Black means no light reflection. Since nothing in the world is perfect, there is no "real" black thing. Scientists at Rice University in Houston and Rensselaer Polytechnic Institute in Troy, N.Y. developed a material that is near perfect, rerlecting only 0.045% of incident light.
The rule is simple, the less light you reflect, the darker you are.
With carbon nanotubes of random length and arrangement standing on the surface, light reflection is minimized.
The use? Light-detecting sensors. How? I don't know.
