ChronoZoom is a free open source project that visualizes time on the broadest possible scale from the Big Bang to the present day.

[1] Conceived by Walter Alvarez and Roland Saekow and developed by the department of Earth and Planetary Science at the University of California, Berkeley in collaboration with Microsoft Research and Moscow State University, Alvarez unveiled the first ChronoZoom prototype at UC Berkeley's 2010 Faculty Research Lecture.

[5] ChronoZoom allows users to see the true scale of time over cosmic, geologic, biological and social periods.

[6] The primary goal of ChronoZoom is to make time relationships between different studies of history clear and vivid.

The 1.0 proof of concept was released on April 29, 2010 at the 97th Annual Faculty Research Lecture Series given by Alvarez.
