Dyson spheres are theoretical constructs that harvest the entire energy output of a given star by completely enclosing it. They are named after physicist Freeman Dyson, who proposed the concept in 1960. A precursor to the concept of Dyson spheres was featured in the 1937 novel Star Maker by Olaf Stapledon. Fictional Dyson spheres are typically solid structures forming a continuous shell around the star in question, although Dyson himself considered that prospect mechanically implausible and instead proposed multiple separate objects independently orbiting the star. It is a type of Big Dumb Object.
