Blackest Material Ever Created

Scientists from Surrey NanoSystems have created Vantablack, the blackest material ever made, from carbon nanotubes. The material has an albedo value (reflecting power) of only 0.035% according to total hemispherical reflectance measurements. This means that 99.965% of all incident will be absorbed by the material. For reference, fresh asphalt has an albedo of 4%.

When a laser pointer and white light are scanned over a Vantablack-coated surface, the light appears to completely disappear. A three-dimensional object coated in Vantablack would appear two-dimensional because so little light is reflected off its surface. This severely limits our ability to sense the third-dimension (depth) of the object.

Um objeto em uma órbita elíptica se move mais rápido, uma vez que se aproxima do corpo do pai, então fica mais lento em proporção a distancia percorrida (Segunda Lei de Kepler).
