Hope it helps ✌

A British nanotech company has created what it says is the world's darkest material. It is so dark the human eye can't discern its shape and form, creating what has been called a black hole. Vantablack, made out of carbon nanotubes, is designed by Surrey NanoSystems and absorbs 99.96% of all light that hits it.
