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 gravity sensor is not the kind of equipment that comes to mind when you think of treasure hunting. But this one might just be the best treasure-hunting gear out there-if you can get one for yourself ...

Neos and Lockheed Martin are building a unique gravity sensor, which is so advanced that it could find a 10-meter tall hill buried 1 km below the earth’s surface. The technology could find an armored ...

Freefalling: the new sensor compares the acceleration due to gravity experienced by two clouds of cold atoms. (Courtesy: Shutterstock/Evgenia-Fux) A quantum gravity ...
