ChronoZoom is a free open source project owned by the Outercurve Foundation that visualizes time on the broadest possible scale from the Big Bang to the present day. Conceived by Walter Alvarez and Roland Saekow, this project has been funded and supported by Microsoft Research Connections in collaboration with University California at Berkeley, Moscow State University and University of Washington Information School (iSchool), and The Center for Web and Data Science (WDS) departments.
ChronoZoom is inspired by the study of Big History, and it approaches the documentation and visualization of time and history in the same way that Google Earth deals with geography.
ChronoZoom allows users to see the true scale of time over cosmic, geologic, biological and social periods.
