Circumstellar Habitable Zone - Ecobalance - Ecosphere
The evolving physics that define the vast array of coincidetally balanced, "just-right" conditions that make up the Goldilocks Enigma, ranges dramatically in magnitude and time, from the near-"flat", balanced structuring of the universe, itself, all the way down to our own local self-regulating ecobalance, whose chaotic cycles we directly contribute to enhance over time. These "ecospheres" began unfolding at the moment of the big bang, but it took most of 14 billion years to bring them all to "fruition", so claims that this structure defining physics isn't **necessarily** pointed directly at carbon based life, are, at least *apparently* absurd, and must be justified with something more than "somewhat" established cutting-edge physics speculations.
The relevant anthropic physics isn't strictly geocentric, however, because the same conditions also apply to other galaxy systems that are similarly evolved, time and location-wise, as ours is:
The Goldilocks Enigma constrains the parameters to a balance of extremes... so it only applies to the ecosphere of galaxies that formed on the same evolutionary time/location "plane" as we did. Planets orbiting stars in galaxies that are too old or too new, too large or too small, do not fit the "coincidentally balanced" nature as the average of extremes... etc... etc... ect... all the way down to the local ecobalances of the ones that do, and life will only arise on planets in galaxies, (and universes), where ALL of the anthropic coincidences are simultaneously in effect.
The "cosmological principle" derives a "mediocre" a priori statistical distribution of values of observables, but this is not what is observed and is the reason for the anthropic physics that defines the "Goldilocks Enigma", so the combined effect of the cosmological principle with the goldilocks constraint extends to the observed universe to produce a biocentric cosmological principle.
This also addresses the alleged, Fermi "Paradox", as well, since we should not *yet* expect to hear from similarly developed intelligent life, because their radio transmissions have not had time to reach us... *yet*... either.
That's a testable prediction about where and when life will most likely be found elsewhere in the universe.
This paper by A. Feoli, and S. Rampone, further discusses this in context with similarly developed systems, but they fail to take the balance of extremes that defines the "Goldilocks Enigma" into account here, because they apply the mediocrity principle, instead, so their formula and anthropic statement are not quite accurately inserted into their large scale equation, as would be the case if they'd considered the entire set of anthropic balance points that evolve, so their solution and anthropic statement are generalized and overstated, rather than being specific and pointed toward a fine layer of similarly evolved galaxies, stars, and planets:
"Is the Strong Anthropic Principle Too Weak?"
We discuss the Carter's formula about the mankind evolution probability following the derivation proposed by Barrow and Tipler. We stress the relation between the existence of billions of galaxies and the evolution of at least one intelligent life, whose living time is not trivial, all over the Universe. We show that the existence probability and the lifetime of a civilization depend not only on the evolutionary critical steps, but also on the number of places where the life can arise. In the light of these results, we propose a stronger version of Anthropic Principle.
When you apply the Goldilocks Enigma, rather than the mediocrity principle, then a much more accurate and testable formula falls-out along with a more accurate statement about a strong biocentric principle, so this "coincidental" Enigma extends to include every similarly evolved galaxy that exists in the same common "layer" of galaxies as we do. The average of extreme opposing runaway tendencies that are common to the anthropic coincidences make many testable predictions about the observed universe.
Like, life, (past or present), will not be found on Mars nor Venus, but it will be found in other galaxy systems along the layer of spacetime that makes-up the goldilocks enigma. Venus suffers from the runaway greenhouse effect, whereas Mars represents the cold stagnate proof of what will happen if extremist environmentalists get things all their way too, so heed the lesson of this anthropic coincidence.
