Because we can look back and see that the way time has been measured throughout history has changed, it’s reasonable to imagine when looking forward that it will continue to change – our current use of hours, minutes, weeks and months may be as obscure and forgotten as the nundina, the akhet, or the gesh several millennia from now. The day, the year, and the movements of the other planets in our solar system, on the other hand, aren’t at the whim of the powers that be or of passing cultural trends. The 10,000 Year Clock, therefore, keeps track of these robust and durable units of time. The Clock’s main dial keeps track of the Sun, Moon and stars while The Orrery models our solar system.~ Austin Brown from, https://blog.longnow.org/02014/06/27/orrery-prototype-long-now-interval/
Immediately before reading the above article, I read something about the eastern Sahara Desert. About a researcher who managed to extract a 50-foot core-sample from a lake bed spanning 11,000 years of seasons. What is now a desert was once a lush paradise.
The projects and updates from the Long Now Foundation always fill me with awe and wonder. They always make me try to imagine 10,000 years from now. And that makes me feel like a slightly better person for having spent some time trying to think bigger-than-myself. But that core sample? …it covered still more. 10,000 years is but a blink in geologic time.
