Universal Fractal Collapse Constant ∂ ≈ 0.921 ∂≈0.921: Evidence Across Physical Phenomena

We propose that the magnitude of dimensional collapse, defined as ∂=3−df\partial = 3 - d_f∂=3−df, where dfd_fdf is the effective fractal spatial dimension, exhibits a universal behavior across a wide range of physical systems. Through analysis of gas diffusion, cosmic microwave background (CMB) anisotropies, superconductivity, large-scale structure (LSS), and black hole simulations, we consistently observe ∂≈0.921±0.01\partial \approx 0.921 \pm 0.01∂≈0.921±0.01. This suggests the existence of a universal fractal collapse constant underlying emergent geometry in nature and supports the Unified Fractal-Stochastic Model (MFSU).
