Re: [asa] Stars May Not Be So Fine Tuned After All

The fact is that multiverses is a logical outcome and prediction of
the various cosmological models involved. (Level I: (Open multiverse)
A generic prediction of cosmic inflation is an infinite ergodic
universe, which, being infinite, must contain Hubble volumes realizing
all initial conditions.) This by itself does not guarantee the
existence of multiverses, however it provides at least a theoretical
foundation. The problem is that presently multiverses remain beyond
'observation' and 'testing'.
