The sharpest black hole collision ever detected just gave Einstein another win—and raised hopes that the next one might ...

The loudest black hole collision ever recorded has just given Einstein’s theory of general relativity its hardest test so far. The event, dubbed GW250114, produced a record-smashing signal-to-noise ...

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 ...

Planets orbiting dead stars known as white dwarfs might be able to remain habitable thanks to general relativity subtly altering their motion. When stars like our sun run out of fuel, they expand and ...
