An almost perfectly black and almost perfectly anechoic chamber with almost zero external sound. Peaceful or nightmarish?
The last I heard about anechoic chambers, most people can't stay in them for very long, apparently it's incredibly unsettling after a while.
It's really not that bad. Some people find it unsettling, but many find it kind of relaxing. Derek from Veritasium has a good video on it for the interested.

#83I 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.
It is far easier to block light than absorb it. You can experience that type of absolute darkness with a $10 eye-mask (The new ones that look like tiny bras) from your airport. Your ears will orient you if you let them.

Check out the Vantablack BMW X6 ( https://www.bmw.com/en/design/the-bmw-X6-vantablack-car.html )
I'm curious... would that car get incredibly hot parked in the sun?
Maybe for a bit, then the paint would melt off. It's not rated for getting wet... or hot.

It would just be....completely dark? I had this experience when working at a mine at one point, and if you went down one of the tunnels and switched off your headlamp.....it was absolute darkness. Like, we think that our bedroom at night is "completely dark" - but that's usually not true, that's always some source of light, after some adjustment you can see at least faintly. In an underground corridor without any lig…
I've actually worked on blocking all light in one bedroom. This is a great thing when one must sleep during the day.
The one window is thoroughly covered using well fit light blocking material. During daylight there is a very small amount of light the gets in under a door. At night it is utterly black. You may wait as long as you wish for your eyes to adjust; you cannot see your hand in front of your face. Nothing. Activating a smart phone becomes painful.

#86I am concerned with this subject on a daily basis and this is the most civilized and educated discussion I saw until now.
Refreshing, really. Thank you

#87I feel like they missed the opportunity to name it None More Black [1]. [1] https://www.youtube.com/watch?v=zSkGtW-fQ3s
I'd like one of these to be named fuligin as in The Shadow of the Torturer.
We developed an ultrablack fabric and totally missed that opportunity.
But then people pointed me towards the book when we did an Iama on reddit and what an excellent read!

#88Does anyone know how stable these coatings are in real life? How easy is it to dust off or wet clean one of those super black coatings? How well would it take daily touching?

Pilots flying in "hard" instrument conditions also experience this. You can see the interior of the airplane, but everywhere you look outside is exactly the same shade of grey/black/white, and there's no usable data from your sense about the position of the airplane relative to the earth. Passengers who think about this might intellectually get it, but it's quite a different experience when you're looking out the fro…
When night diving, you can at least blow air into your hand then feel which way the bubbles travel. eg "which way is up?"

These things have applications for stealth aircraft as they often absorb radar as well as visible light. But even for visible light, if you're looking at something painted vantablack in broad daylight, you only see a silhouette--much like WWI "Dazzle" camouflage, it's very difficult for the brain to process what you're looking at.
That's very interesting, I was thinking about stealth bombers. Do you think it would have applications in say, military uniforms? I wonder how it compares to digital camo, mirror based camo, etc in regards to detection.

During the first gulf war they gave us some jackets that absorbed the wavelengths the night-vision goggles could see so you'd just see a human shaped void which kind of stands out a lot more than a regular person -- not the best of plans.
