    The fine-tuning of the constants of nature, which seems required for the existence of stars and planets and certainly for life and mind, is a fascinating feature of our universe. But before grand metaphysical schemes are advanced by philosophers, theologians, and even scientists, proper understanding of the underlying assumptions and fundamental physics are needed.

    What people don't seem to often remember (including myself) is how complicated and detailed science gets at the nuts and bolts level. Think of a single cell. It has hundreds of components. And there are groups of researchers publishing peer reviewed papers on just one of those components, while others may be looking at how this one component interacts with another. That leaves hundreds of other components and interactions being researched by other groups of researchers reporting findings in what become thousands of peer reviewed papers. Etc. Theorists and philosophers have a tough job keeping up with all that, I imagine.

      They are discussing the fundamental physical processes that enable those particular cell components to even exist.
      Deeper down, why do the elementary particles even exist? Why do they then form protons, neutrons, and atoms?
      Our biochemistry doesn't occur without the structure of the periodic table of elements. Science doesn't know why those atoms exist, only that they do.
      You may say "Who cares?!" However, MRI machines only work due to the peculiar magnetic property of protons that is tough to explain. Why do all protons have the excact same magnetic moment, and why that particular value?
      I recently published a paper on this topic: "Ground state quantum vortex proton model" in Foundations of Physics on January 23, 2023.

      The subject of fine-tuning is more basic than the actual chemistry of life, though, isn't it? Fine-tuning has to do with the free parameters in the equations of physics that make chemistry possible in the first place. For example, before you can have chemistry, you first have to have a periodic table. To get a periodic table, you first have to have star formation. To get star formation, there are constants that have to fall within a certain range of values.
      I agree it's complicated at the nuts and bolts level, though. How do we know what a universe would look like if we tweaked the constants? There are so many equations of physics and so many free parameters, how can we possibly vary all the parameters through all the range of possible values of all the constants and solve each equation for every possible variation in order to construct a universe? We would need supercomputers to run simulations to be able to figure that out. Is anybody actually running these kinds of simulations?

      ... And I see a prokaryote in more simplistic terms. Amongst all of the many processes you've mentioned, I simply see a single-strand nucleoid encased within a protective outer shell. The nucleoid represents "life," and the capsule shell is what protects it from "death." I also see a prokaryote as an evolution of a hydrogen atom's single positively charged proton and negatively charged electron. In other words, "positive and negative" evolved into "life and death," respectively.
      To return to your point, we could be missing the forest from the trees by focusing more on all the components instead of what they represent as a whole.

    Another explanation for fine tuning is that a retrocausal, feedback-loop is present that is constantly at work around the wave function collapse. A massive number of probabilities are spun out but reality emerges as the retrocasual, feedback-loop fixes on a single reality with the best probability of sustainability.

Instead, a very large number of randomly distributed values such as location in the galaxy, star properties, orbital mechanics, planetary characteristics, and much more will essentially ensure that SOME will be suited for life..

    It's surprising that Lee Smolin's theory of Cosmological Natural Selection wasn't mentioned. Unlike the multiverse theory that Albert did mention, in which "eternal inflation" produces a huge number of universes with randomly selected fundamental constants, CNS doesn't need to appeal to the Anthropic Principle to explain how we're lucky enough to find ourselves in one of the tiny fraction of universes that are hospitable to life. According to CNS, (1) universes that are good at producing black holes have laws of physics and fundamental constants that are compatible with life as we know it, and (2) every black hole spawns another universe with laws & constants similar to (but not necessarily exactly the same as) the laws & constants of the universe in which the black hole was created. It then follows by the evolutionary principle of natural selection that, if at least one universe produces black holes, then eventually most universes will be good at making black holes, and compatible with life.

    • @fluffysheap

      It's a crackpot idea.
      1) There is no actual reason to believe that black holes spawn new universes. This is only speculation
      2) If black holes do spawn new universes, there's no mechanism for how they can keep the laws of physics mostly the same but not totally the same so that evolution could take place. Universes don't have DNA.
      3) Our universe does not really look like the inside of a black hole. In particular, it's not rotating. And the cosmological event horizon is not the same kind of thing as a black hole event horizon.
      4) Our universe is not actually extremely good at making black holes. It's just kind of so-so.
      5) There's not really any reason to think that life is more likely in universes with lots of black holes. It isn't hard to construct hypothetical universes that are better at making black holes but worse or impossible for life. And most of the fine tuning needed for life doesn't make black holes easier.
      6) You still need fine tuning because you have to assume some sort of progenitor universe that is capable of making black holes at all.
      It's just really not a sound theory. The only plausible explanations are multiverse and God. And there's more evidence for God.

    Of course it's possible some sort of life very different from life as we know it might be abundant throughout the universe but in this case there is no fine tuning; if life or mind very different from life as we know it is possible then in principle it could exist in any universe.

    Heavy metal fans love slicing the tops and bottoms off sine waves because the resulting sharp-edged waves produce a seeming infinity of screeching harmonics. A question, though: Are these harmonics real? What actually happens is you get a rattier wave that dissipates quicker and _sounds_ like a screeching infinity of noise when analyzed by a highly structured instrument, such as our inner ears, that splits that noise into a vast number of smaller, simpler, weaker waves. The original distorted wave remains what it always was: A single, messy wave.
    In physics, we similarly use carefully constructed material instruments - local xyzt coordinates composed of rulers and clocks - to make local sense of a wide range of decidedly odd matter and energy waves that always obey the rules of special relativity. These xyzt perception instruments work well if you keep everything local, medium-scale, and moving slowly, but guess what? If you presume to make one of these local-only xyzt interpreters more real than reality, such as by assuming it applies out to infinity, you end with the cosmic equivalent of heavy-metal screeching noises.
    Some folks like to call such collections of xyzt-created interpretation noises multiverses. Alas, as with heavy-metal screeches, these are illusions created by overextending one local beholder’s actual reach and importance. Einstein warned us about that in special relativity. Reality remains a single, messy wave whose full dynamics are never fully expressible using the xyzt instruments of one observer or some Hilbert-space infinity of similar observers. That’s all just noise. At the information level, for example, such waves interact using only the squares (e.g., year-lightyears) of what we think of as distances. That simple squaring maintains the Poincare symmetries while preventing causality violations within a fully _singular_ universe.
    Fine. So what does any of this have to do with fine-tuning?
    Quite a bit. In a universe where our usual metrics of distance, time, energy, and even that squared metric I just mentioned emerge _only_ in the presence of massive levels of causal information - history - the scary underlying metric is that everything happens _at once in one place,_ that is, with maximum space-time entanglement. What we think of as history emerges only as a consequence of interactions that create information and thus make distance and quantity metrics meaningful.
    It’s not some infinity of universes vying with each other for existence. It’s _one_ universe struggling with itself to convert boring, eternal self-erasure into a structure with limits, barriers, and _history._ That emergence implies hierarchies of existence, such as the absolute universality of Standard Model particles across the visible universe, that could care less about our local xyzt perceptions of space and time.
    Fine-tuning occurs in the middle range between the universality of Standard Model particles and the piece-by-piece, local-only emergence of the xyzt stability needed for life and consciousness to survive in narrow situations such as moderate planetary surfaces. While powerfully constrained by its emergence, this fine-tuning has never stopped.
    However, until we get out of heavy-metal mode and stop too-casually postulating infinities of this and proliferation of that, we’ll never understand these far more interesting regions of quite real and - you can bet - experimentally accessible physics. That middle ground is also the domain of answers to annoying questions such as why every time you wake up, you find yourself the same person you were the day before. In a universe where you, as an inertial-frame observer, are the main instrument for creating a local definition of space and time, you are necessarily more than just a bunch of atoms.

    Suppose that mass and charge spatially dissociate at very low energies, so that nucleon charge structure becomes massless. Also suppose that charge becomes smeared over surfaces and that mass energy behaves as confined vacuum energy.
    We can then construct models such as "Ground state quantum vortex proton model" published in Foundations of Physics on January 23, 2023.
    This model accurately explains the numerical relationships between proton mass, magnetic moment, and charge radius. It also provides a description of how valence quarks and a pion cloud can emerge at energies above the proton ground state.

      Unless this model gets rid of free parameters altogether, I don't see how it would avoid fine-tuning. I mean if you can unify three fields into one, the one field would still have to be fine-tuned, wouldn't it?

      ​​​​​@@philochristos Excellent question! Suppose we eventually find relationships between all the physical constants, leaving just one "adjustable" parameter.
      It is likely that one lone parameter will have a very narrow range of values where matter can exist. Can potential universes, where matter can't exist, themselves exist?
      In other words, is a matter-free universe actually a universe or merely part of the void beyond our Universe? The void from which our Universe appeared to materialize with an excess of matter over antimatter and a favored chirality (which may be linked).

    In our greedy desire to be like God, we left Heaven to find the knowledge that God has forbidden despite His warning that there is only suffering beyond Heaven. We lost faith in God's love and did not heed. We ended in cold dark emptiness instead. We created our hell by choice.
    Earth is our chance to override our prior bad choice, so to return Home, by regaining our faith in God's love by choice. Yet some of you still want to find this forbidden knowledge to be like God. You are always free to choose hell, God can not force you Home.

    Fine Tuning is nonexistent because adapted to the physics of the Universe. The problem is the misunderstanding of the laws of physics. The laws of physics are not proscriptive where they prohibit the Universe from doing something they are descriptive where they describe on average what we observe.

    Regardless of multiverse theories, I don't find the argument that out universe is fine tuned for life at all convincing. It's plainly nothing of the sort. Look at the universe, at 93 billion lightyears across (allowing for expansion) it's almost entirely hard vacuum that would kill any of us in a few seconds. The rest is mostly blazing hot stars, searing clouds of gas or crushing black holes and neutron stars. Many of these emit mind bogglingly powerful jets of radiation and plasma capable of sterilising whole galaxies. Even ordinary stars like our sun eventually burn out or explode violently. When you get down to planets like ours, without the unlikely accident of a large moon, the Earth would have a crushingly dense atmosphere and blastingly hot surface temperatures much like Venus. Life here has been almost entirely wiped out by asteroid impacts multiple times. We're extraordinarily lucky to hold on to this infinitesimally tiny toe hold of life in an unremittingly hostile universe, and will probably do so only briefly on cosmic scales. We could all be wiped out in an instant, and eventually we almost certainly will be. Fine tuned my posterior. We're like a bunch of rich passengers on the Titanic chatting about how wonderful this ship is, while surrounded by an iceberg filled ocean of freezing water. One day we're going to hit one of those icebergs and there's probably nothing we can do about it.

      In other words, the universe wasn't necessarily fine-tuned for life. It was only fine-tuned for a "sustainable existence" at the time of its emergence. As with my own existence, the universe had no idea what it would eventually evolve into ... _until it got there!_

    The idea that an *infinite number of universes* can explain the fine-tuning issue is just as far-fetched as suggesting that an omniscient God orchestrated this *single finite universe.* Actually, these two _extreme_ explanations merely represent opposite ends of the "spectrum of possible answers." What nobody seems to want to consider is that the answer may lie somewhere in between:
    *Third Option:* This single finite universe was orchestrated by the absolute minimum amount of intelligence necessary to sustain it and nothing more. This core intelligence continuously evolves in direct correlation with the amount of complexity that emerges in the universe. Fast forward 13.8 billion years and you now have the highest-known level of intelligence (humans) trying to figure out how it all got started.
    This option would explain a fine-tuned universe, the emergence of life and self-awareness, but nobody really wants to consider this because science's Multiverse and religion's God are far more "exciting" answers.

      The minimal amount of intelligence needed is an interesting idea; although as I've mentioned in another post, _"intelligence"_ is a word loaded with meaning. May I ask how you define intelligence in this context? For example, is there a component of "intent" or even "free will" to this intelligence or is something else involved? Nietzsche, for example, I think would say, it's all about _will to power_ and how everything seems to accumulate power to itself in a move toward stability, survival, growth and even flourishing. But I would ask Nietzsche the same question if I could: does will to power include intent? or is something else involved?

      ... "Logical Orchestration," that's how. And if this intelligence is in direct proportion to the amount of complexity involved, then wherever existence is found, you'll find an amount of intelligence commensurate to the amount of complexity.
      Consider that for anything to exist it must first be *logically conceivable,* correct? So, if that's the case, then does logic predate existence or are they two sides of the same coin and emerge together?

      So, if you rewind the universe back to Big Bang, what we call "intent" would be a minimalistic drive to push forward.

      It's just hard for us to imagine it existing in such simplistic terms.

One of them would be: whatever one wants to call it -- intelligence, self-organizing principle, will to power -- where did this thing come from that seems to seek to organize matter in certain ways or in a certain direction? Is it just the "inclination" of something that blew apart trying to find its way back again and in the process creating a whole bunch of new previously unknown stuff like us? Or is it a product of some teleological factor, like with Hegel, in which the universe, through a series of ideas and experiences, is trying to understand itself.
