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 ...

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 ...

Exactly 99 years after Einstein’s theory of general relativity was proven right in our own solar system, scientists show that it also holds true for entire galaxies.

Under certain extreme conditions Einstein’s general theory of relativity seems to violate determinism, according to an international team of physicists. The group has shown that in a universe ...

According to general relativity, even empty space-time, devoid of stars and galaxies, can have a life of its own. Ripples known as gravitational waves can propagate across space in much the same way ...

A new measurement of gravity at small scales hints at an alternative to billion-dollar experiments for the future of physics.

Einstein’s general theory of relativity can be summed up in just 12 words: “Space-time tells matter how to move; matter tells space-time how to curve”. But this short description from the physicist ...
