Ignorant layman's question here. Does anyone know if any of the previous or
current seti
studies have focused on the stars which are within a sphere of space
centered on earth within which
radio signals from the last hundred years (or-so, say starting with Marconi
1903 transmissions) of earth's radio-signals
could be received? I guess it would be all the stars within a 51 light years
distance from earth (taking in to account return signal
time.) Just on the off chance someone out there is listening.
