Invisibility

Recently researchers at Duke University have created a metamaterial with unique physical properties. The material manipulates light to hide an object behind the "cloak". The surface of the material must be much smaller than the wavelengths of the light being passed through it. The cloak was covering a bump and when infra red light was shone on the material the bump was concealed as if the bump were never there. It only took nine days for the researchers to create the material and about 1 dollar in circuit boards to create the invisibility cloak. The researchers also stated that it would cost close to nothing to commercialize the technology. I feel that this breakthrough is just in the beginning stages and has a long way to go until people start having a huge demand for the product. At this time I don't see much use for the product other than the concealment of objects. I can see a need from the military in the form of making tanks and other vehicles invisible to the naked eye. I don't think the cloak can make humans invisible but with the way that science and technology is evolving I would not be surprised about any such advancements. It is a very intriguing idea and one that many people will follow. I fill if invisibility is ever achieved it will be one of the biggest discoveries of the century but i believe it is very far in the future if ever.
