Scientists have used theloudest gravitational wave signal ever recorded to put Albert Einstein’s century-old theory of ...

On January 14, 2025, a pair of black holes with nearly identical masses crashed together roughly 1.2 billion light-years away, producing a gravitational wave signal so clean and powerful that it ...

A newly detected gravitational wave, GW250114, is giving scientists their clearest look yet at a black hole collision—and a powerful way to test Einstein’s theory of gravity. Its clarity allowed ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...
