Started with, "Damn, I'm full of crap.", then found "No belief is true.", and later I came across, "Nobody Home".

I imagine an empty room. Then somebody walks into the empty room through a doorway in one of the four walls. By the rules of propagation, the opposite wall has to wait to receive some kind of data regarding the presence of the person disrupting the emptiness.

Does the emptiness in (or even outside of) the room have to wait?
