Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of ...

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 ...

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 ...

The sharpest black hole collision ever detected just gave Einstein another win—and raised hopes that the next one might ...

The team examined the remnant black hole’s “Kerr nature”, the mathematical description of a rotating black hole in general relativity. By analyzing the dominant quadrupolar mode and its overtone, they ...

Einstein was awarded the 1921 Nobel Prize for a theory that half of the people might not even have heard of. His Theory of ...
