How researchers propose to search for dark matter. The torsion balance is a geometrically asymmetric structure with a hollow “spherical shell” on the left and a “solid sphere” on the right. The impact ...

A tabletop instrument sensitive enough to measure a twist smaller than a trillionth of a degree has just become the world’s most powerful direct probe of ultralight dark matter. In a study released in ...

Torque isn’t just for mechanics — it’s a key player in physics, engineering, and even everyday life. From balancing a seesaw to tightening a bolt, understanding torque helps you control stability and ...
