It's no longer just movie magic. Britain's Ministry of Defence has developed new scanning technology that lets it see through walls or look underground.
The invention, referred to as the "new quantum gravity detector," detects changes in gravity by working with lasers to freeze atoms. It then measures how particles are affected by the gravitational pull of objects close to it. Scientists then draw a 3-D map and can see anything from people to pipes on the other side of a wall or underground.
Neil Stansfield, of the Defence Science and Technology Laboratory, said the tech could lead to new navigation systems, eventually replacing GPS satellites with a safer alternative that can't be hacked, jammed or spoofed.
Stansfield said in a BBC documentary, “We are not sending out a wave of any form, we are detecting the gravitational influence on an object. There’s nothing that we are sending out that can be interfered with.”
But is using the device practical? Some British citizens are concerned the tech will be used to spy on people in their own homes, while others are saying it could be valuable tool in terms of national security.
It was also noted that it could be used by construction and building companies to locate underground pipes, saving time money and effort on certain projects.
There's a BBC documentary detailing all of Stansfield's project Greenglow, which began hoping to answer the question: "Is it possible to control gravity?" See a clip of it below and check your local listings for air times.
