What a formalistic construct of the human mind has to do with reality is anyone’s guess. Higher mathematics is ingenious and a great exercise in following through some set of formal definitions of concepts (aka “axioms”) to their formalistic logical implications, but what else? Sure, sometimes these have practical applications when we can express the formalism through physical phenomena instead of abstractly through symbols, but even then, it’s not reality and it’s not some secret code of reality, but a decent approximation of some narrow aspect of it. What do mathematical infinities have to do with a real infinity? What does something like the real number line have to do with a real extended physical space? Not much, besides being attempts to represent phenomenal realities through conceptual schemes.
