SUMMARY
Sabine Hossenfelder asserts that "spooky action at a distance" is a misconception in quantum mechanics, emphasizing that manipulating one particle in an entangled pair does not instantaneously affect its counterpart unless a measurement is made. She illustrates this by explaining that flipping the spin of one particle without measurement does not alter the state of the other particle. The discussion also highlights the importance of understanding the entangled system as a whole, rather than focusing on individual particles, and critiques the use of vague language in describing quantum phenomena.
