What kinds of worlds will exist in our future? How will countries, cities and homes be shaped by advanced technology? What forms might we ourselves assume? The genre of science fiction provides countless possibilities for imagining new types of spaces—from utopias and dystopias to alien environments, and to purely mechanical or mutant cityscapes. This collection gathers together papers originally presented at the 2018 Science Fiction Symposium at Tel-Aviv University, a two-day conference discussing new concepts of space in science-fictional works. Featuring a transmedia approach by contributors from around the world, this volume discusses a wide and diverse array of issues in the ever-expanding field of science fiction studies, including capitalism, equality, revolution, feminist critique and the humanity of the Other.
