Scientists could soon test Einstein's theory of general relativity by measuring the distortion of time. General relativity states that gravity is the result of mass warping the fabric of space and ...

The earliest test of Albert Einstein's general theory of relativity took place just four years after he published it. During ...

Researchers are using black hole “shadow” images to test whether Einstein’s relativity remains unshakable. With ...

The Event Horizon Telescope only recently gave us the first images of the environment immediately surrounding a black hole.

Pairs of black holes have been detected in the past through their gravitational effects, but until now, scientists have never ...

General Relativity, Einstein’s seminal theory of gravitation, remains a pillar of modern physics by describing gravity as the curvature of spacetime. Nonetheless, persistent questions—ranging from the ...

Two recently observed black hole mergers, occurring just weeks apart in late 2024, have opened an extraordinary new window ...

Interstellar comet 3I/ATLAS, which originated outside our solar system, has reportedly confirmed one of Albert Einstein's ...

For the first time, scientists have detected two black hole mergers with spins so unusual they may reveal a new generation of ...

Perhaps the greatest, mind-bending quirk of our universe is the inherent trouble with timekeeping: Seconds tick by ever so slightly faster atop a mountain than they do in the valleys of Earth. For ...
