Shape of the Whorl

This is the message as the crawl holds it, before anything here touched it. What the conversation shows has been through ingest: transfer encodings decoded, attachments dropped, quote markers repaired, and the archiver’s ? resolved into quotation marks and dashes. Those repairs are judgements and some of them are wrong, which is what this page is for. Email addresses are obscured here as they are everywhere else on the site, so it is before our repairs rather than byte for byte.

Spin gravity would require all the local upward directions to point 
inward to the same axis where the long sun is to be found, preventing 
shadows of any appreciable size to be cast across valleys during the 
unshaded day. However, during the shaded night, those valleys would be 
lit from off-vertical overhead angles by their skylands, with lighter 
colors structures or ripened crops being brighter, and the closer (and 
therefore least vertical) longitudes being brighter as well.

This would allow a valley at Longitude 0? to be lit by 40 acres of flax 
at Long 45? of the same latitude as if by a rising moon, with lots of 
shadows to conceal skullduggery, but still enough ambient light to 
facilitate it.
