How the Loudest Gravitational Wave Opened a New Window into Black Holes

Scientists have used the loudest gravitational wave ever detected, GW250114, to probe the event horizon of a newly formed black hole. By isolating the signal's direct waves with a groundbreaking analysis, researchers measured the black hole's rotation and surface gravity with unprecedented precision. The discovery offers a powerful new way to test Einstein's general relativity, explore quantum physics under extreme conditions, and better understand how black holes warp the fabric of spacetime.
