The working group "Xeno-Architecture and Knowledge":Other Spaces of Science Fiction” aims to explore alien, utopian, and contingent spaces of science fiction. During the 1970s, mostly young architecture collectives such as Superstudio, Archizoom, Archigram, or Haus Rucker & CO engaged with visions of spatial, social, or economic utopias in order to create mostly graphic representations but also narrative transformations. What is the relationship of these architectural concepts to contingent spaces from science-fiction literature and film? Do they create openings toward what is alien or contingent, or to other spaces? Or do they confirm what is known? Do they suspend physical or biochemical reality, or do they continue to set the conditions for these spaces? Can these xeno-architectures make it possible to think other spaces? Or do xeno-architectures principally resist thought, inasmuch as spaces are essentially contingent upon their expansion?
