If magic existed, it'd be a bigger break of physics if words were invovled, since that would suggest the physics of such a universe would be inherintly in that language, esepcially since such a univers would have to have those physics in place from the Big Bang, eons before said language was even invented, and perhaps even then, additional magic along the line of psyonics would have to be involved.

Therefore, if there's a universe where magic of some kind exists, it'd prolly be more along the lines of Airbending.

Therefore, M Night Shamalamaham couldn't make a belivable film in ANY reality.
