Like me, you may have thought black is black and as dark as it gets. However, courtesy of carbon nanotubes (CNTs), individuals are creating blacker and blacker, even blackest versions of black. A quick Google or YouTube search yields all sorts of interesting results from BMWs painted in Vantablack, to the “blackest little black dress.”
In practice, CNTs are materials that can be vertically aligned to capture light in the 99.9XX percent range and produce blacker versions of the blackest black. CNTs are microscopic filaments of carbon that can be grown on surfaces for various uses.
