Ring World

An incredibly strong band could be set rotating about a central star, making a Ringworld that uses centrifugal force to provide a simulation of gravity.

• Please see Planetoid, Rosette, Sphereworld for information about related technologies.

Description (Specifications)

A ringworld with a radius of 148 million km (93 million miles) and a width of 1.6 million km (1 million miles) would have a usable surface area equal to three million planets the size of Terra (Solomani Rim 1827).

Ringworld UWP

Ringworlds are buildable at TL-T (TL 27).

• "Small" ringworlds use world and gas giant size codes.
  • Using a size code of 'Y' indicates a stellar-scale ringworld construct.
  • It's going to have a comment code of 'Ax' in every case.
  • Due to TL skew, most UWPs with a size code of Y and a comment code Ax will be ringworlds, rather than dyson spheres. Regardless, additional notes will typically be expected.
• In its prime, Leenitakot's UWP could be Leenitakot AY66C45-T Hi Ax. Up to about a thousand years after pseudo-"Leenitakot" dies, the UWP is Leenitakot AY66000-T Di Ax.

History & Background (Dossier)

The Ancients are thought to have created a ringworld in the Leenitakot system of the Hinterworlds.

• There is also a more recently created ringworld at Northstar in Beyond.

Advanced Materials Science

The construction of ringworld requires a very advanced materials technology, since the stresses of a megastructure the size of even a small ringworld would require immense tensile strength.

• Some of the most advanced material of the Imperium, Bonded Superdense and Coherent Superdense, do not even come close to the adequate material strength required for ringworld construction. Some Imperial scientists have hypothesized that it would take at least a TL19 mastery of materials science, far beyond current Imperial technology achievements, to build strong-enough materials to construct a ringworld.
• Based upon analysis of the materials used in existing ringworlds that are presumed to have built by the Ancients, the Ancients must have had an incredible materials science.
• Please see Construction Material for more information about construction materials currently available in Charted Space.

Buckminsterfullerene

Imperial scientists estimate that it would take a very advanced version of Buckminsterfullerene, or carbon Bucky Ball nanotubes, to build even a small ringworld.

Worlds & Sectors (Astrography)

Ringworlds are incredibly rare and no more than a handful are both known and can be located at a verifiable astrographic location.
