- How to leave a message for the future? 2 answers
I want to write a story where the protagonists hunt down Apocalypse Repertory Caches, A.R.C.s. I had intended that A.R.C.s would be full to the brim with information: farming, medicine, civics, anything needed to give humanity a fighting chance to restart civilization.
My main question is: what would be the optimal way (least amount of degradation) of storing this information for a minimum of 1000 years?
