Dyson Sphere

A Dyson Sphere is a hypothetical structure that an advanced civilization might build around a star to capture its energy output. Proposed by physicist Freeman Dyson in 1960, it could be a solid shell or a swarm of satellites that harness solar energy far more efficiently than Earth does. The idea reflects the search for extraterrestrial intelligence and our understanding of energy needs for future civilizations. Essentially, it represents a method of maximizing energy use on a cosmic scale, allowing for the potential growth and sustainability of advanced societies.
