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.

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

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

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 ...

BOULDER- Black holes, time travel and E= mc^2. They are all related to Albert Einstein's Theory of Relativity. How many of us, though, can actually explain any of it? This year, Einstein's theory ...

Two researchers have found an explanation for why we find almost no exoplanets orbiting binary stars. According to them, ...

Addressing a controversy first raised around 1910, two physicists have performed experiments with the aid of an engineer that validate anew the special theory of relativity’s limitations on the speed ...

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

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

It was co-written with his lifelong friend, the Swiss engineer Michele Besso. LONDON -- A rare manuscript by Albert Einstein that changed the course of modern science was just sold for over 13.3 ...
