III. Ecosmos: A Revolutionary Fertile, Habitable, Solar-Bioplanet Lifescape

A. Our Whole Scale EcosmoVerse Description Project

After theoretical Quantum Cosmology, here we present a survey of astrophysical vistas that have expanded from Galileo’s moon to an infinite multiUniVerse. Our “own” cosmos in its temporal course is graced by a trillion galaxies, each with billions of stars and a quintillion orbital worlds in and out of habitable zones. A good recent example is Finding Our Place in the Universe by Helene Courtois.

2020: Two decades in, an international collaborative astronomy by way of land-based and satellite telescopes, sophisticated instrumentation, analytic techniques, computational displays and more, has allowed we Earthlings to fill in and flesh out the temporal formation of a trillion galaxy, sextillion star spacescape. A prime aspect noted in Universal Evolution is a widest stochastic, contingent variety. We will enter its newly found occasion of myraid habitable planetary zones further on. Streaming 3D videos of intersecting galaxies and black holes, for example, can now inform and illustrate our awesome humankinder achievement, and future task of conceptual ecosmic self-description.

This is a 72 page International Astronomical Union document drafted by Debra Elmegreen, Ewine van Dishoeck, Renée Kraan-Korteweg and Piero Benvenuti to scope out a range of activities for new research projects and proposals, along with public and educational communication and engagement. Founded in 1919, the IAU publishes Symposia Proceedings of which the latest volume 353 is Galactic Dynamics in the Era of Large Surveys, see also Origins: From the Protosun to the First Steps of Life (345).

The International Astronomical Union, whose mission is to promote and safeguard astronomy in all its aspects through international cooperation, has been the worldwide organisation of professional astronomers since 1919. In the last century, the endeavour of astronomy has grown and evolved in ways that could not have been anticipated or predicted at the time of the IAU’s founding. In the early 1900s, astronomers had not yet proven that there were other galaxies besides the Milky Way. The expansion of the Universe was unknown IAU Strategic Plan 2020 –2030. (8)

Now, a century later, we know that the Universe is teeming with planets beyond our Solar System; thousands have already been discovered. Supermassive black holes reside in the centres of massive galaxies, and manifest themselves as quasars in the early Universe. Nucleosynthesis is understood to fuel stars. The accelerating Universe is filled with dark energy and dark matter, and the baryonic matter of which we are made. Gravitational waves reach us following black hole and neutron star mergers. We are poised to be able to answer the age-old questions of our place in the Universe and whether or not we are alone. (9)

Ambjorn, Jan, et al. The Self-Organizing de Sitter Universe. International Journal of Modern Physics D. 17/2515, 2009. This paper by Ambjorn, Niels Bohr Institute, Jerzy Jurkiewicz, Jagellonian University, and Renate Loll, Utrecht University, is also available at arXiv:0806.0397. It is introduced by saying that the 1917 cosmological solution to Einstein’s field equations by the Dutch astronomer Willem de Sitter continues to guide understandings of the nature of spacetime. (See also the author’s paper “Nonperturbative Quantum Gravity” in Physics Reports, online May 2012). Highly technical physics, (many more by each scientist at arXiv), as self-similar fractal’s appear to span from quantum to quasar.

We propose a theory of quantum gravity which formulates the quantum theory as a nonperturbative path integral, where each spacetime history appears with the weight exp (iSEH), with SEH the Einstein-Hilbert action of the corresponding causal geometry. The path integral is diffeomorphism-invariant (only geometries appear) and background-independent. The theory can be investigated by computer simulations, which show that a de Sitter universe emerges on large scales. This emergence is of an entropic, self-organizing nature, with the weight of the Einstein-Hilbert action playing a minor role. Also the quantum fluctuations around this de Sitter universe can be studied quantitatively and remain small until one gets close to the Planck scale. The structures found to describe Planckscale gravity are reminiscent of certain aspects of condensed-matter systems. (Abstract, 2515)

Borrowing a terminology from statistical and complex systems, we are dealing with a typical case of “self-organization”, a process where a system of a large number of microscopic constituents with certain properties and mutual interactions exhibits a collective behaviour, which gives rise to a new, coherent structure on a macroscopic scale.3 What is particularly striking in our case is the recovery of a de Sitter universe, a maximally symmetric space, despite the fact that no symmetry assumptions were ever put into the path integral and we are employing a proper-time slicing [11], which naively might have broken spacetime covariance. There clearly is much to be learned from this novel way of looking at quantum gravity! (2519)

Ambjorn, Jan, et al. The Self-Organizing Quantum Universe. Scientific American. July, 2008. A popular article on a breakthrough conception that fittingly comes by way of Jan Ambjorn at the Neils Bohr Institute in Copenhagen, Jerzy Jurkiewicz from Jagiellonian University in Kracow, Poland, and Renate Loll with Gerald t’Hooft’s Institute of Theoretical Physics at Utrecht University. Braced by a history of quantum theory, with over ten years of technical papers accessible from the author’s websites, what is proposed is indeed a cosmic Copernican Revolution. The 20th century stringy models, inappropriate and signifying nothing, ought to be set aside. Rather a material nature graced everywhere by component ‘motes’ in relational motion reveals an innate propensity to organize and develop itself into increasingly complex phenomenal form. A fractal-like spacetime thus abides whereof the same creative patterns and processes repeat at each sequential scale and instance. Quite Nobel quality work, and if properly grasped, a profound genesis universe can begin to gain its theoretical explanation.

To put it differently, if we think of empty spacetime as some immaterial substance, consisting of a very large number of minute, structureless pieces, and if we then let these microscopic building blocks interact with one another according to simple rules dictated by gravity and quantum theory, they will spontaneously arrange themselves into a whole that in many ways looks like the observed universe. (43) Similar mechanisms of self-assembly and self-organization occur across physics, biology and other fields of science. A beautiful example is the behavior of large flocks of birds, such as European starlings. Individual birds interact only with a small number of nearby birds; no leader tells them what to do. Yet the flock still forms and moves as a whole. The flock possesses collective, or emergent, properties that are not obvious in each bird's behavior. (43)

The insensitivity to a variety of small-scale details also goes under the name of "universality." It is a well-known phenomenon in statistical mechanics, the study of molecular motion in gases and fluids; these substances behave much the same whatever their detailed composition is. Universality is associated with properties of systems of many interacting parts and shows up on a scale much larger than that of the individual constituents. The analogous statement for a flock of starlings is that the color, size, wingspan and age of individual birds are completely irrelevant in determining the flying behavior of the flock as a whole.

An update on the growing acceptance, percolation, even acquiescence, unto a scientific mindset (e.g., Alvin Toffler in the May/June 2009 Foreign Policy) of a multiverse infinity of cosmoses, of which our present universe is but a fleeting “random accident.” The aim of this bibliographic website is to document that such misconceived doom is wrong and destructive while in our midst a novel cosmic to human gestation is arising, if only we could altogether look for it.

A Carnegie Institution for Science, Washington public lecture to be given on June 25, 2019 by the esteemed Princeton University astrophysicist. The quote below glimpses the latest views on the whole scale composition of this awesome cosmos, which yet seems readily amenable to our human description.

Of what is the universe made? Not only is most of the matter in the universe dark and unconventional but, surprisingly, the major component of the universe may be "dark energy" — a form of energy that opposes the pull of gravity and causes the universe's expansion to accelerate. By combining recent observations of clusters and large-scale structures, distant supernovae, and the cosmic microwave background radiation, we find evidence for a universe comprised of 5 percent normal atomic matter, 20 percent non-atomic dark matter, and 75 percent "dark energy." The observations suggest a universe that is lightweight. With only 25 percent of its critical mass-density needed to halt the universal expansion, the universe will likely expand forever. Dr. Bahcall will discuss the observations of the dark side of the universe and their implications.

Within the broad Natural PhiloSophia purview of this resource site, we are invited to appreciate and recognize this phenomenal Earth capability and achievement of cosmic significance.

The grand challenges of contemporary fundamental physics - dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem - all involve gravity as a key component. And of all gravitational phenomena, black holes stand out in their elegant simplicity, while harbouring some of the most remarkable predictions of General Relativity: event horizons, singularities and ergoregions. The purpose of this work is to present a concise, yet comprehensive overview of the state of the art in the relevant fields of research, summarize important open problems, and lay out a roadmap for future progress.

Barrau, Aurelien. The Holographic Space-time and Black Hole Remnants as Dark Matter. arXiv:2201.06988. The author is a French physicist and philosopher engaged with astroparticles, black holes and cosmology, and is the director of the Grenoble Center for Theoretical Physics. Again we cite as a present example by one person of the infinite reach of our Earthuman scientific prowess as it delves, so it seems, into any dynamic process and scalar dimension.

The holographic space-time approach to inflation provides a well defined and self-contained framework to study the early universe. Based on a quasi-local quantum gravity generalizing string theory beyond AdS backgrounds, it addresses fundamental issues like the arrow of time and the entropy of the initial cosmological state. It may also provide a naturel explanation for dark matter in the form of primordial black holes. This possibility is investigated and paths for observational confirmation are pointed out.
