Abstract
If there is a relatively large number of 105 – 106 advanced civilizations in our galaxy, most of them with histories of millions of years, then they all must belong to an intercommunicating network. Also for purposes of contacting new emerging civilizations, they must have divided the whole galaxy into regional jurisdictions centered around each active member of their galactic society of stellar civilizations. Therefore, instead of hoping to receive messages from a large number of signaling civilizations, we ought to anticipate only one strong signal from our nearest civilization in whose jurisdiction we happen to belong. Hence the absence of extraterrestrial signals, rather than implying the absence of any advanced civilizations in our galaxy, may simply mean that our nearest civilization did not yet have the time or the willingness to communicate with us.
