Researchers from Columbia University and Breakthrough Listen, a scientific research program aimed at finding evidence of civilizations beyond Earth, have published new results from the Breakthrough ...

Pulsars are a special class of neutron stars that spin very quickly on their axes, releasing pulses of radio waves. These ...

Confirming a pulsar star would enable unprecedented tests of General Relativity. Such a discovery would revolutionize physics ...

LIGO's GW250114 signal tests Einstein's relativity, revealing black hole properties and confirming key theorems in ...

The sharpest black hole collision ever detected just gave Einstein another win—and raised hopes that the next one might ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

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

Learn why only 14 out of over 6,000 exoplanets orbit two stars, and how Einstein’s general theory of relativity may be to blame.

Planets orbiting dead stars known as white dwarfs might be able to remain habitable thanks to general relativity subtly altering their motion. When stars like our sun run out of fuel, they expand and ...

One day, a mind-bending device called the gravity telescope might bring us visceral pictures of exoplanets far beyond our solar system. Monisha Ravisetti was a science writer at CNET. She covered ...
