Big History expands the scope of historiography to study all the past, from the Big Bang to the present.
Big History is decidedly non-anthropocentric, recognising that humans appeared only very recently from a much deeper past. The Bloomsbury Handbook of Big History brings together an international cast of leading and emerging scholars from a range of disciplines to provide the first comprehensive and balanced exploration of this new and increasingly significant field.

The handbook considers the ways in which Big History broadens the scope of evidence historians use. It reveals how Big History allows for the use of information signals from the past, such as material remains, languages, ancient DNA, and fossils, using recently discovered techniques such as carbon-dating, the extraction of ancient DNA, and the analysis of background radiation from the origin of the universe.

Understanding Big History requires an examination of the ontology and epistemology of the past and its scientific inference and representation; chapters on the ontology of the past, historical information, historiographic experiments and predictions, the origin and the end of history, historical counterfactuals, contingency, necessity, and determination and under-determination of the past are included to facilitate this understanding. The handbook also provides a sustained analysis of the theoretical assumptions associated with synthetic historical science: the syntheses of genetics, linguistics, and archaeology to infer human prehistory, quantum physics and cosmology to infer the origin of the universe, and environmental science and biology to infer the history of life; as well as the distinct historical sciences and their methods: cosmology, evolutionary biology, geology, archaeology, historical linguistics, and human historiography.

This ground-breaking volume is vital reading for all historians, philosophers and historical scientists interested in becoming more scientifically self-conscious when adopting philosophical, theoretical, and methodological approaches to the past.
