My point about locating events is that the mathematical purpose of dimensions is to measure things in relationship to one another. Dimensions in a Euclidean space are orthogonal and certain relationships apply in these spaces such as the lengths of vectors being the square root of the sum of squares on the projected lengths of the vector against some basis vectors. So in any four dimensional space you could locate two points and measure the distance and define their locations within the four dimensional space. But with quantum mechanical branches you definitely cannot do this. There is no shared Euclidean space like that. Also your argument only makes any sense in some limited scenarios like the double slit experiment. In other complex wave functions with very high dimensionality, this idea simply breaks down. I strongly recommend Leonard Susskind’s “theoretical minimum” book on quantum mechanics if you really want to understand the subject. Your remark about “spatially accommodating” the branches reveals that you don’t really understand this subject. No such accommodation is necessary. You are still thinking about the quantum world through a classical mindset.
