Quantum entanglement just got a whole lot weirder

Note that this is weird as expected. In many calculations you must use that very different particles are entangled. Moreover, I was surprised it has not been measured before experimentally.

Moreover^2, the experiment was not designed to measure this (because everybody expect it to ne true), but to measure some internal properties of nuclei (that have a very difficult internal structure that is impossible to calculate from easy rules).
