The "darkest ever" substance known to science has been made in a US laboratory.
The material was created from carbon nanotubes - sheets of carbon just one atom thick rolled up into cylinders.
Researchers say it is the closest thing yet to the ideal
black material, which absorbs light perfectly at all angles and over
all wavelengths.
The discovery is expected to have applications in the fields of electronics and solar energy.
An ideal black object absorbs all the colours of light
and reflects none of them. In theory, it should be possible to make
something that approaches the "perfect absorber".
The application will be to things like more efficient
solar cells, more efficient solar panels and any application where you
need to harvest light.
