I'm perfectly happy with "it's magic" being an excuse; always worked for Thor before in the comics. Despite some people wanting to turn Thor more towards sci-fi than fantasy, the fact remains that the Asgardian milieu is straight-up Dungeons & Dragons/World of Warcraft, and always will be.
The only thing I'd really want explained (and not in technical detail, mind you --- just story logic) is how they travel between worlds. Or planes. Or planetoids, or dimensions, or what the **** ever. Just set some basic guidelines for that, and stay consistent with it from movie to movie.
