Why do you imagine that =1931 wouldn’t be equally confusing in some future decamillenium? Arabic numerals have only been around for (charitably) 0.12 decamillenia. Sorry, =.12 decamillenia.

#42But is the star map there? This article seems to imply that it got demolished in 2022: https://www.oskarjwhansen.org/news/save-the-star-map If so that is somewhat ironic. A message intended to communicate a date to thousands of years into the future got demolished a mere 86 years after its creation due to a drainage issue and a contract dispute.
The same website says that as of 2024, it is slowly being reconstructed: https://www.oskarjwhansen.org/news/2024-hoover-dam-star-map-...

It is a convention of The Long Now Foundation to get people to think of time in terms of 10k years instead of a lifetime at best. It goes hand in hand with their 10k year clock. https://en.wikipedia.org/wiki/Clock_of_the_Long_Now
I think they are speaking to, not ignorant of, this.

#44I have once created a pendant to my friends’ wedding following a similar idea. A silver disk engraved one one side with the position of the planets and major moons at the moment of the ceremony. Fun thing is that the Galilean moons orbit fast enough that you can even read the intended minute. https://www.instagram.com/reel/DIpFTPOIP60/
If you have a blog post with a few more technical details, it may be a nice submission for HN. (Do you have a few photos of the intermediate steps to share?)
Some ideas/questions: How is it painted? Is it laser cut or by hand? Did you designed it? How did you do the calculations? Does Saturn have rings? Where is the cutoff? (No Neptune/Uranus/Fobos/Deimos/...) Have you tried to give a different size to each planet?
PS: I showed the video to my older daughter that is interested in astronomy and she likes it.

#46Thanks for this, at one point I tried to google this monument and didn't find much.

You are confusing the thing with the category of the thing. Religion the category is only a few hundred years old. The things that fall under that category go back at least as far as Neanderthal times.
The conceptualization of religion as a category, is actually quite a bit older. The idea that it was created recently was, well, created recently.[1]
Casadio details it going back thousands of years across cultures.[2]

That's so cool! Is there a calculator somewhere that can convert to/from dates and solar system position charts?
Positions at a given time could be simulated in e.g. Celestia (and then projected). The other direction, I don't know.

#50> There is an angle for doubt, for sorrow, for hate, for joy, for contemplation, and for devotion. I’m so intrigued - what was going on inside Hansen's brain?
Makes sense when talking about human postures and emotions. Victory/elation/worship corresponds to extending the arms above the head or in a "V" shape, sorrow/grief corresponds to dropping to the knees and holding the head in the hands, etc. These associations seem to persist despite language barriers and great spans of time.
You solved the riddle good sir!
Walking along the millennia, viewing the night's glorious celestial panorama, the registrations on the floor, you'll have successfully circumnavigated the long now, as well the total integral of your own life.
