TL;DR Summary
i.e., excluded in Bell's circuit is only an unknown precondition at splitting time that would bias the spin toward an examined value.
If correct, as non-physicist, I wonder why the vast jump to "spooky action" is seen as more plausible as some new type of particle faster than the speed of light. Consider the time long before the discovery of radio communication, how weird it must have been to theorize about that. The speed of light limit extends here to even unknown objects, perhaps ones smaller, lighter than photons, and confidence in this limit is so high that we completely change our conception of cause and effect. Gravity does tug at photons, but only at light speed.

You have it backwards. It is any violation of the light speed limit that would require us to completely change our conception of cause and effect, and that is why we are so reluctant to accept explanations based on violation of that limit.

FTL communication creates the possibility that effects appear before causes and even that a message might be received before it is sent - and that the recipient of the message is then able to stop the message from being sent if and only if it has been received. These possibilities are utterly incompatible with our conception of cause and effect.

You might want to Google for “tachyonic anti-telephone” to get a sense of some of the difficulties.
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles.

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
