From Quantum Reality by Nick Herbert
Arguing from quantum theory plus a bit of arithmetic, Bell was able to show that any model of reality whatsoever--whether ordinary or contextual--must be non-local. Bell's theorem has since been proved entirely in terms of quantum facts, no reference to quantum theory is necessary. In its most up-to-date version Bell's theorem reads: The quantum facts plus a bit of arithmetic require that reality be non-local. In a local reality, influences cannot travel faster than light. Bell's theorem says that in any reality of this sort, information does not get around fast enough to explain the quantum facts: reality must be non-local.

"Bell's theorem proves that any model of reality, whether ordinary or contextual, must be connected by influences which do not respect the optical speed limit. If Bell's theorem is valid, we live in a superluminal reality. Bell's discovery of the necessary non-locality of deep reality is the most important achievement in reality research since the invention of quantum theory."

oh thats odd. Didnt think i needed to learn this. Is this some how defying what einstien said about quantum physics?

according to a couple of sources, the paper it was first proposed on actually works to complete the Einstein/Podolsky/Rosen paper.

I'm more of a mathematician than a physicist. And I don't know much about Bell's Theorem either.

From what I can think, If Bell's theorem was a Law, then this world would in fact might be a figment of out imagination in terms of "where is where" and "what is where". If things need influence, they must be programmed to do so...

Yea same im more a mathematician myself. Done and dusted with physics. Maybe evil might know?

All I remember from Physics A level was the quote "if you think you understand quantum mechanics, then you don't understand it at all". And that was enough incentive not to even bother revising it lol
