Sphereworld, Dyson Sphere

- Also see: Inheritors who inhabit an Ancients built incomplete Dyson Sphere.
- See also: Dyson Sphere
Description (Specifications)
Using incredibly strong materials similar to those in a ringworld, and adding gravity generators where necessary for strength and comfort, a spherical shell could be built to completely enclose a star.
- Such a shell would then trap all stellar radiation for use by the civilization. With a radius of 149 million kilometers (about 93 million miles), the internal surface area would equal about one billion planets the size of Terra.
Sphereworld UWP
Sphereworlds are beyond TL 27 manufacturing capability.
- "Small" sphereworlds use world and gas giant size codes. "Dyson" sphereworlds use a size code of 'Y', indicating a stellar-scale construct. They all have the comment code 'Ax'. Due to TL skew, most UWPs with a size code Y and comment code Ax will be ringworlds, but sphereworlds also inhabit this space. Therefore, additional notes are typically expected.
History & Background (Dossier)
First postulated by Terran scientist Freeman Dyson prior to contact with the Vilani.
