Primacy of Space Over Matter: Volumetric Orbital Coherence in the Aether Physics Model — The Kepler Constant as a Substrate Invariant

Orbital regularity in classical mechanics is traditionally interpreted as the result of forces acting on matter, with Kepler’s laws derived from Newtonian dynamics. In this work, that ordering is reconsidered within the framework of the Aether Physics Model (APM). Rather than treating space as a passive background, the model identifies a structured Aether unit as the fundamental element from which spatial coherence and material behavior jointly arise. The Aether unit and its associated substrate are described as co-emerging from a singularity bifurcation in which a primary generative quantity (Gforce) becomes coupled to magnetic charge. This coupling produces a discrete volumetric–chronovibrational structure whose observable projections correspond to measurable physical quantities. Within the Quantum Measurement Units (QMU) framework, volumetric coherence is defined as the ratio of quantum volume to the square of quantum frequency. This quantity represents the persistence of spatial volume through a complete chronovibrational cycle and is independent of inertial mass. As a structural invariant of the Aether unit, it establishes a direct relationship between spatial extent and cyclic completion. Keplerian scaling, expressed as the proportionality between the square of orbital period and the cube of orbital radius, emerges naturally from this relation. In this interpretation, orbital behavior reflects the preservation of volumetric coherence across scales, while Newtonian dynamics describes motion within that underlying structure. The paper further establishes a connection between the Aether unit and electromagnetic propagation through a closure identity that corresponds to the square of the speed of light. This identity demonstrates that volumetric coherence, chronovibration, and propagation are unified aspects of a single substrate structure. Numerical values derived from the QMU framework are shown to be directly consistent with experimentally measured constants, providing a bridge between the model and established physical data. This work supports the interpretation that space is not a passive arena for matter, but an active, structured substrate whose intrinsic properties govern observable dynamics.
