# Dyson Sphere

A Topical Guide entry on the Dyson Sphere—Freeman Dyson's hypothetical megastructure that captures a star's energy output, explored in Mormon transhumanist context as a vision of godlike power.

A Dyson sphere is a hypothetical megastructure named after Freeman Dyson who explored the concept in his 1960 paper “Search for Artificial Stellar Sources of Infrared Radiation.” This megastructure would hypothetically be built to surround a star to harness large amounts of its energy. Such a structure could hypothetically be used by advanced societies whose energy needs outstrip what could be obtained at a planetary level.
