A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity ...

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 ...

New research suggests Einstein's general relativity explains the rarity of planets orbiting two suns. In tight binary systems ...

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

In theory, hundreds of circumbinary planets should have been detected by missions such as NASA’s Kepler and TESS space ...

As new and powerful telescopes gather fresh data about the universe, they reveal the limits of older theories like Einstein's relativity. When you purchase through links on our site, we may earn an ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...
