Hi, I don't quite understand some central points of the many-world interpretation: When does the splitting happen, and is there superposition in a single universe? I see two alternatives: 1. There is superposition in a single, and this universe splits when we measure. This means we can start with only one universe which branches out more and more. 2. There is no superposition in a single universe. We just find out about which universe we're in when we measure. Both of these alternatives are not satisfactory to me at all. In the first, I can't see the "advantages" over Kopenhagen, because the measurement is still a very special process, namely it causes a whole universe to split! The second is even weirder, it would imply that from the beginning there are already enough universes (an enormous number) for all possible superpositions to come. But how do these universes know in which basis we are going to measure? We would have to give up every bit of free will. On the positive, a measurement would really be nothing special at all. Which of the two is more accepted (or are there more interpretations)? Both seem very implausible to me.
