Reevaluating the Big Bang's 'Echo' Signal
A new study questions the traditional understanding of the Cosmic Microwave Background (CMB) as a remnant of the Big Bang, suggesting that early-type galaxies (ETGs) might account for some or all of the CMB, potentially requiring a revision of the universe's history. The findings, based on recent data from the James Webb Space Telescope, imply that the formation timeline of galaxies and the interpretation of cosmic radiation may need to be reconsidered, although the research is still preliminary.
