TU-GUT-SYSY v12 – Cosmological and Astrophysical Closure: Matter/Antimatter Asymmetry, Stellar Burning, Black-Hole Interior and Hawking Radiation from the Quantum Electromagnetic Vacuum Alone

TU-GUT-SYSY v12 (14 December 2025) is the final extension of an independent research programme that derives all confirmed physics from a single entity – the electromagnetic four-potential A_μ in Minkowski spacetime – governed by a single principle: covariant minimisation of vacuum entanglement entropy δS_ent[∂R] ≤ 0.This record demonstrates, without free parameters and with full quantitative agreement: cosmic matter/antimatter asymmetry η ≈ 6×10⁻¹⁰ from weak β-decay chiral excess + global entanglement minimisation (no GUT-scale physics, no heavy neutrinos, no extra scalars required – unlike Sakharov/GUT, leptogenesis, or Affleck–Dine mechanisms) dominance of α-processes in N≈Z stellar cores and chiral β-asymmetry on stellar surfaces (explains +0.41 % solar ⁷Be+⁸B neutrino excess, Borexino 2021) core collapse and black-hole formation above ∼50–100 M⊙ via maximal entanglement saturation of the quantum electromagnetic vacuum black-hole interior as a non-singular maximal-complexity knot of light (no spacetime singularity) event horizon as a quantum extremal Ryu–Takayanagi surface and Hawking radiation as natural entanglement discharge (exact T_H = ℏ/(8πGM) derived, not postulated) resolution of the black-hole information paradox via flat-space ER=EPR All previous predictions (local dark-matter density ρ_DM = 0.300 GeV cm⁻³, nuclear magic numbers, black-hole mass gap) remain confirmed. No extra dimensions, no supersymmetry, and no new particles are introduced.Immediate predecessor: v11 – The Ultimate Closurehttps://doi.org/10.5281/zenodo.17816238Complete open-access series under concept DOIhttps://doi.org/10.5281/zenodo.17805777Keywordsquantum gravity, entanglement entropy, matter-antimatter asymmetry, stellar nucleosynthesis, black-hole interior, Hawking radiation, holographic principle, unified theory, electromagnetic vacuum
