The research also highlights an unexpected role of supermassive black holes. These cosmic giants seem to be more active than previously estimated, ejecting material up to five times further from the galactic nucleus than earlier assumptions. To reach these conclusions, scientists analyzed images of approximately 7 million galaxies by utilizing the subtle brightness of echoes from the Big Bang, known as cosmic microwave background radiation. This methodology enabled them to map gigantic cosmic filaments connecting galaxies, thus reshaping our understanding of matter distribution across the universe.
