I have a side project distracting me that I like to call a sci-phi story. It touches all sorts of arguments ranging from the origin of the universe, free will, the existence of God, a self aware universe, multiverse, etc. I've been told the story is a good one and I believe I can write it well. My problem is this: The story has to have a conclusion or lead to the point where the reader can decide the most likely outcome on their own. However, I do not want the book to convey a message of my beliefs or lack thereof; I simply want to bring the topics up and make people form there own quetions. Does this make the book weak? Does an author need to take a side if they are going to write a story with such arguments?
