Off topic but apropos of the Hebrides and their ancient rocks (Lewesian Gneiss dating back 3.5 billion years) is this fascinating look at the timeframe of life on earth. The perspective of passing events puts us in our place -- and makes any reflections on a place like the Hebrides islands even more humbling. Enjoy and I'll be back to finish the Hebrides series soon. http://seedmagazine.com/content/article/the_evolution_of_life_in_60_seconds/?utm_source=feedburner&utm_medium=feed
Truly amazing, Jim. That makes me remember the Cosmic Calendar, popularized by Carl Sagan's "Cosmos". In that calendar the history of the Universe is one year. In such scale, the formation of the Earth occurs on September 3rd, the dinosaurs go extinct on December 30th and all human history (from the time of the caves) would be the very last few seconds before the end of the year.
The scale is 434.4 years per second in the Cosmic Calendar.
