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

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational ...

Learn why only 14 out of over 6,000 exoplanets orbit two stars, and how Einstein’s general theory of relativity may be to blame.

From the fall of an apple to the glow of the farthest known star, gravity quietly choreographs almost everything that happens ...

Albert Einstein won the 1921 Nobel Prize in Physics, but not for relativity—the theory that made him famous. This article ...

Scientists could soon test Einstein's theory of general relativity by measuring the distortion of time. General relativity states that gravity is the result of mass warping the fabric of space and ...

One such mystery, described in a recent paper in The Astrophysical Journal Letters, concerns circumbinary exoplanets—or rather, the shortage thereof—in the now 6,000+ exoplanets confirmed to date.

LIGO's GW250114 signal tests Einstein's relativity, revealing black hole properties and confirming key theorems in ...

For more than a century, Einstein’s relativity has set a hard speed limit for the universe, with light as the ultimate ...

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 ...
