Tetragraviton puts it nicely:
"you still can’t tell if the other person “collapsed it first”. So whatever sort of “instantaneous change” is happening, it’s not something you can do anything with, or measure".
However , ENTANGLEMENT DOES NOT WORK FOR PERSONS IN THIS WORLD. Only for anti symmetric particle spin.
FOR PERSONS IT WORKS ONLY in the Charge Parity symmetric Raspberry Multiverse you can measure the number of universes out of the avarage ratios of the "Readiness Potential" differences long and short, (B. LIBET) between test persons pressing electric knobs at ALL entangled ANTI COPY UNIVERSES NEARLY AT THE SAME INSTANT.
see: "Bohmian Double Slit Interpretation by Dual Entangled Universes, and the Benjamin Libet Experiment."
