The best way to find buried treasure may be with a quantum gravity sensor. In these devices, free-falling atoms reveal subtle variations in Earth’s gravitational pull at different places. Those ...

A novel quantum sensor that measures gravity changes by detecting variations in the travel time of falling atoms has been tested in a first of its kind experiment aboard an Australian navy ship. The ...

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 ...
