We have a close reason:
"Questions seeking scientific solutions or explanations are off-topic unless they relate directly to a cited work of fiction. There are a number of other Stack Exchange sites dedicated to answering questions on non-fictional sciences."
However, some of the questions closed under it are very interesting and good questions for those sciences.
(A recent example: https://scifi.stackexchange.com/questions/68808/is-atlanta-too-far-inland-and-too-far-above-sea-level-to-be-affected-by-the-come seems like a good question for Earth Science SE).
Should we, as a matter of policy, strongly consider migration for questions closed under this reason to a relevant SE (Physics, Chemistry, IT Security, Biology, Earth Science, etc...)
Obviously, all the usual rules around migration should apply ("don't migrate crap" and ask the mods of the target SE if they will accept the question).
However, within those rules, should we institute a rule that migration process should be initiated for almost all non-crappy questions closed under this VTC reason?
