All We Know We Know from Light

At the exhibition from July 30, 2018 to August 5, 2018

»All We Know We Know from Light« is a documentary about scientific research and the beauty of abstract thought. The film engages with the subject of scientific knowledge gained by optical means; that is, through observations and through the analysis of images. Astrophysical research is based on the exploration of visual and acoustic phenomena. Electromagnetic radiation allows us to gather information on the composition of objects that are billions of light years away from the Earth. Astrophysicists work on the refinement of technical instruments to create precise images of as yet unknown objects, which turns the applied imaging techniques into constitutive tools that simultaneously explore and make their research object experienceable. In doing so, they are based on conventions of perception and practicability. The film offers insights into the way data is collected on the most abstract natural phenomena and how knowledge is thereby generated.
