Technology/Technological conceptions
Centurian technology was highly advanced as of the 22nd century, being able to synthesize transuranic elements without causing a short half life nor radioactivity (a ability not achieved by humans until ca. 2171).

The Centurians massive and architecturally perplexing cities and buildings were a result of decades old advancements in structural engineering and architecture. Centurians lined their skyscrapers with tungsten-iron and titanium-tungsten alloys which allowed for pressure, heat, and damage resistance.
