The great Polish writer, Stanislaw Lem (he wrote the novel Solaris among other things) developed a theory of fiction writing based upon the idea that no matter how far-fetched the story or how wild the setting, that it should nevertheless be internally consistent down to the tiniest detail. Then and only then, will the far-fetched or even the impossible not only become believable, but also make a world we could live in.
Good advice! Authors, be consistent!
Keep sending those stories into Electric Spec.
