If we were an alien species withe a SETI program, with exactly the same technological capabilities, how far away could we be and still detect an Earth signal that would register as intelligent life? (ignore the travel time, assume all signals have had enough time to get as far as they can, obviously if the first signal we emitted was a year ago the answer would be one light year) If the answer is longer than when we emitted the signal, when would that signal be detected by this race?
