Learn how researchers used Einstein’s theory of general relativity to create the most accurate simulations to date. Think of a black hole, and you might imagine a literal dark hole, but contrary to ...

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 ...

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth. Of the more ...

On January 14, 2025, the Laser Interferometer Gravitational-wave Observatories (LIGOs) recorded a cosmic tremor unlike any before. Named GW250114, the signal was the ‘loudest’ gravitational wave ...
