Is the notion of a fuzzy reality coherent?

Can reality be fuzzy? If so, how would this look like? In quantum mechanics, a particle can be in a superposition of two states before measurement. In the many worlds interpretation, this is neatly ...

Is the universe "one-sided"? [closed]

I have asked this question on Physics Stack Exchange, but it was closed because it does not deal with mainstream physics, that is, physics for which some paper has been published. I think it is worth ...

Why do most philosophers believe in a deterministic formulation of quantum mechanics?

After stumbling upon this recent survey from 2020, it is interesting to see that the most popular position (apart from being undecided) is hidden variables at 21.94%. As a reminder, a hidden-variable ...

Why do particles need a signal to travel to another to affect it?

What are the ontological implications of that “the universe is not locally real” in quantum mechanics?

Quantum mechanics is said to indicate that the universe is not “locally real”, because a particle is not in a defined state before measurement. But if a particle is not in a defined state, what is it ...
