Captive Light Dream
Light can slow down and remain, at least in theory. But how? British physicist Ortwin Hess has discovered that it can be done with metamaterials. These materials present a negative refractive index, the rays of light tilt with an angle when passing from air to water and deviate with being in a metamaterial deviate with an opposite angle. Hess has made calculations to find out what happens to light in a three-material system that has a metamaterial interspersed. The result is that the system slows down the light and also makes it depending on the thickness of the entire system. From a thickness, the light would be completely inside, yes, physically separating the rays of different colors. Somehow it would catch the rainbow within a special material. This material does not exist, but is believed to be in the process of existing.
