   • 2018 May 2, Mark Carnall, “What is geologic time, and how does it work?”, in The Guardian‎:

     If maths and physics are the nearest we have to a universal language to communicate with visiting extra-terrestrials, handing them a geologic time scale would be about as useful as a Jackson Pollock painting. It looks hella scientific […] but essentially it’s a very fancy way of telling the story about the history of the Earth.
