In the hunt for extraterrestrial life, we usually look for planets orbiting sun-like stars and icy moons. But there is another possible candidate—planets circling white dwarfs, the hot, dense remnants ...

Physicists have unlocked clues hidden within gravitational waves that reveal how black holes drag spacetime along with their spin.

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 ...

For decades, one of the biggest questions in cosmology has remained frustratingly out of reach: what, if anything, existed before the Big Bang? Now, researchers are using advanced computational ...

A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity ...

General relativity presents gravitation as the manifestation of spacetime curvature produced by matter and energy. In the strong-field regime, this theory predicts the formation of black holes: ...
