The ΛCDM Assumption
ΛCDM inserts vacuum energy Λ tuned to data. QFT prediction overshoots by 10¹²⁰ → the “worst prediction in physics”.
The Dephaze Operator
E²(z) = Ωm0(1+z)³ + (1−Ωm0)[1 + β ln a], a=(1+z)−1
w(a) = −1 − β / (3[1 + β ln a]) (β<0 ⇒ quintessence, stable)
Numerical Validation
Pantheon+ Supernovae
Test χ²/ν: ΛCDM = 1.11 vs. Dephaze = 0.99 (better generalization).
BAO Geometry (BOSS DR12)
Both models fit within 1σ. Dephaze retains predictive power with β.
RSD Growth
ΛCDM overpredicts fσ₈. Dephaze (β<0) softens growth → improved match.
One-Move Checkmate
ΛCDM survives only by re-fitting σ₈. Fix σ₈=0.811 (Planck prior):
ΛCDM collapses (χ²↑).
Dephaze unchanged (β absorbs growth correction).
| Scenario | ΛCDM | Dephaze |
|---|---|---|
| RSD χ² (σ₈ fixed) | Fails | Stable |
| BAO+RSD total | Worse | Better |
Conclusion
Dark energy is not vacuum but the Φ³ log-tension. Dephaze passes SN, BAO, RSD and survives the σ₈ “removal move”. ΛCDM does not.
