The Qatar General Organisation for Standards and Metrology (QGOSM) announced the completion of the first measurement of absolute gravitational acceleration in Qatar. This measurement was taken as part ...

Physicists in California have loaded a bunch of ultracold caesium atoms into the back of a van and driven them up a hill to demonstrate how quantum interference can be used to measure gravity outside ...

In 1797 Henry Cavendish, one of Great Britain’s leading scientists, built a contraption to weigh the world. At the time, Earth’s mass was unknown, as was its composition. Was it mostly solid rock? Did ...

Wide binary stars with separation greater than about 2000 astronomical units are interesting natural laboratories that allow a direct probe of gravity at low acceleration weaker than about 1 nanometer ...

The spinoffs from gravitational wave detectors are not just new scientific discoveries. The technology also has other uses. A good example of this is the gravity-measuring mission, GRACE Follow On, ...

Imagine you want to study what happens when an object accelerates. Oh, this is way before any of that internet stuff—also, no computers or electronics. In fact, let's say it's the year 1780. What do ...
