Since the turn of the previous century, science fiction and its native tropes have been used by authors, artists, filmmakers and critics in order to challenge boundaries - whether these be conceptual, literary or metaphorical. Uniquely inherent to the genre is its ability to explore, as a form of thought experiment, different ways of crossing and subverting borders previously thought to be inviolable; these transgressions and their effects on popular culture have in turn led to an increased presence of science fiction studies in academia.This volume features papers presented at the 2014 and 2015 Science Fiction Symposia, held at Tel-Aviv University. These essays, submitted by an eclectic mix of scholars from different disciplines, institutes and walks of life, demonstrate the diversity and adaptability of science fiction as a tool for asking - and answering - impossible questions.
