Since the volume of a spherical object (such as the event horizon of a non-rotating black hole) is directly proportional to the cube of the radius, the density of a black hole is inversely proportional to the square of the mass, and thus higher mass black holes have lower average density.@needweed: Gazul este tot materie dar sub alta forma de agregare. Si poate avea densitate foarte mare. Practic, este vorba de plasma care, la presiuni foarte mari, poate deveni chiar lichid.
