If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
Even if such a map would exist we could only have a map of that map in our head.
Even today a lot of physicist use "natural law" in a way where they aren't clear about map/territory distinctions.
But maps of maps are supposed to be potentially 100% accurate i.e. being copies of each other? Are you saying lossless copying is not possible through the senses?
