is because it's covered with the darkest color on Earth.

that it captures at least 99.995% of incoming visible light.

But why is it covering a $2 million diamond?

and media outlets called it the darkest color in the world.

And that's thanks to an unprecedented collaboration

Her goal was to make a diamond disappear.

in reference to luxury and art and society.

He was working with a material called carbon nanotubes,

to boost the thermal and electrical properties

he was producing something even darker than Vantablack.

Strebe: Brian was looking into the optical properties

And so it kind of caused, really, from this art project,

Narrator: The new material, which Wardle has yet to name,

is 10 times blacker than any other color ever reported.

with the structure of those nanotubes themselves.

but you can actually grow carbon nanotubes.

will sprout out of those metallic particles,

Brian Wardle: You do it in the way we've done it here,

you get the recipe right, you can create forests.

These are very, very long aspect ratios of, like, a million.

Right, the length of the tube is, like, a million,

And that grows into what's called a forest.

When particles of light, called photons, enter it,

nearly all of them get trapped and then dissipate as heat.

In fact, Wardle's team followed the exact same procedure

to grow those nanotubes directly onto a diamond.

And that's pretty wild when you consider this:

just the different atomic letter structure,

makes them so extreme opposite in the phenomenology,

and/or look in more detail, at objects such as exoplanets.

Because even an absorption rate this high
