TU-GUT-SUSY V8 - Final Closure: The Quantum Electromagnetic Vacuum as the Sole Physical Entity

TU-GUT-SYSY v8 (December 2025) is the eighth and final iteration of the unification programme initiated in 2025. A single physical entity – the electromagnetic four-potential A_mu in Minkowski vacuum – together with a single ontological principle – degrees of freedom exist only where vacuum entanglement entropy S_ent can still increase – quantitatively derives, with no additional free parameters, the entirety of observed physics: • fermionic matter as topologically stable knotted electromagnetic field lines (Ranada–Faddeev–Niemi–Bilson-Thompson solitons) • nuclear magic numbers and β/α decays as minimal entropic discharge processes • the three gauge interactions as distinct regimes of electromagnetic topology • exact Einstein general relativity outside event horizons • the astrophysical black-hole mass-gap theorem (no stable objects between ~2.2 M⊙ and ~5 M⊙) • a 0.3–0.5 % excess in solar ⁷Be and ⁸B neutrino fluxes (testable 2027–2030 by Hyper-Kamiokande, JUNO, DUNE) • the Big Bounce, galactic dark-matter density ρ_DM ≃ 0.3 GeV cm⁻³, and late-time cosmic acceleration String theory and loop quantum gravity emerge as low-entropy limits of the same vacuum. No extra dimensions, supersymmetry, landscape, or auxiliary fields are introduced.
