We have all seen invisibility used in science fiction movies. The spies use invisible car to flee away from the location. Well, now scientists are working to make this a reality.
An article in Popular science magazine shows us how it can be a reality and what are the theories of the scientists . The trick is to use metamaterial, a complex hybrid structure of metal and insulator that makes light move around an object like air flowing over an airplane wing.
In a process called refraction, these materials interact with light in such a way that it travels faster through the metamaterial than it does through a vacuum, the famed c in Einstein’s special theory of relativity. Properly tuned, the light emerges from the shield as if there were no object present.
