Physicists have long suspected that gravity might have a hidden quantum side, but for decades the idea has been more ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

Scientists have evidence for a sea of ripples in space-time, called the gravitational wave background. Their experiment used dead, spinning stars to hack our galaxy and turn it into a wave detector.

COLUMBIA, S.C. — We have two holidays to celebrate this week - Saint Patrick’s Day and the start of spring. Today’s experiment ties in both of those holidays. The experiment, sometimes called "walking ...

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 ...

A proposed experiment hopes to find gravitational waves, which are hypothetical fluctuations in the fabric of spacetime. All it needs is three satellites orbiting the Sun, and lasers capable of ...

When incredibly massive objects collide violently in space, they send out ripples in space-time that reverberate through the cosmos for billions of years. Long after the collisions happen, these ...

A recent experiment at Fermilab has delivered intriguing results that challenge standard predictions, adding fuel to the ongoing quest for quantum gravity. These findings, which involve the behavior ...
