Since NASA launched the James Webb Space Telescope (JWST) almost three years ago, astronomers have been actively searching for clues about how galaxies grew in the early universe. The gradual and continuous cooling of the universe eventually created larger structures such as stars, galaxies, and galaxy clusters. This mismatch became a source of intrigue among researchers, who had to figure out what was wrong with their standard model. In the new study, researchers analysed data from the JWST’s Cosmic Evolution Early Release Science (CEERS) Survey, which Finkelstein leads. Biswas agreed, saying that if this value is found to have been higher in the early universe, existing models of galaxy growth and evolution may need to be reworked.
