Dyson Sphere
Version 1.0.0 · Updated 2026-07-28
CORE DEFINITION
The Dyson Sphere is a hypothetical giant spherical structure surrounding a parent star, conceived by Freeman Dyson, which can capture most or all of the star's energy output. Dyson believed that a Dyson Sphere is an inevitable necessity for a long-surviving technological civilization due to growing energy demands, and that searching for evidence of its existence could lead to the discovery of advanced and intelligent extraterrestrial life. Different types of Dyson Spheres and their energy collection capabilities would correspond to technological advancements on the Kardashev scale. Since the concept was proposed, many artificial structures surrounding stars in science fiction works have been dubbed 'Dyson Spheres'. Subsequent speculations suggest that Dyson Spheres would not only contain solar power stations but also human colonies and industrial bases.

Anchor fast decisions
Physicist Freeman Dyson envisioned that a Type II civilization, to capture nearly all of a star's energy, could use a megastructure (a shell or a swarm of satellites) to envelop the star and collect its radiation. On the Kardashev scale, this corresponds to a civilization capable of utilizing all the energy of a star. It concretizes the idea that 'energy is a bottleneck for civilization' into a device that can capture the entire output of a star.
