Pentagon Physicists Invent Time Cloak

Pentagon Time Cloak – More science fiction becoming reality, as physicists supported by the Pentagon say they have created a ‘time cloak’ which they say makes an event briefly undetectable.

Close to what could be an invisibility cloak the physicists say it is the next step in camouflage technology. The ‘time cloak’ “manipulates the flow of light in such a way that for the merest fraction of a second an event cannot be seen,” per the published paper in the ‘Nature’ science journal.

“Our results represent a significant step towards obtaining a complete spatio-temporal cloaking device,” says the study leader Moti Fridman from Cornell University in New York.

Though the time cloaking device is on the most minimal basis it is a breakthrough in physics. At its most basic explanation the device can cloak a 40 picosecond burst of a laser beam. It is cloaked by other separate red and blue beams of light traveling through fiber optic strands and a lens, that travel at 50 picoseconds. A single picosecond equals one millionth of a second.

It was explained by Robert Boyd and Zhimin Shi with the New York University of Rochester as if a line of traffic was cut off by a passing train then when the train passed the stopped traffic would speed up to catch up with the cars that made it by the oncoming train.

The next step for the physicist to start to try to widen the time gap of undetectability from picoseconds to microseconds and onto milliseconds.
