Earth Signal Universe Wide is a radio sculpture created via radio transmission performed by several earth-bound stations as well as the International Space Station. The transmission’s magnitudes expand beyond the confines of the solar system, get refracted by celestial objects, travel at the speed of light through the vacuum of space and dissipate as they travel away from the locus of transmission on the ISS. Radio waves inside earth’s atmosphere and ionosphere encounter damping caused by surfaces, the air, and geomagnetic weather, and will always eventually dissolve in such a material environment. In space, radio waves never lose their energy, only decrease in amplitude as they fanout onwards and away to infinity. Earth Signal Universe Wide is thus a gradient of energy, a never-ending brush stroke that begins at the International Space Station and ends at the far reaches of the universe. The carrier wave transmitted to the ISS is modulated by a signal generated by a seismometer installed on earth, delineating an earth signal as large as the cosmos itself. The work is thus cultural and human: the transmission of a message from earth’s inhabitants that is an expansion of the earth in and of itself.
