(Phys.org)—A team of researchers from France, the U.S. and Italy has found evidence from the Tohoku-Oki earthquake that sensors that measure changes in gravity might offer a way to warn people of ...

When it comes to understanding the fundamental forces of the universe, gravity is by far the most intuitive. It’s the force that brings us splashing down after jumping from a diving board and the ...

The portable gravimeter developed by Canberra-based Nomad Atomics uses quantum sensing to precisely measure gravitation, but is little larger than a shoebox and rugged enough to cart around on ...

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 ...
