Summary
University of Ottawa researchers said their CCC+TL cosmology matched several major observations while estimating the universe at 26.7 billion years old, nearly double the standard 13.8 billion.
The model replaces dark matter and dark energy with time-varying physical constants and modified Einstein-Friedmann equations, aiming to explain cosmic expansion, galaxy motion and early-element abundances in one framework.
In tests, it reproduced hydrogen and helium abundances, fit cosmic-chronometer expansion data, and matched rotation curves for all 175 galaxies in the SPARC database without invoking dark matter.
The team also reported proof-of-concept agreement for the Bullet Cluster and supportive supernova time-dilation results, though the latter remains under review and the cluster work needs deeper study.
At high redshift, CCC+TL would make the universe about 4.6 billion years old instead of 300 million during cosmic dawn, potentially easing the James Webb early-galaxy puzzle; upcoming GLIMPSE observations above redshift 50 could test that claim.
