I have a degree in physics, and I can tell you that there is no
*observable* difference between many-worlds and any other
interpretation. As far as I know, the only thing that we can observe a
difference between is local hidden variable theories and quantum
mechanics. Google: "Bell's inequality"

I would suggest that you stop reading popular books about physics and
move on to something like Sakurai.>

Popular books tend to shroud things in nonsense because they aren't
allowed to use equations.
