"Unveiling the Origins of the Universe: New Insights from Bright Galaxies and Ancient Ultraviolet Light"

Astrophysicists are using the James Webb Space Telescope to search for tiny, bright galaxies near the beginning of the universe to test theories about dark matter. New simulations suggest that interactions between gas and dark matter could have made early galaxies much brighter than previously thought. If the telescope finds these bright galaxies, it would confirm the cold dark matter model, but if only faint galaxies are found, it could challenge current theories about dark matter and prompt a reevaluation of our understanding of the universe's formation.
