A computer simulation of quantum mechanics must use a random number generator, in which case it has the Vernam cipher available to deal with Bell's Theorem. It will have buttons to ask for an action replay, a time reversal or a Lorentz transformation, and pressing any of these buttons will have the side effect of reseeding the random number generator so a new sequence of random numbers is generated. We can just get on with computer simulations without fretting about causality. Nothing can catch us out.

This is an original opinion and may breach your guidelines about original research. I am just telling it as it is.

To my untrained eye, the first paragraph in the History section seems to leave out a crucial condition for EPR's reasoning: the specific quantum description displayed in the equation applies to entangled particles, doesn't it? Any old collection of objects can't be described by the wave function stated, if there is no entanglement, right? But that's not mentioned (even though most people reading the text supposedly already know that). Wdanbae (talk) 10:16, 17 December 2022 (UTC)[reply]

That equation refers to one specific entangled state. It's not supposed to represent all quantum states, not even all entangled ones. Tercer (talk) 15:30, 17 December 2022 (UTC)[reply]

It looks like Wikipedia no longer has an article on "local realism." Should that language in this article be reworded? Yoderj (talk) 15:52, 6 May 2024 (UTC)[reply]

Local realism exists and redirects to Principle_of_locality#Quantum_mechanics. Johnjbarton (talk) 15:59, 6 May 2024 (UTC)[reply
