The Boundary of Blackness

It's not as racist as it sounds. Some researchers have created what is supposed to be the blackest substance ever made, as in it absorbs 99.9 percent of the light that hits it. It's a collection of carbon nanotubes stacked next to each other. There is a picture of it in the link (picture #3). It's blacker than the blackness standard currently used by N.I.S.T. The theory is that this might be useful in solar energy production or stealth applications. Cool stuff.

Franny's not impressed. She says she made one of these years ago. Of course you use nanotubes. It's the teeniness that does it. The light can't get through. 'Cuz the teeniness. And the carbon. I love pregnant scientists.
