Although a Darwinian evolution among universes is a strange and novel idea, Smolin believes that it can be tested by simply counting the number of black holes. Our universe should be maximally favorable to the creation of black holes. (However, one still has to prove that universes with the most black holes are the ones that favor life, like ours.)
Gobbledygook. Even if you presume the basic idea for sake of argument, how do you reasonably establish the maximal number of blackholes without studying a broad range of universes to secure a solid frame of reference? In this case, the "maximal number" will probably magically become whatever happens to be observed.
