The many worlds interpretations assumes that the world, or rather reality itself, is not a single linear history. It asserts that there is a large number and perhaps infinite amount of universes that are manifested every second a decision or event occurs at any point in time. In lay terms, anything that could has happened, has happened, and is currently happening at this very moment. For one last example, In universe 0, Tim wants to go back in time to kill his grandfather. However, by going back in time, Tim has instead created a parallel universe (dubbed universe 1) that exists alongside his own timeline. When he kills his grandfather he is successful, but cannot return to universe 0 because the effects of him killing his grandfather had only affected this newly created timeline and not the one he came from. This means that Tim was still born in universe 0, but has now disappeared due to travelling back in time and now exists in universe 1 from which he was never
