Vantablack; the Blackest Substance known

[Plenum]

Vantablack is a substance made of carbon nanotubes and is the blackest substance known, absorbing up to 99.965% of radiation in the visible spectrum.

The name comes from the term "Vertically Aligned NanoTube Alloys"

Vantablack is composed of a forest of vertical tubes which are "grown". When light strikes vantablack, instead of bouncing off, it becomes trapped and is continually deflected among the tubes, eventually becoming absorbed and dissipating into heat.

Vantablack was an improvement over previous similar substances developed at the time. Vantablack absorbs 99.965% of visible light. Also, this new material can be created at 400 °C (752 °F); NASA had developed a similar substance that could be grown at 750 °C (1,380 °F). Vantablack can be grown on materials that cannot withstand higher temperatures.

. . . Only my black-hearted love!

Isis asked: "... how much more black could this be?"

Answer: Class 1/NLM 11.0 on the Bortle Scale.

[Incidentally, love and kisses to Koch Entertainment and UMG, "one or more of whom" have (like the villainous, machinating rat-bastards they corporately are) blocked the 1966 original artist's video of this song. Ah, mais tellement pire pour ces scélérats de cœur noir. J'ai habilement vaincu leur intrigue profonde. Baise-toi, tu mécréants! Voilà!]

The actual blackest body in existence, I suspect, is the human heart gone awry, which is capable of being so abyssally dark that it would need to don shades when viewing the relative blinding-lightness of mere Vantablack.



https://www.surreynanosystems.com/vantablack  Vantablack S-VIS, the second-blackest black in the world, is a spray-on version of Vantablack proper. Think of the profit possibilities in providing S-VIS-treated clothing for the hipster/beatnik/goth/emo/Ninja/funeral-director et al. market, which currently has to make do with mere regular-old-fashioned-just-plain-black garb. People usually have to pay the big bucks for my investment tips, and here I'm giving one away! And it's sure-fire. Ah well, anything for Service and Duty to Humanity and brownie points toward achieving that coveted 51% STO-polarization.



Get some for yourself (be sure to make up some plausible-sounding phony corporate laboratory name, to sneak past the UK export laws, and swear on a stack of bibles that you won't misuse the stuff): https://www.surreynanosystems.com/vantab...le-request

Advice for a certain human tribal faction exhibiting extreme human-heart-gone-awry-ness:

I have heard about this stuff somewhere. Looks like a really cool toy but I would probably just spend my days starring into the abyss. Carbon nanotubes can be used for a very wide range of interesting stuff. You can create some pretty impressive structures using nanotubes. In theory it is a serious candidate for building a space elevator. I would love to see something like that happening soon.
