A new physics paper proposes modifications to Einstein’s theory of relativity that could solve one of the biggest issues ...

For decades, astronomers have used distant supernovae as cosmic lighthouses to test fundamental physics and to measure the universe. For Joseph Farah, a fifth-year graduate student at UC Santa Barbara ...

The loudest collision ever recorded between two black holes has allowed scientists to test Einstein’s theory of general relativity in unprecedented detail, showing that the physicist’s predictions ...

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 ...

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 ...

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 ...

General Motors said its in-vehicle tech services generated nearly $2 billion last year. GM sells three main subscription products: safety features, in-car internet access, and hands-free driver ...

Moscow — A Russian general was killed Monday morning when an explosive device detonated underneath his car in Moscow, and investigators said Ukraine could be behind the attack, the third such killing ...
