Reasoning University professor Dr Nugent has produced a study in which he puts forward a theoretical calculation of how light could be bent to make objects invisible. He theorises that if light bends round an object rather than hitting it, the object will appear invisible. He points out that the science he is using is well established. Light is bent when it travels through water as is demonstrated by the fact that the fish you see in the water are not in fact where you think they are. Our brains ‘think’ that the light travels in a straight line. An invisibility cloak would be a much more sophisticated application of the same science. The professor stresses that a design is still a long way off and that a lot of effort and money will have to be spent before his concept could be developed into a workable device.
