A new physics paper proposes modifications to Einstein’s theory of relativity that could solve one of the biggest issues ...

Three physicists have proposed a modification to Einstein’s general relativity that, if confirmed, could eliminate the ...

A Gravity Theory That Could Rewrite the Universe’s First Moments The first fraction of a second after the Big Bang has always ...

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 ...

A new experiment with momentum-entangled helium atoms could help unite quantum mechanics and general relativity.

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 ...

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

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 ...

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 ...
