The Celestial Modulator questions time and space. Radio signals, from the point of broadcast, travel at the speed of light away from earth. Are these signals in our past? No, they exist in the present, light-years away in the outer depths of space.
This piece allows you to listen to old radio signals....there are some side effects however. Strange signals and unknown transmissions of unknown origin are picked up as well. Put on the headphones and tune in.
