Formal Closure at the Black Hole Horizon: The Completion of Physical Description (TSTT V4.0)

Formal Closure at the Black Hole Horizon: The Completion of Physical Description (TSTT V4.0) Takayuki TakagiIndependent Researcher, Saitama, JapanORCID: 0009-0003-5188-2314 DOI: 10.5281/zenodo.18206602 Abstract This work argues that black holes represent not a breakdown of physical law, but the formal closure of physical description itself. Within the framework of Theological–Structural Transposition Theory (TSTT), a black hole is the regime in which the formal boundary becomes fully opaque: all admissible dynamical descriptions terminate at the horizon, and only boundary-defined observables remain. TSTT V2.0 identified grammatical silence in tritium beta decay, where transitions proceed with maximal economy and no additional structure is invoked. TSTT V3.0 identified formal saturation in neutron star cooling, where all admissible channels are exhausted and no further dynamical agency can manifest. TSTT V4.0 completes this sequence: in black holes, the grammar of physical description itself becomes unobservable. There is neither silence nor saturation, but closure. The black hole information paradox is reframed: information is neither destroyed nor preserved, neither hidden nor recovered—it is completed. The paradox dissolves not by resolution, but by recognizing that the category of information no longer applies beyond the formal boundary. Mass, charge, and angular momentum are not remnants of hidden dynamics; they are epitaphs—the last readable inscriptions of a system whose internal grammar has closed. This work proposes no theory of quantum gravity, no modification of General Relativity, and no information-recovery mechanism. Physics does not fail at black holes. It finishes. Keywords: black hole, information paradox, formal causation, event horizon, TSTT, theoretical physics, philosophy of physics Overview This repository contains the final installment of the Theological–Structural Transposition Theory (TSTT) series. V4.0 addresses black holes not as anomalies or breakdowns of physical law, but as the formal closure of physical description itself. Physics does not fail at black holes. It finishes.

In V4.0: Information is neither destroyed nor preserved Information is neither hidden nor recovered Information is completed The paradox dissolves not by resolution, but by recognizing that the category of information no longer applies beyond the formal boundary.
