The science fiction narratives, as all narratives, part from the experience of the present, that results from a known past and contains numerous possibilities of future, all of them possible scenarios to be explored by science fiction. Several authors consider that science fiction has a goal similar to History: they both have the same will to understand the present, exploring the hypotheses of what has been and how will became a world that has no divine destiny. For that purpose, science fiction moves back and forward in an omnitemporal horizon, creating alternative pasts, dystopian futures, time travels, time loopings, time splitting and parallel time lines that dislocate the viewer from the present in order to reflect about it. This paper intends to explore these heterochronic science fiction scenarios to understand which futures our present can bring us.
