Our hope of receiving communications sent from outer space by extra-terrestrial intelligences must be a hope overshadowed by doubt just insofar as we conceive of these extra-terrestrial intelligences as truly advanced intelligences. This is so because any truly intellectually advanced beings that may have existed on distant planets will surely, from fear of falling back into some earlier, warlike phase of their existence still filled with pain and suffering, have long since ceased all procreation. Thus even if, due to the vast distances involved which ensure that signals sent out at the speed of light reach us only after the passing of millennia, we might still receive “messages” from such advanced intelligences, we can be almost sure that the beings who sent them have long since voluntarily “ebbed away”.
