“Or.... proof that with an almost infinite amount of particles in the Universe, it is possible to find particles that have ‘mirrored’ behavior.”
No, they actually create pairs of entangled particles in experiments, and then observe this behavior. They are not just taking one particle and searching for another in an analogous state.
Hmmmmm... how do they 'create' this entanglement?
If the entangled pairs are 'created', then it's not really proof of any natural occurrence, is it ?
Also their claim that one of the pair could be 'here', and the other somewhere billions of miles away out in the Universe... also precludes any possible 'proof'.
