Measuring the strength of gravity is extraordinarily difficult, and different experiments have always disagreed – but a new ...

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 ...

After a 10-year effort, physicists got a value for “Big G” that does not settle the debate over one of nature’s hardest ...

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 ...

Gravity is the weakest of the fundamental forces, but it’s the only force that operates over very long distances. Hence, planets orbit stars, stars form galaxies, and galaxies cluster. Gravity also ...

When astronaut Alexander Gerst squeezed a specially designed instrument aboard the International Space Station in 2018, his ...

A decade-long effort to measure one of physics’ most fundamental constants culminates in a moment of uncertainty and revelation.
