The Unified Fractal Quantum Field Theory (UFQFT) proposes a resonance-geometric framework inwhich matter, interactions, spacetime, and cosmology emerge from the dynamics of two fundamentalfields: the energy field (Φ) and the charge field (Ψ), embedded within a fractal spacetime characterizedby a critical effective Hausdorff dimension of D ≈ 2.7. In this paradigm, elementary particles are notfundamental point-like entities but stable resonance configurations of coupled Φ–Ψ fields, while mass,charge, spin, and particle stability arise from fractal resonance structure and dimensional localization.The theory identifies D ≈ 2.7 as a critical threshold at which confinement, long-range interactions,temporal evolution, and stable matter coexist, providing a unified geometric explanation for theemergence of ordinary matter, dark matter, dark energy, and the arrow of time. Gravity is reinterpretedas an emergent symmetry-restoring response of the fractal field, whereas electromagnetic, weak, andstrong interactions arise from distinct resonance modes and topological transitions of the sameunderlying field system. UFQFT further extends naturally to nuclear structure, halo nuclei, neutrinooscillations, CP violation, baryogenesis, black-hole interiors, neutron stars, and bubble cosmology,offering a common geometric origin for phenomena traditionally described by separate theoreticalframeworks. A scale-dependent dimensional flow from microscopic fractal regimes to macroscopicclassical geometry establishes a UV–IR bridge linking particle physics with cosmological structureformation and large-scale dynamics. The framework yields a broad range of experimentally testablepredictions, including fractal corrections to particle lifetimes and scattering processes, modifications toneutrino oscillation patterns, sub-millimeter deviations from Newtonian gravity, distinctive signaturesin halo nuclei, scale-dependent suppression of the cosmological matter power spectrum, non-standardgravitational-wave propagation, and observable imprints in future cosmological surveys and precisionlaboratory experiments. Collectively, UFQFT suggests that the Universe is fundamentally a hierarchyof resonant geometric structures rather than a collection of elementary particles and forces, providing aunified and falsifiable pathway toward the geometric unification of quantum physics, gravitation, andcosmology
