# Time Cloak Hides Messages In Laser Light

![](<https://futurism.com/wp-content/uploads/2014/11/dn26627-1_300.jpg>)

- A time cloak makes an event disappear in time. It works by manipulating light traveling along an optical fibre
- Scientists discovered that photons' paths can be tweaked to create brief gaps where information can safely hide
- The cloak delivers the messages and it also successfully fends off outside attempts to scramble the information
