How is a superposition with two different weights for the states accounted for in the many worlds interpretation of quantum mechanics?

In the many world interpretation of quantum mechanics, after a superposition of states has interacted with some outside agent the two states smoothly continue to exist in two different worlds (so no ...

How much can investigating three nested systems help interpreting probabilistic theories?

Many attempts to interpret quantum mechanics do so by looking at three nested systems. The largest system is essentially the universe or the environment. The smallest system is the one being observed ...

Assuming we live in a simulation, does quantum mechanics exist so that freewill can be computed?

There is a chance that we live in a simulation. If we do, that might explain some of quantum mechanics. Everything is made up of 1 of 2 states. For example, you will, or will not, go to the movies ...

About the advantages of the propensity perspective on probability

I am wandering what are the advantages of the propensity perspective on probability. Why would it be better to explain probability in physics? Except for the fact that it solves various problems of ...

Relational interpretation and 'simulated universe'

With a relational interpretation of quantum mechanics, like Rovelli's, does the unverifiable simulated universe fear fall apart? Given that there are no entities 'plugged in' from the outset - no ...

Who can really work on interpreting quantum mechanics and the standard model of particle physics?

Starting from the answers to this question, even people not familiar with the interpretations of quantum mechanics can understand that physicists are not interested in substance metaphysics. This is ...

Philosophically, isn't this impossible to prove there's no hidden variable?

As Bell wrote "If [a hidden-variable theory] is local it will not agree with quantum mechanics, and if it agrees with quantum mechanics it will not be local"(https://en.wikipedia.org/wiki/Bell%...

Distributions of outcomes in Quantum Mechanics

I have read an answer here about the probabilistic nature of QM and I am curious about why QM is able to predict only distributions of outcomes of an experiment. To be clearer, is QM’s inability of ...
