The DIVE Model: A Unified Dark Sector via Quantum Decoherence and its Testable Predictions on Galactic Dynamics

The missing mass problem has driven decades of search for collisionless dark matterparticles, yet direct detection efforts have yielded null results. In this paper, we propose aparadigm shift: the Dynamical Interaction-driven Vacuum Event (DIVE) model. We positthat dark matter is not an independent elementary particle, but rather the localized macro-scopic rendering of the quantum vacuum’s effective mass, dynamically triggered when thebaryonic gauge flux crosses a critical holographic threshold (F ≥ Fc). At the galactic scale,the DIVE model naturally reproduces the empirical successes of the Tully-Fisher relationand modified Newtonian dynamics purely from vacuum state reduction. At high-energyastrophysical scales, thermodynamic vacuum screening elegantly explains the spatial off-set in the Bullet Cluster, while localized vacuum annihilation accurately accounts for theGalactic Center GeV Excess. Furthermore, through high-resolution 2D N-body simulations,we demonstrate that the macroscopic Cosmic Web dynamically emerges from a pure bary-onic plasma without pre-existing dark matter seeds. Ultimately, to provide a definitive andempirically testable falsification boundary, we computationally predict a novel kinematicsignature: local flux obstruction by galactic dust lanes will quench the vacuum render-ing, inducing a measurable 13% rotation curve asymmetry and a distinct orbital velocity‘crossover’. This provides a clear, purely internal mechanism to empirically validate theDIVE framework in upcoming high-resolution surveys
