Cosmic evolution

is the scientific study of universal change. It is an intellectual framework that offers a grand synthesis of the many varied changes in the assembly and composition of radiation, matter, and lifethroughout the history of the universe. While engaging the time-honored queries of who we are and whence we came, this interdisciplinary subject attempts to unify the sciences within the entirety of natural history—a single broad scientific narrative of a possible origin and evolution of all material things, from an inferred big bang to humankind. (Closely related subjects include epic of evolution, big history, andastrobiology). It makes use of ideas of information theory, chaos theory, complexity, systems, and emergence.
