1 WHAT IS BIG HISTORY? Video Talk / David Christian Big History tells the story of the Universe from the Big Bang to the present, a time span of 13.8 billion years. Big History is the modern, scientific origin story, based on the best evidence that scientists and historians have compiled to date. As new and better evidence is found, the story will need to be updated. Big History asks big questions. Among the questions that big historians tackle are: What s our place in the cosmos? Are we alone? How do we (as a species) get here? What are the big turning points in that history? What it means to be human? Are we living at a turning point of planetary history? Big History highlights the increasing complexity (and fragility) of new emerging systems with the description of threshold moments and the underlying organizing principles. It also highlights the interactions between different time and space scales, and the need to grasp knowledge across different fields of studies (multidisciplinary).

5 Big History Themes We are born curious, like to ask questions Why??? Why are we here? Is there a purpose of life? Are there life in other planets? Different cultures have different origin stories; BH provides a framework / place for us in the universe. We are taught: these questions are unimportant; should focus on more urgent matters (time scale selection) led to the impression that macro-systems (government, multinational institutions, social norms, etc.) do not change much. Big History s scientific narrative tell us that systems change all the time, and these changes are happening faster & faster, and we can either take advantage of them or being swept away by them.
