There are many types of colors all over the world, but out of all the colors, black is considered very wretched, even if it is black cloth, but scientists have considered this color to be very important. According to science, black color provides excessive heat. This is the reason why people often wear black clothes during winter, because black color absorbs the heat of the sun and does not let it go out, due to which the body heat remains. Black color is considered as the dominant color among all colors, because it is prepared by blending of all colors. Although there are many such things in the world which are very black, but do you know which is the darkest substance in the world. No, no… So today we are going to tell you about such dark matter.

The darkest substance in the world is known as 'Ventablac'. It is so black that if it is shipped to some umber-place, then its surface starts to look flat. The reason for its blackness is that it absorbs 99.96 percent of the light. Ventablac was developed by Surrey Nanosystems, a UK-based nanotech company, in 2014. Only last year, the company has also introduced it as a spray. Now you must be thinking that it is some paint, then you are wrong. Ventablac is not a paint, but is made up of carbon nanotubes.

Actually, the thickness of each nanotube in Ventablac is equal to 20 nanometers i.e. 3500 times thinner than the thickness of a human hair. The light is stuck in the fine spaces between these nanotubes, due to which only the blackness is seen in Ventablac, except this. Only last year, with the help of this material, BMW made a car, which was considered to be the blackest car in the world.
