Black color is considered to be the predominant color among all colours, in childhood used to study in science class that black color absorbs all colors inside itself. Because of this, no color can be seen in it. But do you know which is the darkest substance in the world?
darkest substance in the world
Black color is considered very wretched in itself, even if it is a black colored cloth, but this color is very important for scientists. It is said that it is advisable to wear black clothes during winters, because black color absorbs the heat of the sun and does not let it out, due to which heat remains in the body.
Black color is considered to be the predominant color among all colours, in childhood used to study in science class that black color absorbs all colors inside itself. Because of this, no color can be seen in it. But do you know which is the darkest substance in the world? If not, then let’s know about it today.
We are talking about ‘Ventablack’ which is known as the darkest substance in the world. It is so black that if it is dumped on any rough place, its surface becomes completely flat.
Ventablack has the power to absorb light. It absorbs 99.96 percent of the light, which is so much that even if a very thin layer made of this material is applied somewhere, there will be darkness and it will be impossible to see anything.
The thickness of Vantablack’s nanotubes is similar to 20 nanometers, that is, it is thinner than a hair. The length of the Vantablack is 14 to 50 microns, that is, a small space of 1 square centimeter can accommodate 1 billion nanotubes. It was made in the year 2014 by the UK nanotech company Surrey Nanosystems. It is so dark that it is enough to spread darkness even in bright light.
The thickness of each nanotube in VentaBlack is 20 nanometers, which is 3500 times thinner than the thickness of a human hair. Light gets trapped in the fine spaces between these nanotubes, due to which only and only blackness is visible in VentaBlack, nothing else. Only last year, with the help of this substance, BMW made a car, which was considered the blackest car in the world.
