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 ...

Everything around us, from atoms and molecules to planets and galaxies, is governed by two extraordinarily successful ...

A pair of experiments exploring bone density, designed by engineers at the University of Michigan, has left the Wallops Island, Virginia launchpad aboard a Northrop Grumman Corp. Antares rocket for ...

To live on the moon or Mars, humans will need heat and air conditioning that can operate long term in reduced gravity and temperatures hundreds of degrees above or below what we experience on Earth.

Scientists have spent decades trying to understand how gravity operates at its most basic scale. However, no theory has come close to fully explaining it. Now, though, a new theory could finally give ...

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 ...

Jeff Bezos’ rocket company gave NASA a brief taste of the moon’s gravity Tuesday, without straying too far from home. Blue Origin launched the 29 lunar technology experiments to the edge of space from ...
