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 ...

General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” of ...

Scientists have used theloudest gravitational wave signal ever recorded to put Albert Einstein’s century-old theory of general relativity to its toughest test yet. This extraordinary signal, known as ...

Scientists have confirmed, with amazing precision, Einstein's general theory of relativity. To do so, they looked at how each planet's elliptical orbit shifts over time. Albert Einstein's theory of ...

A century ago, Albert Einstein became famous. Sure, he was already well-known among physicists. But the world at large learned his name only after November 1919, when news broke that his theory of ...
