good points, but signal strength decay in the semivacuum of space really has to do more with the geometry of your emitter path vis a vis a fixed target (earth).

good points, but signal strength decay in the semivacuum of space really has to do more with the geometry of your emitter path vis a vis a fixed target (earth). so we get attenuation from the voyager but you can bet your sweet patootie that voyager is broadcasting our business to a gajillion other star systems even with a weak signal. in which case deflections from the intergalactic ambient hydrogen is the only hope of mankind that they don't invert the signal back to our solar system with our primitive space force.
