This series began as a way to suggest possible topics for research for those writing fiction set in the future on Earth. The list runs to 100, and so far, I’ve covered 16 in detail. However, it strikes me it might be more productive for writers to tackle those subjects they find most appealing to them. So, having suggested an approach and shown some sources that might prove useful as starting points for research, I’m now leaving it to you to decide where you want to go next with this.
For me, the primary question in science fiction is the ‘why’ of events. Why do things happen the way they do? What are the causes? Who benefits from any given political, social, commercial, or philosophical situation? You’ll have your own questions, your own themes, your own concerns. I leave it to you to decide where to go with this, and when. Below are listed the 100 topics, with links to the original posts for the first 16.

     This is my list, but you can make your own, of course. Science fiction, any fiction set in an imagined future on Earth, requires an understanding of the topics informing the story. We owe our readers the dedication of researching to ensure we have some idea of what we’re writing about, even though much of it will be speculation. Let’s make it at least ‘informed speculation’, eh?
