Abstract This article does not claim to present a successful theory of quantum gravity. Instead, it undertakes a systematic and self-aware survey of the research program aiming to derive both quantum mechanics and general relativity from a purely relational network, based on a set of minimal ontological postulates. The framework rests on three axioms: (1) physical reality consists of nodes without intrinsic properties and their symmetric relations; (2) the relation strengths are non-negative and symmetric, with the total information capacity conserved as an ensemble expectation; (3) local evolution is restricted to redistribution of relations within triads. We honestly display and rigorously distinguish the conceptual achievements from the essential obstacles of this framework. On the quantum side, we obtain solid conceptual progress: the Born rule, unitary evolution, and topological nonlocality of entanglement all emerge naturally as representation-theoretic consequences of the statistical description of a finite information capacity network. This strongly suggests that the mathematical structure of quantum mechanics may be a generic feature of the statistical representation of any complex informational system satisfying “finite information + local relational evolution.” On the gravitational side, however, we encounter chasms that current mathematical and conceptual tools cannot bridge. A central contribution of this article is to clearly label these obstacles as fundamental open scientific problems: the conflict between a positive-definite relational ontology and the target of pseudo-Riemannian signature (signature problem); the missing coarse-graining procedure from a discrete network to a smooth manifold (coarse-graining problem); and the disharmony between external algorithmic time and emergent physical time (time problem). We argue that these are not technical details unique to this framework, but core challenges that any “spacetime from relations” program must confront. The article positions itself as a “conceptual cartography”—it precisely delineates the known boundaries of this research program, exposes the fatal rift often bypassed in mainstream discourse, and transforms all unresolved issues into a formal invitation for future investigation.

This paper proposes a theoretical framework—Relational Theory—based on dynamic relational networks, in which discrete spacetime serves as the fundamental ontology, while continuous geometry and gravity emerge as macroscopic statistical phenomena. This framework unifies the description of matter, spacetime, and gravity, aiming to bridge the theoretical divide between quantum field theory and general relativity, while providing a discrete spacetime physical substrate for the orthodox prob abilistic interpretation of quantum mechanics. The fundamental ontology of the universe is defined as the evolution of a dynamic relational network, where nodes represent fundamental quantum units of space, edges correspond to adjacency relations between units, and matter manifests as complex probability amplitude excitation modes propagating on the network. The framework is built upon two foundational axioms: the matter field undergoes unitary evolution driven by the graph Lapla cian operator, and the network topology dynamically reconfigures in response to the matter energy density, with links undergoing continuous generation and decay, while matter evolution exhibits the discrete alternating character of “annihilation here, creation there.”Under the mean-field continuum limit, the two axioms respectively evolve into a Schr¨odinger equation describing matter propagation in curved space and a link density equation characterizing the response of spacetime geometry to matter distribution. These two sets of equations form a self-consistent feedback mechanism in which matter and spacetime geometry mutually constrain each other. The study demonstrates that grav ity is not a fundamental interaction, but rather a statistical emergent entropic force driven by the inhomogeneous spatial distribution of network link density.This paper further proposes a dynamic relational network interpretation, circumventing the collapse paradox of the Copenhagen interpreta tion, the universe-splitting problem of the many-worlds interpretation, and the non-locality dilemma of hidden variable theories. It provides an underlying topological explanation for wave function evo lution, the measurement problem, and the origin of quantum probability. The laws of black hole thermodynamics and the fundamentals of the holographic principle can all be reasonably explained within this microscopic topological framework. The paper systematically verifies the mathematical self-consistency of the model, distinguishes rigorously derived conclusions from conjectures awaiting verification, and demonstrates the feasible pathways for numerical simulation tests and astronomical observational corroboration.
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.
General relativity (GR) and quantum mechanics (QM) resist unification not because one is wrong but because each is a coarse-graining of the same thing, and the two projections discard complementary information. This note makes that claim precise inside Event Density (ED), a framework in which spacetime and its fields are not fundamental but emerge from a discrete, relational substrate — a network of events, their participation, and their commitment - governed by thirteen primitives, one of which is an irreversible arrow of time. We show that both GR and QM are time-symmetric, so each has already coarse-grained the arrow out; what each retains is a different reversible residue of the substrate’s time, the local rate in GR and the global phase in QM. Because both are projections of one arrow, they are not unified by building a bridge between them but by recovering their common source. Concretely, ED identifies the object QM needs as its pointer-basis selector with the object GR needs as its preferred time: they are one primitive doing two jobs, and the standard “problem of time” therefore does not arise. We are explicit about tier: the QM side is a grounded reconstruction with a stated open residual, the weak-field GR side is derived, but the unification itself is an identification at account tier - distinctive, structural, and as yet carrying no falsifiable prediction of its own.
This paper aims to provide a systematic meta-theoretical framework for the”Quantum Geometrization” research program. From an epistemological perspective, it clarifies that establishing ”information” as the first principle of physics isnot an arbitrary metaphysical presupposition, but is based on two operationallymeaningful meta-rules: conservation of information distinguishability and finitestep computability of physical processes. This paper argues that these two metarules constitute the boundary conditions that any cognizable and testable physicaltheory must satisfy, and together they define the ”operational window of physicalcognition”. Within this framework, spacetime geometry is interpreted as an emergent phenomenon of information structure in the coarse-graining limit, quantumuncertainty is reinterpreted as an inevitable trade-off between levels of information description, and a series of cosmological parameters are traced back to rigidconstraints of information algebra. This paper further synthesizes the core achievements of the Quantum Geometrization series into a unified ”information dynamics”prediction network, and discusses the framework’s scope of applicability, challenges,and future directions. This study provides an epistemological foundation for thecore proposition ”spacetime emerges from information” and places the QuantumGeometrization program within a falsifiable scientific paradigm.
Does Physical Existence Require Predefined Identity, Position, or Distance? This paper investigates a foundational possibility: physical entities may exist without possessing fully defined relational identities, positions, or measurable distances. It proposes that these properties become physically meaningful through relational structures capable of representing the information that defines them. The framework explores two applications of this principle. In quantum physics, it examines the indistinguishability of identical particles, fermionic antisymmetry, bosonic occupation multiplicity, and entanglement through the distinction between physical existence and relational identity. In emergent geometry, it proposes that spatial distinction can precede measurable distance, with metric structure arising from a larger network of physical relations. The mathematical development introduces a weighted relational network and employs graph Laplacians, Green functions, spectral dimension, and effective resistance to investigate the emergence of geometric structure. A relational compensation principle motivates preliminary equilibrium conditions and dynamical models. An initial numerical experiment shows that a localized perturbation can produce a nonlocal structural response across the network. Although this result does not yet reproduce a gravitational law, it provides a concrete starting point for investigating field-like behavior within the proposed framework. The central contribution is a common relational foundation for quantum identity and emergent spacetime geometry, supported by mathematical constructions and preliminary numerical investigation. The work does not claim a completed unification of quantum mechanics and general relativity. Open challenges include deriving a unique network dynamics, three-dimensional space, the Born rule, and gravitational field equations. The principal research question is whether a single relational dynamics can yield quantitative, testable predictions in both quantum physics and emergent spacetime geometry.
In this thesis, we lay out the goal, and a broad outline, for a program that takes quantum mechanics in its minimal form to be the fundamental ontology of the universe. Everything else, including features like space-time, matter and gravity associated with classical reality, are emergent from these minimal quantum elements. We argue that the Hilbert space of quantum gravity is locally finite-dimensional, in sharp contrast to that of conventional field theory, which could have observable consequences for gravity. We also treat time and space on an equal footing in Hilbert space in a reparametrization invariant setting and show how symmetry transformations, both global and local, can be treated as unitary basis changes. Motivated by the finite-dimensional context, we use Generalized Pauli Operators as finite-dimensional conjugate variables and define a purely Hilbert space notion of locality based on the spread induced by conjugate operators which we call "Operator Collimation." We study deviations in the spectrum of physical theories, particularly the quantum harmonic oscillator, induced by finite-dimensional effects, and show that by including a black hole-based bound in a lattice field theory, the quantum contribution to the vacuum energy can be suppressed by multiple orders of magnitude. We then show how one can recover subsystem structure in Hilbert space which exhibits emergent quasi-classical dynamics. We explicitly connect classical features (such as pointer states of the system being relatively robust to entanglement production under environmental monitoring and the existence of approximately classical trajectories) with features of the Hamiltonian. We develop an in-principle algorithm based on extremization of an entropic quantity that can sift through different factorizations of Hilbert space to pick out the one with manifest classical dynamics. This discussion is then extended to include direct sum decompositions and their compatibility with Hamiltonian evolution. Following this, we study quantum coarse-graining and state-reduction maps in a broad context. In addition to developing a first-principle quantum coarse-graining algorithm based on principle component analysis, we construct more general state-reduction maps specified by a restricted set of observables which do not span the full algebra (as could be the case of limited access in a laboratory or in various situations in quantum gravity). We also present a general, not inherently numeric, algorithm for finding irreducible representations of matrix algebras. Throughout the thesis, we discuss implications of our work in the broader goal of understanding quantum gravity from minimal elements in quantum mechanics.
