When we want to weigh something, the process is simple. We place it on a weighing machine or on a traditional balance. The number appears and we instantly know how heavy the object is. But imagine a ...

It’s been 120 years since Henry Cavendish measured the gravitational constant with a pair of lead balls suspended by a wire. The fundamental nature of gravity still eludes our best minds - but those ...

New measurements of the gravitational constant confirm that the official value needs to be increased and, as John Moore reports, could explain what went wrong in a previous experiment. Ever since ...

Cavendish-like: A schematic diagram of the proposed experiment on gravitational interaction between two torsion balances. Two torsion pendula are placed with their equilibrium orientations (dashed ...

An update to an experiment run by Henry Cavendish in 1773 could be a cheaper and faster way to spot a potential dark matter ...
