In a groundbreaking discovery, scientists have detected the most massive black hole merger ever observed, forming a black hole 225 times the mass of the sun. This unprecedented event, captured by the LIGO-Virgo-KAGRA gravitational wave detectors, challenges existing theories of black hole formation and suggests the existence of cosmic phenomena previously thought impossible. The merger, located 10 billion light-years away, marks a significant advancement in our understanding of the universe and poses new questions for astrophysics.
