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

The curious minds at What If examine overwriting Einstein’s theory of relativity with time travel, imagining paradoxes, ...

Ripples in space-time from a pair of merging black holes have been recorded in unprecedented detail, enabling physicists to test predictions of general relativity ...

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 ...

Einstein was awarded the 1921 Nobel Prize for a theory that half of the people might not even have heard of. His Theory of Relativity, though world-changing, was not cited. Yet while delivering his ...

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

Confirming a pulsar star would enable unprecedented tests of General Relativity. Such a discovery would revolutionize physics ...

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

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.

Virginia man accused of double murder while having an affair, family au pair testifies Trump sues the IRS and Treasury ...

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.

Albert Einstein won the 1921 Nobel Prize in Physics, but not for relativity—the theory that made him famous. This article unpacks why the Nobel committee hesitated: Alfred Nobel’s rules, distrust of ...
