 The other approach regards predictions for the fundamental constants, such as Weinberg’s prediction of \(\Lambda\) discussed above. The process of forming the pocket universes is assumed to yield variation in the local, low-energy physics in each pocket. Predictions for the values of the fundamental constants follow from two things: (1) a specification of the probabilities for different values of the constant over the ensemble, and (2) a treatment of the selection effect imposed by restricting consideration to pocket universes with observers and then choosing a “typical” observer.
