The Sound and the Fury

Earth auroral kilometric radiation (radio emissions derived from cyclotron radiation) is generated concomitant to Earth’s auroras. Typically, kilometric radiation isn’t audible, but metallic particulates aloft in the upper atmosphere are now serving as transducers which downshift the emissions into audio frequency range (induced plasma discharges). That the radiation is audible suggests that the inner edge of the magnetosphere has undergone a fundamental alteration (structurally or compositionally) since the peak of solar cycle 23; in other words, the convection response of the ionosphere has been manipulated by employing methods rooted in quantum optics, of which Olivier Pfister is one progenitor, applicable both…
