Science-Fiction has a lot of history. The first antecedents from this genre were found out by Historians from the 2nd century. In this era, they were using speculation and storytelling to understand the world and creating a dividing line between the mythological and historical tends. Thus, they were trying to make the difference between actual situations that happened and others that were only based on beliefs and had not enough possible facts to happen.
After a while, Science-Fiction continued to evolve after the 2nd century, but its bigger development occurred in the 19th century with the arrival of the first science fictions novels. This development occurred mostly because of the arrival of some significant technological advances such as electricity, telegraph and so on, in modern societies, which ultimately change science. An excellent example of the use of these new technologies was in Frankenstein. Moreover, the genre continued to evolve and became what we are used to seeing nowadays, which is mostly works that demonstrate potential innovation and new technologies.
Furthermore, the genre nowadays mostly consists of speculative fiction, which is a narrative based on supernatural and futuristic elements. It also deals with original concepts such as futuristic science, technology and extra-terrestrial existence that are most of them based on science and theory, instead of only creative thoughts.
Finally, the genre became so popular and so diversify that Sci-Fi needed to include sub-genre. Thus, it was divided into two significant sub-genres: Hard Science Fiction and Soft Fiction. Their primary differences are that hard science fiction usually includes attention to detail in the natural sciences like physics, astrophysics, and chemistry. On the other hand, soft science fiction is based on social sciences such as psychology and economics.
