The title of the book and eponymous exhibition at Bonniers Konsthall in Stockholm is loosely borrowed from the book "A Brief History of Time," by Stephen Hawking. When we locate a thought in outer space, our given concepts of time and space are overturned. This exhibition and publication wishes to be a springboard for artistic ideas and visions that challenge our usual way of seeing the world, perhaps also suggesting new approaches on how to understand it. These thoughts permeate the artworks and texts presented in "Cosmological Arrows" where space and the science fiction genre are an imaginary laboratory that becomes the point of departure for discussions regarding the ethical, moral and existential dilemmas of our times.
