One of my most popular blog posts is my 50 Fantasy Plot Ideas and Writing Prompts, so I thought I’d share a companion post for writers of scifi and futuristic short stories and novels.

Some of these may be more along the lines of “speculative fiction” than science fiction. They include prompts about the environment, artificial intelligence, genetics, medicine, time travel, space exploration, alien races, and alternative histories. The real value of any science fiction premise or concept, of course, is the way the author uses it to explore questions about society, humanity, and relationships.

If you’re interested in publishing science fiction and you don’t have an agent, you might want to take a look at my roundup of fantasy and science fiction publishers who accept unsolicited (or unagented) manuscripts.

If you’re not writing scifi right now, but you might be in the future, you might want to pin or bookmark the post for future reference!
