For questions about the fictitious in-universe science found in works of speculative fiction. DO NOT USE for questions purely concerning real-world science as they are off-topic.

Use this tag if your question is about the fictional science found in the universe of a work of science fiction or fantasy. Note that this site is about fiction, not about real-world science. Expect answers based on internal consistency or author fiat (‘Word of God’).

If your question is about:

  • how the in-universe science relates to real-world science, ask here, but do not necessarily expect answers from experts on real-world science.
  • real-world science, your question is off-topic here. You might consider asking on one of the science-based Stack Exchange sites.

Please see this discussion thread for more detail about our policy on science questions.
