Are questions that ask “what would the world be if X had (not) happened” on-topic for this site? What about the closely related “what would need to have changed for X to become true”?


Note that this is not about discussing specific alternate history works.

This is close to Sci-fi technology: On topic?, but there may be good reasons to allow the one and not the other.

We're not so much a site for Q&A about science fiction & fantasy, as about existing works of science fiction and fantasy. (If the question is about creating a new work, then we're redirecting them to writers).

If the question is about a general scientific or fantastic idea, unconnected to any existing work, then it's off-topic.

  • In general I like keeping as open a possible (and simply controlling bad questions, not bad topics), but this is too wide even for me. If this was ok, where would be the limit?
