Paper CCXIX: v2: Dynamic Dark Energy (corrected) Paper CCXIX — Dynamic Dark Energy from Sump Relaxation: Tcosmo = f 2/3

Authors/Creators

  • 1. University of Minnesota

Description

The cosmological constant is resolved by sump relaxation: brane ZPE started at ΛPlanck and is exponentially opposed by the growing sump. The relaxation timescale is Tcosmo = f2/3 bulk/H0 = 1.61 Gyr (≈H−1 0 /9). This generates dynamical dark energy with w(z) crossing −1 at zcross ≈0.4, matching DESI DR1. v2 correction: original formula Tcosmo = r0/c for σ = 500 km/s gives 253 Gyr (wrong). Correct formula uses the G2-derived f2/3 bulk relaxation fraction.

Part of the One-Octonion Brane-Bulk Framework series. Anchor DOI: 10.5281/zenodo.19120873. Community: one-octonion-brane-bulk. Author: Bharathi Dasan Jagadeesan, M.D., University of Minnesota. ORCID: 0000-0002-1143-941X.

Notes

Added a supersession/clarification note (page 1) aligning the dark-energy model with Paper CCLXXXIV (DOI 10.5281/zenodo.20577943): decaying rhoL ~ e^-t/Tsump, thawing quintessence w>-1 (no phantom crossing), w0=-0.9266, DESI DR2 chi2=12.16. Body unchanged.
