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,

A statement which is not in anyway in conflict with my post. The global warming debate is about the mean equilibrium temperature, and the mechanism that maintain it.
That room would be perfect for putting a Holodeck in.
Black is Black!
I want my baby back!
Or as the Southern boys used to sing back in 1967,..
Black is Black..
I want my darkies back...
Black cars look better in the shade.
The most pleasant swim I ever had in a private pool was in a very elite neighborhood with old estates. This house had a pool painted black. No electric heating bill, and it was a very warm, but not hot, environment.
Can they send me a couple material samples? We’re looking to recover a black vinyl recliner and want to insure we get the darkest shade possible.
“Yellow” must mean it was an Asian Diamond that put on Blackface.
Asian is then new white.
Still racist.
It’s African American!!!
>What would it be like standing in a room covered in this stuff with a small 40 watt bulb hanging in the middle...
Methinks one would not only see the light bulb along with your own skin and clothing in a black void, unless you were dressed in black clothes and painted with carbon nano-tubes in which case you would effectively be invisible to anybody else in the room at the same time.
The trivial destruction of a $2 million diamond illustrates that colleges have way too much money.
It took me a couple of minutes to notice that the coated diamond surface is actually blacker than the background black. I had to tilt my LED screen at just the right angle to see the outline of the black diamond against the less black background.
It doesn’t count if your friends can afford it.
In short no matter how exotic, how cutting edge, how completely incomprehensibly Hi Tech, the material is, it always used first in Golf Club.
