alchymista:

This material is the darkest known substance in existence, absorbing 99.9% of the light it comes into contact with. Made when carbon nanotubes are tacked on their ends and compressed together, microscopically the surface is rough and uneven, effectively breaking up the light and inhibiting its ability to reflect light. In certain arrangements, these carbon nanotubes can acts superconductors, which makes them even better at absorbing light.
And, of course, with extremes comes potential use, as scientists believe that this substance could be used to improve telescopes and more efficient solar collectors, because virtually no light is wasted.  (via)
