Resolution of the JWST Surface Brightness Crisis (Tolman Test) via Vacuum Viscosity Model (η≈0.14)

Key Points

The research aims to resolve discrepancies in surface brightness measurements of high-redshift galaxies as observed by the JWST.
Extended the Primary Energy theory to address surface brightness issues.
Analyzed how surface brightness behaves differently than predicted by ΛCDM.
Applied the vacuum viscosity model to reconcile data with theoretical predictions.
Surface brightness observed to decrease as (1+z)^{-1}, contradicting the (1+z)^{-4} behavior indicated by ΛCDM.
Provides a solution to the Tolman test crisis without invoking unusual galaxy evolution scenarios.

Abstract

This work extends the Primary Energy theory (Paygachkin, 2026, Zenodo: 10. 5281/zenodo. 18243276) to explain the anomalous brightness of high-redshift galaxies observed by the James Webb Space Telescope. The model demonstrates that surface brightness falls as (1+z) ^-1 rather than (1+z) ^-4 predicted by ΛCDM, providing a natural solution to the Tolman test crisis without requiring exotic galaxy evolution scenarios.
