Well, it might be impossible, like sound on space, artificical gravity, big talking cats, ships with open hangars with atmosphere inside that can launch and land fighters, genetic-cleasing fanatics that wear glasses, big talking cats with identities overlay experiments, jump points, pilgrims, space sonars that are not really space sonars but everyone thinks they are, cloaking devices, and a lot of other things that makes WC so cool.
Or maybe there's a neat way to explain all those things, if you search hard enought.
