   .  You can only see this electron because you looked at it. Before that it didn't exist, or did it?

Decided to research a little more. Apparently Einstein was a thick cnut.

"Bell's theorem is a "no-go theorem", meaning a theorem of inequality that addressed the concerns of the EPR paradox of Einstein Podolsky and Rosen concerning the incompleteness of Quantum Mechanics. EPR stated that superposition of the quantum mechanical Schrödinger equation would result in entanglement, making it incomplete. John Stewart Bell was intrigued by this argument and created his inequality to disprove Von Neumann's proof that a hidden-variable theory could not exist. However, he discovered something new by rephrasing the problem as to whether Quantum Mechanics was correct and non-local (showed Entanglement), or whether Quantum Mechanics was incorrect because Entanglement did not exist. Contrary to popular opinion, Bell did not prove hidden variable theories could not exist, but he proved they had to have certain constraints upon them, especially that Entanglement was necessary.[1][2] These non-local hidden variable theories are at variance with The Copenhagen Interpretation in which Bohr famously stated, “There is no Quantum World.”[3] In the latter, the measurement instrument is differentiated from the quantum effects being observed. This has been called The Measurement problem and the Observer effect problem.

In its simplest form, Bell's theorem rules out local hidden variables as a viable explanation of quantum mechanics[4] (though it still leaves the door open for non-local hidden variables, such as De Broglieâ€"Bohm theory, Many Worlds Theory, Ghirardiâ€"Riminiâ€"Weber theory, etc.).

Bell concluded: “In a theory in which parameters are added to quantum mechanics to determine the results of individual measurements, without changing the statistical predictions, there must be a mechanism whereby the setting of one measuring device can influence the reading of another instrument, however remote. Moreover, the signal involved must propagate instantaneously, so that such a theory could not be Lorentz invariant.”[5]"

It would seem that once you're entangled you will never get out of it no matter how far away you fuck off.

Even light years.

What in the fresh fuck are you going on about?

"If you think you understand quantum mechanics, you don't understand quantum mechanics."

So says one of the foremost experts in Quantum Physics - Richard Feynman. I've read bits about Quantum Physics and it is great if you want a complete mind fuck. It just doesn't describe the world as we see it at all. But yet it is in use all around us in modern tech and so certainly applies just not at the scale that we see. Therefore it is very difficult to grasp. Real world magic.

Oh right, nice one.

Super interesting shit...but yeah like Gav said...a complete mind fuck. 

Recommended reasonably accessible books on the area:

QED (Feynman)
Six Easy Pieces (Feynman)
Seven Brief Lessons on Physics (Carlo Rovelli) - nice and short that one!
Reality is not what is seems (Carlo Rovelli)

Get them on your Christmas list, Aaron  8)

Whatever you do don't confuse him and mention the multi-verse theory.

I don't get the sllit experiment, I am however reliably informed that BBM is an expert.

Ye nice one.

Entanglement is true. this basically means our understanding is fucked.

Some light reading.
