TU-GUT-SYSY: Black Holes as Regions of Saturated Electromagnetic Entanglement Entropy – No Interior, No Singularity, Zero Hawking Temperature

Extension of TU-GUT-SYSY v1 (DOI 10.5281/zenodo.17794324). Within the same ontological principle — spacetime exists only where electromagnetic vacuum entanglement entropy can still increase — astrophysical black holes are shown to be finite regions of saturated entanglement (S=S_max). Consequences: no interior spacetime, no curvature singularity, exactly zero Hawking temperature, full unitarity. Key results: no interior geometry beyond the horizon no curvature singularity Hawking temperature exactly zero information preserved on the saturated horizon surface consistent with Bekenstein bound and unitarity Independent theoretical work – Simon Soliman, Rome (Italy) – 2 December 2025
