Nearly twenty years ago, satellites detected an unusual gravitational signal off the coast of Africa, revealing a deep ...

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.

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 ...

The world's most sensitive table-top interferometric system—a miniature version of miles-long gravitational-wave detectors like LIGO—has completed its first science run.

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 ...

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 ...

Scientists review research on gravitational wave detectors as a historical example of quantum technologies and examine the fundamental research on the connection between quantum physics and gravity.

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 ...

Is gravity a quantum phenomenon? That has been one of the big outstanding questions in physics for decades. Physicists have proposed an experiment that could settle the issue. However, it requires ...
