A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity ...

Quantum Gravity and General Relativity represent two foundational yet traditionally disparate pillars of modern physics. General Relativity, Einstein’s seminal theory, elegantly encapsulates ...

Add Yahoo as a preferred source to see more of our stories on Google. A illustration shows a quantum experiment investigating gravity on a tiny scale. Scientists have determined a way to measure ...

General Relativity, Einstein’s revolutionary theory of gravity, reinterprets gravitational interactions as phenomena emerging from the curvature of spacetime rather than as forces in the traditional ...

At the center of the Milky Way, close to the pull of a supermassive black hole, astronomers have found a strange new radio signal that behaves like a slow, steady clock. This object is more than an ...

June 21 (UPI) --The theory of general relativity states that objects and their gravitational pull distort the spacetime around them. The phenomenon explains the gravitational lens effect, the bending ...

A single star, careening around the monster black hole in the center of the Milky Way, has provided astronomers with new proof that Albert Einstein was right about gravity. As light escapes a region ...

An artist's visualization of the star S0-2 as it passes by the supermassive black hole at the galactic center. As the star gets closer to the supermassive black hole, it experiences a gravitational ...

In 1915, the universe was small and static. Space was smooth. Gravity pulled things to the ground. At least that’s the way it was in the minds of all but one exceptional physicist — Albert Einstein.
