Stephen Hawking's 50-year-old theorem on how black holes merge together has been successfully tested thanks to huge advances in gravitational wave astronomy, which helped astronomers catch the waves ...

An illustration imagines GW250114, a powerful collision between two black holes observed in gravitational waves by the LIGO experiment, from the perspective of one of the black holes as it spirals ...

The Laser Interferometer Gravitational-Wave Observatory (LIGO) has detected new gravitational waves from a merger that resulted in a black hole 63 times the mass of our sun. Interestingly, it was ...

An eon ago, when only microbes dwelled on Earth, a pair of black holes some 1.3 billion light-years beyond the solar system spiraled toward each other until they crashed. The two became one big black ...

This artwork imagines the ultimate front-row seat for GW250114, a powerful collision between two black holes observed in gravitational waves by the US National Science Foundation LIGO. It depicts the ...
