Taking a new stab at the Hadwiger-Nelson Problem

(There's a comment with fixes for the P formula at 7:41 to 8:02 and the PB formulas at 19:33 to 20:33) Beginning of this year I had a little intrusive geometric thought about the Hadwiger-Nelson problem that has sent me into a chase for a solution yet again. I'm cleaning up a lot of my old intuition and try my best to make sense of this unsolved problem that has nearly endured for a century while trying to keep it accessible and engaging even for those without a background in graph theory. It's a journey through optimization and into a rather strange way of measuring sets.
