I said "The Schrodinger equation certainly allows, in fact, requires, all four branches to be present if the measurements Alice and Bob make are independent." You dishonestly deleted the last part of this statement. If the measurements are independent, then the rules of MWI imply that all four branches are present when Alice and Bob meet. When the measurements are not independent, as when Alice and Bob measure a pair of entangled spin zero particles, then only two branches are present if the polarizers are parallel (but all four branches are present if the polarizers are not parallel). The question is, "Why is that? What makes the difference? And how is that explained locally in MWI?" You have not addressed any of the relevant questions. then why the hell did they give Schrödinger the Nobel prize for finding an > equation that grossly violates experimental results. > > 2) Why the hell are physics students still required to study such a > ridiculous useless equation that has no relation to physical reality? > The Shrodinger equation is studied because it is useful. Bell type correlations of entangled particles are also studied because they show that quantum mechanics is intrinsically non local. MWI is just as non local as any other interpretation. No local explanation of the correlations is possible -- as your ramblings have demonstrated.
