    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....

    omard-out

    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".?
