So, you know ancient solstice markers? Like Stonehenge and the Sun Dagger in Chaco Canyon? Iād learned about them before, I knew that they were aligned with the sun and stars and stuff, and I understoodāmore or lessāthat they were impressive feats of astronomical science and engineering. But I didnāt really get how cool they were until I was watching old Cosmos episodes with my wife (high as balls, as Carl intended)
We were having a BLAST, I had my phone out, I was making calendar notifications for all the big events on the Cosmic CalendarāI had this idea that we could celebrate them like holidays, like Cambrian Explosion Day (December 15th), TITS DAY (December 26thāfirst appearance of mammals in the fossil record), The Invention of Sex (hard to pin down a day but itās early November, you could spend a whole week on it if you want), etc etc. I made them all-day events and set them to repeat yearly, indefinitely
And all of a sudden I realized, this thing that Iām doing, right now, with my smartphoneāsetting a reminder for a specific day of the year, a reminder that will alert me on that precise date and no other, and will continue to do so indefinitelyāis the exact same thing the ancient people of Chaco Canyon did
except they did it with ROCKS
they built a functional calendar alert OUT OF ROCKS and it continues to announce āHey itās that day you care aboutā ON THE PRECISE DAY THAT ITāS SUPPOSED TO, even THOUSANDS OF YEARS LATER
Fuckin hot damn man that is incredible
