The most near intelligent civilizations might be 47-100 lights years away, according to some rogue estimates derived by modified differential Drake Equations.
Would we detect E.T? Would they even use the same technology as we do? Can we detect directed "phased array" communications at such distances? What if they use frequency hoping or spread spectrum like our cell phones now use for security, efficiency and directionality? Is a narrow band search a futile effort?
