Standard quantum descriptions treat interference, entanglement, measurement, and no signaling as separate operational rules, yet their shared structural features point to a deeper geometric origin. In this work we identify that origin by developing the analytic exterior: a non‑spatiotemporal analytic domain specified intrinsically by a single analytic direction, a compatibility condition, and a singularity–residue geometry. A relational bundle then supplies the curvature and boundary projections that generate the operational structure of the amplitude calculus. This intrinsic specification requires neither explicit analytic functions nor global coordinates. Within this analytic framework, familiar quantum structures emerge naturally as boundary effects. The Hilbert‑space inner product appears as the boundary pairing induced by residue geometry; analytic flow along the distinguished direction reveals the Schrödinger‑type evolution already encoded in analytic displacement; and boundary evaluation combined with normalization invariance yields the Born rule as the unique probability assignment compatible with the analytic exterior. Interference, entanglement, measurement, and no signaling thus arise not as independent postulates but as geometric consequences of singularities, curvature, and contextual transport. The relational object introduced in [6] is recovered as the boundary value of an analytic‑exterior amplitude kernel, exposing the analytic origin of its interference and measurement properties. The analytic exterior therefore provides a unified, non‑spatiotemporal foundation in which amplitudes, probabilities, and correlations are boundary manifestations of a single underlying analytic geometry. Quantum mechanics emerges as the boundary theory of this analytic structure, offering a unified and conceptually coherent reformulation parallel in spirit to the relational architecture developed in our earlier work. Version 1.1. This revision adds a new subsection clarifying the ontological divergence between the analytic–exterior framework and the standard Lorentzian manifold ontology. The update explains why the analytic exterior cannot arise within the classical spacetime model and introduces the notion of mathematical ontology as a representational constraint. No mathematical results or definitions have been changed.

Quantum phenomena are traditionally described as states evolving in spacetime, yet the zero–proper–time behavior of massless systems points to a different architecture—one in which propagation is not fundamental. Motivated by this observation, we develop a relational framework in which physical processes are represented not as trajectories but as relations between contexts and outcomes. The central object is a relational amplitude function R:B×O→C, organized as a fiber bundle whose slices R_b are selected by experimental contexts. Expressed entirely in standard mathematical terms—probability theory, quantum amplitudes, and fiber‑bundle structure—this relational architecture is precise and unambiguous. Interference, entanglement, and measurement emerge as geometric properties of slice selection rather than as dynamical evolution of a spacetime system. Interference arises when a slice contains multiple coherent contributions; entanglement arises from the non‑factorization of the relational object; and measurement corresponds to a context update rather than a physical collapse. The geometry of zero proper time motivates a shift from a spacetime ontology to a relational one, yielding a unified, non‑spatiotemporal account of quantum phenomena. The result is a structurally simple and conceptually coherent reformulation of quantum mechanics that dissolves long‑standing paradoxes and clarifies the relational foundations from which spacetime events arise. This is version 1.0 of the manuscript. Authors' note (October 2026). This is the original March 2026 manuscript, preserved unchanged as the starting point of an ongoing research program. It is a conceptual proposal, not a set of established results: the framework reformulates the standard quantum formalism in relational language and does not derive it. The proofs of Theorems 5.3 (entanglement) and 5.5 (no-signaling) require additional assumptions that the paper does not state, and claims that the framework “dissolves” the measurement problem or is “complete” should be read as aspirations. The original motivation subsequently led to investigations of geometric, analytic, and measurement-theoretic questions under more explicit assumptions. One such development is The Lorentz-Analytic Exterior: A Conditional Mathematical Framework (Version 2, October 2026), which examines related geometric and analytic structures without relying on the original paper’s zero-proper-time argument as a derivation of quantum mechanics. This later work does not validate the original manuscript’s unsupported claims. https://doi.org/10.5281/zenodo.23400176
Quantum structure in this framework arises from a single analytic kernel defined on the analytic exterior. Boundary wavefunctions are not physical fields but coordinate charts of this kernel, and the familiar canonical operators—Hamiltonian, momentum, position, and angular momentum—appear as boundary projections of one intrinsic analytic generator. Schrödinger evolution becomes the time‑chart expression of analytic flow, while measurement amplitudes correspond to residue components selected by boundary projection. Probability is not an added postulate but the squared residue norm of the projected component, supplied by the invariant residue pairing. A further refinement comes from recognizing that each admissible boundary chart carries its own symmetry group, and each symmetry group forces a unique invariant pairing. The historical operator formalism mixes Hilbert symmetry, Lorentz symmetry, and analytic symmetry, creating the appearance of incompatible dynamical regimes. In this framework, measurement is not merely chart selection but symmetry selection: a boundary projection is well defined only when the symmetry group of the chart aligns with the symmetry of the underlying analytic flow. Symmetry‑compatible charts yield separable boundary expressions, while incompatible charts produce analytic cross‑terms—the geometric counterpart of entanglement. The analytic interval unifies these regimes. When the interval is nonzero, interior analytic structure persists and the boundary receives unitary evolution. When the interval collapses to a null boundary, interior analytic structure is lost and the boundary state becomes static. Because both evolution and collapse are boundary limits of the same analytic flow, the measurement problem dissolves: the apparent duality between unitarity and collapse reflects symmetry misalignment rather than a physical conflict. In this view, quantum mechanics becomes boundary geometry, and its operational content is the shadow cast by the interior analytic kernel. Dynamics, measurement, and probability emerge as coordinated manifestations of a single geometric structure. This is version 1.0 of the manuscript.
This paper argues that amplitude calculus is not an auxiliary quantum construction but the relational coordinate framework forced into existence when the Lorentzian chart collapses at the null boundary. Within the causal domain accessible to a massive probe, the coordinates (x,t) retain clear geometric meaning: worldlines exist, proper time accumulates, and classical trajectories are well defined. At the null boundary these structures fail simultaneously. The invariant interval vanishes, the Lorentzian chart reaches its degenerate limit, and no geometric observable survives. Beyond this boundary the analytic continuation of (x,t) is not spacetime but the diagrammatic overreach of a coordinate system that has exhausted its operational content. Three structural consequences follow. First, null propagation carries no proper time: the boundary is a zero--interval relation, not a limit of motion. Second, the null boundary is not a worldline and admits no geometric in--between. Third, once (x,t) loses operational meaning, only a relational description is possible. In this regime Feynman's amplitude assignments are not postulates but the unique Lorentz--invariant extension assigning complex weights to admissible relational configurations whose coherent aggregate replaces the classical trajectory. Quantum mechanics is thus the relational mathematics demanded by Lorentzian geometry once its coordinates collapse. The non--spacetime domain is not an extension of spacetime but the region where geometry terminates and amplitude begins. This is version 1.1: This version corrects minor structural issues and removes an obsolete appendix; no scientific conclusions are changed. Authors' note (October 2026). This paper is preserved as an exploratory precursor to our later research, not as a validated derivation of quantum mechanics. Several central geometric claims are incorrect: a null interval does not collapse spacetime coordinates to (0,0) or make the Lorentzian metric degenerate, and spacelike-separated events remain part of ordinary spacetime, not a non-spacetime exterior. The further claim that quantum amplitude calculus and complex amplitudes are uniquely forced by null geometry is not established. In particular, the proposed weight e^(−mℓ/ℏ) is a positive real exponential that does not supply the oscillatory relative phases needed for the claimed interference construction; for massless particles (m = 0), this weight is identically one. The original manuscript is retained unchanged as a historical record of the questions that motivated our subsequent investigations. Our later paper, The Lorentz-Analytic Exterior: A Conditional Mathematical Framework (Version 2, October 2026), revisits the geometric and analytic questions under explicit mathematical assumptions, without relying on the coordinate-collapse argument. https://doi.org/10.5281/zenodo.23400176
Horizon Monism proposes a unified theoretical framework in which quantum structure, operational time, and spacetime geometry emerge from finite reference horizons embedded within a single, scale-free relational–interaction totality. Rather than treating spacetime, fundamental time, and quantum probabilities as primitive, the framework investigates their possible reconstruction through finite distinguishability, relational compression, and effective projection structures. The paper establishes a strict mathematical hierarchy of finite-horizon resolutions, deriving monotonic distinction deficits and a directed fine-to-coarse order as a candidate foundation for operational time. This construction is extended to multiple reference horizons through order-preserving transport and conditional shared-blindness theorems. Within a conditionally constructed complex groupoid algebra, the minimal noncommutative effective structure is identified as M₂(ℂ). Projection compression is shown to generate noncommuting effective operators, while smoothly varying projections induce connection curvature. Under specified geometric conditions, this curvature reconstructs the Levi-Civita curvature of an emergent Lorentzian spacetime. Explicit de Sitter and nonlinear Green-spectral constructions provide conditional examples of Einstein geometry and stable nonvanishing projected curvature. A further reconstruction of quantum probability establishes that normalized, context-independent, coarse-graining-consistent effect assignments admit a unique density-matrix representation, recovering the Born rule for pure states. The Principle of Minimal Sufficient Realization is additionally applied to a restricted class of Standard-Model-type representations, yielding conditional minimality results for color, fermion generations, and Higgs structure. The framework distinguishes exact mathematical theorems from conditional physical realizations. Its principal unresolved questions concern the microscopic origin of quantum probability consistency, physical state selection, continuum dynamics, and experimentally distinguishable predictions. Horizon Monism is presented as a mathematical and theoretical research program toward the possible co-emergence of quantum physics and gravitation.
The persistent challenge of unifying quantum mechanics with general relativity is often traced to a series of apparent structural tensions: complex versus real ontology, probabilistic versus deterministic dynamics, linear versus nonlinear evolution, and spectral discreteness versus geometric continuity. We argue that these tensions do not signal a fundamental incompatibility between the theories, but rather originate from surplus structure in the conventional formulation of quantum mechanics. The term unification is used in a structural sense, referring to compatibility of quantum dynamics with classical field theory rather than a modification of general relativity. Beginning from the physically indispensable requirement of matter stability, we prove that the Hamiltonian spectrum can always be shifted to become non-negative. The consequent positivity of energy enforces one-sided temporal frequency support for all physical unitary orbits. Equivalently, all scalar temporal components of physical states arise as boundary values of functions analytic in the lower half of the complex time plane, selecting the Hardy space—or, more generally, analytic tempered distributions—as the admissible solution space. In these spaces, the real and imaginary parts of the wave function are not independent; they are linked uniquely via the temporal Hilbert transform. Hence, the complex structure of quantum mechanics emerges as a representational artifact of an underlying real operator algebra. Building on our earlier work on Unified Quantum Mechanics and the Unified Real Wave Equation, we establish a rigorous proof of exact equivalence between the real-field evolution and the Schr\"odinger equation on the physical subspace. Probabilistic quantities arise naturally as quadratic invariants of analytic signals, rather than as independent postulates. We further show that quantum spectral discreteness arises from operator-theoretic confinement and boundary conditions on a smooth spacetime manifold, and does not imply any fundamental discreteness of spacetime. The resulting framework provides a real-field formulation of quantum mechanics and gravitation, with stability and causality implemented as foundational principles, and demonstrates that the Einstein field equations are compatible with a unified field-theoretic description of spacetime and matter. Extending the same analyticity principle to spacetime geometry, we propose an analytic formulation of the Einstein field equations, from which classical general relativity is recovered exactly as the real projection.
