What does it mean to partition infinity in the ratio of 0.9:0.1? What is the mechanism (necessarily outside the Schrodinger equation) that achieves this?That simply means that there is as of yet no good model for QMwithout the Born rule.But there is no mechanism for the Born rule. It is inconsistent with pure Schroedinger evolution of the wave function. I think the problem of measures on infinity is overcome if you simply postulate a very large but finite number of branches to split.The trouble if the number of branches is finite is that, given thelarge number of splits since the beginning of time, you willeventually run out of branches to split.

`There's always a bigger, but still finite number. Hilbert space already`

`assumes continuous complex values.`

Or why not not an continuum probability and just measure by the density around the eigenvalueHow do you measure the density? You still need to impose a measure onan infinite set.

The reals have natural measurable subsets which define the Lebesque measure. https://e.math.cornell.edu/people/belk/measuretheory/LebesgueMeasure.pdf Brent

...the measured values are never exact anyway. I don't these things are wrong or show MWI is inconsistent, but I think they show it has just moved the problems it purported to solve off to some unobservable worlds, which is no better than CI.They show that MWI, as proposed by Everett, cannot work without suchextensive modification that it is no longer the same theory. What ismore, the required modifications are all ad hoc patches -- you loseany claim to rigour.Bruce --You received this message because you are subscribed to the GoogleGroups "Everything List" group.To unsubscribe from this group and stop receiving emails from it, sendan email to everything-list+unsubscr...@googlegroups.com.To view this discussion on the web visithttps://groups.google.com/d/msgid/everything-list/CAFxXSLRi9Zw9%3DVvy4xZCWdBvgatAP4_Zc_4V%2B7w%3DxzY254GcCg%40mail.gmail.com<https://groups.google.com/d/msgid/everything-list/CAFxXSLRi9Zw9%3DVvy4xZCWdBvgatAP4_Zc_4V%2B7w%3DxzY254GcCg%40mail.gmail.com?utm_medium=email&utm_source=footer>.
