Each episode of Big History will begin with an iconic topic from the pages of traditional history such as the Great Pyramids, The Titanic or the American Revolution but then will spin into surprising journeys through other fields, weaving together insights and evidence from various disciplines such as astronomy, physics, chemistry, biology, anthropology, history and economics. Spanning 13.7 billion years, Big History will ultimately pull together the puzzle pieces from all 16 half-hour episodes into an epic two-hour finale, creating one grand narrative and revealing the unifying link among all events.
