What's So Great About Ushas?

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.

Kills all life above ground on the Sirius-facing hemisphere and poisons 
the atmosphere. But this won't happen until you see 40% of the sun's 
mass flow from Sirius A to Sirius B.
