sphere, but I'm guessing the shapes pose their own set of complications. And we all know what happened when the Hubble was first deployed.

This stuff is very interesting to me, so thanks for posting!
Considering that the Hubble can see the Cosmic Background Radiation, the age of the universe of 13.7 billion years, with an 8ft shiny dome is pretty amazing.

This is pool related because pool exists within the observable universe.
 
Lotta jokes here. But seriously, what if? The difference in the cloth I grew up playing on and the Simonis I play on today literally changes how the game is played. Template racks change how the game is played. Jump cues change how the game is played.

What if balls were manufactured cheaply and easily with drastically improved roundness? What impact would it have on the game? Does this roundness equate to smoothness? Would it reduce friction? Would cut-induced-throw and spin-induced-throw be reduced? Would gearing english be less important? Would the miscue limit move inward? Would chalk be less effective? Would we seek different materials for tips?
