An international team of astronomers has conducted a new test of Albert Einstein's famous theory of general relativity (GR), finding that it works even in extreme gravitational environments, according ...

Astronomers have identified a potential ultra-fast pulsar spinning every 8.19 milliseconds close to Sagittarius A*, the ...

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 ...

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

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 ...

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 ...

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

If the universe were a soup, it would be more of a chunky minestrone than a silky-smooth tomato bisque. Sprinkled with matter that clumps together due to the insatiable pull of gravity, the universe ...

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 ...
