Fine tuning Intelligent Design Multiverse

Molecular geneticist asks: “Does the existence of a multiverse hold the key for why nature’s laws seem so simple?”

Life is Simple

His latest book is Life Is Simple (2021), in which he proposes that universes evolve in a Darwinian process, which “solves” the fine-tuning “problem”:

In my latest book, I propose a radical, if speculative, solution for why the Universe might in fact be as simple as it’s possible to be. Its starting point is the remarkable theory of cosmological natural selection (CNS) proposed by the physicist Lee Smolin. CNS proposes that, just like living creatures, universes have evolved through a cosmological process, analogous to natural selection …

[Lee] Smolin came up with CNS as a potential solution to what’s called the fine-tuning problem: how the fundamental constants and parameters, such as the masses of the fundamental particles or the charge of an electron, got to be the precise values needed for the creation of matter, stars, planets and life. CNS first notes the apparent symmetry between the Big Bang, in which stars and particles were spewed out of a dimensionless point at the birth of our Universe, and the Big Crunch, the scenario for the end of our Universe when a supermassive black hole swallows up stars and particles before vanishing back into a dimensionless point. This symmetry has led many cosmologists to propose that black holes in our Universe might be the ‘other side’ of Big Bangs of other universes, expanding elsewhere. In this scenario, time did not begin at the Big Bang, but continues backwards through to the death of its parent universe in a Big Crunch, through to its birth from a black hole, and so on, stretching backward in time, potentially into infinity. Not only that but, since our region of the Universe is filled with an estimated 100 billion supermassive black holes, Smolin proposes that each is the progenitor of one of 100 billion universes that have descended from our own.

The model Smolin proposed includes a kind of universal self-replication process, with black holes acting as reproductive cells. The next ingredient is heredity. Smolin proposes that each offspring universe inherits almost the same fundamental constants of its parent. The ‘almost’ is there because Smolin suggests that, in a process analogous to mutation, their values are tweaked as they pass through a black hole, so baby universes become slightly different from their parent. Lastly, he imagines a kind of cosmological ecosystem in which universes compete for matter and energy. Gradually, over a great many cosmological generations, the multiverse of universes would become dominated by the fittest and most fecund universes, through their possession of those rare values of the fundamental constants that maximise black holes, and thereby generate the maximum number of descendant universes.

Johnjoe McFadden, “Why simplicity works” at Aeon (October 11, 2021)

One difference that we might note between this thesis and the sort of thing we read in biology journals is that there is evidence for the existence of countless life forms, whether or not their journey through time is explained by Darwinism. There is no evidence of any universe other than our own. That’s why some of us think of the multiverse as science’s assisted suicide.

You may also wish to read: In an infinity of universes, countless ones are run by cats… Daniel Díaz notes that most of the talk about the multiverse started to appear once it was realized that there was fine-tuning in nature.
Robert J. Marks points out that even 10 to the 1000th power of universes would only permit 3,322 different paths. Infinity is required but unprovable.

    The thing is simplicity doesn’t always work
    I mean the whole concept of it Ochman’s razor has been abused over and over again and it has led to dead ends to it didn’t unlock the universe just gave them a point of reference to start measuring things

    That alone makes me disregard this guys opinion altogether

    Oh and there’s that catch all natural selection naturally selected (whatever) to exist naturally

    The ability to evolve a toaster (but doesn’t) it’ll evolve universes too (and magically does)

    You can use the logic of natural selection to make anything come into existence

    Natural selection and God to be interchanged

    Furthermore why those rare values important and selected for? Is it because they assume they are stable? just because they’re important to life doesn’t mean that they’re important to anything else. The rare values could be completely destroyed by a myriad of other values and one giant cosmological black hole would send us all back into a big crunch, destroying the whole damn thing! Somehow none of these universes interact with our own cuz magic I mean science, science caused all of this

    This is an absurd concept, even on the surface.
    “he imagines a kind of cosmological ecosystem”, so the book is essentially one big imaginative exercise? What process, other than a Mind, could do the selection among universes?
    Also, there would be many universes in which the laws of physics would not allow for black holes to exist – hence extinction of that line? Perhaps that is his “natural selection”? Most of his universes fail to reproduce, thereby narrowing the spectrum of possibilities. But as Aaron says, why – without a Mind – would the Universe generating scheme select for complex, finely tune for life, Universes?
    Even the title is silly; life is anything but “simple” as he should know.
