To what extent can a thing be black? Vantablack is the darkest substance ever made by humans. Surrey Nanosystems, based on carbon nanotube materials, can absorb 99.965% of visible light, which is almost the same as a black hole. Its name is just an abbreviation, the full name is Vertically Aligned NanoTube Arrays, which means "vertical array of nanotubes" (scientists sometimes are not romantic). Nowadays, this material has finally left the laboratory, and for the first time, it has completed a product from the perspective of consumers. It was sprayed on the Lynx Space Cup to make the world's darkest cup. To what extent is black? Someone said after reading: "My eyes can't focus. It's too dark, I can't see any details at all, it's almost like a black hole, sucking away all the light." This kind of description is very appropriate, because people want to see a thing, they have to reflect light into the eyes, and it will only leave you 0.035% of visible light, naturally it will be caught. Don't think it's easy to spray this material. It took more than 400 hours for the researchers to get it in four months. Of course, the cup is too big to use, Vantablack can also be used to correct the space telescope to observe the deepest and oldest objects in the universe.
