Differences in the epistemological description and meaning of Plank length & Plank time and the discretization of spacetime
Why does there seem to be a schism between discreteness and continuity of space and time and even in the scientific setting why isn't there a clear explanation as to what the Planck length and time ...

Can probability amplitudes be used as credences?
Probability amplitudes in quantum mechanics are sometimes called a "generalization" of probabilities. They are complex numbers a + bi. The probability associated with the probability ...

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 ...

About quantum interference: space and time [closed]
Questions that I hope are not completely devoid of physical meaning.
Firstly, about space. Let be a Hilbert space, in which we can by definition establish the existence of complete and orthonormal ...

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?
I was reading up on quantum entanglement, non locality, and how people interpret QM to still be local in the sense that it does not allow for faster than light communication signals.
I have two ...

Why things don't happen all at once?
Why was there a time between Big Bang and now?
Why it did not happen all at once?
Why is there a delay between two changes?
Why delay (time) exists?
Why are not all changes compressed into extremely ...

Does quantum superposition enable the possibility of free will?
I've been thinking about the problem of free will. In a deterministic universe, it seems like everything is just dominoes falling, one after the other. No room for choice.
But what about quantum ...

Why were the founders of quantum mechanics idealists?
Max Planck, Schrodinger, Bohr, and other founders of quantum mechanics have all expressed an idealist or subjective idealist position: in other words, they believed reality is created by or dependent ...

Is Schrödinger's cat a problem of how we define identity?
If we consider that a cat is composed of numerous atomic particles, defining particles in superposition presents no issue. A cat is a human construct to represent a grouping of atoms, and notions of ...

What are the arguments for or against the wavefunction being a subjective vs an objective entity?
This question is related to the measurement problem in Quantum Mechanics.
I want arguments in favor or against of these two viewpoints:
The wavefunction is the ontological state of existence of ...

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 ...
