All the the the if I rewrite, which I can do, the singlet state, instead of expressing it in terms of X spin, I express it in terms of Y spin or in terms of Z spin or in terms of forty-five degree spin up to a constant, it always takes exactly the same mathematical form.
And that therefore the EPR argument can be run.
In exactly the same way for all directions.
That's gonna be important.
Now, suppose we had a causally local theory.
Again, suppose that nothing that Alice does, nothing about which direction she decides to orient her magnets makes any difference at all to what happens in Bob's lab.
Then I can run the EPR argument for all of these directions and say, well, in a local theory, it must be that the outcomes are predetermined.
In all directions.
Because remember, the EPR criterion of reality is just if you can make the prediction.
without disturbing the system.
And Alice can make a prediction in any direction.
Whatever direction she wants.
If she wants to predict Bob's in the x direction, she just checks the x direction in her lab.
If she wants to predict Bob's in the y direction, she checks the y direction in her lab, and so on.
So she can do it in any direct in any direction.
And if you say there's no spooky action at a distance, none of those things she can do would disturb Bob's particle.
Therefore, Bob's particle has to be predetermined in its behavior in any direction.
It has to, as we sometimes say, come with an instruction set.
that tells it what to do if it encounters a Stern Garoch magnet, no matter how that Stern Garrach magnet happens to be oriented.
That's j the only way a local theory could make these predictions.
