Merging black holes with a total mass of 100 Suns generate gravitational waves and may emit gamma-ray bursts
Scientists have detected gravitational waves from colliding black holes so massive they shouldn't exist according to current theory, raising urgent questions about how these cosmic behemoths formed in the first place. The collision, which produced a final black hole weighing as much as 100 suns, also appeared to trigger a burst of gamma rays—a phenomenon that challenges physicists' understanding of what happens when black holes merge. If confirmed, the finding could reshape models of stellar death and black hole evolution across the universe.
