As the James Webb Space Telescope (JWST) examines small and bright galaxies in the early universe, it may shed light on dark matter – the universe’s most mysterious matter. That is the conclusion of scientists at the University of California, who conducted a simulation of the cosmos that tracks the formation of small galaxies – … Read more
