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

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 ...

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 ...

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 ...

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

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 ...

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 ...

When they look for violations of Einstein’s general relativity, physicists deliberately plan experiments to find nothing at all. In 1887, physicists Albert Michelson and Edward Morley performed one of ...
