Science fiction is a genre of fiction dealing with imaginary but more or less plausible (or at least non-supernatural) content such as future settings, futuristic science and technology, space travel, aliens, and paranormal abilities.
Science fiction is largely based on writing rationally about alternative possible worlds or futures. It is similar to, but differs from fantasy in that, within the context of the story, its imaginary elements are largely possible within scientifically established or scientifically postulated laws of nature (though some elements in a story might still be pure imaginative speculation).
Science Fiction writers, in many cases, are scientists, teachers, professors and experts in various technical fields. Many of the more successful authors seem almost prophetic in their stories and many like Jules Verne, Arthur C. Clarke, Isaac Asimov and others have been consultants to various technical projects and ideas which have been implemented or are in the planning stages for future completion. To primitive man, the technology of today which everyone takes for granted would be considered "black magic"! The imagination of Science fiction writers are sources of ideas which have been and still are used by scientists and engineers in creating new technological advances.
