The so-called collapse of the wave function is still regarded as one of the central unresolved problems of quantum mechanics. This paper argues that this problem does not stem from an incomplete physical theory, but from a categorical misaddressing. The collapse is usually understood as a physical process that takes place within time and should, in principle, be further analyzable in dynamical terms. This assumption, however, is itself part of the problem.On the basis of an ontological distinction between possibility and factuality, it is shown that the collapse is not a process, but an irreversible constriction of an ontological space of possibility. Measurement is not understood as an epistemic act, but as object-making: a coercion toward objectivity through which possibility is excluded and the world is fixed to a single factual continuation. The collapse does not mark a transition between states, but a boundary act at which the language of processes loses its validity.In this understanding, the collapse is not an event in time, but a generator of time direction. Time appears as the trace of irreversible constrictions, not as a presupposed background parameter. The position advanced here thereby explains why the collapse cannot, in principle, be mechanistically explained without introducing additional entities or dynamics.The paper proposes that the measurement problem should no longer be treated as a question of a hidden mechanism, but rather as a boundary phenomenon in which the ontological presuppositions of physical description themselves become visible. This shifts the focus from processes and mechanisms to conditions, regimes, and boundaries of world-formation.

The measurement problem of quantum mechanics is predominantly treated in contemporary foundations research as an unresolved problem of dynamics or ontology. Accordingly, dominant solution approaches aim either at additional collapse mechanisms (e.g., GRW-type models), at ontological branching (Many-Worlds interpretations), or at an information-theoretic reinterpretation of state and measurement.The present contribution advances a different thesis. It shows that, despite their methodological differences, these approaches share a common categorical presupposition: they treat the transition from possibility to facticity as an intra-worldly describable occurrence—whether as a dynamical process, an ontological splitting, or a state update. It is precisely this presupposition that is called into question here.Starting from an ontological distinction between possibility and facticity, it is argued that measurement cannot be understood as a temporal event within an already structured world. Rather, it marks a boundary at which temporal, processual, and informational descriptions lose their applicability. The transition to objectivity is therefore not an explainable event, but an irreversible restriction of the space of possibility, through which world becomes factically binding in the first place.Against this background, dynamical collapse models, Many-Worlds interpretations, and information-theoretic ontologies are comparatively analyzed. The aim is not a refutation of these approaches, but a precise boundary determination: it is shown in what way they each provide formally successful answers to partial aspects of the measurement problem, while at the same time presupposing the categorical status of facticization that they claim to explain.The contribution does not understand itself as an alternative interpretation of quantum mechanics, but as an ontological clarification of its domain of validity. It proposes that the measurement problem should no longer be treated as the search for a hidden mechanism, but as an indication of a structural boundary of physical description itself.
Operatoric Research CorpusStudies in World-Formation Section I Ontology and Physics Volume 2 The Ontological Limits of Physical ExplanationMeasurement, Collapse and Boundary Phenomena in Quantum Physics This volume brings together a series of contributions on the ontology of fundamental problems in physics, in particular the measurement problem of quantum mechanics, the collapse of the wave function, the relationship between quantum mechanics and relativity theory, as well as boundary phenomena such as black holes, renormalization, and vacuum energy. The point of departure of these investigations is the thesis that numerous paradoxes of modern physics do not primarily result from insufficient physical theories, but from a categorical misaddressing. Transitions that concern the very conditions of world stability—especially the transition from possibility to facticity—are often interpreted as dynamical processes within an already stabilized world. This gives rise to explanatory programs that attempt to bridge this boundary by means of additional mechanisms, ontologies, or informational structures. The texts collected in this volume pursue an alternative strategy. They understand the so-called collapse of the wave function not as a physical process, but as an irreversible constriction of a space of possibility through which objectivity and the direction of time first emerge at all. The concept of indimergence designates the boundary act in which possibility passes into facticity without itself being describable as an event within the world. On the basis of this determination, central approaches in the foundations of quantum mechanics—particularly dynamical collapse models, Many-Worlds interpretations, and information-theoretic ontologies—are comparatively analyzed. It becomes evident that, despite their differences, they share a common presupposition: the assumption that the transition from possibility to facticity must itself be explicable within physical description. The contributions in this volume instead propose to read the measurement problem and related paradoxes as indications of structural limits of physical description. From this perspective, other fundamental problems—such as the tension between quantum mechanics and relativity theory, the information paradoxes of black holes, or divergences in field theory—no longer appear primarily as unsolved technical puzzles, but as boundary phenomena of world formation itself. The volume therefore does not present itself as an alternative physical theory, but as an ontological clarification of the conditions under which physical theories are able to describe a world at all.
This work re-examines the long-standing interpretation problems of quantum mechanics—measurement, collapse, probability, irreversibility, the observer, and entanglement—not by proposing a new physical theory, but by relocating the structure of the questionsthat have framed these problems. The paper argues that many interpretational tensions arise not from the formalism itself,but from how concepts such as measurement, state, time, and probability have beenpositioned within the explanatory structure. Measurement is treated not as a privilegedphysical event, but as a structural condition associated with record formation.Collapse is interpreted as the unavoidable fixation of perspective once such records exist,rather than as a dynamical process added to the theory. Time is relocated from a global background parameter to a local phenomenon that appearsonly while interactions remain unresolved. Irreversibility is accordingly understoodnot as a fundamental temporal direction, but as the closure of a perspective.Probability is reinterpreted not as future uncertainty or intrinsic randomness,but as a structural summary of how multiple interactions close in the present. The observer is not treated as an external subject or agent, but as a boundary positionat which correlations between system and environment become fixed.Entanglement is understood not as nonlocal influence, but as the manifestation ofan indivisible whole structure that cannot be decomposed into independent parts. This work does not modify the mathematical formalism or predictive success of quantum mechanics.Instead, it constrains the interpretational space by showing how different questionsabout the same formal results generate persistent disagreement.The contribution is therefore conceptual rather than predictive,and is intended as a foundation for further discussion in quantum foundationsand phase-based theoretical frameworks.
The collapse of the wave function remains one of the deepest puzzles in quantum mechanics. The Schrödinger equation is unitary and time-reversal symmetric, yet measurement requires an additional postulate that is neither—and we have no physical explanation for why. Existing interpretations either deny that collapse is real (Many-Worlds), treat it as purely subjective (QBism), or add stochastic noise by hand without deriving it from fundamental principles (GRW, CSL). We demonstrate that collapse is a real physical process requiring fundamentally irreversible dynamics. No purely unitary, time-symmetric theory can account for the objective suppression of macroscopic superpositions—irreversibility must be built into the dynamics from the start. We introduce a minimal extension of quantum mechanics through coupling to a universal scalar field (the I-field) governed by an explicit time-asymmetric field equation. Collapse emerges objectively through deterministic dissipative dynamics, with no reference to observers, measurement devices, or stochastic noise. By integrating out the I-field degrees of freedom, we derive effective Lindblad dynamics for quantum systems. The collapse rate scales quadratically with system mass, ensuring microscopic quantum coherence remains intact while macroscopic superpositions are dynamically suppressed. Unlike stochastic collapse models (GRW/CSL), the mechanism is deterministic and produces no spontaneous heating. Unlike gravitational collapse proposals (Diósi-Penrose), it provides explicit field equations rather than heuristic arguments. Unlike environmental decoherence, the irreversibility is fundamental rather than effective. The theory respects relativistic causality and makes testable predictions for current and near-future experiments in matter-wave interferometry, optomechanical systems, and molecular interferometry. Observation of mass-dependent decoherence without accompanying stochastic heating would provide strong evidence for the I-field mechanism. The framework establishes irreversibility as a fundamental interaction rather than an emergent phenomenon, providing a unified physical origin for both wave function collapse and the quantum arrow of time.
We present an ontological and dynamic derivation of wave function collapse within the context of General Relativity formulated as a Quantum Theory (GRQT), a formulation that maintains ontological realism and conceptual continuity with General Relativity. Starting exclusively from the discrete geometric structure of spacetime and its fundamental elastic properties, we demonstrate that collapse constitutes neither an additional postulate of quantum mechanics nor an external phenomenological effect, but emerges as a necessary consequence of the requirement for geometric consistency in the temporal update of the causal lattice. We show that quantum superpositions of massive systems imply geometric bifurcations of spacetime, associated with incompatible metrics in the transition between successive simultaneity slices. The energy identified in Objective Reduction theories as gravitational self-interaction energy is reinterpreted, in GRQT, as the elastic deformation energy of the lattice, governed by the fundamental geometric impedance α. We derive a quantitative criterion for the viability of temporal evolution and a closed-form expression for the characteristic collapse time, without introducing free parameters. Wave function collapse thus arises as the physical process by which spacetime eliminates geometric ambiguities incompatible with the unique definition of the subsequent slice, preserving the topological continuity of the causal manifold. The boundary between quantum and classical regimes becomes quantitative and derived, resolving the measurement problem in strictly geometric terms. The formulation maintains ontological realism, conceptual continuity with General Relativity, and provides explicit experimental predictions in mesoscopic regimes.
Quantum Incompleteness presents an ontological interpretation of quantum mechanics in which physical systems are objectively under-specified prior to irreversible interaction. The theory rejects hidden variables, parallel worlds, and observer-dependent collapse, proposing instead that definite outcomes emerge through irreversible information-theoretic constraints that physically exclude alternatives. The wavefunction is treated as a real but non-material structural entity that defines the space of admissible outcomes rather than pre-existing values. Measurement, entanglement, classical definiteness, and the arrow of time are unified under a single completion mechanism grounded in thermodynamic irreversibility, while preserving the standard mathematical formalism of quantum mechanics. This work is empirically equivalent to standard quantum theory and is intended as a foundational clarification of what quantum mechanics describes rather than a modification of how it computes predictions.
