Hi, Nick!

And you're right, but I was thinking specifically of "signal intelligence", as the spooks call it. Much higher v than physical expansion, but rife with problems that need no speculation.

As long as we're kicking hypotheticals around...

Four or so years back, Adam turned me on to a paper that applied percolation theory to the probability of interstellar civ's. In essence, it modified ER's condition 2 (see his post):

(2a) Interstellar colonization is possible, but limited by resources and/or a loss of motivation over generational time scales.

I also wonder, returning to my previous post, if an observer located north or south of the galactic plane, with a different angular perspective of the disk, might be more likely to receive "sigint" from other regions.
