American scientists have created a substance that can make objects invisible to the eye by bending the visible light around them.
The material developed by California University researchers at Berkeley, can control light's direction of travel, Huffington Post reported.
Scientists believe the finding can help develop systems for rendering invisible people and large objects such as ships.
The study, funded by the American military, followed an earlier research at Imperial College London that was conducted with microwaves.
Invisibility comes a step closer - win an iPod!by Willemien Groot*
The Invisible Man and the trainee wizard Harry Potter have already made use of it in their adventures. Now invisibility has come a step closer for ordinary mortals. American scientists have developed a material that can diffract light in such a way that it can make an object invisible. Radio Netherlands Worldwide has decided to hold a prize competition on this theme.
The magazine Science and Nature reports that the scientists have developed a so-called metamaterial, a mixture of metals and synthetic fibres no more than a few nanometres thick. Any object covered in a layer of this metamaterial can, in theory, be made invisible. Objects such as the computer screen you are now looking at are, after all, only visible because they reflect light. If, for example, your screen allowed light to pass through it, or turned it off, you would see the light behind it - thus creating the illusion that the screen has disappeared.
