Pressureless dust

A simplified cosmology matter icon depicted as a loose cloud or rounded cluster of many tiny neutral gray-brown particles. The particles are small matte circular specks or simple spherical grains, evenly and sparsely scattered, mostly uniform and featureless with slight size variation allowed. They should appear dry, compact, inert, and non-clumped, with no gas swirls, filaments, haze, glow, liquid appearance, pressure effects, or motion trails. The overall look is abstract, schematic, and suitable for representing idealized pressureless nonrelativistic cosmological dust. Use a flat schematic vector style with minimal shading and low detail.
