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 ...

A centuries-old experiment could help accelerate the search for new and exotic particles, including those that make up dark matter. In 1773, British scientist Henry Cavendish set up a simple ...

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 ...

Figure 4 The traditional Cavendish experiment for measuring the strength of gravity was a torsion balance with an “optical” ...
