In incredibly simplified terms, one of the consequences of String Theory is that there must be an infinite number of universes parallel and separate from our own. If there's an infinite number then it follows that every possibility is played out. So while one universe could be radically different from ours, even having different laws of physics, another may only differ starting with a single event like a decision to turn right instead of left at an intersection. It's not clear if there is even a theoretical mechanism for travelling between these universes, and String Theory itself is only really a hypothesis for how to combine General Relativity (the theory of gravity) with quantum mechanics (the theory of the very small) into a single unified theory.
