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,

Once you go black you’ll never come back.
Dummy, it was a YELLOW diamond - minority diamonds cant be racist, you’re obviously not sufficiently woke.
I believe the AJAX White Knight, of fifty years ago,could make it “Whiter than white!”
“Stronger than dirt! Stronger than dirt!”
nono....yellow diamond...
“a 16.78-carat natural yellow diamond”
So unable to be so...
Wonder how much more black it could be.
None ...none more black
Really ? Thought that was the part of Hillary Clinton where most folks have a heart.
Maybe we should open up betting on the over/under...

I always thought Joe Biden’s brain was faster than the Speed of Dark. Perhaps it’s full of carbon nanotubes?
Ah ... if only Ad Reinhardt were still alive.
The ultimate black lies deep beneath the earth in a long forgotten cave. It fills a fathomless void where no light has ever been known. I don’t want to talk about it any more.
The more it looks like a void, the blacker it is. Got it.
Or the spoof of a Work Order for the metalworking shop:
1. Pound to size.
2. File to fit.
3. Paint to hide.
The principle of conservation of energy. When a black body absorbs light the energy in the photons does not cease to exist. Loosely speaking, it is converted to random, disorganized mechanical energy, in other words, heat. Think of a black car on a hot day.
The heat is converted back to electromagnetic energy according to Stephan-Boltzman’s law.

Sunlight warms the surface of the earth (which does not absorb all wavelengths, much sunlight is reflected back into space), and air cools the surface of the earth, or rather, the surface of the earth warms the air.
The mechanisms that allow heat in the atmosphere to be radiated back into space are at the heart of the global warming debate.
black nanotubes matter
Hmmm... Could predict that this thread will go over 100...
Black threads mater!

Wow, I could have really used this when designing ECPRs (Electrically Calibrated Pyroelectric Radiometer)
This is a transfer standard for measuring optical power.
