Gravity used to be the most down-to-earth of ideas, the thing that kept apples falling and planets in line. Now a growing ...

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 ...

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 ...

Physicists at CERN have discovered that antimatter falls down. Sure, it sounds like an obvious thing, but scientists haven’t yet been able to confirm that it responds to gravity in exactly the same ...

Is gravity a quantum phenomenon? That has been one of the big outstanding questions in physics for decades. Together with colleagues from the UK, Anupam Mazumdar, a physicist from the University of ...

When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of ...

The researchers say their experiment was inspired by a levitating frog. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Chinese scientists have ...

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 ...

In context: Antimatter is a substance composed of antiparticles with an opposite electric charge compared to the corresponding particles in "ordinary" matter. Despite its opposite nature, antimatter ...

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 ...
