Dyson Sphere May Be Detectable Through Waste Heat from a Star
In 1960, physicist Freeman Dyson proposed finding extraterrestrial civilizations through infrared radiation. A civilization using most of a star's energy could build many energy-collecting stations orbiting it. Visible light would dim, but the absorbed energy must ultimately escape as heat.
