I think it would be cool to walk into a room painted entirely with this material. I bet it would be so disorienting that people would fall down and get vertigo. So weird.

Yeah, I'd love to try that out. Imagine waking up in a room painted with that.

Would the human eye see the difference between this and Vantablack? Even though it's ten times darker I feel like the returns would get smaller and smaller.

Also, what would 100% light absorption look like?

> Strebe has coated a $2 million (£1.6 million) 16.78-carat natural yellow diamond in the material Wouldn't it have been smarter to, say, make a glass replica, coat that, and pocket the $2 million diamond?

Archimedes solved figuring out for density, there are also other non-destructive tests.

Tests only work if someone is actually going to do them :)

I love carbon and carbon materials. Here's an amazing clip showing Vantablack. It's so dark it looks like an optical illusion: https://www.youtube.com/watch?v=fg2x0L4YAuU And apparently this stuff is blacker!

I just watched that and at the end they state that you can't buy it because it's subject to UK export controls. The Vantablack website confirms this:

> In order to comply with UK export control regulations we are required to verify the identity and credentials of potential clients and the nature of their proposed use of Vantablack. Only verified companies, research facilities and educational establishments can order a sample of Vantablack. The coating is not available to private individuals at this time and we can’t accept orders from private email addresses.

Assuming it isn't because of it's chemical compositions, why would this be controlled?

Earlier quoted context omitted.

It's a piece of art - you could reduce the cost in many ways but it's subjective whether you'd be achieving the same thing as it doesn't have any intrinsic value except for how people appreciate it.

I know. My "joke" is that the artist could have used it as a scheme to steal a diamond. Not necessarily implying any foul play though.

I mean, it could be the case that the real diamond isn't there at all, and is back safely in some vault.

How about an anechoic chamber (https://www.youtube.com/watch?v=mXVGIb3bzHI) painted in this stuff?

An almost perfectly black and almost perfectly anechoic chamber with almost zero external sound.

Peaceful or nightmarish?

Wouldn’t a pitch black room achieve the same effect with much less cost/effort? As far as I know the idea of these compounds is to absorb light, but if you get rid of light to begin with then you don’t need them?

Both.
