Sci-fi builds alternative realities from current science, spanning space travel, AI, genetics, and quantum mechanics. Its appeal lies not only in scientific accuracy but also in the constraints it imposes on characters within these worlds. Audiences are drawn to the social questions it poses, exploring diverse societies, cultures, and interpersonal dynamics. Themes delve into human behavior, societal structures, power dynamics, and the impacts of technology. Mark will explore how social science influences sci-fi narratives and the insights they offer through a discussion of one of the most important pieces of science fiction: Dune.
