The dynamics of baby universes which are branched off in pairs from a large universe and whose respective members are entangled to each other has been studied in quantum gravity and string theory. It is shown that the probability measure for such pairs essentially keeps its Planckian form when one of their two members is trapped by a Lorentzian tunnel and travels through it into another large universe, so that the two baby universes of the pairs preserve their mutual entanglement even when they are going to be finally branched in distinct large universes. The conclusion is thus drawn that big fixing the fundamental constants in our universe actually big fixes such constants in the set of all single universes of the multiverse.
