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 measured the smallest gravitational field ever recorded, in an experiment that could help in the search for a unified theory of physics. Of the four fundamental forces known to physics ...

Want to make ultra-precise measurements of the strength of gravity? There is an app for that — or at least a quantum device called the “gravimeter,” which functions as a scaled-down version of the ...

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

For much of the twentieth century, scientists expected the expanding universe to slow over time. The opposite turned out to ...

My eighth grade science teacher had a great idea for a weight loss program: just send people to the moon. Gravitational pull is different on every planet, moon and star. On the moon, we would weigh ...

Heavy duty: Ultracold atoms could soon be making gravity anomaly maps like this one of Australia. (Courtesy: Australia Geoscience) The curvature of a gravitational field across a distance of about 1 m ...

The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at ...
