eigenfunction lioN 19 RBt ah of the momentum operator, it is not a legitimate wavefunction and cannot represent the particle. Question 4 of 5 1.5 Points While the uncertainty principle may be disturbing as t tells us that there are lmits to what we can know, the fact that Beli's inequality has been viclated for all experimental tests is much more disturbing.

The inequalities concern measurements made by remotely located observers (often called Alice and Bob) on entangled pairs of particles that have interacted and then separated.
If one accepts Bell's theorem: either quantum mechanics is wrong, or local realism is wrong. They cannot both be correct. So which is right? To answer that scientifically, experiments needed to be performed. It took many years and many improvements in technology to get the answer.
Bell test experiments to date overwhelmingly show that the inequalities of Bell's theorem are violated. This provides empirical evidence against local realism and demonstrating that some of the "spooky action at a distance" suggested by the famous Einstein Podolsky Rosen (EPR) thought experiment do in fact occur. They are also taken as positive evidence in favor of QM. The principle of special relativity is saved by the no-communication theorem, which proves that it is impossible for Alice to communicate information to Bob (or vice versa) faster than the speed of light.
