thebeakerblog: “It’s like, how much more black could this be? and the answer is none. None more black.”So said Nigel Tufnel in Spinal Tap, but it turns out that album cover actually could have been a lot darker thanks to a product called “Vantablack.”According to the New York Times:Vantablack, for Vertically Aligned NanoTube Array, is made by “growing” carbon nanotubes on a metal surface. (A nanotube is a billionth of a meter thick, or about the width of three gold atoms.) Light is trapped between the tubes and bounces around until it’s absorbed, so almost no light gets out.The material is lightweight and can be applied to structures like aluminum. It absorbs 99.6% of light, which its developer, Surrey NanonSystems, says is “believed to be the highest ever recorded.”New York Times: Gazing Into the Void: What You Can Do With Vantablack, the Darkest Material Ever Made(Image Credit: Surrey NanoSystems) -- source link
