Fermionic Universe Hypothesis: The Unified Nature of Dark Components

Introduction The Fermionic Universe Hypothesis (FUH) proposes a unified origin for dark components: dark matter, dark energy, and black hole‑like objects arise as different phases of a single fermionic field ψ (keV‑scale mass). Instead of treating dark matter and dark energy as separate entities (as in ΛCDM), FUH links them to the thermodynamics of a ψ condensate: dark matter = degenerate Fermi gas of ψ; dark energy = low‑density phase with w≈−1; black holes = ultra‑dense condensate defects (no singularities). FUH yields testable predictions for EHT, LISA, Euclid, and particle experiments, offering a physically grounded alternative to the standard cosmological model.
