Scientists invent world's blackest material

Known as Vantablack, the mysterious material is so dark that it's like looking in to a black hole.
Developed by UK-based company Surrey NanoSystems, the ingenious invention has set a new world record by absorbing all but 0.035% of the visible light that hits it.

Constructed from carbon nanotubes each with a width 10,000 times smaller than that of a human hair, the material appears so black to the human eye that its almost impossible to make out any folds, creases or other physical features.

"Many people think black is the absence of light," said Prof Stephen Westland of Leeds University. "I totally disagree with that. Unless you are looking at a black hole, nobody has actually seen something which has no light. These new materials, they are pretty much as black as we can get, almost as close to a black hole as we could imagine."

Vantablack has been designed for use in telescopes, astronomical cameras and infrared scanners, but if you did create a dress out of it then the person wearing it would most likely appear as little more than a disembodied head and limbs floating mysteriously around a dress-shaped hole.

Aborbs light.... Good concept for efficient solar panels, however cost if implementing such expensive nanotechnology in the present doesnt weigh out the benefits.... Large scale mass production... Obstructions by major energy producers... Installations....... This being said... That just one of the alternative ways we can use it..... Maybe countless others

Reminds me of a scene in 'The Restaurant at the End of the Universe' by Douglas Adams where I think it's Arthur Dent is looking at a space ship that is so black he can't keep looking at it, his eyes just roll off it. I think that's how it went.

Would I be correct in assuming that because this material is so good at absorbing certain wavelengths of energy, it probably also would get quite hot when exposed to sunlight? Most dark materials do, but this might get somewhat hotter.

i like, i like. i wonder if it would be more slimming, for those carrying too much flubber?

The secret formula: 1 part soul of Nazi camp guard, 1 part heart of corrupt politician, 1 part madness of a communist dictator, 1 part lies of a White House Press Secretary, 1 part Satan's laughter. For good measure add one part sarcasm of UM poster. Very black indeed.

Actually that might be counter intuitive, as the night isn't anywhere close to pure black, so you'd have a bunch of man shaped black objects that would stand out even if the only light available was starlight. Also, black object absorb more heat, and this would be a problem on the modern battlefield with it range of IR and UV scopes. Generally the best camouflage has been found to not so much as blend in with a background, but to break up the outline of an object into something unrecognizable.
