In other words, what type of mapping (bijection, surjection; homeomorphism, isomorphism, or... in a sense, automorphism) operates between “observable physical space-time” and “semantic space”?
I profess the concept that any object - regardless of the degree of subtlety of the matter that forms it - carries within itself a fractal grain of the Absolute. Thus, each object in relation to each object (both another object and itself) has meaning. That is, “observable physical space-time” is a subspace of semantic space.
Spacetime is defined by its symmetries, so the question is what are the symmetries that are assumed to leave ``semantic space'' invariant.
The rotational symmetry of a ferromagnet or the gauge symmetries of the Standard Model are examples of ``internal symmetries'', that don't act on the spacetime coordinates.
