This document is part of the Informational Mechanics (IM) framework and is published in the IM-D (Core Physics) series within the IM v0.3 corpus. The paper addresses the black hole information problem by re-examining the physical meaning of information under extreme gravitational collapse. Rather than treating the problem as a conflict between information loss and information preservation, the analysis argues that both alternatives presuppose the continued admissibility of operator-defined information in regimes where the structural conditions required to define information may no longer hold. Within Informational Mechanics, information is defined only where admissible structure exists: stable distinctions, persistent identities, and reproducible correlations supported by operational comparability under disturbance. Under gravitational collapse and evaporation, these conditions fail. In such regimes, the operators required to define, track, or recover information cease to be physically implementable, rendering questions of loss or preservation physically undefined rather than false. This admissibility-based perspective reframes the black hole information paradox without introducing new dynamics, modifying quantum mechanics, or invoking observer-dependent ontologies. Formal unitarity may remain intact at the level of mathematical description, while the physical content of information-bearing correlations becomes inadmissible. The firewall paradox is treated as a direct corollary, arising from an inadmissible demand for simultaneous operator-defined access to interior, exterior, and horizon-spanning descriptions. The paper synthesizes and clarifies the distinct insights associated with Penrose, Hawking, and Susskind by showing that each applies within a different admissible regime. Black holes are treated as local admissibility boundaries, analogous to cosmological regime boundaries analyzed in Regime Condensation Cosmology (IM-D002). This work introduces no new dynamics, models, or experimental fits. Its contribution is disciplinary and structural: to clarify the regime conditions under which “information” is physically defined, and to reclassify the paradox as an inadmissible demand for simultaneous operator-defined access across incompatible regimes.

This document is part of the Informational Mechanics (IM) framework and is published in the IM-D (Core Physics) series within the IM v0.3 corpus. The paper analyzes the status of unitary evolution when physical description crosses regime boundaries. While unitary time evolution is well-defined within admissible geometric regimes, its extension across inadmissible regime transitions is shown to lack structural derivability unless operator-defined state continuity can be physically implemented. Building on the regime-limited validity arguments of IM-C003 and the operator criteria formalized in IM-E001, the paper demonstrates that global unitarity cannot be presumed as an ontological default. Instead, unitary evolution must be treated as a regime-bound statement whose validity depends on the continued implementability of the operators required to define and compare physical states. The analysis introduces no new axioms, dynamical models, or empirical fits. Its contribution is structural: to clarify the admissibility conditions under which claims of global state continuity remain scientifically meaningful and to show why cross-regime extrapolations of unitarity constitute a category error when operator-access fails. Downstream empirical and simulation-based evaluation of regime transitions is addressed in the IM-G series.
This document is part of the Informational Mechanics (IM) framework and is published in the IM-I (Reviews & Syntheses) series within the IM v0.3 corpus. The paper synthesizes recent IM work on universality and regime-limited validity to clarify the status of quantum mechanics under admissibility constraints. Rather than proposing modifications to quantum theory, it analyzes the conditions under which claims of global validity remain scientifically meaningful. Drawing on IM-C003 (regime-limited universality), IM-E001 (operator criteria for universality), and IM-D005 (structural non-derivability across regime transitions), the document shows how quantum-mechanical unitarity and state evolution must be understood as regime-bound statements whose validity depends on operator-defined implementability and cross-regime comparability. The paper introduces no new axioms, models, or empirical results. Its purpose is clarificatory and integrative: to provide a coherent account of how quantum mechanics retains full validity within admissible regimes while avoiding unwarranted global extrapolation beyond operator-defined structure.
What if the black-hole information problem begins with the wrong primitive? Rather than treating information as a substance that must be stored, hidden, destroyed, or recovered, this research reframes the problem around Realised Physical Distinguishability (RPD): the physically actual capacity to discriminate between alternative states by operations performed with finite energy, finite time, finite resolution, and access to a specified algebra of observables. Two states belong to the same operational class when no admissible measurement can distinguish them above a fixed threshold. The resulting structure is RPD(M) := 𝒮(M) / ~, while information appears only as the derived quantity I(M) := log₂ |RPD(M)|. From this perspective, a black hole is not primarily a container of inaccessible bits. It is a horizon-mediated transformer of distinguishability classes. The event horizon changes which operations remain available to an exterior observer. Because the exterior algebra 𝒜_ext is only a restricted part of the global algebra, states that remain globally distinct may become operationally indistinguishable from outside. This produces the observer-dependent quotient RPD_𝒜(M) := 𝒮(M) / ~_𝒜 and motivates a time-dependent transformation of the form T_H(t): RPD_𝒜₁(M,t₁) ⇝ RPD_𝒜₂(M,t₂). Horizon crossing therefore need not mean the destruction of physical distinctions; it may instead mean their removal from one accessible channel and their redistribution into others. The paper identifies three candidate channels: null-wave delocalisation, in which causal structure and redshift carry distinctions beyond ordinary localisation; gravitational-geometric re-expression, in which mass, angular momentum, multipole structure, gravitational waves, and memory preserve aspects of the preceding configuration; and quantum-radiative redistribution, in which correlations among Hawking radiation, residual geometry, and possible topological sectors may progressively restore exterior-accessible distinctions. Unitarity is consequently interpreted not as the miraculous reconstruction of a former macroscopic object, but as the possible lawful continuity of distinguishability through changing physical forms. The framework is developed on a compact or effectively compact S³ carrier, while Schwarzschild-, Kerr-, or de Sitter-type horizons remain local models of operational inaccessibility. A quantitative selector branch compares the causal-spectral capacity of S³ with explicitly declared external ceilings such as Bekenstein or holographic bounds. Its central filter is Σ_grav^(P) = min(1, B_ceil / (b_P Γ_R(T) N_P(ε))), where Γ_R(T) describes the causally accessible fraction of the compact carrier and N_P(ε) counts distinguishable spectral modes at resolution ε. In the local regime, a notable cancellation gives B_causal^(P) ~ (2b_P C_P / 3π)(cT/ε)³, removing the carrier radius R from the leading term and producing the threshold relation (ε_*^(P))³ = (2b_P C_P ln 2 / 3π²)cTℓ_P². This selector is not proposed as a force law or a complete microscopic theory; it is a disciplined diagnostic of how causal access, spectral resolution, and gravitational ceilings constrain physically realisable distinctions. The work further introduces topological horizon capacity as an open research object and explores whether holonomy, Berry phases, the Hopf fibration S¹ → S³ → S², and sectors labelled by Q_H ∈ ℤ could protect or transform distinguishability during collapse and evaporation. No final solution of the black-hole information paradox is claimed. The research contribution is a sharper foundational question: not “Where are the bits?”,but “Which physical differences remain realisable, for whom, through which channels, and under what geometric and topological limits?”
This document is part of the Informational Mechanics (IM) framework and is published in the IM-D (Core Physics) series within the IM v0.3 corpus. The paper develops a structural account of quantum entanglement under regime-limited admissibility constraints. Rather than introducing new dynamics, hidden variables, or collapse mechanisms, it analyzes entanglement as a consequence of structural non-factorizability arising from bilinear composition and tensor minimality within admissible operator regimes. Building on IM-B004 (tensor minimality), IM-C004 (regime-conditional structural principles), and IM-E004 (operator-defined outcome weights), the analysis shows that Bell-inequality violations constrain classical factorizability assumptions without implying superluminal signaling or ontological inseparability. The account preserves the formal structure of quantum mechanics and treats locality and no-signaling conditions as operator-level constraints. No new axioms, empirical fits, or modifications to established physical theories are introduced. The contribution is classificatory and structural: it clarifies how entanglement and Bell correlations emerge within regime-bounded admissibility while explicitly identifying the structural assumptions under which the account would require revision.
This document is part of the Informational Mechanics (IM) framework and is published in the IM-E (Measurement & Operators) series within the IM v0.3 corpus. The paper analyzes the physical status of the quantum-mechanical wavefunction under admissibility constraints. Rather than adopting an ontological position (ψ-realism or ψ-epistemicism), the analysis evaluates when the wavefunction carries operator-defined physical content within a declared quantum-mechanical regime. Within Informational Mechanics, physical content is defined only where operator-implementable observables, stable invariants, and regime-bounded comparability are available. The wavefunction is therefore treated as a regime-defined representational object whose physical meaning depends on the continued admissibility of the operators required to define and compare its associated observables. The paper introduces no new axioms, collapse models, hidden variables, or empirical fits. Its contribution is structural and operational: to clarify when statements about the wavefunction are scientifically meaningful and when they extend beyond operator-defined structure.
This clarification addresses a common assumption in modern physics: that information conservation necessarily requires unitary, reversible evolution within spacetime. Within the Communication Matrix framework, information conservation is instead treated as a global, non-geometric constraint on admissible configurations rather than a requirement imposed on geometric dynamics. The note introduces the concept of a continuous substrate-level ledger, in which information is recorded contemporaneously with geometric realization. Each probability-bubble collapse is immediately registered as a constraint update, without storing retrievable histories, timelines, or microstates. Conservation is therefore a continuous process tied to state actualization, not a deferred archival event or end-state “download.” By explicitly separating substrate-level conservation from spacetime-level unitarity, the note demonstrates how geometric evolution may become non-unitary and irreversible during regime transitions—such as collapse, saturation, or black-hole formation—without violating information conservation. The black-hole information paradox is shown to arise from a category error: conflating global conservation with local geometric reversibility. This document is intended as a focused clarification rather than a new dynamical proposal, and is compatible with standard quantum mechanics within its regime of validity.
