magic theories

hello and I figured I would just post a few ideas I had over magic and the fourth wall. first off the fourth wall I define as the object that divides and separates the many realities thus making the mlpverse quite possible. second magic is energy. it is that simple. spells just dictate how the energy is used and how much. also it exists as part of physical plane of existence not in it's own. now to connect the two concepts, the fourth wall may or may not act as a conduit for magic to pass between universes. the magic flow is what allows ponies like pinkie to peer through the wall and back into their own universe or into others.
let me know what you think of this.
