For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational ...

Mind = blown.

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 ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

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 ...

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 ...
