In particle physics this idea is referred to as “gauge symmetry” and basically it’s a mathematical principle so it’s verbose to break into words/concepts but essentially certain parts of the universe are intrinsic, and our naming of these things does not have any effect on what they do. So for example if you took all protons and suddenly they were negative and all electrons were suddenly positive the actual balance of the universe would remain the same. It basically ensures that across the entire universe these concepts remain the same regardless of naming conventions. I’m neither a physicist nor mathematician so hopefully I didn’t butcher that hahah
