It’s not clear that massive evidence for fine-tuning of the universe makes much difference to most naturalists because it just increases their certainty that the zero-evidence multiverse must be out there. But the rest of us will learn something. Come to think of it, panpsychists might adopt fine-tuning as an argument for an intelligent universe. We shall see.
A good deal of effort goes into explaining away the fine-tuning of our universe and our Earth for life. But note the intellectually disastrous theses that are casually accepted as alternatives. What if we just accepted it? The way we accept the significance of 1/137.
