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

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 ...

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.

It's not a fluke: For the third time, the LIGO gravitational wave observatory has detected ripples in space-time caused when two black holes circle each other at mind-bending speeds and collide. The ...

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 ...

A bizarre "cosmic glitch" in the theory of how the gravity of the universe works may have been mended. The strange glitch in Einstein's description of gravity in his theory of general relativity may ...

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, ...

Humans have been studying total solar eclipses for millennia to better understand the cosmos. Total eclipses have helped prove Einstein's theory of relativity and led to the discovery of helium. Here ...

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