Structured Space Theory (SST), Version 3 presents a discrete geometric-gravitonic framework in which space is modeled as a lattice of G-particles and immutable G-holes, with dynamics expressed through graviton density (GD/gD), graviton frequency (GF/gF), and ripple-tension propagation. Title and terminology update. Versions 1–2 were published under Super-Space Theory. Version 3 adopts the title Structured Space Theory (SST) and revises several terms to reduce ambiguity with terminology already established in mainstream physics and mathematics. In particular, “Super-Space / Sub-Space” are replaced by Super-Structure / Sub-Structure. The macroscopic label “g-Force” is retired to avoid confusion with standard G-force usage; macroscopic effects are instead described through the Macroscopic Ripple Field (RF), while gRF remains the microscopic graviton ripple field. Null-Space is retained. Major technical update. Version 3 adds an explicit treatment of Electromagnetic Phase Dynamics within the traversal/reintegration framework (new §4.5), including a continuum-limit formulation in which coherent transverse phase displacement supports a vacuum wave equation and a Maxwell-correspondence mapping. This connects electromagnetic behavior more directly to the same lattice-propagation invariant used elsewhere in the theory. Additional updates in v3 include notation standardization; clarification of the role of κ_geo for the tetrahedral-octahedral lattice and associated density-spacing relations; consistent enforcement of baseline vs local notation (GF/GD vs gF/gD); retention of the propagation invariant under the manuscript’s propagation-mode convention; revision and expansion of the emergent-constants pathway (including c, h, and Planck-scale relations); and stronger linkage between SST parameters and observational constraints, with emphasis on measurable quantities and falsification criteria where stated.
