Now you see it, now you don't: cloaking device is not just sci-fi

The cloaking device relies on recently discovered materials used to make superlenses that make light behave in a highly unusual way. Instead of having a positive refractive index - the property which makes light bend as it passes through a prism or water - the materials have a negative refractive index, which effectively makes light travel backwards. It's light, but not as we know it.

This really does sound like some form of "cloaking" to me. Either that or we're "Flatlanders" and the faceless woman was a visitor from a higher dimension.

Fascinating stuff. I'm glad you drop by!
