Strebe had actually the scientists coat a diamond worth an estimated $2 million with the new material.

You are watching: What color is darker than black

Following is a transcript that the video.

Narrator: think it or not, this is a diamond. And the reason you can"t watch it is since it"s covered with the darkest shade on Earth. In fact, this material is so dark that it records at least 99.995% of incoming visible light. Yet why is it covering a $2 million diamond? and also how was it made in the very first place?

Narrator: You might remember this color, Vantablack. It to be unveiled in 2014, and media outlets referred to as it the darkest shade in the world. Yet this shade here? It"s no Vantablack. It"s also blacker. And also that"s thanks to an extraordinary collaboration between science and art. It every traces earlier to this artist, Diemut Strebe. In 2014, she set out top top a mission to discover the blackest black. Her goal was to do a diamond disappear.

Diemut Strebe: This project explores just how values connect to concepts and also objects in recommendation to luxury and art and also society.

Narrator: Meanwhile, a scientist named Brian Wardle to be on a totally different mission. He was working v a material referred to as carbon nanotubes, the exact same stuff offered to make Vantablack, though he was utilizing them to an increase the thermal and electrical nature of materials like aluminum. But tiny did Wardle know, that was creating something also darker 보다 Vantablack.

Strebe: Brian to be looking right into the optical properties of CNTs only due to the fact that of the arts project. And so it kind of caused, really, indigenous this art project, the research study to discover the blackest black.

Narrator: The brand-new material, i beg your pardon Wardle has yet come name, is 10 time blacker than any type of other shade ever reported. And that likely has to do with the framework of those nanotubes themselves. In this case, Wardle and his team thrived them on height of aluminum. Yeah. They may not be alive, however you have the right to actually thrive carbon nanotubes. First, friend cover a product with microscopic metal particles. Then you roasted it at high temperatures, in the presence of a hydrocarbon gas. And also that"s basically it. Carbon nanotubes will certainly sprout the end of those metallic particles, choose plants native seeds.

Brian Wardle: You execute it in the method we"ve excellent it here, you gain the cooking recipes right, you can create forests. These are very, very long aspect ratios of, like, a million. Right, the size of the tube is, like, a million, relative to the diameter. And also that grows into what"s referred to as a forest.

Narrator: the nanotube forest is the key to developing this black color color. Once particles of light, dubbed photons, go into it, nearly all of them obtain trapped and also then dissipate together heat. That"s why as soon as you look in ~ this black, friend see, well, certain nothing. No shadows, no ridges, simply black. And also that made the perfect because that Strebe"s diamond-vanishing project. In fact, Wardle"s team complied with the exact same procedure to flourish those nanotubes straight onto a diamond. And that"s pretty wild as soon as you think about this:

Strebe: Both is made of carbon. It"s the very same element, just the different atomic letter structure, renders them so too much opposite in the phenomenology, in their appearance.

Narrator: and also as it transforms out, this material isn"t just useful for multimillion-dollar arts projects. Scientists can also use it to reduce the glare in optical sensors, such as for telescopes that explore far-off objects in space.

Wardle: girlfriend know, if you have actually a product that can absorb the stray starlight, then you have the right to look further, and/or look in much more detail, at objects such as exoplanets.

Narrator: yet here"s the thing. As cool together this color is, it most likely won"t be the darkest for long. Because even an absorption rate this high tho leaves part room for improvement. So save your eyes peeled because that the next shade that you can"t see.
