I mean, besides taking the approach to asteroids and space travel, and trying to render them realistic (which kinda breaks the theme if it receives too much attention, much as EY said “It can’t be hopping between Everet Branches, but that’s the only explanation that comes to mind, so let’s leave it for now”.
