Dyson Swarm Civilizations

Dyson swarm civilizations are one of the most influential and comparatively plausible megastructure models in advanced alien-civilization theory: societies that do not build a single rigid shell around a star, but instead operate immense swarms of orbiting collectors, habitats, and industrial platforms. The concept sits at the center of Type II civilization discussion, Dysonian SETI, and modern ideas about stellar-scale infrastructure.
