Paul Davies goes a long way towards suggesting that he believes the creation of life to be somehow the 'goal' of the universe without suggesting that it is the work of a higher intelligence or God. That is to say he tends towards the belief that the principle of life 'builds purpose into the workings of the cosmos at a fundamental (rather than an incidental) level, without positing an unexplained pre-existing purposive agent to inject purpose miraculously.' This belief is his tentative solution to the 'Goldilocks Enigma', the 'reason' why planets such as our own are 'not too hot and not too cold but just right'.
The evolutionary physics that defines the "just-right" conditions for the goldilocks constraint applies to other systems that are similarly developed, time and location-wise, as ours is:
The goldilocks enigma constrains the parameters to a balance of extremes... so it only applies to 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:
This also resolves 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.
Um... just an FYI, but 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 the Drake Equation, as would be the case if they'd considered the entire set of anthropic balance points that evolve, (time and location-wise), from the observed, nearly-balanced stucture of the universe itself, all the way down to our own local ecobalance... so their solution and anthropic statement are dramatically 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.
... and uh... when you apply the Goldilocks Enigma, rather than the mediocrity principle, to the Drake Equation, then a much more accurate and testable formula falls-out along with a more accurate statement about a strong biocentric principle... just in case nobody noticed.
Peter Woit made the following statement in the comments section of his "rewiew" of Davies' book, and it is important as it applies to this thread, so I'm bringing it in now:
The “principle of mediocrity”, or more generally, the use of a multiverse model that gives an a priori statistical distribution of values of observables, combined with the anthropic principle as a selection effect, can in certain cases give predictions.
As this applies to our obseverd universe.
The "cosmological principle" gives a "mediocre" multiverse-"like" 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... defines a Biocentric Cosmological Principle.
The average of extreme opposing runaway tendencies that are common to the anthropic coincidences make many testable predictions about the observed universe.
Like, life will not be found on Mars or Venus, but it will be found in other systems that meet the goldilocks criterion.
'Read em, and weep'... where "weep" is like a code-word to anticentrists to willfully ignore the hard evidence.
