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.

I mean, I have reviewed the same body of work on spin-gravity space 
stations available to the author when he wrote the books. Typhon's bits 
of anti-gravity technology left over from wherever would allow some very 
useful shortcuts in the process, but the fact that he had to make it a 
spin-gravity, STL habitat mean that certain constraints on the final 
configuration still apply.

Granted, but by writing about their peaks, you imply they at least 
grossly resemble earthly mountains in overall shape, and there's only so 
much that can geometrically happen with that class of shapes. And that's 
true regardless of how the mountainous pile of material came to be.
