One is
supposed to just regard as intuitive
That when
one of the branches has an overall magnitude that's zero in the sense that the number sitting in front of it in the branch is zero.
Well then intuitively it's not there anymore.
The only branches that are there are the ones that have numbers in front of them that are not zero.
Those numbers are called amplitudes.
The measurement axioms say that you take those numbers and you square them and they give you probabilities of measurement outcomes, but we can't do that in the effort approach.
We've gotten rid of the measurement axioms.
We don't want to rely on an ill-defined notion of what counts as a measurement.
So one of the things that
The advocate of the Everett approach needs to do is justify why those numbers in front of the branches that show up in this mathematical quantum state should be understood in a probabilistic way.
One of the implicit assumptions is, like I said, that when one of those numbers is zero
We can ignore it.
It disappears.
It doesn't exist.
It doesn't have any
Physical meaning anymore in some sense.
Um, the problem is that if one is just relying on these mathematical
Hilbert space axioms that just talk about this abstract quantum state evolving in time.
