Vantablack... even the black bits are black

The Darth Vader of finishing materials, Vantablack is the darkest material ever made. If they're able to coat an entire room, how long will it be before someone uses it as a finishing coat for a speaker. Talk about speakers disappearing into a room!

  • To whom more was given more will be required.
    • Never go to a psychiatrist, adopt a straycat or dog. On the street they live only two years average.

Why not the SR-71 BlackHole5 as used by VMPS? looks suffice to damp cabinet resonances.
Seems VantaBlack action are in light not in sound or vibrations.

Well, they wouldn't disappear. They'd just look like a black shape sitting there. It'd be weird. Imagine a black 2 dimensional shape that is actually 3 dimensional. Hard to explain. Think of what a black cube would look like if you can't distinguish any edges or faces even as you walk around the cube looking at it.

What's interesting is that the material "absorbs" light. Thinking of light as energy, the material may have sound energy absorbing properties as well. Both types of energy are related, but I lack the scientific acumen to explain it properly.

It is the perfect material to use to coat the inside of telescope optical tube assemblies as well as eyepieces and digital cameras intended for astrophotography.
This is also the material to use to coat heat-sink assemblies.
It would be very useful to help manage heat build up problems in satellites and space craft. These can only be cooled via radiation, conduction and convective cooling are not possible.

Yes, quite right, we're only talking hypothetically about the visual aesthetic of the enclosure and the diminishing of the perceived three- dimensionality, not sound reproduction, at least not at this time.

yeah. but it's hell to keep clean, every speck of dust....

Seriously this micro carbon tech is going to change things big time. Soon carbon will start replacing silicon in our electronics, graphene and nanotubes in our speakers.

Thanks to Bill Gates we'll even have carbon in our condoms.
