Let this man in on the Bell Theorem.

Not being able to go from here to there, sorry.

Care to elaborate?

In short, it's a theorem proving that quantum randomness can not be the result of local hidden variables.

That is, quantum randomness is distinguishable from some hypothetical hissen classical processes we've yet to discover.

It's one of the big "well, shit"-moments for the early 20th century quantum skeptics like Einstein.

The local bit is important. Non-local deterministic interpretations are possible, eg Many Worlds or De-Broglie Bohm.

Many worlds isn't non-local, it works the same as Copenhagen when it comes to Bell's Theorem. If you're experiencing quantum effects you haven't decohered yet, and it's just bog-standard quantum physics, not a hidden variable theory.

So, it's like TRNG versus PRNG ;-)
