Introduction

Science Fiction, the fictional treatment in print, films, television, or other media of the effects of science or future events on human beings. More precisely, science fiction deals with events that did not happen or have not yet happened; it considers these events rationally in terms both of explanation and of consequences; and it is concerned with the impact of change on people, often with its consequences for the human race. The most common subjects for science fiction are the future, travel through space or time, life on other planets, and crises created by technology or alien creatures and environments.
