universumi

Universumi is a term used in speculative fiction and philosophy to denote either the totality of all possible universes or a grand, overarching cosmology that comprises multiple worlds. It functions as a meta-framework for thinking about reality beyond a single universe. The term is not part of standard scientific taxonomy, but appears in narratives, world-building guides, and thought experiments to evoke scale and interconnectedness.

Usage and etymology: Universumi is a neologism formed by combining elements reminiscent of “universe” with plural or collective suffixes found in various languages. Its precise scope—whether it means a collection of coexisting universes, a nested plurality, or an abstract structure of potential worlds—varies by author.

Conceptual variations: In fiction, Universumi can be a literal setting where many universes intersect, a tiered hierarchy with a central meta-reality, or a navigable multiversal space accessed by gateways or powers. In philosophy, it can operate as a thought-experiment about possible worlds, contingency, and the limits of empirical science. In world-building, it provides an umbrella under which individual settings share thematic rules, cosmologies, or physics.

Relationship to related concepts: Universumi is related to the ideas of the multiverse, megaverse, and metaverse, but emphasizes a higher-order structure and totality rather than a catalog of separate realms. Its use tends to signal breadth of scope and interconnectedness more than the specifics of any one universe.
