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.

One of Clarke's laws of prediction should apply to swordsmiths as well 
as scientists, eh?
"When a distinguished but elderly scientist states that something is 
possible, he is almost certainly right. When he states that something is 
impossible, he is very probably wrong."

Unquestionably it may be weaker than a solid-core sword, but this 
doesn't mean it can't be engineered to be sufficiently strong - as 
others have pointed out we do for bridge girders.  This is especially 
true if it's built around a mercury-and-vaccuum-filled tube of 
unobtanium - I'm sure it's true that it can't be done to give the 
wonderful combination of properties seen in Terminus Est using current 
techniques & materials.  And I'm very willing to assume they can make a 
"perfect" seal around a sufficient vaccuum using some arcane machine.
