Also a lot of practical stuff.
This substance has many potential applications, including preventing stray light from entering telescopes, and improving the performance of infrared cameras both on Earth and in space, Ben Jensen, Chief Technology Officer, Surrey NanoSystems, has explained: "For example, it reduces stray-light, improving the ability of sensitive telescopes to see the faintest stars... Its ultra-low reflectance improves the sensitivity of terrestrial, space and air-borne instrumentation."
Vantablack may also increase the absorption of heat in materials used in concentrated solar power technology, as well as military applications such as thermal camouflage. The emissivity of Vantablack and scalability support a wide range of applications.
The material is being used creatively by artist Anish Kapoor who said, "It's effectively like a paint... Imagine a space that's so dark that as you walk in you lose all sense of where you are, what you are, and especially all sense of time. The color was exclusively licensed to Kapoor's studio for artistic use, outraging some other artists who would be unable to use it. However, the manufacturer has explained that Vantablack is also subject to export controls by the UK, and due to its temperature and physical requirements is not practical for use in many types of art.
I have an idea: get a ball. A metal ball. Put it atop a magnetic surface. Coat it in vantablack paint.
Now you have what looks like a 2D hole in reality floating in midair.
Get a cloak. Paint it vantablack. Now you look like the Grim Reaper.
Paint your car vantablack. Watch as it looks like some ghostly vehicle floats down the street.
