Excellent writing, Ella, I like how you make the frontier area palpable, as our four-dimensional skin.
I am wondering if you are interested in reading my article in which I pose the question (and answer it) that choice is a fundamental aspect. I declare number zero to be fundamental and bring mathematical evidence to support the claim. It means that the idea of singularities must then be ruled out as a brain fart (I don’t use that word in the article) and not a mathematical concept.
