Undergrad Spooky action at a distance not allowed?

Click For Summary
Sabine Hossenfelder argues that "spooky action at a distance" does not occur in quantum entanglement, stating that manipulating one particle in an entangled pair does not instantaneously affect the other unless a measurement is made. She explains that one can change the spin of a particle without impacting its entangled partner until both are measured, which challenges the notion of non-local influence. The discussion includes a debate over the interpretation of entangled states and the implications of hidden variable theories, with some participants suggesting that there may be more complexity in how entangled particles interact. However, the consensus is that no signaling is allowed between entangled particles, and any changes to one particle affect the overall entangled state rather than the individual particles. The conversation highlights the need for precise definitions and clarity in discussing quantum mechanics concepts.

If that is the case then my criticism is that she should have worded it better
You're entitled to your opinion of course. However:

Here is the picture of Stern Gerlach cascade that illustrates what I was trying to explain.
You don't need to keep belaboring this. You're just repeating yourself, and responding would just mean others repeating themselves. Enough is enough.
