Please don't confuse math with "reality". Math as about axioms and proofs (well-formed finite strings), and is often a useful tool in mapping the territory, but it is just that, one of the tools.

If a question about reality turns out to be logically independent of a model M, then M is not a complete model of reality.

Quantum Mechanics is a classic counterexample, as far as we know, in a sense that there is no deeper underlying theory that would predict an outcome of a measurement when QM says it cannot be determined.

Surely QM can't be a classic counterexample of anything.

classic != classical. English is weird...

Valid, but I've a high confidence grandparent was just a joke anyway, and classic ~ classical enough for that...

Please do not invent new abbreviations without formally introducing them first.

(Yes, I can figure out what it means, but I shouldn't have to. One should be able to use simple recognition to understand an abbreviation, without having to make any inference.)
