I see what you mean. It's not like I would ask you how it actually works or have Lancer talk about it so much as it is a conceptual thing. 

Alternatively I could spin it as more of a theory disproving thing based on the destruction of geocentrism. Like "What you're doing doesn't make any sense physically speaking!"

Either way it's important to remember the amount of effort that is required to pull it off. He has to get into a fight or watch one happen, then go home and think about what he saw, then later if the same enemy shows up he can put a few rank-downs on the ability in question.
