There’s a difference between these two genres, and it’s a difference that I learn more every day. I called myself a science fiction writer, but I’m really the latter.
They share a similarity, in that their original genesis is a basis in scientific concepts — but that’s where they diverge. Good stories are the ones in which the characters are ultimately more important, but in science fiction the science has a basis in aspects that can be explained — at least extrapolated.
Science fiction can be further divided into hard and soft varieties, but that’s a separate article for the point of this piece.
As I said my current stories are science fantasy; I deal with ghosts. There’s no scientific rationale for their existence — but that isn’t a reason for me not to write this story.
Ironically, I had no interest in the sciences in high school (except for astronomy) — but my writing interest is science fiction, for both reading and writing. I guess my interest in astronomy helps for the writing…
So my current Work in Progress (WIP) is really science fantasy, not science fiction.
