No one has defined science fiction to everyone's satisfaction.One can say that it is a popular form of literature with technology interests that has developed in the twentieth century.It has also become a popular kind of movie.
Two of the earliest writers were H.G.Wells,and the Frenchman,Jules Verne,whose many books include A journey to the Centre of the Earth.Most science fiction writers imagine what will happen in the future,given current technological developments.Many have a deep moral sense,and agree with Ray Bradbury's comment:“I don't try to predict the future; Itry to prevent it.
