Imagine something so dark that you can't see anything on its surface to the naked eye it would appear simply as a void like a deep black hole.That's what you'd see if you were looking at darkest manmade substance vantablack. created by surrey nanosystams (uk) and unveiled in jul 2014 vantbalck is so dark that the human eye cannot discen any shapes or its surface. it absorbs 99.96% of all light even types of light that fall outside the visible range such as ultraviolet and infrared as well as microwave radiation and radio waves. vantablck is make from carbon nanotubes a fast growing substance some 10,000 time thinner than the average human hair. We grow the tubes like a field if carbon grass eplanin ben jensen nanosytems chief technical officer. When light particles hit vanblack they bounce between th nanotubes which are spiced apart and are then absorbed. Or as ban puts it light goes in but it can't get back out . The word vanta refers to the structure of the substance it stands for vertically aligned carbon nanotube arrays. so far so -sci- fi- but how would you sue it well as light has virtually on impact on vantaback it could be vantback it could be be very useful in improving the sensitivity of astronomical cameras and infrared scanners. It could boost the sensitivity of telescopes so that they could see stars farther away than is currently possible. Its facility for absorbing light would also make it valuable for stealth military equipment.
