We've had a bunch of questions of varying quality related to science fiction (or, more generally, speculative fiction), most or all asking how Jewish law would deal with some scenario that is either not currently practical or never could be.

This includes anything to do with space travel, even though it is something humans (including Jewish ones!) have done, since it's still practically out of reach for the vast majority of people and therefore the subject of a great deal of science fiction literature.

Let's make a list of all such questions that are at all valuable.

    In light of this list, should we make a [scifi] tag? – DonielF Aug 16 '16 at 21:52

    @DonielF, tags are generally meant to describe the topic in the question that Judaism relates to. Sci-fi is more of an outside interest group that might be interested in a certain subset of our questions, cutting across different realms with respect to Judaism, so I see it as better served with a catalog like this than with a tag. – Isaac Moses Aug 17 '16 at 1:09
