This note formalizes the Operational Perspective Closure Principle (OPCP), a proposed research criterion for evaluating claims that differences between physical descriptions from different perspectives represent an additional physical degree of freedom. The principle does not introduce a new fundamental law or invariant. Instead, it provides a falsification-oriented test: representational and accessibility differences should not be interpreted as new physics unless an operationally measurable prediction remains incompatible after legitimate transformations of the complete accessible relational structure, including relevant causal restrictions, quantum correlations, gravitational dynamics, measurement structure, and known systematics.

Foundational problems in physics—including quantum measurement, spacetime emergence, gravitational dynamics, nonlocality, the arrow of time, and the status of physical existence—are typically addressed in isolation, via model-dependent extensions or interpretive assumptions. This work proposes a different approach. We introduce a constraint-based framework, the Closure Admissibility Principle (CAP), which specifies minimal structural conditions any physical description must satisfy in order to be globally consistent. CAP is formulated in operational terms, using admissibility of states, recoverability under refinement, and stability of closed records, without assuming spacetime, dynamics, or ontology a priori. We show that enforcing these constraints induces a unifying closure structure on law-space, from which several persistent foundational puzzles are resolved as structural consequences rather than postulates. In particular, collapse is reclassified as record selection, spacetime and gravity emerge only in compressible regimes, General Relativity appears as an infrared universality class rather than a fundamental law, singularities correspond to failures of admissible description, and null (“nothing”) models are excluded as inadmissible fixed points. The framework is explicitly falsifiable via operational and weak-field tests, and its scope and limits are stated precisely. The results suggest that many foundational paradoxes arise not from incomplete dynamics, but from admitting globally incoherent physical descriptions.
The causal closure of the physical is often formulated as the claim that every physical effect has a sufficient physical cause. That formulation leaves two parameters tacit: the domain over which closure is asserted, and the completeness relation—causal, dynamical, or explanatory—that closure asserts of it. Both become unstable when the term physical is indexed to competing quantum ontologies. Wave-function realism treats the quantum state as a field on a high-dimensional space, whereas primitive-ontology, spacetime-state, multi-field, and nomological approaches characterize the fundamental ontology differently. I distinguish spatiotemporal-domain closure from fundamental-physical closure and separate causal closure from dynamical and explanatory completeness. Conditional on wave-function realism, spacetime-restricted closure fails if ordinary spacetime is derivative, but theory-relative closure may remain true once the wave function is counted as physical. The apparent conflict therefore does not establish a trans-domain causal breach. It reveals a formulation dilemma for causal arguments for physicalism: a spacetime-restricted closure principle is too narrow to accommodate serious quantum ontologies, while a theory-relative principle requires an independent, non-question-begging criterion of physicality—and an explicit bridge from dynamical to causal completeness—before it can exclude nonphysical mental causes. Quantum ontology thus converts the familiar problem of characterizing the physical from a deferrable objection into a structural requirement on causal arguments for physicalism, without supporting interactionist dualism. It also explains why appeals to Hilbert space, the PBR theorem, the Born rule, or Bohmian guidance cannot by themselves yield the stronger conclusion.
This paper introduces Axiom 0, a minimal foundational principle for physical reality: the impossibility of any globally closed description of the total correlational structure. Rather than postulating space, time, dynamics, locality, or physical laws as primitive, the framework assumes only: (i) the existence of a correlational structure, (ii) the structural impossibility of complete self-closure, and (iii) consistency under partial comparison. From these ingredients, the paper shows how: physical laws emerge as stabilizing regularities of incomplete descriptions, time, dynamics, and geometry arise as effective, regime-dependent structures, irreversibility follows from projection and information loss, and why no description can be both exact and globally complete. Non-closure is treated as an ontological constraint, not as epistemic ignorance or observer dependence. Physical reality exists precisely because complete closure is impossible, independently of observation or modeling. The paper does not attempt to replace existing physical theories or derive numerical constants. Instead, it provides a structural foundation within which effective physical theories (quantum, classical, relativistic, and open-system regimes) can be consistently understood as emergent and domain-limited. This work is intended as a conceptual and structural foundation for correlational and relational approaches to fundamental physics, clarifying the origin of laws, dynamics, and physical regularity without invoking additional ontological postulates.
Central thesis: Quantum theory contains stable closure without universal completion. Quantum field theory repeatedly resists the classical assumption that every physically meaningful structure must correspond to an independently complete object. A quantum state can be definite relative to one observable while remaining unresolved relative to another; separated alternatives can retain phase relations and later interfere; composite systems can possess globally definite relational structure without factorizing into independently complete subsystems; gauge-related field configurations can represent a single physical state; effective descriptions depend systematically on scale; and local field degrees of freedom need not correspond to independently realizable asymptotic particles. This paper investigates whether these apparently different structures admit a common representation as forms of partial closure. A closure is defined as a physically meaningful stabilization or equivalence relative to a specified context, probe family, observable algebra, quotient, scale, or asymptotic condition. It is partial when stable disclosure exists while additional physically relevant structure remains latent, relational, global, scale-dependent, or otherwise outside that closure. The framework distinguishes redundant fibers from latent physical fibers through a future-distinguishability criterion and introduces reclosure for later sensitivity to information not exhausted by an earlier closure. Interference becomes phase-sensitive reclosure; incompatible measurements instantiate noncommuting closure; entanglement instantiates nonfactorizable closure; contextuality becomes a failure of local closures to assemble into one global classical assignment; gauge symmetry becomes quotient closure; renormalization becomes scale-relative effective closure; confinement exemplifies asymptotic closure restriction; and Berry, Wilson, and flavor-cycle invariants exemplify closed relational cycles retaining invariant memory. Two restricted theory-space applications are developed: a one-generation hypercharge calculation in which Yukawa invariance and anomaly cancellation fix relative hypercharges up to overall normalization, and a minimal representation reconstruction under explicit low-dimensional and minimality assumptions. The resulting Typed Quantum Partial Closure Representation Theorem is a representation theorem rather than a derivation theorem. The framework is therefore presently a unifying reconstruction program whose decisive future test is whether closure principles can generate restrictions or predictions not already contained in the formalisms they reorganize. Keywords: quantum field theory; partial closure; reclosure; gauge symmetry; effective field theory; entanglement; contextuality; confinement; asymptotic states; anomaly cancellation; flavor mixing
Modern physics provides empirically complete and highly successful descriptions of local dynamics. General relativity specifies the causal evolution of spacetime geometry, and quantum mechanics specifies the unitary evolution of states. Despite this success, both frameworks leave implicit a foundational question: when a dynamically admissible configuration can be regarded as physically realized as part of a coherent world. This work introduces a minimal, non-dynamical realization criterion that formally closes this gap. Physical realization is defined as a global, temporally organized admissibility condition constrained by relativistic causality. The criterion does not modify any local equations of motion, introduce new forces, fields, particles, or degrees of freedom, nor alter the mathematical structure of existing theories. Instead, it identifies realization as an organizational condition required for dynamical solutions to become physically instantiated. A minimal causal bound T = L / c is shown to follow directly from relativistic causal structure, implying a finite organizational time for global coherence across a spatial extent L. The associated inverse scale Ω = c / L is clarified as a structural constant rather than a dynamical frequency: it has no oscillatory interpretation, carries no energy, and does not represent a physical process. Its role is purely limiting—it marks the minimal global temporal orientation required for realization to persist. Within this framework, classical gravitational optics, delayed global geometric organization, and quantum outcome realization arise as direct consequences of the same realization criterion. The contribution of this work is exclusively structural: it makes explicit a condition already implicit in successful physical theories and provides a formal closure without extending or revising their dynamics. This paper concludes a broader research program on temporal realization, gravitational organization, and global coherence by isolating realization as a necessary condition for physics to describe a world at all.
Abstract This paper proposes a minimal formal criterion for physical entity. It does not attempt to derive quantum mechanics, general relativity, quantum gravity, or any empirical prediction. Its aim is narrower: to ask what formal conditions must be satisfied before a structure may be treated as a physical entity at all. The starting point is the principle of stable distinguishability: a physical theory is possible only where distinctions can be made and re-identified under admissible change. From this requirement, the paper develops a constraint-primacy framework in which no particle, field, spacetime point, state, measurement, or observable is assumed as primitive. The formal layer consists of tokens, admissibility, and a closure operator defined on the full power set of tokens. Identity is reconstructed as closure-equivalence. Boundary is defined non-spatially as first-entry dependency, and core is defined non-circularly as a closed non-boundary substructure. A physical entity is then defined as a boundary-stable closure-core equivalence class: a closed admissible structure whose core closure-identity is preserved under relevant boundary-mediated extensions. The paper uses familiar mathematical tools, including closure, equivalence, isomorphism, and invariance; its proposed contribution is not those tools themselves, but the ontological criterion they support.
