If there are many advanced ciizations out there and we don't "see" them
maybe their
communication means are just something we don't recognize. Lets assume
also that
the desire to network with others comes with a large numer of intelligent
"long-lived" civilizations.
What might be the best candidates for a means of inter-connectivity-
excluding "wharping" about in "starships".?
