A Dyson Sphere/Shield World (or "shell" as it appeared in the original paper by Freeman Dyson) is a hypothetical mega structure that was originally described as a system of orbiting solar power satellites meant to completely encompass a star and capture its entire energy output. Dyson speculated that such structures would be the logical consequence of the long-term survival of technological civilizations, and proposed that searching for evidence of the existence of such structures might lead to the detection of advanced intelligent extraterrestrial life. | A Dyson Sphere/Shield World (or "shell" as it appeared in the original paper by Freeman Dyson) is a hypothetical mega structure that was originally described as a system of orbiting solar power satellites meant to completely encompass a star and capture its entire energy output.

Since then, other variant designs involving building an artificial structure — or a series of structures — to encompass a star have been proposed in exploratory engineering or described in science fiction under the name Dyson Sphere. Most fictional depictions of a Dyson sphere describe a solid shell of matter enclosing a star, which is considered the least plausible variant of the idea. | Since then, other variant designs involving building an artificial structure — or a series of structures — to encompass a star have been proposed in exploratory engineering or described in science fiction under the name Dyson Sphere.
