Force shields (also called force screens, force domes, and force bubbles) were a ubiquitous background technology in the Vorkosigan Saga. No explanation is ever given for the physics of these items, and they appear to have predated artificial gravity by a very long time. They were used for: * Biotainer girdles * Haut-lady bubbles * Building protection * Vorkosigan House * Vorbretten House * House Fell facility * An Earth home * Community domes * Beta Colony * Dagoola prison camp * Celestial Garden on Eta Ceta * Komarran cities/domes
