A Unified Framework for Relativity and Quantum Mechanics via Delayed Realization

Abstract

This work presents a unified theoretical framework that aims to bridge relativity and quantum mechanics through a single structural principle: delayed realization. Instead of assuming spacetime, time evolution, or quantum states as primitive entities, the framework introduces a pre-geometric definability network in which relational differences are initially undefined and become stabilized through nonlinear dynamics. The emergence of spacetime is then reinterpreted as the stabilization of definable differences, while the present is not given a priori but selected via delayed consistency over histories. Within this formulation, quantum phenomena arise naturally when multiple realization candidates coexist, producing interference structures governed by a variational principle. In the low-defect limit, the framework recovers effective relativistic geometry and field-theoretic behavior, including emergent gravitational curvature and gauge structures. A central contribution of this work is the formulation of a unified definability action, combining stabilization, curvature minimization, delayed consistency, and informational structure into a single variational framework. Under appropriate coarse-graining, this action yields structures consistent with Einstein field equations, quantum amplitudes, and gauge invariance as different regimes of the same underlying mechanism. This paper does not claim a fully closed mathematical unification of all physical sectors. Instead, it provides a coherent structural framework in which spacetime emergence, present realization, quantum probability, and effective field dynamics are organized as manifestations of a single principle. The framework is intended as a foundational step toward a deeper unification of physics, where time, geometry, and probability are not assumed, but emerge from the stabilization and realization of definable relational structures.

Delayed Definability Field Theory: A Unified Framework for Relativity and Quantum Mechanics via Delayed Realization

Trinity Labo

This work presents a strengthened formulation of Delayed Definability Field Theory (DDFT), a unification architecture in which spacetime geometry, quantum probabilistic structure, and gauge dynamics emerge from a single pre-geometric principle: the stabilization and delayed realization of definable relational difference. The framework is designed to address four major weaknesses that commonly limit foundational unification attempts. First, the definability field is no longer treated as a symbolic placeholder, but is defined on a measurable relational substrate as a bounded symmetric field on pair space. Second, the continuum problem is no longer hidden inside an unspecified coarse-graining map; instead, the theory introduces discrete closure geometry on simplicial approximants, a Regge-type closure-gravity action, and a controlled continuum route under bounded-defect and Γ-convergence assumptions. Third, the quantum sector is strengthened by replacing a purely schematic probability assignment with a projective-history distance formalism whose Fubini–Study limit yields exact Born-weight recovery. Fourth, the gauge sector is reformulated more carefully through closure-consistency constraints, anomaly freedom, chirality, and minimal redundancy, narrowing the admissible low-energy symmetry toward the Standard Model pattern. In DDFT, time is not primitive but emerges as the order of admissible realized presents. Geometry is not assumed but reconstructed from stabilized relational covariance. Gravity appears as the low-defect continuum compression of closure inconsistency, while quantum behavior appears when delayed realization remains non-unique across admissible histories. Gauge connections arise as the minimal structures required to preserve definability content under local representational redundancy. The present paper does not claim a final mathematically closed derivation of every physical sector. Instead, it provides a substantially more formal, explicit, and testable framework than earlier versions, with clearly identified assumptions, bottlenecks, and recovery limits. It also formulates concrete phenomenological windows, including energy-dependent propagation delays, curvature-induced interference asymmetries, black-hole information leakage, and delayed corrections to exact Schrödinger compression. The central thesis of the work is that spacetime, quantum probability, and gauge-consistent physical law can all be understood as different regimes of a single delayed definability principle. In this sense, DDFT is proposed not as a decorative synthesis, but as a more rigorous mother framework beneath relativity, quantum theory, and emergent field structure.

A Single Equation for Physical Realization

Luka Gluvić

This work presents a minimal and unified formulation of physical reality based on a single coupled system of two scalar fields: a phase S(x) and a realization density ρ(x). The dynamics is completely determined by two principles: conservation of a realization current and a geometric constraint linking the norm of the phase gradient to the structure of the density field. Together, these relations form a closed system with no additional dynamical assumptions. From this system, all major physical regimes emerge as limiting cases. When the density is uniform, propagation is null and describes lightlike behavior. When the geometric constraint reduces to a constant, the system reproduces classical Hamilton–Jacobi dynamics for massive particles. When the density varies significantly, the coupled system yields quantum behavior, including the Schrödinger equation in the appropriate limit. In this framework, the wave function is not a fundamental entity but an emergent representation of the underlying geometric structure of realization. Interference arises from phase consistency, and quantum behavior reflects the nontrivial structure of the realization density rather than intrinsic indeterminism. The theory also naturally incorporates gravitation by promoting the spacetime metric to a dynamical field. In the appropriate limit, the stress–energy tensor reduces to that of classical matter, and Einstein’s field equations are recovered. Regions where the realization density approaches zero define a geometric boundary where timelike realization ceases, corresponding to horizon-like structures. The central result is that a single coupled equation governs propagation, mass, quantum behavior, and gravitational structure. Physical reality is determined by global consistency of realization rather than by selection among multiple possibilities. This formulation provides a minimal geometric unification of light, matter, quantum phenomena, and gravity within a single coherent framework.

Coherent Projection Dynamics A Pre-Geometric Reconstruction Framework for Quantum Theory, Entanglement, Gauge Structure, Spacetime, Gravitation, and Physical Constants

Borros Arneth

We develop a pre-geometric reconstruction framework in which quantum mechanics, entanglement structure, gauge symmetry, locality, Lorentzian spacetime geometry, gravitation, and physical constants emerge from recursively stabilized coherent Hilbert-relational organization. The framework begins from a primitive coherent substrate consisting of compositional accessibility relations and complex transport amplitudes. No background spacetime manifold, metric geometry, or particle ontology is assumed fundamentally. The central proposal is that coherent Hilbert structure is more fundamental than spacetime geometry. Observable spacetime emerges through projection stabilization: a physical stability-selection mechanism dynamically selecting recursively stable coherent sectors from deeper relational structure. Quantum mechanics emerges from norm-preserving coherent transport. Entanglement emerges from nonfactorizable relational closure. Gauge symmetry emerges as redundancy of coherent transport representation. Classicality emerges through decoherence and stability selection. Lorentzian geometry emerges statistically from projected accessibility organization. Gravitation emerges thermodynamically as equilibrium relaxation of projected geometry. The framework is presented not as a completed unified theory, but as a reconstruction program aimed at explaining why physical reality organizes itself through Hilbert structure, gauge redundancy, locality, spacetime geometry, and thermodynamic gravitational dynamics.

Pre-Einsteinian Coherent Relational Dynamics A Pre-Geometric Framework for the Emergence of Quantum Theory, Gauge Structure, Probability, Matter, Spacetime, Gravitation, and Physical Constants from Stability-Selected Transport Organization

Borros Arneth

We develop a pregeometric reconstruction framework in which quantum mechanics, gauge symmetry, probabilistic structure, matter, Lorentzian spacetime geometry, gravitation, and physical constants emerge from recursively stabilized coherent relational transport organization. The framework begins from a primitive causal-relational substrate consisting only of fluctuating accessibility relations and compositional transport structure. No background spacetime manifold, metric geometry, particle ontology, or external temporal parameter is assumed fundamentally. The theory further proposes that the preconditions underlying Einsteinian physics must already exist at the pre-geometric level as deeper relational consistency principles. Lorentz invariance, causal structure, covariance, conservation laws, and gravitational equivalence are interpreted as emergent macroscopic expressions of more primitive coherent accessibility constraints. A generalized spectral transport operator governs coherent relational evolution and generates stable eigensectors corresponding to persistent physical structure. Quantum mechanics emerges from coherent compositional consistency and norm-preserving recursive transport flow. Gauge symmetry emerges as local redundancy of coherent transport representation. Classical mechanics emerges through stationary coherent transport stabilization. A reconstruction of the Born rule is proposed in which quadratic probability amplitudes arise from multiplicative persistence consistency under independent coherent composition. Lorentzian spacetime geometry emerges statistically from stabilized causal accessibility organization, while gravitation emerges thermodynamically as equilibrium relaxation of coherent accessibility geometry. The framework further proposes that physical constants correspond to frozen stability invariants selected during primordial coherent transport evolution. In particular, the fine-structure constant is interpreted as a stable surviving coherent phase-accessibility ratio associated with recursive phase closure. The theory therefore attempts not merely to reproduce known equations, but to explain why physical reality universally organizes itself through Hilbert structure, gauge redundancy, localization, Lorentzian geometry, and thermodynamic gravitational dynamics. In particular, the framework proposes that Einsteinian spacetime physics emerges from deeper pre-Einsteinian coherent relational conditions governing recursive transport accessibility before spacetime itself exists.

Material Extension and Relational Separation Without Fundamental Spacetime

Peter Erik Ronald van Heijst

Modern theoretical physics rests on two highly successful but conceptually distinct frameworks: quantum mechanics and general relativity. While both theories are experimentally confirmed to high precision within their respective domains, they rely on fundamentally different starting points. General relativity takes spacetime as a primitive geometric structure, whereas quantum mechanics is formulated in terms of abstract state spaces without intrinsic spacetime meaning. Most approaches to quantum gravity attempt to reconcile this tension by modifying, quantizing, or discretizing spacetime itself. Even in approaches where spacetime is said to be “emergent,” it typically remains the primary conceptual backdrop on which physical processes are defined. Despite extensive efforts, there is no consensus on whether spacetime should be regarded as fundamental or derivative. In this work, a more radical starting point is explored. Rather than modifying spacetime or its geometry, we ask whether spacetime can be excluded entirely from the fundamental layer of the theory and recovered only at a later, operational stage. The central question is not how spacetime behaves, but whether the notion of “what lies between physical objects” must be spatial or temporal at the most fundamental level. We propose a framework—referred to here as Super Relativity (SR)—based on a single pre-geometric postulate: the existence of a monotonically expanding set of possible quantum configurations, referred to as the flux. Formally, this flux is represented as a monotone, σ-finite family of capacity measures on a common configuration space (introduced in Section 2). This postulate deliberately refrains from assuming spacetime, time ordering, metric structure, causality, or dynamics. Within this pre-geometric core, two derived, dimensionless notions are introduced: utilization, describing the realization of configurations, and saturation, defined as the ratio between utilized and available configurations. A central structural element of SR is the strict separation between a core layer and an interface layer. In the core layer, all quantities are pre-geometric and dimensionless, and no reference is made to space, time, motion, energy, or interaction. Only at the interface layer are operational notions introduced, including clocks, rulers, and signal propagation. Spacetime, in this construction, is not a dynamical entity but an effective bookkeeping structure that encodes relative rates of change once a calibration to physical units is performed. Within this framework, gravitational phenomena do not originate from spacetime curvature taken as fundamental. Instead, they arise from variations in saturation that, at the interface level, manifest as uniform rescalings of physical processes. When expressed in geometric language, these rescalings reproduce the standard predictions of general relativity, including gravitational time dilation and the equivalence between gravitation and acceleration. The invariant local speed of light is not postulated but follows as a derived consequence, since both clock rates and signal propagation are affected identically by the same underlying saturation mechanism. The aim of this paper is not to introduce new empirical predictions beyond those of general relativity, nor to present a complete theory of quantum gravity. Rather, the objective is foundational: to demonstrate that the mathematical structure of general relativity can be reconstructed from a single pre-geometric postulate without assuming spacetime as part of the fundamental ontology. In this sense, SR should be understood as a reconstruction and reinterpretation of known physics, rather than as a competing dynamical theory. An extended and fully explicit formulation of the framework, including all intermediate steps, is available in a companion preprint (version V12) deposited on Zenodo. The present paper restricts itself to the minimal conceptual and mathematical structure required to establish logical consistency and to demonstrate the emergence of general-relativistic behavior at the interface level.

A Probabilistic–Geometric Unification of Relativistic and Quantum Dynamics Information Curvature as a Common Structural Equation

Ryusho Nemoto

The absence of a common mathematical structure underlying quantum theory and relativistic physics remains a central obstacle to unification. While relativity is formulated in terms of spacetime geometry and covariance, quantum theory is intrinsically probabilistic, relying on amplitudes, uncertainty, and statistical interpretation. Existing unification programs typically attempt to quantize geometry or to geometrize quantum fields, but the probabilistic structure itself is rarely treated as a fundamental geometric object. In this paper, we propose a unified description of relativistic and quantum dynamics based on probabilistic geometry. Probability densities are taken as primary variables and are endowed with an intrinsic information–geometric structure defined by the Fisher–Rao metric. Within this framework, physical motion is described as the covariant evolution of probability distributions on a statistical manifold rather than as trajectories in a preassigned phase space or Hilbert space. The central result is a unified probabilistic–geometric field equation in which the relativistic d’Alembertian acting on the probability density is coupled to the scalar curvature of the associated information manifold. In an appropriate nonrelativistic limit, this equation reproduces the quantum potential as a curvature term, establishing a direct correspondence between quantum effects and informational geometry. Relativistic covariance is preserved throughout, allowing quantum and relativistic structures to appear as different regimes of a single probabilistic equation. The proposed framework does not introduce new particles, interactions, or quantization postulates. Instead, it provides a structural unification in which quantum and relativistic features emerge from the geometry of probability itself.
