TMD: Why Black Holes Have Zero Orientational Spin — The Global Half‑Flip of the Event Horizon as a Macroscopic Analog of the Proton Half‑Flip

This work presents a unified orientational mechanism within Triadic Mesh Dynamics (TMD) that explains both the spin‑zero state of the proton’s third‑layer bonding configuration and the orientational properties of black hole horizons. In TMD, spin is not an abstract quantum number but the orientational moment of triads. When an entire layer of triads undergoes a collective 90° half‑flip, orientational moments cancel and a spin‑zero state emerges. I show that the same mechanism applies at the event horizon of a black hole. The extreme orientational gradient forces the horizon layer into a global half‑flip, locking orientational flow and producing a macroscopic spin‑zero state independent of the black hole’s rotation. Because triads have finite thickness and do not align edge‑to‑edge, the stacked configuration generates orientational seams—natural points of weakened half‑flip where triads can escape. These seams, together with polar escape corridors and accretion‑disk disturbances, determine the structure of emissions around black holes. The resulting anisotropic emission maps, local maxima, and relativistic jets observed by the Event Horizon Telescope (EHT) arise directly from the orientational geometry of the global half‑flip. The work demonstrates that isotropic Hawking radiation is mechanically incompatible with TMD and that the horizon’s orientational spin is necessarily zero.
