CCC+TL Hybrid Model Tension with Cosmic Chronometer H(z) Data Drops to 0.13 Sigma After Phenomological Correction for Differential Aging

The paper re-examines a prior claim of 6-sigma tension between CCC+TL fits to SN Ia and CC-derived H(z) values. Cosmic chronometer ages rely on stellar population synthesis calibrated exclusively under standard-model physics, so they embed implicit assumptions about constant couplings and photon energy loss that the alternative cosmology violates. Gupta demonstrates that inserting a redshift-dependent correction scaling with the tired-light contribution z_t removes the discrepancy while leaving local stellar calibrations untouched because z_t equals zero at z approximately 0.

This approach directly engages the Hubble tension by testing whether an expanding-universe model with co-varying constants can simultaneously satisfy both distance-ladder and differential-age data once the chronometer pipeline is adjusted for its own model dependence. The correction magnitude is physically motivated by the shorter cooling times expected when electromagnetic coupling strength evolves, a prediction absent from Lambda-CDM chronometer reductions.

No new stellar-evolution calculations are performed; the result is therefore a sensitivity test rather than a definitive validation. Full resolution requires recomputing isochrones and population-synthesis grids inside the CCC+TL parameter space, after which the same CC catalog can be re-derived and refit.

Next steps include cross-checking the corrected H(z) against BAO and CMB-derived distances under identical CCC+TL assumptions, plus targeted JWST observations of quiescent galaxies at 1 less than z less than 2 to constrain any residual age bias.
