The gap I still have in my understanding:
One hypothesis is that there is no spooky action. One particle was 'always' going to resolve one way, likewise with the other. Like inspecting 'heads' on one side of a coin 'forces' 'tails' onto the other side.
I accept that this coin-hypothesis has been disproved by people who actually know what they're talking about.
But to me, this implies that you should build your spooky FTL message by transmitting "Measured" rather than heads/tails:
Have an array of 8 particles at both locations. They represent measured/unmeasured rather than heads/tails. You got yourself a one-way single-use FTL byte.
For this to not work (which I'm sure it doesn't) you'd need to be unable to distinguish between a measured/unmeasured particle. To me this is equivalent of being unable to prove that there is anything spooky going on.
So how can you have it both ways? How can you theoretically know that something was sent when measurement itself would destroy any evidence of something being sent?
