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 ...

For more than 200 years, scientists have struggled to pin down the exact strength of gravity — and one physicist spent a decade chasing the answer while keeping his own results hidden from himself.

A new discovery suggests gravitational fields can enable matter to become quantum entangled — and that's even if the concept of quantum gravity does not exist. The idea comes from two London-based ...

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 ...

Physicists have just dropped a new precise measurement for gravity. The newly published value for the strength of gravity, known as “G” or “Big G”, is significantly smaller than some previous ...

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 ...
