An anonymous reader writes "UC Berkeley Professor Walter Alvarez, most widely known for his theory that dinosaurs were killed by an asteroid impact, is developing an open source HTML5 timeline tool for visualizing all 13.7 billion years of the past called ChronoZoom. Originally conceived by one of his former students, Roland Saekow, ChronoZoom can zoom from a single day out to all of the Cosmos, passing Earth, Life, and Human Prehistory along the way. The idea and initial database was put together by students at UC Berkeley while students at Moscow State University in Russia wrote the code with guidance and support from researchers at Microsoft Research. The beta is available as of today, and the source code is available. The hope is that it will revolutionize teaching, study and research of the past."
