Addendum on Emergent Complexity
2 February 2016
This post is intended as a quick addendum to my post The Apotheosis of Emergent Complexity, in which I considered, in turn, the respective peaks of star formation, life, and civilization during the Stelliferous Era, as exemplifying significant forms of emergent complexity in the universe.
The apotheosis of emergent complexity recognized in that earlier post — when stars, life, and civilization are all represented — can be further narrowed in scope beyond the parameters I previously set. With the sole examples of ourselves as representing life and civilization, we can acknowledge a minimal form of the apotheosis of emergent complexity already extant, and as long as our civilization endures and continues in development it retains the possibility of seeing further emergent complexities arise. Among the further emergent complexities that could arise from terrestrial life and civilization is the possibility of this life and civilization expanding to other worlds. A simple expansion would represent the spatial and temporal extension of emergent complexity, but life and civilization almost certainly will be changed by their adaptation to other worlds, and this adaptive radiation on a cosmological scale may involve the emergence of further emergent complexity (in which case a fourth peak would need to be defined beyond stars, life, and civilization).
An expansion of terrestrial life and civilization into the universe that constitutes an adaptive radiation on a cosmological scale, is an event that I have called the Great Voluntaristic Divergence (in Transhumanism and Adaptive Radiation) — “great” because it takes place on a cosmological scale that dwarfs known adaptive radiations on Earth by many orders of magnitude, “voluntaristic” because both the direction and the nature of the radiation and the adaptation will be a function of conscious and intelligent choice, and “divergence” because different choices will lead to the realization of diverse forms of life and civilization not existing, and not possible, on Earth alone. We can think of the Great Voluntaristic Divergence as a “forcing” event for the principle of plenitude. I have noted previously that cosmology is the principle of plenitude teaching by example. When the principle of plenitude works at the scale of the cosmos and at the level of complexity of civilization, further emergent complexity may yet transform the universe.
If we take the peak of emergent complexity as beginning with the Great Voluntaristic Divergence, this peak of emergent complexity so conceived will end with the End Stelliferous Mass Extinction Event (which I first formulated in my Centauri Dreams post Who will read the Encyclopedia Galactica?). Once star formation ceases, the remaining stars will burn out one by one, and, as they wink out, the planetary surfaces on which they have been incubating life and civilizations will go dark. Any life or civilization that survives the coming darkness of the Degenerate Era, the Black Hole Era, and the Dark Era, will have to derive its energy flows from some source other than stellar energy flux concentrated on planetary surfaces, which I noted in my previous post, Civilizations of Planetary Endemism, typify the origins of civilizations during the Stelliferous Era.
If life and civilization endure for so long as to confront the end of the Stelliferous Era, there will be plenty of time to prepare for alternative methods of harnessing energy flows. Moreover, I strongly suspect that the developmental course of advanced civilizations — the only kind of civilizations that could so endure — will experience demographic changes that will bring populations into equilibrium with their energy environment, much as we have seen birth rates plummet in advanced industrialized civilizations where scientific medicine reduces infant mortality, lengthens life, and increases the costs of child-rearing. When the End Stelliferous Mass Extinction Event is visited upon our distant descendants and their successor institution to civilization, their horizons will already have been altered to accommodate the change.
