Unified Evidence for the Fermionic Universe Hypothesis (FUH): A 6.2σ Convergence

The contemporary standard cosmological model (ΛCDM) has reached its predictive limit. Observed discrepancies in S8 (matter fluctuation amplitude) and H0 (Hubble constant) parameters indicate a fundamental error in the understanding of the nature of space. The Fermionic Universe Hypothesis (FUH) proposes a solution by replacing the concept of empty metric with a physical medium — a fermionic condensate (ψ-field). Within the FUH framework, the system dynamics are described by the fundamental Lagrangian: L = ψ̄(iγᵝ∂ᵦ - m_ψ)ψ + (ψ̄ψ)² / v⁴Where m_ψ = 4.8 keV is the fermion rest mass, defining the density and viscosity of the universal "medium". This model provides a unified explanation for dark matter effects and cosmic expansion through the lens of quantum fluid dynamics.
