Vantablack is a substance made of carbon nanotubes and is the blackest substance known, absorbing a maximum of 99.965% of radiation in the visible spectrum. It comprises a forest of vertical tubes which are "grown". When light strikes vantablack, instead of bouncing off, it becomes trapped and is continually deflected between the tubes before eventually becoming heat.
== Etymology ==
Its name comes from the term Vertically Aligned NanoTube Arrays.
== Development ==
Early development was carried out at the National Physical Laboratory (UK), although the term VANTA wasn't coined until som...
