Fractal Holographic Unified Spacetime Theory (FHUST): A Multiscale Framework for Quantum Gravity and Spacetime Evolution

This paper introduces an integrative Fractal Holographic Uni?fied Spacetime Theory (FHUST), which combines dynamic frac?tal networks with the Fractal Holographic Emergent String Theory(FHEST) to construct a multiscale, self-consistent model of quan?tum gravity. Centered on fractal geometry, the theory begins withrigid fractal recursive nesting at the Planck scale, utilizes dynamicfractal shortcut networks to explain quantum entanglement and su?perluminal correlations, and incorporates holographic principles withfractal Calabi-Yau manifolds to unify the evolution of spacetime frommicroscopic quantum fluctuations to macroscopic general relativity.FHUST systematically integrates three categories of fractal models,proposing modified Einstein field equations, a fractal black hole en?tropy formula, and a geometric mechanism for generating StandardModel particles. The paper also outlines experimental validation path?ways, including gravitational wave dispersion, black hole horizon per?turbations, and fractal excitation state detection.
