Fractal Cosmology and Particle Stability: A Unified Field Perspective in UFQFT

The concept of fractal dimensionality offers a novel perspective for understanding the evolution of the Universe from its pre-Big Bang state to the present epoch. Within the framework of the Unified Fractal Quantum Field Theory (UFQFT), physical structures—ranging from nuclear systems with magic numbers ( D f ≈ 1.4 ) to the large-scale Universe ( D f ≈ 2.7)—can be described as resonance configurations embedded in a fractal spacetime. We propose that the early Universe, prior to the Big Bang, exhibited a higher effective fractal dimension ( D f ≈ 3–4), reflecting a pre-geometric state of symmetry and homogeneity. The subsequent cosmic evolution can then be understood as a dimensional reduction process, wherein fractal dimensionality decreases as structure formation, particle stability, and entropy growth emerge. This approach provides a unified interpretation of particle confinement, nuclear stability, and cosmological expansion, linking microphysical phenomena to cosmic-scale dynamics. The results suggest that fractal dimensionality is not static but evolves as a fundamental parameter of nature, offering new insights into the origin of matter, the dynamics of the Big Bang, and the present large-scale geometry of the Universe.
