A Walk Through Time depicts the 4.6 billion year story of our Earth and progresses from the formation of our solar system to the beginning of life on Earth to the present. The Walk offers a rich context for exploring fundamental issues regarding humanity and the future of all life on Earth. The Walk Through Time exhibit was imagined by physicist Sidney Liebes, who wanted to inspire people with the magnificent story of life on Earth and provide a cautionary tale of how human actions today threaten Earth’s diversity and stability. The University of Montana (UM) has one of the few copies of the physical exhibit and periodically displays it on the UM campus. View the Walk Through Time digital archives to learn more about the exhibit and the individual exhibit panels.
