Science fiction is a genre of fiction with imaginative but more or less plausible content such as settings in the future , futuristic science and technology , space travel , parallel universes , aliens , and paranormal abilities. Exploring the consequences of scientific innovations is one purpose of science fiction, making it a "literature of ideas". [ 1 ] Science fiction has been used by authors as a device to discuss philosophical ideas such as identity, desire, morality and social structure. Science fiction is largely based on writing rationally about alternative possible worlds or futures. [ 2 ] 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).
