The basic idea is that a structure is constructed around a star that converts, stores, or otherwise utilizes the star’s radiant energy. These facilities are postulated as the most likely, necessary, and economical way of addressing the colossal energy needs of both future human civilization and, possibly, advanced alien civilizations elsewhere in the cosmos.   Who theorized them? And when?   The Dyson sphere concept is named after physicist Freeman Dyson (1923-2020) who, in 1960, discussed the idea in a short scientific paper...
