The U-Cell Model Prediction Omegaₘ=0. 3166: Consistency with 33 Cosmic Chronometer H (z) Measurements

Key Points

To assess the consistency of the U-Cell Model prediction of omega_m=0.3166 with 33 cosmic chronometer H(z) measurements.
Utilized 33 cosmic chronometer H(z) measurements from Moresco 2022.
Applied analytical marginalization for H_0.
Conducted model-independent tests of the UCM expansion prediction.
Achieved chi²/dof of 14.534/32, indicating a good fit.
Delta chi² of 0.00 compared to ΛCDM shows no significant deviation.
BIC increase of +3.5 highlights the predictive power of the UCM model.

Abstract

Tests the UCM prediction Omegaₘ=0. 3166, w=-1 against 33 cosmicchronometer H (z) measurements (Moresco 2022, z=0. 07-1. 97). H₀analytically marginalised. Results: chi²/dof=14. 534/32=0. 454, Deltachi²=0. 00 vs ΛCDM, ΔBIC=+3. 5. The CC method measures H (z) directly without standard candles or sound horizon, making this themodel-independent test of the UCM expansion prediction.
