This proves the existence of influence at a distance whenwe suppose that a measurement gives an outcome, but in QM withoutcollapse, a measurement gives all outcomes, with varying relativeprobabilities.

`The measurement on one of the spin-half particles in the singlet state`

`has only two possible outcomes. As is often said in discussions of`

`non-locality in Everettian QM, 'measurements that are not made do not`

`have outcomes!'`

You did not. You have even considered a singlet state like if itinvolves 4 parallel universes, when it involves infinitely many. Seemore in the archive.The singlet state involves only four possible combinations ofexperimental resultsWe have discussed this, and I have never agree with this. The singletstate (in classical non GR QM) describes at all times an infinity ofcombinations of experimental result.

`This is false. Even in Everettian QM there are only two possible`

`outcomes for each spin measurement: this leads to two distinct worlds`

`for each particle of the pair. Hence only 4 possible parallel universes.`

`Where do you get the idea that there are infinitely many parallel`

`universes? This is not part of Everettian QM, or any other model of QM.`

`But even if you can manufacture an infinity of universes, you still have`

`not shown how this removes the non-locality inherent in the quantum`

`formalism.`
