Invisible Lex!

It used to be I had to wait for Stage 9 to kick in, but thankfully that may no longer be necessary:

Black is getting blacker.**

Researchers in New York reported this month that they have created a paper-thin material that absorbs 99.955 percent of the light that hits it, making it by far the darkest substance ever made — about 30 times as dark as the government’s current standard for blackest black.

The material, made of hollow fibers, is a Roach Motel for photons — light checks in, but it never checks out. By voraciously sucking up all surrounding illumination, it can give those who gaze on it a dizzying sensation of nothingness.

But scientists are not satisfied. Using other new materials, some are trying to manufacture rudimentary Harry Potter-like cloaks that make objects inside of them literally invisible under the right conditions — the pinnacle of stealthy technology…

Known as transformation optics, the phenomenon compels some wavelengths of light to flow around an object like water around a stone. As a result, things behind the object become visible while the object itself disappears from view.

If I had only had that piece of gear at last year’s MilBlog Conference.

Still: Groovy.
