Cosmos - Wikipedia
September 25, 2025 - In October 2023, astronomers proposed a new, more comprehensive, view of the cosmos, and which includes all objects in the universe, and suggested that the universe may have begun with instantons, and may be a black hole. Cosmology is a branch of metaphysics that deals with the nature of the universe, a theory or doctrine describing the natural order of the universe. The basic definition of Cosmology is the science of the origin and development of the universe.

cosmos - Wiktionary, the free dictionary
In seeking a satisfactory formulation of materialism, it helps to employ the notion of a possible world. Possible worlds are plausibly construed not literally as universes other than the single real universe (i.e., not as cosmoi), but rather as total ways the cosmos might be—i.e., maximal properties instantiable by the single real world (the single cosmos).
