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 ...

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 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 ...
