A0. The pivotal fine tuning beneath !! Gemini claims that the absence of a speed limit ‘would likely result in a "causal soup" where no stable structure could ever form’ in the first place, thus a lifeless cosmos : see https://gemini.google.com/app/66a05730b0178d25 ? Among scholars who debate the universe’s fine-tuning for life, has any argued that life depends on a universal speed limit, whether on the presence of such a limit, or on its particular value (at 3×10⁸ m/s)? ! consensus on both counts: already it’s considered part of the fine-tuning for basic life, viz. its creation and stability on the short scale of time : see https://gemini.google.com/app/a15855dddec6eca0 surprise, still the following surprise me • | support for the stability and survival of intelligent life in long-term cosmic time, its very presence (surprise!) - this is the basic surprise / though it breaks [out of] the context of Geminini’s claim - the other instances of surprise are drill-down details that reveal the persistence — the stubborn resistance to explanatory mitigation — of this basic surprise ∴ the present project conflates and intertangles two projects: A. claim of [in-built] highly-fit cosmic support for long-term stability and survival / its very presence B. enquiry into the aetiology of {that support} / why is it there? - they’ve been interfering with each other, causing me confusion divide+ this project accordingly : private : Seeking prior work on base topic A: ‘Locate any academic work or other scholarship on this topic: the presence in the cosmos of an integral safehold optimal for protecting and preserving intelligent life over the long term. Its main component is the speed limit (c) on causation. It affords interstellar diasporas with protection from existential hazards — especially those of their own making, such as war and pollution.’ : see https://www.perplexity.ai/search/5febbdb5-503b-4df4-b7bb-e3c925cb9597 : none found : see https://gemini.google.com/app/4ab49ea749b4276c : none found | that a tuning for the creation and stability of basic life in short-term geogenic time would happen also (surprise!) to cover the stability and survival of intelligent life in long-term cosmic time - that the latter would need no tuning *of its own* to accomplish, but simply come *built in* to the former ∵ most current explanations for fine-tuning cannot account for it ∵ multiverse theory (maybe the consensus explanation for fine-tuning, at least among physicists) cannot account for it : see `sticks out as surprising, inexplicable by that theory` @ I6.multiverse_ensemble_theory.brec ∵ observer selection effects cannot account for it : see I2.observer_selection_effect.brec • that a speed limit so obviously crucial to intelligent life in long-term cosmic time would (surprise!) be crucial also to basic life in short-term geogenic time, making the latter surprisingly sensitive (in retrospect) to its presence and value : ad `crucial to intelligent life.+cosmic time` : its stability and survival, that is : ad `crucial.+to basic life.+geogenic time` : its creation and stability, that is / the need isn’t so obvious in the latter case explanation: mitigating the surprise by way of | a speed limit is necessary to long-term tuning, but dispensible for short-term tuning - the otherwise surprising sensitivity of the short-term tuning to the speed limit can be explained thus: • the short-term tuning is part of a long-term tuning - creation and survival of basic life over the short term is, after all, necessary to the survival of intelligent life over the long term - one cannot have the latter without the former ∴ tuning for the former is proper to the latter ∴ the presence of long-term tuning suffices in itself to explain what otherwise would be surprising - further still, on all cosmic properties taken together - the argument appears able to bear their weight ∵ hard to conceive a different (let alone better) long-term tuning ∵ hard to conceive that any of these properties could be dispensed with ∵ hard to conceive (especially) that intelligent life could be preserved|protected from itself by anything other than the most general of safeguards, namely a limit [absolute] on causation [itself] - we [just] too cunning and persistent in overcoming obstacles ∵ easy to conceive a different (maybe even a better) short-term tuning : re `maybe even.+better` see e.g. https://plato.stanford.edu/entries/fine-tuning/#CondRealFineTuneForLife : ‘If Adams is right, our universe may just be garden-variety habitable rather than maximally life-supporting.’ ∵ easy to conceive of ways of safeguarding|shielding the formation of complex structure (such as that of basic life) other than a general limit on causation | the tuning for life’s long-term survival is (somehow) more basic - it is (in some sense) prior to the short-term tuning (for creation and stability) ∴ the short-term tuning {builds|is built} *on top* of and/or *around* the long-term ∴ the short-term tuning is made sensitive to (changes in) that of the long-term - minor changes in the basic, prior long-term tuning on/around which the short is built are likely to de-stabilize the short ∴ the short-term tuning’s sensitivity to the speed limit (to its presence and particular value) is a mere artifact of the long-term tuning • the tuning is effected by tuning mechanism or mode that is (somehow) directed toward life’s long-term survival • the tuning is effected by a designer who purposes the long-term survival of [intelligent] life’s / viz. not by multiverse theory, nor by an observer selection effect
