Obviously, science fiction writing is all up to a writer s imagination. Some writers use so much science, they forget about the fiction. It sounds like you have worked hard to develop strong characters and storylines. So, even if someone does not have a strong scientific background they can enjoy a good story. This is an excellent observation.
Most people never realize it.
You see, there are two types of fiction, hard and soft. Some people only like the hard stuff that takes five pages to find out how a piece of machinery works. Then there are people like me who skip those pages and get to the story. I decided to write fiction for people who like to dream about things. In their magazine they publish a lot of articles about SF writing.
