DARPA’s Invisibility Cloak?

Yes, it’s true. Thanks to DARPA funding, a group of scientists have done the impossible. They’ve invented an invisibility cloak.

A Working Invisibility Cloak?

We first reported on invisibility cloak technology back in October 2011. This technology is a little different. But don’t get too excited…this invisibility cloak only works for 50 picoseconds…in other words, 40 trillionths of a second. That’s not enough time to blink let alone sneak through the hallways of Hogwarts. While some improvement is possible, it would apparently take a gigantic machine (18,600 miles long!) to make this invisibility cloak last for a complete second.

Still, it’s not all for naught. The invisibility cloak, developed with DARPA funding, could help improve fibre-optic communications security. Then again, it could also be used to hide computer viruses as they’re passed into high-speed data streams. Here’s more on this new invisibility cloak from Fox News:

We see events happening as light from them reaches our eyes. Usually it’s a continuous flow of light. In the new research, however, scientists were able to interrupt that flow for just an instant.

Other newly created invisibility cloaks fashioned by scientists move the light beams away in the traditional three dimensions. The Cornell team alters not where the light flows but how fast it moves, changing in the dimension of time, not space.

They tinkered with the speed of beams of light in a way that would make it appear to surveillance cameras or laser security beams that an event, such as an art heist, isn’t happening…
