A group of Chinese scientists think they can use carbon nanotubes in shifting layers to actually create an invisibility cloak. The theory of it was proven last year, when a separate team of scientists found they could render a very small object invisible to a microwave, but it required very precise positioning of the tubes. The Chinese scientists are saying they can layer the nanotubes to achieve the effect of invisibility to regular light waves. The shifting of the layers will not reflect much light, in fact light will bend around it. The real question is how they’re going to get the nanotubes to surround an entire Klingon Bird of Prey, and then recede so they can fire their photon torpedoes. Obviously important practical problems still remain.
