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

In 1905, Albert Einstein revolutionized physics by demonstrating that time is not absolute but relative to the observer's ...

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.

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 ...

One such mystery, described in a recent paper in The Astrophysical Journal Letters, concerns circumbinary exoplanets—or ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

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

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

Their tests spanned the entire life cycle of the collision: inspiral, merger, and ringdown. Remarkably, the constraints were ...
