The invisibility cloak for TIME: Experts create a cloaking device capable of hiding entire events in 'bubbles'

The quest for a true invisibility cloak, seen in films such as Harry Potter, is the holy grail for physicists. To create their ‘temporal cloak’, researchers separated strands of frequencies in light before changing their respective height. This created a gap, in which physicists could insert and send hidden data messages The technique, called ‘temporal cloaking’ was developed at the Purdue University using lasers and fibre optics, and is reported in the journal Optics InfoBase. If a gap created between the light strands was large enough, a person could walk through the centre undetected, and appear in another location. And in theory, by changing the speed on multiple strands of light could create a series of gaps into which multiple pieces of data could be hidden.
