The Drake Equation[0] is probably the most famous attempt at a "resolution" to the Fermi paradox and I haven't seen any that realistically try to implement a term involving the likelihood that a civilization might colonize neighboring star systems. Would a civilization that has colonized multiple near-by star systems be considerably noisier/more-detectable than one confined to a single star system?
