Vacuuksilla

Vacuuksilla is a term used in Finnish-language science fiction and speculative discourse to describe a fictional or hypothetical group of beings or civilizations adapted to vacuous space environments. The concept encompasses lifeforms that can exist and function with minimal or no atmospheric pressure, and with energy and resource cycles based on radiation, plasma, or other non-atmospheric processes.

Etymology: The name derives from vakuumi (Finnish for vacuum) and is often used with the suffix -lla to suggest "the Vacuuks" or "those of the vacuum." In Finnish science fiction, Vacuuksilla is treated as a proper noun and appears in plural forms in narrative texts.

Concept and characteristics: In many portrayals, Vacuuksilla inhabit orbital habitats, comets, or asteroid belts where vacuum conditions prevail. Their biology ranges from extremophile lifeforms to silicon- or plasma-based intelligences, with technologies designed for vacuum operation, such as closed-cycle life support, vacuum-tolerant propulsion, and energy capture from stars or particle beams. Social structures vary from nomadic trader networks to densely organized spacefaring civilizations.

In literature and media: The term is used by several Finnish authors and game designers to explore themes of adaptation, isolation, and the limits of life in space. It is less a single canonical source and more a collaborative motif within Finnish speculative fiction.
