Currently (the best known) the darkest material in the universe after your black holes or the heart of your former – so Vantablack could be described as the shortest. Vantablack is a material made with the aid of carbon nanotubes, namely vertically aligned carbon nanotubes having a width of one billionths of a meter or about 3 gold atoms. The “forest” of carbon nanotubes is “grown” in a laboratory on the surface of aluminum. Carbon nanotubes operate so that the light traps between vertically placed pipes, rejects around the tube as long as the energy of light does not spill and Vantablack does not absorb that light as heat energy. It is therefore one of its unique properties and it absorbs the heat very well.
It has been proven to absorb 99.965% of the visible light spectrum.
Just imagine a whimsical or short-term enthusiasm that would get you covered when you enter the room completely covered with Vantablack. They would feel as if they were floating in the universe but could not perceive the size, shape or depth of a person in the room, even though they could see it. They would be disoriented and surely they would want to come out of this room as soon as possible
In practical applications, it is used in telescopes to prevent unwanted light entering the telescope and infrared cameras, both on Earth and in the universe. It is also used in solar thermal power plants that use concentrated solar power.
It’s so black to absorb lasers and it’s a tadpole of reality, so in photos it looks like someone in Photoshop shone part of the picture in a total black.
Vantablack is also linked to controversy over property rights and names, but writing about it is left to scientifically-yellow portals. (We are neither a scientific nor a yellow prospective)
