Why does the universe work the way it does? Why are stars so big? Why are humans so small? What does it mean to be human? Big History blends geology, biology, physics, anthropology, sociology, and so much more to tell one coherent story, taking us right back to our origins and exploring how a unique series of events led to and then impacted human existence: how everything came to be, where we fit in, and even where we are going. Graphics, artworks, timelines, and at-a-glance overviews make the causes and effects of pivotal events and major thresholds in Big History instantly accessible, and evidence features explain how we know what we know. An additional 64-page reference section provides a more conventional account of events in human history. Placing humans in the context of our universe and revealing how and why we got to where we are today, Big History covers 13.8 billion years of history, from the formation of the universe and the dawn of time to the present day.
