i think this is more philosophy, but leibniz did talk about this phenomenon, that no matter the laws of the universe, no matter our perceptions, no matter what exists, math remains correct. you could have a universe with no time and no space and no matter in it that works completely differently, and integral calculus would still exist, because it is not bound to worldly things. which is why we study 4d geometry and unapplicable pure math, because they have no reason to not exist.
