Problem of Outcome & Unification Program

Click For Summary
The discussion centers on the problem of outcomes in decoherence and whether there is a unification program that can connect improper mixtures to proper ones. It is suggested that, based on quantum mechanics, a comprehensive explanation may be unlikely. The nature of the issue remains open to interpretation, with some arguing it may not be a problem at all. The equivalent decoherence issues in relativistic quantum field theory are considered to be the same. Overall, the connection between these concepts remains unresolved and speculative.

In decoherence, regarding the problem of outcomes or how improper mixture becomes proper.. is there any unification program (any papers, etc.) that can shed light on it or will the two remain forever not connected?

Not to the best of my knowledge - its based on QM so its unlikely to explain it.

It's an open question if its even an issue - nature may simply be like that.

Thanks

What is the equivalent decoherence "problems of outcomes" in relativistic quantum field theory?
 
"Supernovae evidence for foundational change to cosmological models" https://arxiv.org/pdf/2412.15143 The paper claims: We compare the standard homogeneous cosmological model, i.e., spatially flat ΛCDM, and the timescape cosmology which invokes backreaction of inhomogeneities. Timescape, while statistically homogeneous and isotropic, departs from average Friedmann-Lemaître-Robertson-Walker evolution, and replaces dark energy by kinetic gravitational energy and its gradients, in explaining...
