Note that any of the root servers can be used, just in case it's the 'a'

dig +bufsize=1200 +norec NS . @m.root-servers.net
will work too. The m can be any letter from a to m.
So, if I understood you, any one of these 13 servers is the backbone
of the Internet in that THEY are the master DNS servers?
For example, if all 13 were to fail at once (just theoretical), would
the Internet stop working?
Yes and yes. If one of the servers goes down, the domain names it stores
would not be accessible, until it was replaced and restored, but any of
the root servers can be used to find all of the root servers that are working.
