以后晚上出門,穿上這種材料制作的衣服,女朋友也可以在空中飛了

這是某處摘來的英文:
$ I# p5 s8 |: [0 EA British company says it has scored a breakthrough in the world's darkest material. Surrey NanoSystems describes its development as not just a black material but super-black. They are calling it Vantablack, and they are singling out its ability to be applied to lightweight, temperature-sensitive structures such as aluminum, absorbing 99.96% of incident radiation; that is, they said, believed to be the highest ever recorded. This coating is made of carbon nanotubes – "each 10,000 times thinner than a human hair," wrote Ian Johnston in The Independent on Sunday. It's not what you see; it's what you don't see. If fact, you see nothing, period. "It is so dark that the human eye cannot understand what it is seeing," wrote Johnston. "Shapes and contours are lost, leaving nothing but an apparent abyss.")

黑體是熱力學概念,翻譯成光學概念是譯者的無知,”absorbing 99.96% of incident radiation“就變成了可見光,不知怎么譯的。
