The idea revolves heavily around the creation and deployment of several thin film-like silicon bubbles. The “space bubbles” as they refer to them, would be joined together like a raft. Once expanded in space it would be around the same size as Brazil. The bubbles would then provide an extra buffer against the harmful solar radiation that comes from the Sun.
