I get the basics of the interpretation, but I don't understand one specific element. If there are parallel worlds, where is this parallel world? Is it like a stack of newspapers, each page being a different world, where the entire, connected newspaper is the universe? What I'm asking is if this parallel world located in our universe. I'm going to assume its not in our observable universe, but what about as a whole? Is there something I'm missing, or am I confusing two theories?
