"been teaching literature for over 35 years"

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.

It doesn't matter (in engineering terms) whether stuff that reaches the 
event horizon goes somewhere else or not (that's kind of the definition of 
an event horizon).  But an accretion disk outside the Schwarzschild radius 
is just standard dynamics for any super-condensed object.  At a distance of 
several Schwarzschild radii, Newtonian physics will be reasonably accurate 
(albeit not in detail).
