Invisibility Cloak Created by Scientists

Researchers from Purdue University in Indiana have developed a cloak that is able to hide data by manipulating a stream of light.
Many sci-fi movies have shown humans becoming invisible. While it's not possible in reality today, we could be getting closer.
Researchers from Purdue University in Indiana have developed a cloak that is able to hide data by manipulating a stream of light.
Referred to as a time cloak, the optical fibers manipulate how light interacts with them, making a hole in time where disturbances to the light path become invisible.
During the study, the cloak hid almost half of the data that was put in the light beam’s path.
Ortwin Hess, a physicist at Imperial College London who was not involved in the study said: “It shows how beautiful the space-time principles are that can be used in optics....now we can change the way light, and thus information, behaves in space and time.”
A variety of different cloaking technologies have been developed.
Thermal cloaking makes objects invisible to heat energy.
By redirecting the heat around a center portion using rings of low conductivity, researchers from the Karlsruhe Institute of Technology in Germany have created a thermal cloaking system.
