Scientists Punch a Hole in the Fabric of Time with a “Time Cloak”
Researchers  at Cornell have designed, built and demonstrated the first “cloak” that  hides events in time. The process relies on similar methods of  distorting electromagnetic fields as invisibility cloaks, but it  exploits a time-space duality in electromagnetic theory: diffraction and  dispersion of light in space are mathematically equivalent. Scientists  have used this theory to create a “time-lens [that] can, for example,  magnify or compress in time.”
The time cloak takes two of those  lenses and arranges them so that one compresses a beam of light while  the other decompresses it. That leaves the beam seemingly unchanged, but  the diffraction and dispersion actually “cloak” small events in the  beam’s timeline. Right now, the cloak can only last for 120 nanoseconds,  and the theoretical max for the current design measures just  microseconds. But the prospect of being able to exist outside of time,  even for just a few microseconds, should be enough to make even the most  jaded tech nerd giggle at the possibilities.
