Black matter is found universally, especially in the amorphous state.
All the black matter known to date, from the lithosphere and biosphere to the cosmos, generally has the same chemical and physical properties. The physical properties of black particles, and some of the chemical ones too, do not depend on the structure and nature of the melanogen. The atoms are arranged in hexagons or pentagons, which are assembled in sandwiches in layers 3.4 apart, like graphite in the open form, or giant fullerenes in the closed form. From many viewpoints the melanins resemble activated charcoal in their chemical-physical behaviour. Radioastronomy has shown there are organic molecules in the black dust clouds in the Milky Way.
