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

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 ...

Astronomers have long faced a strange contradiction: most stars are born in pairs, and ...

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.

We know that Einstein’s general relativity is, strictly speaking, wrong. That’s because it doesn’t account for quantum effects despite the fact that those e ...

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

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth.

Relativity Space is amping up its investment at NASA’s Stennis Space Center, with the company announcing today that it would lease a historic first-stage test stand to advance the development of the ...

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