quantum mechanics - How do we know that entanglement allows measurement to instantly change the other particle's state?



I have never found experimental evidence that measuring one entangled particle causes the state of the other entangled particle to change, rather than just being revealed.


Using the spin up spin down example we know that one of the particles will be spin up and the other spin down, so when we measure one and find it is spin up we know the other is spin down. Is there any situation after creation that the particle with spin up will change to spin down?

classical mechanics - Moment of a force about a given axis (Torque) - Scalar or vectorial?

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
