Classic way of thinking tells us that one world (everything that happens 'now' at a given time, one set of simultaneous events) exists, and the other worlds do not exist, because the worlds and events of the past no longer exist, and the worlds and events of the future do not exist yet.
Our feeling of time flow tells us that only one world really exists at a time. And common sense tells us that this world is the same for everybody.
Einstein will change this view of space and time.
