This has got to be an example of technology moving so fast that it literally trips over itself. Over the past several months we have been hearing more and more about tech being studied and developed that would allow a functional "invisibility cloak". Well it seems now that such a device may never happen. Why? Well it is not because a massive hole has been found in the concept, no, it's because a group of Chinese researchers have proposed a theoretical "anti-cloak" that would partially cancel the effect of the invisibility cloak, making the invisibility cloak technology partially infective. Their "anti-cloak" would be a material with optical properties perfectly matched to those of an invisibility cloak. Before you start cashing in your invisibility cloak stock, lets look at one of the major problems of a "truly" invisible material. Something that bends light around itself doesn't absorb any and doesn't reflect any. If you put a sheet of this material over yourself you would become blind. What the Chinese researchers have done is to solve this problem. Envisioning this problem, they developed in theory a way to cancel out small sections of the "cloak" so that you could see out.
Ingenious yes, but considering that we have only been able to bend certain wavelenghts of light so far and only in a lab, making "accessories" is something way on the fringe.
