Quantum Granodynamics of Spacetime: A Geometric Framework for Gravitational Emergence (updated version)

Abstract

This is an updated, self-contained formulation of Quantum Granodynamics of Spacetime (QGDS), correcting and superseding the previous version. It is written to be read on its own: the full ontology and the corrected mathematics are contained here. QGDS models spacetime as a population of boundary 2-spheres ("grains"), each separating two infinite, mirror-symmetric three-dimensional domains. Grains age; ageing deforms them, suppresses the scale hierarchy inside aged regions (halting local expansion), and drives migration that builds haloes with an age gradient. Principal changes in this version: (i) the effective cosmological term is corrected by a two-population coarse-graining, removing an internal inconsistency and yielding a constant background expansion; (ii) the coherence rigidity is now derived rather than assumed; (iii) the ontology is restated in corrected form; (iv) galactic rotation is reformulated through a resonance model of spacetime propagation with co-moving matter, yielding the realistic rotation-curve form, a natural galactic edge, and a reconciliation with central Keplerian orbits; (v) a conditional derivation of the baryonic Tully-Fisher exponent, an autoregulated model of supermassive cores, and a falsifiable planetary prediction are added. Every result is labelled derived, calibrated, conditional, or open. This is a consolidation of ongoing work, developed with AI assistance under the author's conceptual direction; it is not peer-reviewed, and independent expert review remains necessary.
