World's darkest material is now even darker

Known as Vantablack, the extremely dark material was invented by a team of British researchers in 2014.
The material, which is so dark that looking at it is like staring in to an abyss of infinite nothingness, has now been made even darker thanks to the continued efforts of Surrey NanoSystems, a company that specializes in the production of nanomaterials at low temperatures.

The original incarnation of Vantablack was dark enough to absorb all but 0.035 percent of visible light meaning that to the naked eye it barely registered as a physical material at all.

The new version of the material however is now so completely and utterly dark that there is no spectrometer on Earth that can accurately measure exactly how much light it absorbs.

Originally developed to enhance the performance of sensitive electro-optical imaging systems in satellites, Vantablack is made up of millions of tiny carbon nanotubes which are each 3,500 times smaller than the diameter of a human hair.

Light hitting the material enters in to the gaps between the nanotubes and bounces back and forth between them, unable to escape.

"Even running a high power laser pointer across it barely reflects anything back to the viewer," the team explained. "We have never before made a material so 'black' that it can't be picked up on our spectrometers in the infrared."

I wonder how a room would 'feel' if I was standing in it, and the walls were lined with this vantablack. I wonder if it would feel 'eerie'. That's the feel I'm imagining. I wonder if it would feel like you're standing in a different 'place' that doesn't 'feel' like Earth. I know the human mind is capable of 'playing tricks' on itself. I'm just imagining another mind hack. I like calling things you do to 'play tricks on yourself' as a 'mind hack'. Just sounds cool. LoL!!

Tests conducted in the fifties in total darkness the subjects were only able to endure total blackness for less than 48 hours... [More]

If you form it into a circle and lay it on the road it becomes a coyote trap.

Create an android completely coated with Vantablack, that would be awesome for some Sci-Fi movie.

I want my walls lined with a wallpaper made out of this. Hopefully they find a way to make this semi affordable for commercial sale.

Looking at the videos, the thing's appearance remind me of bad photoshop jobs. It's like someone just cut a form and we see the black background layer. It must be even more weird in real life.

Kudos to the English. I wonder how much this material is priced per square foot.
