You might think you already know black – even super-black Vantablack, previously the blackest material known to science – but researchers just came up with a material that takes black to a new level of blackness.
The new, as-yet-unnamed ultra-black material is made from vertically aligned carbon nanotubes (CNTs), microscopic carbon strings that are a little like a fuzzy forest of tiny trees, according to the team behind the project.
And here's the rub – this CNT material can absorb more than 99.995 percent of incoming light, beating the 99.96 percent that Vantablack is able to absorb.
MIT artist-in-residence Diemut Strebe has worked with the researchers to coat a 16.78-carat natural yellow diamond, estimated to be worth $2 million, in the ultrablack material.
What should be a bright, sparkling, highly reflective gem ends up a lightless void.
"Because of the extremely high light absorptive qualities of the CNTs, any object, in this case a large diamond coated with CNTs, becomes a kind of black hole absent of shadows,

Blacker that a black cat it a coal bin a mile inside a cave on a moonless night.
50 Shades of Black...
I’ve never seen fifty at once?
But near Cicero Ave and the Eisenhower Expressway, on payday at the old Hawthorne Works, many shades of black available for a fee.
That’s racist.
Don’t imagine there’s much of a market for that diamond now.
And all this time I thought a radiometer was a glass bulb with the B/W spinning paddles!
Neat stuff!
Soon, a CNT Black car!

How would that do vs. a cop’s radar?
I didnt read the article yet. Whats it called... Yaphettkottoite? Maybe something ironic like Dolezalium or Seankingium?
Is Vantablack the opposite of Vanna White?
I apparently didnt read your post, either...
Guess it’s up to me to add the obligatory Spinal Tap reference...
Nigel Tufnel: There’s something about this that’s so black, it’s like how much more black could this be? And the answer is none. None more black.
Black is Black!
Is Vantablack the opposite of Vanna White?
VERY NICE!!!
Two thumbs up!!!
What would it be like standing in a room covered in this stuff with a small 40 watt bulb hanging in the middle...

Interesting thought experiment. I imagine one would see only the bulb glowing in an apparent void. Would probably be a bit disorienting.
Yeah, just like Donald Duck’s uncle, Gyro Gearloose, inventor of the Gloom light.
Why a diamond? One could dip a diamond in liquid asphalt and there’d be no reflections.
Ninjas wonder too.
100% light absorption would be invisible?
Sure, it could cast a shadow and you would not be able to see though it, but I can see some great military applications.
I thought the new name for black was “colored” as in people of color.
If the atmosphere did not retain heat at night we would all freeze to death at sunset. Not to mention fry during the day.
