Holtzman Waves are the one-dimensional incarnations of the Holtzman Effect/DE. They have no physical existence nor are waves but a mathematical phenomenon which causes space-time to form microcatastrophic folds along a selectable vector, causing the excitation of local matter; this produces long-wave radio emissions receivable by normal antennae. According to a theory, the background radio emissions which blanket the visible universe are Holtzman Waves transmissions of civilization in the Galactic Core. Theoretically its range is infinite.
