- Most sci-fi takes place in the future or the near-future. Where does yours take place? Why does it take place in that time period? Once you know when it takes place, figure out the society. You’ll need to know how society got to that point and why. Was there a war? Did one country become two because of that?
- Other than the time period you’ll need the actual setting. Does it take place in space? On a planet? Where on that planet? Or does the setting change because of travel?
- The less you know about science, the softer your sci-fi will be. Take what subject you know most about (biology, chemistry, ecology, etc.) and use that for most of the science stuff, as long as your confident in your knowledge. However, keep it general and broad.
- Technology advances more and more each day, much more than it did one hundred years ago. Establish the technology of your world and how quickly it evolves. Decide what is common place and what is rather new. Do only certain people get certain technologies? Why?
- With more advances in science comes better medicine and probably longer life. Think about how long your characters are likely to live and establish what medicines are available (like if there is a cure for cancer or if certain diseases have been completely wiped out).
