Matterspheres

Matterspheres are a conceptual element often found in speculative fiction, particularly in fantasy and science fiction genres. They are typically depicted as contained, self-sustaining environments that exist independently of the larger reality or universe. These spheres can vary greatly in size, from small personal pocket dimensions to vast planetary ecosystems. The internal environment of a mattersphere is often curated or controlled by an individual, entity, or a specific set of rules, allowing for unique physical laws, flora, fauna, and even historical timelines to exist within its boundaries.

The creation and maintenance of matterspheres usually require significant power or arcane knowledge. They can serve various purposes within a narrative, such as a sanctuary, a prison, a research laboratory, or a means of travel and exploration. Access to matterspheres is often restricted, requiring special keys, spells, or technological devices. The stability of a mattersphere can also be a plot point, with some being prone to collapse or corruption if not properly managed. The concept allows authors to explore themes of isolation, control, and the creation of artificial realities.
