Entropyics 11 : Event Horizon–Based Entropy Estimation and Rotational Normalization as ΛCDM Complements (v3)

The full manuscript is available in the “Files” section above. ✔️ This paper presents Entropyics 11, which complements the ΛCDM cosmological model by framing black holes as entropy reservoirs. The cumulative entropy is estimated via event horizon area (Bekenstein–Hawking framework), and its growth rate is compared to cosmic expansion. ✔️ In addition, a rotational normalization index (En = M × ω) is introduced as a simplified proxy for entropy accumulation, enabling comparisons between mass–spin dynamics and curvature recovery. ✔️ Regression analysis across major datasets (SNe Ia, BAO, CMB) shows R² = 0.969 for ΛCDM, 0.999 for the event horizon model, and 0.998 for the normalization index model. In the accelerated regime (z ≤ 0.1), ΛCDM consistency collapses (R² ≈ -124.7), while entropy-based models remain comparatively stable (≈ -4.1 and -3.9). ✔️ These results suggest that entropy accumulation rates—whether measured via horizon area or rotational indices—can supplement ΛCDM by explaining specific phases of expansion. Rather than replacing the standard model, Entropyics offers a quantitative complement that reframes curvature dynamics through information storage.
