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

B. Our Whole Scale EcosmoVerse Description Project

Bahcall, Neta. The Dark Side of the Universe. carnegiescience.edu/events/lectures/dark-side-universe. 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.

Barack, Leor, et al. Black Holes, Gravitational Waves and Fundamental Physics. Classical and Quantum Gravity. 36/143001, 2019. We cite this entry among many as an example of today’s Earhtwise collaborative, multi-author (some 200 here) research projects as they proceed apace with humankinder’s self-quantitative discovery of a genesis uniVerse. The 272 page document is posted as 1806.05195 on the arXiv eprint site, search Samaya Nissanke among names for follow up studies such as A Unique Multi-Messenger Signal of QCD Axion Dark Matter (1905.04686). 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.

Baugh, C. M. A Primer on Hierarchical Galaxy Formation. Reports on Progress in Physics. 69/12, 2006. Along with the Mekjian paper below, a report that interstellar reaches take on the same invariant, nested geometries that grace nature everywhere.

The aim of this review is to provide an introduction to the ideas and concepts that underpin modern ideas about galaxy formation in a universe in which cosmic structures build up hierarchically through gravitational instability. (3104)

Bennett, Charles. Cosmology from Start to Finish. Nature. 440/1126, 2006. The latest views in a special section on the Early Universe. Aspects in need of work are its instant origin and ultimate fate. But the presence along the way of a personal creative intelligence able to describe such vistas, on the cusp of self-discovery, remains of no account.

With recent precise measurements of the cosmic microwave background radiation, large galaxy redshift surveys, better measurements of the expansion rate of the Universe and a host of other astrophysical observations, there is now a standard, highly constrained cosmological model. Unidentified dark particles dominate the matter content of our Universe, and mysteries surround the processes responsible for the accelerated expansion at its earliest moments and for its recent acceleration.

Biteau, Jonathan. Stellar Mass and Star Formation Rate within a Billion Light Years. arXiv:2105.11345. We cite this entry by a University of Paris-CNRS astrophysicist, which builds upon some 100 references, so to pause and wonder how incredible it is that evanescent beings on a minute bioworld can yet altogether be able to explore, quantify and describe the depth and expanse of a spatial and temporal universe reality from which they arose. What a fantastic scenario becomes apparent. Whomever are we Earthlings, for what purpose may we ask, what great discovery could there be to achieve?

To develop galaxy-targeting approaches, the gravitational-wave community built a catalog of stellar mass in the local universe based on the 2MASS spectroscopic and photometric redshift surveys. By cleaning and supplementing this catalog, the present work aims to establish a near-infrared flux-limited sample to map both stellar mass and star formation rate (SFR) over the full sky. Scaling relations with stellar mass as a function of morphology are used to construct a SFR cosmography in the local universe. The present work provides in particular new bases for modeling the large- and intermediate-scale anisotropies observed at ultra-high energies. (Abstract excerpt)

Bluck,, Asa, et al. What Shapes a Galaxy? Unraveling the Role of Mass, Environment and Star Formation in Forming Galactic Structure. arxiv:1902.01665. A dozen astrophysicists from Canada, the UK, Switzerland, and Australia proceed to test, quantify and find out. But our interest is to record how really fantastic is it that our collaborative human intellects upon a minutest bioworld are yet capable at all of learning any reach of space and time. Who are we suddenly sapient, literate, instrumental beings to do this, what august purpose might be imagined.

We investigate the dependence of galaxy structure on a variety of galactic and environmental parameters for ∼500,000 galaxies at z<0.2, taken from the Sloan Digital Sky Survey data release 7. We rank galaxy and environmental parameters in terms of how predictive they are of galaxy structure, using an artificial neural network approach. We find that distance from the star forming main sequence, followed by stellar mass, are the most closely connected parameters to the bulge to stellar mass ratio. In our simulations, we find a significant lack of bulge-dominated galaxies at a fixed stellar mass, compared to the SDSS. (Abstract excerpt)

Boguna, Marian, et al. Cosmological Networks. New Journal of Physics. 16/093031, 2014. Physicists Marian Boguna, University of Barcelona, Maksim Kitsak, Northeastern University, and Dmitri Krioukov, University of California, San Diego continue their “Network Cosmology” project (search authors). As usual, the first paragraph notes how every other natural and social domain has been found to be distinguished and sustained by nodes and links in dynamic associations, except for the physical universe. By applying condensed matter methods, the same web phenomena can be discerned across celestial reaches from particles to galaxies. And by natural philosophy view, a cosmic Copernican revolution appears in our worldwide midst by way of these universally animate recursive iterations, which come to life and mind in our worldwide midst.

Networks often represent systems that do not have a long history of studies in traditional fields of physics, albeit there are some notable exceptions such as energy landscapes and quantum gravity. Here we consider networks that naturally arise in cosmology. Nodes in these networks are stationary observers uniformly distributed in an expanding open FLRW universe with any scale factor, and two observers are connected if one can causally influence the other. We show that these networks are growing Lorentz-invariant graphs with power-law distributions of node degrees. New links in these networks not only connect new nodes to existing ones, but also appear at a certain rate between existing nodes, as they do in many complex networks. (Abstract)

Network science is intrinsically multidisciplinary because the systems it studies come from different domains of science. Complex networks are everywhere indeed in communication technologies, social and political sciences, biology and medicine, economics, or even linguistics. That is why many fields of science – computer science, social sciences, biology, statistics, mathematics, and certainly physics - have contributed tremendously over the last decade to network research. Surprisingly, even though statistical physics has been applied with great success to understanding complex networks, the systems that these networks represent can rarely display a long history of broad interest and focused research in traditional fields of physics. (1)

Here we add to this relatively short list of complex physical networks, a class of networks that naturally arise in cosmology. Specifically, we consider evolving networks of causal connections among stationary (comoving) observers, homogeneously distributed in any open Friedmann-Lemaitre-Robertson-Walker (FLRW) spacetime. These networks are purely classical. Nodes can represent a dust of classical particles, or galaxies, or indeed imaginary observers, scattered randomly throughout the space. (1)

Brandenburg, Brandenburg, Axel and Evangelia Ntormousi.. Galactic Dynamos. arXiv:2211.03476.. Nordita, KTH Royal Institute of Technology and Scuola Normale Superiore, Pisa, Italy post a 2023 entry for the Annual Review of Astronomy and Astrophysics as a thorough 40 page, 230 reference, survey all about this important magnetic phenomena. By our Planatural PhiloSophia vista, we are moved to wonder how fantastic it is that we infinitesimal curious, collaborative beings can yet proceed to quantify any infinite phase and feature.
