The first is inflationary cosmology; the second is quantum mechanics.  Though very different, these two multiverse models share two features: first, they both posit objective physical probabilities that tell us how likely we are to b … [Read more...]

First, I will argue that his considerations are only correct, if at all, for a limited set of multiverses that have particular features. As a result, I will argue that his claim cannot be generalised as a statement about all multiverses. This failure to generalise, I will argue, is also a … [Read more...]
