A record breaking gravitational wave is helping test Einsteins theory of general relativity

A newly detected gravitational wave, GW250114, is giving scientists their clearest look yet at a black hole collision-and a powerful way to test Einsteins theory of gravity. Its clarity allowed scientists to measure multiple tones from the collision, all matching Einsteins predictions. That confirmation is exciting-but so is the possibility that future signals wont behave so neatly. Any deviation could point to new physics beyond our current understanding of gravity.
