Big History is an academic discipline that examines history from the Big Bang to the present. Big History resists specialization and searches for universal patterns or trends. It examines long time frames using a multidisciplinary approach based on combining numerous disciplines from science and the humanities. It explores human existence in the context of this bigger picture. It integrates studies of the cosmos, Earth, life, and humanity using empirical evidence to explore cause-and-effect relations. It is taught at universities as well as primary and secondary schools often using web-based interactive presentations.
