1 Introduction

Unifying gravity with quantum mechanics remains a cornerstone challenge in theoretical physics. General relativity (GR) describes gravity as spacetime curvature induced by the energy-momentum tensor (), while the Standard Model unifies electromagnetic, weak, and strong interactions under gauge symmetry (; ; ). Grand Unified Theories (GUTs) like SU(5) face empirical hurdles, including proton decay constraints (; ; ; ) and the hierarchy problem (; ).

Information theory offers a transformative perspective. The holographic principle suggests gravitational physics is encoded on lower-dimensional boundaries (; ; ), entropic gravity posits gravity as an emergent force from information displacement (), and quantum entanglement underpins spacetime emergence (; ). Wheeler’s “it from bit” hypothesis () and the Information Discrimination Theory () propose information as a fundamental substrate, with the latter providing a systematic framework for information dynamics across scales from quantum to cosmological.

This paper focuses on gravitational interactions mediated by a classical information density field, addressing three key objectives:

  • 1. Theoretical Foundation: Establish a rigorous, observer-independent information field with clear physical derivation from classical matter configurations.

  • 2. Mathematical Consistency: Ensure dimensional consistency, gauge invariance, and thermodynamically motivated coupling parameters.

  • 3. Empirical Validation: Provide concrete experimental predictions with detailed feasibility analysis, systematic error control (Figure 1), and differentiation from alternative theories.

2 Theoretical framework

2.1 Information density field construction

Definition 1(Information Density Field). The information density field , with units , quantifies the local Shannon entropy density of classical matter field configurations (Equation 1):where is the probability of microstate (e.g., a specific density bin) within a coarse-graining volume , corresponding to the nuclear interaction length scale ().

The coarse-graining scale

m is chosen to capture the complexity of hadronic interactions, where strong force dynamics dominate matter field configurations. This scale ensures:

  • Physical Relevance: It reflects the characteristic length where nuclear interactions govern field statistics, avoiding sub-nucleon quantum fluctuations.

  • Classical Validity: The field remains classical, with probabilities derived from statistical mechanics, suitable for macroscopic gravitational effects.

  • Computational Tractability: Finite state spaces enable practical calculations of entropy density.

The probabilities are constructed from invariant physical quantities, such as local energy density, particle number density, and field gradients, ensuring observer independence.

Proposition 1(Observer Independence). The information density field is observer-independent when probabilities are derived from coordinate-invariant scalars.Proof The information density field achieves observer independence through its construction from coordinate-invariant scalar quantities. Consider a coordinate transformation . The probabilities are defined via a Gibbs distribution (Equations 2, 3):where is the matter density field, is the equation of state, accounts for gradient contributions, and is the partition function.Crucially, represents the energy density functional of field configuration , built from coordinate-invariant scalars. Under Lorentz transformations, the energy density transforms as the temporal component of the energy-momentum tensor , but the relative probabilities remain invariant because they depend only on energy differences , which are frame-independent for configurations at the same spacetime point. The invariant construction ensures that the Shannon entropy and hence remain observer-independent scalars ().Note that: while the absolute temperature (and thus ) may vary with the observer due to relativistic effects (e.g., time dilation or frame-dependent energy measurements), the energy differences are defined relative to the local rest frame of the matter configuration, ensuring they are boost-invariant scalars. This construction avoids dependence on global observer frames and aligns with relativistic thermodynamics, where effective temperatures are frame-dependent but derived invariants (such as entropy densities) remain consistent across observers.As illustrated in Figure 2 the information density peaks near compact objects due to complex nuclear field configurations. This figure shows the radial profile of information density around a neutron star, computed using nuclear thermodynamic parameters and demonstrating the characteristic enhancement near the stellar surface where nuclear interactions dominate the entropy production. The field satisfies a normalization condition (Equation 4):over a spacelike hypersurface , where is the determinant of the induced 3-metric and is the total information content in bits ().

FIGURE 2

), with the neutron star radius indicated by the blue shaded region. The sharp peak reflects the complex nuclear interactions that dominate information content near the stellar surface.

Definition 2(Shannon Entropy Field). The dimensionless Shannon entropy field is given by Equation 5:where .

2.2 Thermodynamically motivated action principle

The covariant action integrates gravitational, information, matter, and gauge field dynamics, motivated by thermodynamic principles linking information to entropy (

;

Jacobson, 1995

):

where the individual Lagrangian terms are defined by

Equations 7

11

:

with:

  • : Ricci scalar , : gravitational constant , : speed of light ().

  • : information density , .

  • : scalar test field (), : mass ().

  • : information gauge field strength, : information current, : gauge field ().

The coupling constants are derived from nuclear thermodynamics (Equations 1214), reflecting the entropy-energy equivalence at hadronic scales ():

Definition 3(Thermodynamic Coupling Constants).where is Boltzmann’s constant, K, and m.The constant governs information propagation, controls self-interaction, and mediates matter-information coupling, all scaled by nuclear thermodynamic parameters to ensure weak, perturbative effects consistent with observed gravitational phenomena (Jacobson, 1995).Physical Significance: These coupling constants represent the fundamental strength of information-gravity interactions. The thermodynamic derivation ensures that information effects remain perturbative corrections to Einstein gravity, consistent with experimental bounds while producing measurable signatures in precision experiments. The nuclear scale m provides the natural cutoff where information dynamics become relevant to gravitational physics.

2.3 Field equations and conservation laws

Variation of the action yields the coupled field equations, describing the interplay of gravity, information, matter, and gauge fields.

Theorem 1

(Modified Einstein Equations). The gravitational field equations are:where the stress-energy tensors are given by Equations 1618:

Theorem 2

(Information Field Dynamics). The information field evolves according to:where .

Physical Interpretation: This equation describes how information density evolves under self-interaction ( term) and matter coupling ( term), with the logarithmic potential ensuring thermodynamic consistency with entropy principles. The source term represents information creation through matter field fluctuations.

Theorem 3

(Matter Field Coupling). The scalar matter field satisfies:

Theorem 4

(Gauge Field Dynamics). The information gauge field evolves as:where .

Physical Interpretation: This standard gauge field equation describes how the information gauge field responds to the information current , ensuring local gauge invariance while coupling to information density gradients. The current includes both convective and diffusive contributions, representing information transport and spread respectively.

The information current satisfies a continuity equation reflecting dynamic interactions (Equation 22):Physical Interpretation: This equation describes the creation and destruction of information through matter coupling ( term) and self-interaction ( term). The non-conservation indicates that information can be generated by matter field fluctuations or dissipated through internal interactions, consistent with thermodynamic principles. The Bekenstein bound is enforced dynamically (Equation 23):via boundary conditions in Equation 19 ().

2.4 Information gauge symmetry

Definition 4(Information Gauge Transformation). The theory is invariant under transformations (Equations 24, 25):where are gauge functions.

Theorem 5

(Gauge Invariant Action). The gauge action (Equation 26) is invariant under the transformations in Equations 24, 25, ensuring gauge symmetry ().

2.5 Theoretical framework context

The theoretical framework presented here builds upon the foundations of information-theoretic approaches to gravity while maintaining focus on gravitational interactions as a crucial first step toward broader unification. The computational framework is designed to accommodate future extensions to a more comprehensive gauge structure when theoretical development progresses beyond the current gravitational focus.

The coupling constants (, , ) represent the foundational parameters of what will eventually become a more comprehensive theoretical structure. This strategic approach ensures theoretical consistency while maintaining experimental testability at each development stage, allowing for systematic validation of the information-theoretic approach to fundamental interactions.

3 Phenomenological predictions

The framework predicts observable gravitational effects driven by information density gradients, distinguishable from alternative theories such as modified gravity (; ), dark matter substructure (), and instrumental artifacts (; ).

3.1 Modified gravitational lensing

Information density near massive objects modifies light deflection by contributing to spacetime curvature.

Theorem 6

(Information-Modified Lensing). For a point mass with information density profile, the deflection angle is given by Equation 27:where the information correction is defined by Equation 28:for neutron stars with average density kg and average information density bit , derived from nuclear entropy calculations ().

Physical Interpretation: The correction represents a fundamental modification to spacetime curvature driven by information content, distinguishable from mass-energy effects through its dependence on entropy density rather than rest mass. This provides a unique observational signature of information-theoretic gravity (Figure 3).

FIGURE 3

The correction arises from the information stress-energy tensor (Equation 16), which perturbs the Schwarzschild metric. For a neutron star ( kg, radius km), the information density peaks at bit due to complex nuclear interactions, yielding a detectable lensing deviation ().

3.2 Quantum phase shifts in matter interferometry

The information field induces phase shifts in matter waves propagating through regions of varying information density, detectable in interferometric experiments (Figure 4).

FIGURE 4

Theorem 7

(Information-Induced Phase Shifts). A matter wave accumulates a phase shift described by Equation 29:where is the Shannon entropy field, and is an entropy-gradient coupling constant. For a laboratory baseline of m, with bit and eV, the phase shift estimate (Equation 30) gives:

Physical Interpretation: This phase shift arises from the information-dependent potential term in the matter field equation, analogous to the Aharonov-Bohm effect but driven by information gradients rather than electromagnetic fields. The entropy term contributes negligibly in laboratory settings but provides theoretical completeness.

Recent work on entropy-based gravity models in quantum metrology contexts () provides complementary insights into information-geometry relationships, particularly for isotropic and anisotropic spacetimes, further supporting the theoretical foundations of information-theoretic approaches to gravity.

4 Experimental validation strategy

The experimental strategy prioritizes high-feasibility, high-impact tests to validate the predicted gravitational effects, with a focus on distinguishing information-theoretic signatures from alternative explanations. The roadmap spans near-term (1–2 years), medium-term (2–4 years), and long-term (3–5 years) efforts, leveraging existing and emerging technologies.

4.1 Priority framework and timeline

4.2 Systematic error analysis and mitigation

To achieve the required precision, systematic errors must be rigorously controlled. The error budget quantifies contributions from statistical and systematic sources, with mitigation strategies tailored to each experiment.

Definition 5(Systematic Error Budget). The total systematic uncertainty is given by Equation 31:where each term represents the variance of a specific error source.

4.3 Alternative theory discrimination

To ensure the predicted effects are uniquely attributable to information-theoretic gravity, we differentiate them from competing models:

Theorem 8

(Discriminating Signatures). Information-theoretic effects exhibit distinct signatures:

  • 1. Versus Modified Gravity: Corrections scale with , not curvature terms like or models ().

  • 2. Versus Dark Matter: Effects correlate with baryonic information content, independent of non-baryonic mass distributions ().

  • 3. Versus Instrumental Artifacts: Signatures show specific spatial and temporal correlations with information density gradients, unlike random or systematic instrumental noise ().

Experimental protocols include control measurements in low-information-density regions to isolate instrumental effects and cross-correlation with baryonic matter distributions to rule out dark matter contributions ().

8 Conclusion

This paper presents a rigorously formulated theoretical framework for gravitational interactions mediated by a classical information density field. The approach provides a novel perspective on gravity through information dynamics while maintaining focus on empirically testable predictions. Key achievements include:

  • 1. Robust Theoretical Foundation: The information field is derived from nuclear-scale classical matter configurations, ensuring observer independence through invariant statistical mechanics (; ). Thermodynamic principles motivate coupling constants, linking information to gravity via entropy-energy equivalence (; Jacobson, 1995).

  • 2. Mathematical Consistency: The framework achieves dimensional consistency, complete gauge invariance (including novel information gauge symmetries), and dynamic enforcement of conservation laws, validated through analytical proofs and numerical simulations (; ).

  • 3. Experimental Testability: Two precise predictions—gravitational lensing corrections and quantum phase shifts ( rad)—are within reach of current technologies, supported by detailed error budgets and discrimination protocols (; ; ; ).

  • 4. Comprehensive Verification: Python code verifies theoretical consistency and experimental predictions, with Monte Carlo simulations quantifying uncertainties, ensuring reproducibility.

The framework addresses the physical basis of the information field, motivating coupling parameters, and enhancing experimental feasibility. The current framework focuses specifically on gravitational interactions, providing a foundation for potential future theoretical extensions. The high testability at macroscopic scales distinguishes it from Planck-scale theories, offering a practical avenue to probe information’s role in gravity (; ).

Broader implications extend to fundamental physics, suggesting information as a dynamical substrate underlying spacetime and gravity (; ). If validated, this approach could provide new insights into the relationship between information, entropy, and gravitational phenomena, potentially bridging classical relativity with quantum information theory and opening new avenues for theoretical and experimental physics research. Even null results would provide valuable constraints on information’s role in gravitational interactions, advancing our understanding of the fundamental nature of spacetime and gravity.
