Okay, taking off again on the B5 thing, one of the more interesting themes it explored was religion as it transitioned into the stars. Whereas most of the alien races had a single religion, humanity still had as many as we do today. But would this be the case. Would religion remain a static thing, or would the realization of interstellar travel change things for these tenants?
Would a new religion emerge? Would religions begin to set aside their differences in favor of a more unifying religion like what the alien races of B5 demonstrated? These are interesting questions I think worth exploring, and I intend to do so with Flynn.
