Now a similar problem afflicts the contemporary appeal to the multiverse to explain away fine-tuning. Roger Penrose of Oxford University has calculated that the odds of our universeâs low entropy condition obtaining by chance alone are on the order of 1:1010(123), an inconceivable number. If our universe were but one member of a multiverse of randomly ordered worlds, then it is vastly more probable that we should be observing a much smaller universe. For example, the odds of our solar systemâs being formed instantly by the random collision of particles is about 1:1010(60), a vast number, but inconceivably smaller than 1010(123). (Penrose calls it âutter chicken feedâ by comparison [The Road to Reality (Knopf, 2005), pp. 762-5]). Or again, if our universe is but one member of a multiverse, then we ought to be observing highly extraordinary events, like horsesâ popping into and out of existence by random collisions, or perpetual motion machines, since these are vastly more probable than all of natureâs constants and quantitiesâ falling by chance into the virtually infinitesimal life-permitting range. Observable universes like those strange worlds are simply much more plenteous in the ensemble of universes than worlds like ours and, therefore, ought to be observed by us if the universe were but a random member of a multiverse of worlds. Since we do not have such observations, that fact strongly disconfirms the multiverse hypothesis. On naturalism, at least, it is therefore highly probable that there is no multiverse.
All this has been said, of course, without asking whether the multiverse itself must not exhibit fine-tuning in order to exist. If it does, as some have argued, then it is a non-starter as an alternative to design.
