Problematic element in chronology - Red Giants

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 don't think the issue of small black holes matters to BotNS - the black 
hole described is absorbtive, and thus large enough to have a low 
temperature.  In the context of black holes, there's actually not much 
margin between the temperature of a stellar interior and that of outer 
space.  They are either colder or hotter than either, and those that persist 
are certainly colder.
