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 ...

Physicists have long suspected that gravity might have a hidden quantum side, but for decades the idea has been more mathematics than measurement. A new proposal for a tabletop experiment now suggests ...

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.

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to be folded neatly into the quantum rules that govern the rest of nature. Now a convergence of bold ...

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.

The parabolic flight travels up and down several times on a trajectory resembling an arch, providing 22 seconds of zero ...

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 ...

NASA is calling on college undergraduates interested in performing reduced gravity experiments onboard the agency’s “Weightless Wonder” aircraft to submit their proposals by Monday, Oct. 30. The ...
