I'm currently working on a piece based in our own galaxy a few hundred years in the future. The Republic that the book takes place in is located in the Orion Arm (the arm in which earth resides), but as you may know even this small part of the Galaxy measures thousands of light years long. The starships in this story are equipped with Dark Matter drives, which allow them to travel across the Orion Arm in about a week. But what about communications? This is where I am split. I could make things easy by introducing a kind of "dark matter communication," in which news and information could travel instantaneously from planet to planet, no matter the distance. But what I have right now is a different system. Small automated ships, equipped with their own Dark Matter drives, are loaded with data and sent from planet to planet. This would be all well and good, but two problems arise. The first is in the writing itself-- I have to take a paragraph or two to explain the important details and their implications. boooring. The second problem is that news can take awhile to spread, which has implications for the story that I'm not sure if I like. What are your thoughts? Should I go less realistic and easier, or more realistic and harder?
