**Why “quantum entanglement” (specifically, the popular interpretation thereof) is absurd:**

(1) It is based on the Copenhagen interpretation of the Uncertainty principle in quantum mechanics.

(2) It says that the observed states of “entangled” particles are necessarily correlated upon observation. It also says that the states remain properly/truly random until they are observed.

(3) It then concludes that when particles A and B (which are entangled to each other) are separated over large distances, the fact that the subsequently observed state of A is correlated with the observed state of B implies that the particles have somehow instantaneously communicated/propagated their settled states to each other, as if there were some direct causal relationship.

This popular interpretation of “quantum entanglement” is absurd because the Copenhagen interpretation of quantum mechanics is inherently false. (reference: http://bayes.wustl.edu/etj/articles/cmystery.pdf)

Clearly, the states of entangled quantum particles are not truly random. In fact, the process of “entanglement” is the direct cause of the subsequent correlatedness of the observed states of A and B.

If physicists simply allowed the observed correlatedness of A and B to falsify the principle of “randomness” underpinning the Copenhagen interpretation, they would not need to insist on the absurd concept of “spooky action at a distance“.

**In short:** the entanglement process itself is what causes A and B to be correlated upon subsequent observation. Quantum states are not truly random after all.

**Simply put:** correlation does not imply causation. Randomness is not real, not even at the quantum level.

**Example:** if I pre-calibrate (“entangle”) two gyroscopes A and B to spin in the same orientation, then no matter how far apart I physically separate them, the observed orientation of A is always going to correspond to that of B. (There is nothing mysterious about this!) The only difference in quantum mechanics is that physicists are not able to see the orientations with their eyes, and can only “touch” the gyroscopes. Also, “touching” inevitably changes the orientation, momentum and position of each gyroscope.
