How does laser cooling work?

Let me get my calculator... okay, slow protons in a single direction with a laser. Okay, so there are only 360 direction. Wait that's degrees on a circle. How many circles in a sphere? How many dots in a line? How many angles are there? Oh, I member... there are infinitely many circles and infinitely many angles, so infinity time infinity? Or infinity to the infinite? Well, I think I need infinite lazers to start with. I'll get on Amazon and order just enough for a circle, so green or red or blue infinite lasers? Oh, protons are only allowed to go in 6 directions. Oh yeah. Stop Proton, you are only allowed to go in 6 directions. 4:40 did you just plug NASA? LOL! I had a cool hunch. That seems to be a thing now in 2019.
