Blackest is the new black: Scientists have developed a material so dark that you can't see it...
Found on The Independent on Sunday, 13 July 2014
A British company has produced a "strange, alien" material so black that it absorbs all but 0.035 per cent of visual light, setting a new world record.
It also has "virtually undetectable levels of outgassing and particle fallout", which can contaminate the most sensitive imaging systems. The material conducts heat seven and a half times more effectively than copper and has 10 times the tensile strength of steel.
Sounds like a fun toy that can be used in many different cases.
