“Vantablack” is a unique substance consisting from carbon nanotubes. In 2014, specialists from the British Surrey Nanosystems managed to get this amazing the blackest material on our planet.
When a person looks at him, our brain is not able to understand what is in front of him, and perceives “Vantablack” not as flat surface, but like an absolutely black hole in space.
Until recently, a miracle substance absorbed approximately 99.965% Radiation incident on it: radio waves, microwaves and visible Sveta. The video below shows a laser beam, aimed at this material. The light point is clearly visible on laboratory bench, however, when the laser hits the Vantablack, photons are lost between carbon nanotubes, practically no reflecting back and seeing the radiation is simply impossible.
Last week, employees at Surrey Nanosystems stated that they were able to make their material even more black. However, it is impossible to determine how much exactly, since even the most modern and sensitive spectrometers cannot do measuring the amount of light reflected from this substance. Is known only that this value is more than 99.965%, but less than 100%, since the receipt of material with a 100% absorption of radiation is still physically impossible. At least, so it is customary to consider in the scientific community.

Where can I use the blackest material
You probably already wondered: is it possible to find “Vantablack” any use? The answer is “definitely yes”, and in many spheres. For example, in the military industry, material absorbing almost all the light falling on it, maybe used to create the so-called “temperature camouflage “doing reconnaissance or combat flying The technique is invisible to locators that respond to heat. However, Britons refuse to answer any questions regarding military application of their development.
But they eagerly say that “Vantablack” will become indispensable in ultra-sensitive optical electronics, where even weak reflected light can greatly distort the useful signal or even lead to loss of device performance. To similar technology, for example, include powerful telescopes designed to observations of distant dim stars and black holes.
In addition, the famous British-Indian sculptor Anish Kapoor recently acquired exclusive rights to use “Vantablack” in art. One can only guess exactly how the artist will use the blackest material in the world in his work and what will be the reaction of the public to such a composition. Is it really new “black square”, only now in sculpture? ..
