How is that a good theory? Which falsifyable predictions does it produce?

All it takes What is a "real physical world"? The theories don't make that particular distinction.

The only infinities appear in some theories, and are more a problem of the particular theories than that of the underlying reality. E.g. infinite spacetime curvature singularities go away in a number of TOE candidates. > generate the mathematical Plenitude. How can you prove that the Moon is not made from green gorgonzola, when we're not looking?
You're a hard positivist. There's nothing really wrong with that: if we had to choose between killing all the scientists and killing all the metaphysicians, killing the metaphysicians would be the better option. Nevertheless, I think it's interesting to speculate on such unfalsifiable ideas as the interpretation of quantum mechanics and multiverse theories, and such speculation may guide future scientific work. After all, the verifiability/ falsifiability principle is *itself* metaphysics by its own criterion.
