A device that can measure the gravitational force on a particle that weighs less than a grain of pollen could help us understand how gravity works in the quantum world. Despite keeping you stuck to ...

Quantum scale gravity has long been a mystery to physics, but things could be starting to change. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

Physicists have measured the gravitational field of a smaller object than ever before, a gold sphere with a mass of about 90 milligrams. This could help us understand how gravity fits together with ...

Albert Einstein’s theory of general relativity has been remarkably successful in describing the gravity of stars and planets, but it doesn’t seem to apply perfectly on all scales. When you purchase ...
