As strange as it may sound, invisibility actually may be a possibility in the not too distant future. It won't occur by donning a special coat or eating a pill ... but invisibility may be a reality before too long. This is according to Dr. Ulf Leonhardt, a professor of theoretical physics at St. Andrews University in Scotland. Leonhardt told Reuters that the way invisibility likely will work is the manner in which it functioned in for the Invisibile Woman, one of the Fantastic Four superheros of Marvel Comics. Invisibility really is an optical illusion. It is like water circling around a stone, according to Leonhardt. The water will flow at and around the stone and leaves nothing behind, as if it were not even there. If you replace water with light you would see the scenery behind the object being cloaked and not the object itself. He presented his research in papers presented in Science magazine. He imagines that initial cloaking devices will be used to bend both radar waves or the electromagnetic waves and electromagnetic radiation. In theory, he believes that these devices could be used to protect people from radiation emitted from mobile phones. |
