Sci-FiScience fiction, or “sci-fi,” is one of the most popular genres of literature. It is a form of fiction through which humans have expressed their deepest and most far-reaching aspirations regarding a distant, scientifically advanced future, and it deals with topics such as future space travel, space exploration and the colonization of other galaxies, and encounters with extraterrestrial lifeforms and civilizations. Science fiction novels and films also often deal with issues common in the social sciences, such as the relationship between man and society, issues of intercultural and interpersonal interaction, and principles of justice and equality, as well as the effects of technological advancement on society and human values.

This, coupled with the richness of human imagination when it comes to the future, makes science fiction films, novels and stories invaluable not merely as a source of entertainment, but also as platforms where the imagination and the intellect can “experiment” with various ideas using fiction.

Many science fiction writers and works have become world-famous, with such masterpieces as the Foundation Trilogy by Isaac Asimov. The Asimov stories and novels, including the Foundation Trilogy, usually deal with issues of robotics, the effect of potentially intelligent robots on human society, social trends in future societies, the idea of a Galactic Empire (from which George Lucas no doubt was inspired in creating his own Star Wars universe), and other social and psychological issues.

Science fiction novels as a genre in written fiction have had a fairly long tradition, and with the invention of motion pictures, science fiction films have also proliferated, whether they are original, or adaptations of famous novels and stories on the big screen.
