A cloak made from mirrors is able to make it appear to an observer that the subject is frozen in time.
While the conventional idea of an invisibility cloak is a device or garment that renders the subject invisible, researchers at Northwestern University have come up with a new type of cloak made from mirrors that can put time on hold for any objects inside it. A clock for example would continue to operate normally but to the external observer it would appear to have stopped.
The 'temporal cloak' currently only exists on the drawing board but according to scientists there is nothing to stop it being built using materials available today. The advantage of being able to hide something in this way could prove invaluable in a number of applications including on the battlefield, making this of prime interest to military technology specialists.
"Researchers at Northwestern University have designed an invisibility cloak that can temporally hide objects for an indefinite period of time."
