Hello and than you all for taking the time to read this. I've been trying to write a story that takes place in a futuristic setting, about 1,600 years after a period where Earth becomes uninhabitable. The problem is I really don't know exactly what I need. I know space is BIG so I figured I could use more imagination than anything, but should I be doing more research on what is and isn't known about our massive back yard the Milkyway? I plan to have my story taking place in numerous regions of space, with in an acceptable boundry of course, and more than once the battles take place in the middle of no where. So I really wasn't concerned about the overall setting. Should I center the setting more around planets and solar systems or would being in the middle space at certain times be acceptable? Thank you everyone for your input!
