Based on Carl Sagan’s Cosmic Calendar and installations like the Cosmic Pathway at New York’s Hayden Planetarium, Cosmic Walk compresses the history of the universe into a five kilometer walk, sending notifications along the way about significant events in the history of the cosmos.
At this scale all of human history (from the end of the ice age, ~12,000 years ago) spans just four millimetres, about the width of the head of a match.
The app will feature a few different walks, including one that maps out the relative size of the universe and a timeline of the far future; you'll also be able to customize the distance for each walk.
Cosmic Walk will be free, have no ads, and will collect no personal information. Our hope is that the app can be funded entirely through contributions. The best way to give is via our Patreon page:
