When you repeat the 2 slit experiment you find that sometimes the electron went through slit X and sometimes it did not, but no matter how often you repeat Bruno's thought experiment you ALWAYS find that Mr. You (or Mrs. You) sees Moscow. The results of these experiments tell us that the MWI might be true but Bruno's Universal Dance Association theory is definitely wrong because it made the wrong prediction. > > I know that the MWI says I will do all sorts of bizarre things in the > next second > And Mrs. I will indeed do all sorts of bizarre things in the next second. > including spontaneously being teleported to Helsinki > True, although Mrs I also never saw Helsinki and was instead spontaneously being teleported to Moscow.
