I propose a fundamental shift in our understanding of the cosmic vacuum. My research indicates that space is not an empty void but a material medium—a viscous fermionic condensate (the "psi-field"). While classical physics struggles with "dark" mysteries, my Fermionic Universe Hypothesis (FUH) resolves these paradoxes by introducing a single physical reality: a medium with a fundamental mass (mₚsi) of 4. 8 keV and a dynamic viscosity (eta) of 1. 2 * 10^-15 Pa·s.
