: suggesting that something bad is going to happen in the future.
What type of writing grabs your attention? Draws you in? Myself, I am a sucker for almost any story that suggest something dark, sinister or evil lurks in the path of the hero. A sinister omen or dark prophecy come true that changes the hero forever.
People have used science all the time to put the fear of something bad coming. Things like the near collision studies or global warming. Heck, even most religions, if not all, tell tales of dark times coming and end of life prophecies. There is something about the specter of something sinister and unknown that keeps us on our toes.
Science fiction novels almost always build their stories around the tales of good vs. evil. The way of life is preparing to change and the forces of good need to rally together to fight the forces of evil and keep natural balance and order in place. Star Wars, Star Trek, Battlestar Galactica, Lawnmower Man.
Any time science and science fiction collide, it seems we find ominous overtones. Typing the process and flow out seems so easy. But I have found actually doing it is a whole different ball game. And a fun one at that.
