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.

Ahem back.

You're right, of course.  My training is in mathematics, not=20
geological/planetary science.  Still, I should have thought of that.  My=20
tendency seems to be jumping in with my "ideas" without fully examining=20
other alternatives.

Still, there's no denying that even if Green orbits Blue, it doesn't=20
orbit it in the same way that Lune orbits Urth.  That was one of the=20
points I was trying to make and I got sidetracked talking about orbits=20
and such.

Sheepishly,

Charles
