In Quantum FFF Theory, it is postulated that the Einstein Rosen (ER) “bridging wormholes”between entangled particles are the guiding channels .for Einstein Podolski and Rosen (EPR) non local entanglement even at universal distances.
So; ER=EPR is active in the Multiverse and in the lab. My Supersymmetric Multiverse interpretation of quantum mechanics is based on the idea that NOT ALL POSSIBLE ALTERNATE HISTORIES of OUR UNIVERSE need to exist if there is instant mirror symmetrical wavefunction collapse in at least two distant (Charge and Parity) mirror symmetric universes.
So I postulate that ALL POSSIBLE ALTERNATE HISTORIES of OUR MULTIVERSE exist because there is instant mirror symmetrical wavefunction collapse in at least two distant (Charge and Parity) mirror symmetric universes.
According to Quantum FFF Theory, there is no dual Cat problem based on the idea that two or more instant entangled anti-symmetric copy particles living inside different copy universes solves the dead or living cat problem. Probability philosophy based on a Charge Parity and Time (clock) symmetric copy raspberry multiverse, says that symmetry between both (anti) cats is always conserved. If The symmetric anti Cats in the anti universes are dead and in our material universes the cats are also dead.. ( 8 or 12 symmetric universe is till unclear.)
This means, that the cat in the box is dead or alive even before one is looking, because he probability is 50% by the decay of the radioactive atom in the box, which is entangled with its anti copy particles far away in one of the other universes inside the raspberry multiverse. see:
