Abstract

The unification of general relativity (GR) and quantum mechanics remains one of the most fundamental challenges in theoretical physics. This proposal introduces the Horizon Expansion Fractal (HEF) model, a novel recursive geometric framework integrating space-time dynamics across quantum and cosmological scales. Governed by a self-similar fractal transformation, HEF employs a scaling function dependent on the Hubble parameter, a beta function regulating rotational decay over cosmic time, and an escape radius linked to cosmic expansion. This model suggests testable predictions in cosmic microwave background (CMB) imprints, large-scale structure distributions, and gravitational wave spectra. By linking GR, Loop Quantum Gravity (LQG), and quantum cosmology within a mathematically consistent recursive framework, HEF offers a new paradigm for understanding space-time evolution.

1. Introduction

Reconciling quantum mechanics with general relativity is an unresolved problem in modern physics. General relativity describes space-time as a continuous manifold, whereas LQG suggests a fundamentally discrete nature at the Planck scale. The HEF model proposes a recursive geometric framework wherein space-time undergoes self-similar expansion regulated by cosmic parameters. This section outlines the primary components governing HEF:





A scaling function linked to the Hubble parameter,




A beta function dictating rotational decay over cosmic time,




An escape radius encoding space-time expansion across different scales.



2. Mathematical Foundations of HEF

2.1 Recursive Fractal Geometry in Space-Time

HEF constructs space-time as a recursive transformation of an initial state, defining a hierarchy of structures at increasing scales. The governing transformation equation is: where , , and encode scaling, rotation, and escape parameters, respectively. The recursive formulation extends into three dimensions:

 

This framework aligns naturally with large-scale cosmic structures.

3. HEF and Cosmic Expansion

The standard FLRW cosmology, governed by the Friedmann equations: is mimicked in HEF through recursive scaling: With , the solution follows an exponential expansion consistent with FLRW predictions.

4. HEF vs. Einstein's Field Equations

4.1 HEF as a Fractal Space-Time Model

Comparing to Einstein's equations: HEF reinterprets curvature through recursive self-similar transformations rather than continuous deformation.

5. HEF and Loop Quantum Gravity

HEF's recursive discretization aligns with LQG spin network evolution, suggesting a self-similar coarse-graining of space-time. This correspondence provides a natural link between classical GR and quantum geometry.

6. HEF Field Equations

The modified field equations in HEF take the form: where incorporates fractal contributions. Expansion dynamics modify the standard FLRW equations, providing an alternative mechanism for late-time cosmic acceleration.

7. Implications for Cosmology and Black Holes

HEF alters black hole solutions by introducing recursive fractal perturbations: This suggests quantum-corrected horizons and a resolution to the information paradox.

8. HEF Model Parameter Estimations

Observational constraints from Hubble parameter data provide best-fit values for HEF parameters, demonstrating consistency with supernovae and BAO measurements while reducing dependence on dark energy.

9. Conclusion

The HEF model provides a fractal-based reinterpretation of cosmic expansion and space-time geometry, linking general relativity and quantum gravity within a recursive framework. Its implications extend beyond theoretical cosmology into observational astrophysics and quantum gravity research. HEF offers an alternative explanation for cosmic acceleration, potentially reducing the reliance on dark energy and modifying the interpretation of large-scale structure formation. Additionally, the model introduces a new approach to black hole physics, where recursive transformations contribute to quantum-corrected event horizons and modified entropy relations.

Future research directions include refining HEF’s effective action, exploring its compatibility with holographic principles, and conducting numerical simulations to test its predictions. Observationally, signatures of HEF could appear in cosmic microwave background fluctuations, gravitational wave signals, and deviations in galaxy clustering statistics. If validated, HEF may provide a profound shift in our understanding of space-time and its evolution, offering a unified framework for gravity at both macroscopic and quantum scales.
