Quantum Entanglement Phenomena between Entangled Quantum Particles Empirically Exemplify and Prove the Law of Cause and Effect

 Physics insight of the moment, on quantum entanglement:

When a behavioral trait, such as the spin direction of either of two entangled partner quantum particles, such as of microwave frequency photons, changes in one of the two entangled quantum particles, it instantaneously, across any length of space and time separating the two entangled particles, registers, or instances, an opposite, corresponding behavioral trait in the co-entangled partner particle (For instance, if particle A spins to the left, then its partner particle B spins to the right, and if particle A spins upward, then its partner particle B spins downward, and vice versa.), exemplifying, manifesting and empirically confirming the law of cause and effect at the fundamental quantum microcosmic state of existence and cosmology -- perhaps, arguably to some physicists, it evidences a linear, 100%-functional correlation in behavior between the two entangled particles. The definitional law of cause and effect states that for every action there is an opposite and equal reaction.
