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.

Um, no, Jerry . . . when the Whorl is at rest, the Whorl people experience
time at the same flow as people on Urth or Blue or Green, but at near-light
speeds subjective time (the passage of time experienced by the crew) is
compressed compared to the objective time of the rest of the universe (or
technically "any other location that is not accelerated to NAFAL
velocities," which happens to encompass most of the universe).  This is the
basis of the famous "twin paradox."  (I'm not coining the use of
"objective" and "subjective" here: that is how it is done.)  Look into it,
if you like, since it is fascinating!  Or just take my word for it.
