Now when I say closer, I mean that scientists have actually made something appear invisible, it just happens to be nano sized(one billionth of a metre). It’s still a step in the right direction, the direction of absolutely awesome invisibility suits and laser guns and women in tight, form fitting clothes. Well, 2 out of 3 at least.
Researchers at the University of California in Berkeley have created a material that bends visible light around nano-sized 3-dimensional objects, rendering them invisible. The material is artificially made and has properties smaller than the wavelength of light which allows for the unique effect.
An interesting point is how one professor chose to explain cloaking bigger objects like people.
In order to have the ‘Harry Potter’ effect, you just need to find the right materials for the visible wavelengths,” says Prof Hess, “and it’s absolutely thrilling to see we’re on the right track.
