Science Fiction Sub-genres

Science fiction is flanked by science, without ever neglecting fantasy. You get to a point where you can't tell where science ends and science fiction begins. 

Then your fantasy appears and you begin to gallop in a universe you do not know and you are prey to the wildest imagination. 

Science fiction is a mixture of hard and soft science fiction.

• Hard science fiction strictly follows natural scientific facts and principles like physics, astronomy, chemistry, etc. For example, Gravity, the story of an astronaut whose spacecraft is damaged ...

Fantasy is a genre of fiction that focuses on imaginary elements such as superheroes, alternate worlds, aliens, etc. Science fiction may include elements of fantasy but always have a basis in science, whereas fantasy is only imaginative.
