The whole point of FTA is no, this is not the case. Most collapse in moments, or expand in short order into heat death, or cloud of non-interacting radiation, all without building anything useful such as matter from which other stuff can be formed.
Your assertion suggests that universe with different tunings form different observers, kind of like what might evolve on a different planet, or even Earth with one electron difference in the early days. This is not the case, but it was kind of the case when the original FTA argument noted the fine tuning of Earth. The rebuttal was the same one: there’s more than one planet, something not presumed back then.
That view kind of reflects human biases: They always make their universe as small as possible and resist any suggestion that there’s more, leading to geocentrism and even more localized models. Every time they put a fence around the world, it eventually gets demonstrated to be bigger.
So no, I would not be able to get behind a model with some rock bottom brute fact layer that restricts that which is from that which isn’t.
I don’t think you understood my words at all if you think that simple disclaimer is in any way a premise of FTA, implied or otherwise. FTA concludes that this universe has preferred ontology over the other ones, so that disclaimer as a premise would directly contradict what the argument is trying to demonstrate.
There are more than 2 multiverse hypotheses
Greene counted at least 9, so I agree that if you’re referencing ‘the multiverse hypothesis’, you need to specify which one.
A multiverse rebuttal is a good reason to reject the FTA, but it leaves the theist with the option of “agreeing to disagree”.
Sure, just as Darwin left the theists with that option, which some still take. Darwin had evidence on his side, as do all the multiverse hypotheses. Question is, where is the evidence (in each of the 9 cases) that the hypothesis is false? For some of the 9, I think the evidence (of it being false) is there, but for most, probably not. String theory is responsible for some, and since the ‘theory’ seems to produce nothing testable, the evidence ‘for’ is thin. For others like MWI, the evidence is raw simplicity over the crazy complications the other interpretations require to avoid that kind of multiverse.
I’m not an MWI fan, but it’s not the multiple worlds that turns me away, it’s the realism. I have issues with realism, so I prefer a relational interpretation which doesn’t have those problems.
There are infinitely many type of things that do not exist because the universe that would have produced them did not win.
I actually have a big problem with the concept of any universe winning. My model is a big basket of lottery tickets, not one of which is purchased. There’s one winning ticket, but nothing that wins it.
