The Paradox of JWST & Ancient Galaxies

When the James Webb Space Telescope spotted six early galaxies a few months ago, it challenged our understanding of cosmic evolution. These galaxies, seen 500-800 million years after the big bang, appeared brighter, larger, and more mature than expected. One such galaxy, observed 700 million years post-big bang, contained over 100 billion stars, similar to the Milky Way's count over 13 billion years. These observations contradicted our best model of universal evolution, as insufficient time had passed to gather the observed matter and convert it into so many stars. However, further analysis revealed the resilience of the current cosmological model. While some data suggested the galaxies were smaller than initially thought, others hinted they could be larger. These discrepancies suggest cosmology might need to be remodeled, potentially incorporating new elements to resolve this paradox.
