Our supposition of zero is that it’s inherently nothing - a null. But I think it can also be explained as both a point of equilibrium and the infinity. All things in nature has a centric and balancing point of some opposing factors like the Newton’s Third Law of Motion, Archimedes’ balancing principle, and electric charges. Numeric zero would simply be an extension of this where it is a net-zero sum of all Real numbers. By extension, the second interpretation can be explained using the first interpretation, where zero is an overloaded, infinitely recursing net-zero sum.
