Theres a magic door leading to a magic hallway being powered with enough magics to hold a window of every frame and point of time, even in the alternate universes and the future, having so many windows every time time is re-written the window explodes revealing the new one, in case of a paradox, the magic door has a self destruct button that if pushed the whole hallway is sent to the un ending hole in space-time fabric that is re-opened just to be closed again. This concludes my theory.
