>Entanglement isn't like how it's described in the post at all. Entangled particles are correlated across spacetime in a way that goes beyond "instantly knowing there is red in one envelope when blue is in the other". When I watched this on YouTube yesterday, I knew that as soon as she used the sock example that someone would get salty about it without listening to the rest of what she says. She addresses this right towards the end: "Yes, that explains the case for the socks. But in quantum mechanics, that explanation does not work. If you think that really it was decided already which spin went into which direction when they were emitted, that will not create sufficiently strong correlations. It’s just incompatible with observations." >So I imagine Einstein meant both I think her view is that when Einstein said "spooky action at a distance" he was referring SPECIFICALLY to the instantaneous effect of measurement on the wave function. Entanglement, then, is just an example of this where we can increase the distance in the lab to experimentally confirm the implication.
