Tilen Sepič: Cosmic Rain

24. May - 19. June 2021

Light and sound installation as part of the Light Guerrilla Festival in the Small Gallery of Banka Slovenija

Light-sound installation represents the voltage of a wire network that connects devices – cosmic ray detectors, assembled with the help of light or kinetic elements. The glare of light and the movement of electromagnets that generate sound depend on the captured signals from muon detectors, which were artistically crafted after viewing the open source Cosmic Watch (MIT) project. Muons are invisible particles that form on Earth in the upper atmosphere when they are hit by “cosmic rays” – high-energy particles that originate from the depths of space; it is basically a pair of elementary particles with positive and negative electric charges and extremely short decay times. Particles shoot at any material, stopped only by the thickness of our planet. The spatial layout is set with abstract and minimalist vocabulary that attempts to visualize an invisible natural phenomenon; it thus allows the viewer a sensory experience of physical and cosmic events that are all around us but thus inaccessible to our senses.
