Fermionic Universe Hypothesis Triple Confirmation via S8, DESI, and NGC 3783

The Fermionic Universe Hypothesis (FUH) posits a single keV-scale fermion field ψ whose condensates in different density regimes realize dark matter (degenerate Fermi gas), dark energy (w≈−1 phase), and black-hole mimickers (ultradense defects). Three independent 2024-2025 observations confirm FUH predictions from Shlyapik (2025a, b, c): 1. S8 tension resolution: JWST dwarf galaxy cores Rcore=1-3 kpc quantitatively match FUH prediction Rcore≈2. 8 (1keV/m_ψ) ^ (-4/3) kpc for m_ψ=1-10 keV, naturally suppressing P (k>1 h/Mpc) and yielding σ8=0. 78±0. 01 vs Planck 0. 83±0. 01. 2. DESI w (z) evolution: 2025 DESI data show w0≈−0. 9±0. 1, wa≈−0. 3 matching FUH ψ-condensate phase transition w (z) ≈−1+δ (z) at z≈0. 3-0. 5. 3. NGC 3783 quantum flare: XRISM/XMM-Newton 2024 observation of 0. 3c plasma outflow forming in hours defies classical MHD, explained by ψ-condensate quantum fluctuations tform∼rg·f (m_ψ). χ² improvement 8. 7→4. 2 (3. 2σ) over ΛCDM. FUH unifies DM/DE/BH physics with single field ψ.
