3. Time Invisibility Hides Events From Time

No, really. Time invisibility. That's hiding events from time.

Whilst it may or may not be possible for science to deliver a fully fledged invisibility cloak a la Harry Potter, scientists have put their efforts into finding a way of hiding events from time instead.

Time cloaking is based on pretty much the same principle as "regular" invisibility, which usually works by bending light around an object. The time invisibility cloak essentially creates a hole in time for the event to pass through unnoticed. It works by splitting a light beam and diverting it through a medium before putting it back together at the other end with a time lens, with no record of what went on in between. With the beams sped up and slowed down, it creates a gap in which an event can be masked.

Just like the invisibility cloak allowed Harry to pass through Hogwarts undetected, time cloaks could enable us to send encoded data that would be undetectable to hackers.
