Do you disagree with any of that?/Copenhagenneeds an additional postulate that Many Worlds does not, Copenhagen needs something called "measurement" that somehow causes most of those results to be completely obliterated so that only the "real" one remains.
Which is exactly what is observed.
But Copenhagen does not explain what a "measurement" is, nor does it explain what attribute the "real" one has that allows it to survive the brutal measurement process that the other results do not have.
No, but in the interventing century decoherence has explained that; something MWI takes advantage of too.
Copenhagendoes not explain why some are more real than others, Many Worlds says the obvious answer to this dilemma is that they are all equally real, so there is nothing that needs explaining.
Except how many of them are they, when exactly is the split, and how do they instantiate the probabilities that we measure.
