Multiverses

A little off my usual subjects but sometimes I like to let my mind wander a bit. I remember watching TV shows on the Universe and how there may be many Universes. As I recall, one theory was that a new Universe formed for each possible outcome of a given situation. I began to wonder if the decisions we make in our lives would move us from one Universe to another. For instance if you come to an intersection and must decide to go left or right, are two Universes created where in one Universe you go right and the other you go left? At that point wouldn't you be deciding which Universe you would be going to? Sometimes I wonder if the decisions we make move us to Universes we create for ourselves. For instance I am an agnostic when it comes to religion. Could my belief or lack of belief move me into Universes where God does not exist? On the other side, could believing in God move you into Universes where God does exist? I don't know just idle thoughts. Hey, its 1 in the morning and my mind has to do something while I am not sleeping.
