The Everett MW is a different kind of multiverse, separated by something other than space, where they peel off from this reality into new ones. Don't like it, never have.
Yeah, but isn’t the
MWI a prime example of how total nonsense can be inferred from the maths?
In which case (and just out of curiosity), why don’t you like what the maths have to say about multiple worlds from the perspective of Everett’s theory, but seem to have no issue with what the maths have to say about multiple worlds from the perspective of string theory?
It's true that math can create both real and unreal models.
However, it a mischaracterisation to say that the Everrett interpretation came from the math. In truth, it's a way of trying to explain observation effects of the double slit experiment. I think it is fanciful but, reality is so bizarre, I wouldn't even rule that out.

Let’s get something straight. I do not think that the existence of 10^500 other universes is preposterous (in truth, to me that number is too small).
However, what I do think is preposterous (as I mentioned earlier) is that just to avoid any hint of intelligence being involved in the creation of our universe, some humans are willing to accept theories that are infinitely worse in terms of logic and plausibility.
Yeah, yeah, I know – “...but it’s all there in the maths...”
But like I said, the maths also lend credence to the Everettian codswallop.
The multiverse actually is mathematically based rather than a way of explaining away a counter intuitive problem.

...but also how it (the “sprouted” seed) managed to self-arrange its constituents into a state of order that defies our comprehension.
Yet the proponents of certain multiverse theories simply want to compound that mystery by applying it to a near infinity of other “seeds” (most of which are duds according to the theories)...
Most of them would be - perhaps. Very early days yet. Don't treat speculative guesses as theories. None of these things we are discussion are theories, just hypotheses.

That is because they don't know. We have one example of life that, so far, has had only a trifling influence on the solar system, let alone the galaxy or the universe. The potentials are huge but the actuality - that which we can be certain about - is tiny, and there would need to be evidence of tangible effects of life on cosmology and on the very nature of physics before life can be plugged into such equations.
seeds wrote: ↑Thu Oct 25, 2018 2:55 amIn other words, the maths are thoroughly blinkered when it comes to factoring-in the most important aspect of reality (again, the essence of life) – an aspect that would render all of reality completely meaningless if it were missing.
However, no one lives their lives by the math. Because science has caused complications for theistic thought over centuries, believers tend to see this as religion v science. However, physics is not competing. It's not at all about the meaning of life, but its results are suggestive of likelihoods and possibilities. Physics is a study of how physical systems work with an attempt to achieve predictive capacities.
IMO if you seek a deeper understanding of reality, you need to range well beyond physics and the other natural sciences, but you ignore physics, biochemistry, biology, geology and cosmology at your peril. Each is a different texture in the fabric of reality.

You wonder how universes without "stars, planets, and life" can qualify to be called a "universe''. No true Scotsman wears a chastity belt under his kilt. No true universe exists without stars, planets and life?
However, "stars, planets and life" make up approximate 5% of the universe.There most certainly could be universes consisting only of the majority "dark stuff" that's in our universe, with molecular clouds in conditions that don't allow atoms or other emergent phenomena to form. Also note that for about 300,000 years our universe had no celestial bodies or, obviously, life, but it was still a universe.
Just to highlight the problem of your downplaying of life’s role in the context of reality...
...imagine a situation where all of the universes, and all of the stars and planets, and all of the “dark stuff,” and all of the molecular clouds, etc., are all gathered together into one location, and then give me a single visualizable scenario where any of it would have any reason or purpose whatsoever for existing if life and consciousness did not exist to confer meaning on it.
I cannot speak for others but, as far as I know, I never had a reason for existing. However, the conditions were right that an entity such as me could exist, as opposed to your example of a collapsed universe.
Just as atoms played no part in the first 300,000 years of the universe until they emerged, life seems to have played precious little part in the subsequent period (unless there are some thrilling discoveries awaiting us).
