A fined tuned argument.....Heywood style.

[Heywood]

What good is a paper that makes a prediction using a theory that can predict anything?

Now you're being silly, their theory can predict something. Just by saying "multiverse" without saying anything further, of course you can't predict anything, but that's your problem. One has to be more specific what one means.

What are they predicting? That some universes are going to be in the metastability region?

Also I edited my last post while you were responding to it.
