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

Animate Cosmos > cosmos > Quantum Cosmology

Gielen, Steffen and Joao Magueijo. Quantum Resolution of the Cosmological Singularity. arXiv:2204.01771. We cite this posting by University of Sheffield and Imperial College London physicists as one example of frontier Earthuman abilities to plumb and span, so it seems, any depth and breadth of the entire universal expanse, and beyond. Once again it is fantastic to contemplate that such “microcosmic” entities themselves, as they now altogether reside and collaborate within a global cerebral-sphere, can yet accomplish these quantifications across so many orders of magnitude. Might a reason be that planetary peoples are ultimately meant to become ecosmic cocreators?

(2109.02660) and Cosmological Time and the Constants of Nature by JM at (2104.11529). And at the same while that barbaric conflicts, senseless destruction, maybe nuclear war, rages. However can we awake in time to our true winfinity identity.

Animate Cosmos > cosmos > Quantum Cosmology

Kinney, Will. An Infinity of Worlds: Cosmic Inflation and the Beginning of the Universe. Cambridge: MIT Press, 2022. A veteran SUNY Buffalo physicist writes a latest theoretical survey of this apparent instant origin. A novel expansion goes on to consider a multiversal occasion.

In the beginning was the Big Bang: an unimaginably hot fire almost fourteen billion years ago in which the first elements were forged. The physical theory of the nascent universe—the Big Bang—was a most consequential development in twentieth-century science. And yet it leaves many questions unanswered. Kinney argues that cosmic inflation is a transformational idea in cosmology, changing our picture of the basic structure and raising questions about what we mean by a scientific theory. He explains that inflation is a remarkable unification of inner space and outer space, in which the physics of the very large (the cosmos) meets the physics of the very small (particles and fields), closing in a full circle at the first moment of time.

Animate Cosmos > cosmos > exouniverse

Baumgartner, Sandra and Jaiyul Yoo. Living in a Non-Flat Universe. arXiv:2205.12973. We cite this entry by University of Zurich astrophysicists as an example of our latest abilities to advance Earthuman quantifications onto entire cosmoses. In regard, the project involves both queries about physical parameters of our own universe, and beyond to consider multiverse candidates. See Separate Universe Approach to Evaluate Nonlinear Matter Power Spectrum at 2205.10339 for similar work.

Recent analysis of the Planck measurements opened a possibility that we live in a non-flat universe. Given the renewed interest in non-zero spatial curvature, here we re-visit the light propagation in a non-flat universe and provide gauge-invariant expressions for the cosmological probes: the luminosity distance, galaxy clustering, gravitational lensing, and microwave background anisotropies. Our work represents the first comprehensive investigation of the cosmological probes in a non-flat universe. (Abstract)

Animate Cosmos > cosmos > exouniverse

Terasawa, Ryo, et al. Separate universe approach to evaluate nonlinear matter power spectrum for non-flat ΛCDM model. arXiv:2205.10339. We cite this entry by four Japanese cosmologists as an example of how the latest Earthuman science is able to extend its compass to myriad other cosmoses. See also Likelihood Criteria for the Universe by Ezequiel Lopez-Rubio at 2206.0097 for another take.

The spatial curvature of the universe is a fundamental quality that could give a link to its early physics. We develop a method to compute the nonlinear matter power spectrum for "non-flat" ΛCDM models using the separate universe (SU) ansatz whence the curvature of structure formation is equivalent to that of long-wavelength density fluctuation. We find that the emulators, those built for flat cosmologies such as EuclidEmulator, can predict the non-flat P(k) with least degradation. (Excerpt)

In physics and mathematics, an ansatz is an educated guess or an additional assumption made to help solve a problem, and which may later be verified to be part of the solution by its results.

Animate Cosmos > cosmos > exouniverse

Wood, Charlie. Pondering the Bits that Build Space-Time and Brains. Quanta. April 20, 2022. The entry is at once a lifetime profile of the University of Pennsylvania polyphysicst VijaY Balasubramanain, and a wide survey of theoretical frontier imaginations. In addition, he directs a second research group at Penn that studies how the world’s physical features may have sculpted the brain via information and computation as a natural language. For examples of his current, collegial work see Entanglement between Two Gravitating Universes at arXiv:2104.13383 and See Spin Structures and Baby Universes at 2007.04333. Into the 2020s, it seems to be newly accessible to consider, quantify and play with whole cosmoses.

In 1989, the renowned physicist John Wheeler proposed a radical new way to think about the universe. Quantum particles may shape-shift and disappear, but we can always count on information. Wheeler speculated that bits of information could be the fundamental ingredient of reality. Every physical quantity, every it, derives an ultimate significance from bits, binary yes-or-no indications, he wrote in an essay envisioning an “it from bit” cosmos. (quote)

Animate Cosmos > Organic > Chemistry

Cejkova, Jitka and Julyan Cartwright. Chembrionics and Systems Chemistry. ChemSystemsChem. 4/3, 2022. For this new Chemistry Europe journal, University of Chemistry and Technology, Prague, and University of Granada polychemists describe this novel approach which reveals another way that living beingness can be seem to spontaneously arise wherever it can (search JC, Cardoso).

Chemobrionics is a core topic of systems chemistry, as it plays a central role in understanding complex self-assembling systems and is related to work done on the origin of life as well as the design of complex materials. The ChemSystemsChem Special Collection on Chemobrionics showcases some of the most exciting work done in this field today. (Abstract)

Animate Cosmos > Organic > Chemistry

Koksal, Elif, et al. Spontaneous Formation of Prebiotic Compartment Colonies on Hadean Earth and Pre-Noachian Mars. ChemSystemsChem. 4/3, 2022. This new Chemistry Europe publication is dedicated to the Systems Chemistry endeavor, which has not been recently had its own journal. Here a six person team from the University of Oslo, Vienna and Copenhagen because it reports how early planetary crustal environs possess intrinsic conditions which favor the formation of autonomous protocellular aggregates. These bounded capsules can then facilitate non-enymatic DNA reactions. As such studies advance into the 2020s they reveal further evidence of an innate ecosmic fertility.

Animate Cosmos > Thermodynamics

Babajanyan, S., et al. Thermodynamic Selection. arXiv:2203.10308. SB and Eugene Koonin, National Library of Medicine NIH along with A. Allahverdyan, Yerevan Physics Institute, Armenia post a mathematic exercise with 100 references about the latest theoretical intersects between life’s oriented evolution to our Earthuman observance and a a substantial energetic basis which seems deeply conducive for this occasion So once again it seems, even across imperiled lands, that human beings will be inherently moved and capable wherever possible to accomplish such ecosmic self-quantification.

Overall, we found that simple models with no special assumption beyond the laws of thermodynamics can recapitulate certain features of biological evolution. (12)

Animate Cosmos > Thermodynamics > quant therm

Ball, Philip. Physicists Rewrite the Fundamental Law that Leads to Disorder. Quanta. May 26, 2022. In this significant article, the British polyscholar science writer surveys a rush of current advances which altogether well imply an historic revision of 19th century thermodynamic theories By a novel inclusion of quantum information qualities, the entropic demise implied by the second law from Ludwig Boltzmann (1877) can be set aside and moved beyond. This wide=ranging entry builds its case by enjoining the thought and writings of key contributors such as Chiara Marletto and David Deutsch (constructor theory), along with Vlatko Vedral, Gilad Gour, Markus Muller and others.

In addition quantum physicists such as Giulio Chiribella (search), Carlo Scandolo and Nicole Yunger Halpern provide insights based on relational aspects, resource computations, networks and more. Earlier work such as The Resource Theory of Informational Nonequilibrium in Thermodynamics by Gilad Gour, et al (1309.6586) and Quantum Resource Theories by Eric Chitambar and GG in Reviews of Modern Physics (91/025001, 2019) set the scene for Linear Growth of Quantum Circuit Complexity by Jonas Haferkamp, et al in Nature Physics (18/528, 2022), General Quantum Resource Theories by Kohdai Kuroiwa and Hayala Yamasaki (2002.02458), The First Law of General Quantum Resource Theories by Carlo Sparacian in Quantum (4/259, 2020), and Resource Theory of Quantum Uncomplexity by Nicole Yunger Halpern, et al (2110.11371).

The second law of thermodynamics is among the most sacred in all of science, but it has always rested on 19th century arguments about probability. New arguments trace its true source to the flows of quantum information. (Summary)

Yet physicists don’t just want descriptions of what will probably happen. Can the second law be tightened up into more than just a statement of likelihoods? A number of independent groups appear to have done just that. They have woven the second law out of the fundamental principles of quantum mechanics, which may have directionality and irreversibility built into them at the deepest level. According to this view, the second law comes about not because of classical probabilities but because of quantum effects such as entanglement. And it arises from from the most natural basis that we know of — the quantum resource of information. (1)

Crucially, the quantum informational approach suggests a way of getting rid of the statistical picture that bedevils the classical view, where you have to take averages over ensembles of many different microstates. “The true novelty with quantum information came with the understanding that one can replace ensembles with entanglement with the environment,” said Carlo Maria Scandolo of the University of Calgary. (5)

Quantum resource theories allow a kind of zooming in on the fine-grained details of the classical second law. We don’t need to think about huge numbers of particles; we can make statements about what is allowed among just a few of them. When we do this, said Nicole Yunger Halpern, it becomes clear that the classical second law is just a kind of coarse-grained sum of a whole family of inequality relationships. (6)

Wilson, Matt and Giulio, Chilibella. A Mathematical Framework for Transformations of Physical Processes. arXiv:2204.04319. Hong Kong University – Oxford University Joint Laboratory for Quantum Information and Computation scholars (search GC) post a latest survey as this deepest fundament phase continues to be reconceived into the 21st century (see Quantum Organics above). As the quotes allude, an historic reset includes a cross- integration with the macro “classical” phase, whereby quantum phenomena can be found to exhinit the same complex network system qualities as everywhere else. Herein this paper expands upon a shift from a particulate focus to equally important relations in between.

We also cite because Chilibella’s work is noted by Philip Ball (2022) as a vital contribution to 2020s revisions of thermodynamic drives. For more see his The Nonequilibrium Cost of Accurate Information Processing (2203.09369) and Transforming Quantum Operations: Quantum Supermaps in Europhysics Letters (83/3, 2008).

We observe that the existence of sequential and parallel composition supermaps in higher order physics can be formalized using enriched category theory. Encouraged by physically relevant examples such as unitary supermaps, we model higher order physics in analogy with the process theoretic framework and monoidal categories. We then show that higher order physical theories can result from the combined existence of parallel and sequential composition supermaps with an additional feature of "linking". The aim of the proposed definitions is to give a better way to study novel causal structures in quantum theory, and, more broadly, provide a paradigm of physical theory where static and dynamical features are treated in a unified way. (Abstract excerpt)

Traditionally, physical theories have been concerned with the laws governing the evolution of particles or fields. In the ontology of a theory, the physical systems are regarded as objects, while their evolution is a way to predict relations among objects in different regions of space and time. Over the past decade, a series of works in quantum information theory started exploring the idea that processes themselves could be regarded as objects, which can be acted upon by a kind of higher order physical transformations, known as quantum supermaps. Quantum supermaps have found a wide range of applications to quantum information and computation, and to the study of new types of causal structures arising in quantum mechanics. In addition, higher order transformations provide a broad framework for general physical theories with dynamical causal structure. (1)

Animate Cosmos > Thermodynamics > autocat

Kolchinsky, Artemy. A Thermodynamic Threshold for Darwinian Evolution. arXiv:2112.02809. The author has a 2015 doctorate in Informatics of Complex Systems from Indiana University, then some years at SFI, and is now at the Universal Biology Institute of Tokyo University where he studies intersects between information, physics and an animated nature. This entry proceeds with an emphasis on self-making, ecosmo-poiesis features of a genesis universe which seems to involved with its own autocatalytic cocreation.

Understanding the thermodynamics of Darwinian evolution has important implications for biophysics, evolutionary biology, and the origin of life. We show that for autocatalytic replicators in a nonequilibrium steady state, the critical selection coefficient is lower bounded by the Gibbs free energy dissipation. This bound presents a fundamental threshold for Darwinian evolution, which is complementary to other thresholds that may arise from finite population sizes, mutation rates, etc. Our results apply to a large class of molecular replicators, including many autocatalytic sets and multistep mechanisms.

Animate Cosmos > Anthropic

Krizek, Michal and Lawrence Somer. Anthropic Principle and the Hubble-Lemaitre Constant. Galaxies. May, 2022. Czech Academy of Sciences and Catholic University of America theorists provide a latest insight into how finely conceived our natural cosmos appears at its deepest substantial phases. From the 1970s to today there just seems to be such curious affinities that are not yet understood.

According to the weak formulation of the anthropic principle, all fundamental physical constants have just such values which enabled the origin of life. Here we demonstrate that the current value of the Hubble–Lemaître constant was also vital to the presence of humankind. Life on Earth has existed continually for at least 3.5 Gyr, which requires very stable conditions over this long interval. Nevertheless, as the luminosity of the Sun increases, Earth has receded from the Sun by an appropriate speed such that it received an almost constant solar flux during this time. (Abstract)

Animate Cosmos > Astrobiology

Lingham, Manasvi and Abraham Loeb. Life in the Cosmos: From Biosignatures to Technosignatures. Cambridge: Harvard University Press, 2021. Akin to Wade Roush herein, a Florida Institute of Technology astrobiologist and a senior Harvard astronomer provide the latest broad and deep considerations.

“Are we alone in the universe?” Today the search for signatures of extraterrestrial life and intelligence has become an active scientific endeavor. Manasvi Lingam and Avi Loeb tackle three areas of interest in hunting for life “out there”: first, the pathways by which life originates and evolves; second, planetary and stellar factors that affect the habitability of worlds and biomarkers that may reveal microbial life; and finally, the detection of technological signals that could be indicative of intelligence. Drawing on empirical data, as well as the latest theoretical and computational developments, the authors make a compelling scientific case for the search for animate exoworlds.

Animate Cosmos > Astrobiology

Roush, Wade. Extraterrestrials. Cambridge; MIT Press, 2020. A veteran science and technology writer reviews every aspect about whomever, if anyone else at all, might by some neighborly presence in an apparent fertile, prolific cosmos – or is it?

Are we alone in the universe? If not, where is everybody? All we know about how planets form and life arises suggests that our Earth should not be unique.. This paradox first noted by the physicist Enrico Fermi, has fueled much debate, speculation, and now some actual science. Roush reviews the latest thinking among astronomers and astrobiologists, and the Search for Extraterrestrial Intelligence (SETI) as a work in process. Finally, he discusses ways to resolve to the Fermi Paradox.

Animate Cosmos > exoearths

Boyle, Rebecca. Astronomers Reimagine the Making of the Planets. Quanta. June 6, 2022. A science writer continues to survey our worldwise retrospective studies of how this Earth, our solar system, and orbital orrerys tend to array into myriad varieties. Her prior report was As Planet Discoveries Pile Up, a Gap Appears in the Pattern (May 16, 2019) which noted an absence in the galaxy of 1.5 to 2 times Earth size worlds. Three years and 5,000 total findings later, still “none that remotely resemble ours” was found She comments that Alessandro Morbidelli, a leading researcher, finds the situation quite curious. A prime reference is then Planet Formation Theory in the Era of ALMA and Kepler: From Pebbles to Exoplanets by Joanna Drazkowaka and nine coauthors including AM at arXiv:2203.09759 (see herein).
