Warping space permanently so you don't have to build warp starships :)
Just kidding :)
First, define exactly what you mean by interconnectivity..
are you referring to the ability to convey information, or
materials/persons in a timely manner (which shoudl also be
defined) back and forth between planets...
On a side note, I died laughing when someone pointed out that any
advanced civilization would be
using some other carrier wave other than radio-waves (light, gravity
etc) and thus SETI (in its current incarnation)
might be a waste of time... Personally my bet is on gravity pulses..
Even better than light because (even though
it might be imperceptible), it affects everything simoultaneously...
Somebody recently asked a really intriguing
question, whats the speed of propogation for gravity :) Unfortunately
they're still constructing an experiment
thats sensitive to detect it :) I'm particularly interested in
gravity....

Subject: Re: Sol-like system discovered...SETI new directions?
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".?
