An Invisible Cloak is Also Being Created

Becoming invisible (alongside flying, burning in fire, seeing beyond walls, etc.) is considered one of the unattainable powers of humans in science fiction stories. Herbert George Wells narrated a story in 1897 (The Invisible Man) in which the protagonist becomes invisible by drinking a liquid. Subsequently, stories have recounted cloaks that make humans invisible when worn. However, scientists say that the creation of this cloak has come very close to reality. A group of scientists announced that they have created a small cloak using very small rectangular pieces of gold metal that takes the shape of objects like human skin and makes them invisible. According to Reuters, this cloak, although made on a microscopic scale, is believed by researchers to be applicable to larger objects as well. This coating can scatter light waves from an object, making it impossible for the human eye to see it. Jean Zheng, head of the science and industry section at the U.S. National Laboratory at Berkeley, states that it would take between five to ten years for this technology to be practically usable, but there are no serious obstacles to achieving it. This technology uses meta-materials, or metamaterials, which are not naturally found in nature. Yingjie Ni, a professor at the University of Pennsylvania and designer of this project, says that when we can make curved objects appear flat, we can also make them completely invisible. Ni states that this technology will not only be used in the military (to hide large objects like tanks or even soldiers) but can also be applied in the fashion and beauty industry: imagine if facial wrinkles were no longer visible or belly fat was hidden from sight!
