THE COSMIC CALENDER
this is the image for the Cosmic Calender used on the new Cosmos series. It's a lovely piece, but I think it's meant to be a poster or something because you can't read what happens on the various dates so here goes nothing. On both programs they put a tiny little lighted square at the bottom of the last day of the year to represent the last minute and last seconds. That little lighted square is where all human history happens.
The Cosmic calendar compresses the 13.8 billion year history of the cosmos into one year. Each month is just over a billion years and each day approximately forty million years.

All early human and human evolution takes place on December 31. At 6.05 AM (15 million years ago) the first apes make the scene. At about 2.24 PM (12.3 million years ago) what can be identified as an early hominid. At about 10.24 PM (2.5 million years ago) primitive humans and the first stone tools.
In the last minute of December 31, less than a million years ago, we domesticated fire, modern humans appeared, the last ice age began and we started carving objects and painting.
In the last second of the last minute we learned how to make plants grow where we wanted them to. Learned how to harness water through dams and canals. Everything in the history books, all the people we know about. All the cities, wars, religions have taken place in the last seconds of the last minute of December 31 on the cosmic calendar including modern science, two world wars, other little wars, the moon landings and the Voyager missions. Humbling isn’t it.
