It’s not called “science” and it’s not called “fiction.” It’s called “science fiction,” and that means that if an author is going to successfully wade into those waters, it requires a balancing act.
Readers of science fiction are generally sophisticated. Reading science fiction isn’t easy reading. A reader needs to think and to concentrate. Science fiction places demands on a reader. That’s why it’s not the most popular genre—romance novels are. You don’t have to think or concentrate when you read a romance novel. But you do when you read science fiction. And science-fiction readers have real standards that they’ve developed by reading the great writers who developed the genre—and also by seeing countless good quality science-fiction movies and television programs.
So, when sitting down to write a work of science fiction, the writer has to rise to the standard. Bad quality science fiction is painfully obvious even to the casual reader. If a work of science fiction is to be believable and engrossing, the science in it must be plausible—and the science must be understandable to the reader.
