>if you want to duplicate a universe, there's all that matter in the second copy to make, which you've got to pay E=mc^2 for. This bothers me also, it's like every tiny quantum event creates a Big Bang in a new dimension. There is information duplication as well. Without a way to communicate between dimensions there would seem to be absolutely no way to test this theory. Maybe every quantum event is a communication? And why a new universe for every event? Why not just two universes? And how does time fit in? Maybe the second universe would be the first universe running backwards in time? The energy and information duplication seems too extreme. Could new dimensions eventually fill all possible dimensions and start to collide or overlap? Maybe our universe is a superposition of all dimensions?
