For me, I've always preferred the work of fiction to not attempt to explain and validate these things. I already know that it's bullshit, and nothing will make it stop being bullshit. Thus any attempt to talk about it like it isn't bullshit is A) a waste of time, and B) an insult to my intelligence.
The only time a detailed explanation is worth something is if it is of practical plot importance, and if that be the case, the author must try extremely hard to not forget or break their own rules. Man that pisses me off.
