Does ones interpretation of quantum mechanics alter one's moral philosophy?

Say one was given a trolley problem such that one outcome was certain to kill 10 people, and the other had a 1% chance of killing 100 people depending on the outcome of some quantum event, similar to ...

In the EPR paradox, what was Einstein's argument against God playing dice?

Imagine an experiment as used in formulating the EPR paradox. Say we entangle two electrons and separate them by a great distance. If we measure the z-component of spin, on one of them, sz1, we know ...

How does a many world interpretation explain an irrational number as the probability? [closed]

So in the many worlds theory my understanding is for each measurement outcome there is a world. But this does not make sense (in my opinion). Why? Because the number of worlds where outcome A is seen ...

Do scalar fields satisfy Kant's indefinitely-divisible matter thesis?

So Kant concluded vs. the Second Antinomy that matter is indefinitely divisible, so he would have taken issue with the idea that the Planck scale is the absolute limit, here. At first, I was thinking ...
