III. Ecosmos: A Revolutionary Organic Habitable UniVerseA. Quantum Cosmology Unity
When quantum mechanics was developed in the 1920s another revolution in physics was just starting. It began with the discovery that the universe is expanding. For a long time quantum mechanics and cosmology developed independently of one another. Yet the very discovery of the expansion would eventually draw the two subjects together because it implied the big bang where quantum mechanics was important for cosmology and for understanding and predicting our observations of the universe today. (James Hartle, arXiv:1901.03933) Ambjorn, J., et al. The Universe from Scratch. Contemporary Physics. 47/2, 2006. By way of a method to observe and quantify a fluctuating quantum geometry at Planck scales (1033 centimeters) called Causal Dynamical Triangulations. The paradigm of spacetime beginning to emerge from CDT is that of a scaleinvariant, fractal and effectively lowerdimensional structure at the Planck scale, which only at a larger scale requires wellknown features of geometry which accord with our classical intuition. (115) Ananthaswamy, Anil. Cosmic Countdown. New Scientist. July 20, 2019. A science writer (search) gathers and reports on a florescence of physical theories in the literature that appear to presage revolutionary cosmologies. A working image of a Swampland (search arXiv), coined by Harvard physicist Cumrun Vafa, contains mix or miasma of string theories, quantum gravity, relativity, de Sitter vacuum, covariant entropy, black holes, and more conjectures. The article is based on interviews with Vafa, Andrei Linde, Eran Palti, Catherine Heymans, and others, along with Anil’s familiar experience (search). Something deeply vital seems to be brewing, which may lead to novel understandings, or wind up at a new square one. See, for example, The Swampland: Introduction and Review by Palti at arXiv:1903.06239, and Towards a Unified View of Swampland Conjectures by Cesar Gomez (1907.13386). Anders, Janet and Karoline Wiesner. Increasing Complexity with Quantum Physics. Chaos. 21/037102, 2011. University College London and University of Bristol physicists continue the realization that their fields of study have much akin with the subject and theory of nonlinear systems. Statistical mechanics joined forces circe 2007, here it is extended within a seamless nature as it must into quantum phenomena. The Article Outline introduces, enters “laws of quantum physics,” then “quantum complexity” with an emphasis on computational correlations, phase transitions, and effects in biology and thermodynamics. We argue that complex systems science and the rules of quantum physics are intricately related. We discuss a range of quantum phenomena, such as cryptography, computation and quantum phases, and the rules responsible for their complexity. We identify correlations as a central concept connecting quantum information and complex systems science. We present two examples for the power of correlations: using quantum resources to simulate the correlations of a stochastic process and to implement a classically impossible computational task. (037102) Ashtekar, Abhay, et al. Quantum Nature of the Big Bang. Physics Review Letters. 96/141301, 2006. The cosmic singularity can be made more predictable by way of the theories of loop quantum gravity. A quantum bridge is then proposed to link two classical universes, one contracting, the other expanding. Bachlechner, Thomas, et al. Axion Landscape Cosmology. arXiv:1810.02822. We cite this entry by physicists TB, UC San Diego, Kate Eckerle and Oliver Janssen, University of Milan, and Matthew Kleban, NYU as their latest paper which by mathematical finesses that seem to allude to sentient beings able to learn this. I heard Kleban speak on The Axidental Universe at UM Amherst on November 9, second abstract below, and see also by this team MultipleAxion Framework in Physical Review D (98/061301, 2018). We study the cosmology of complex multiaxion theories. With O(100) fields and GUT scale energies these theories contain a vast number of vacua, inflationary trajectories and a natural dark matter candidate. We demonstrate that the vacua are stable on cosmological timescales. In a single theory, both large and smallfield inflation are possible and yield a broad range of cosmological observables, and vacuum decay can be followed by a relatively large number (> 60) of efolds of inflation. Light axions stabilized by gravitational instantons may constitute a natural dark matter candidate that does not spoil an axion solution to the strong CP problem. (Abstract) Bartelmann, Matthias, et al. Cosmic Structure Formation with Kinetic Field Theory. Annalen der Physik. 531/11, 2019. A ten person team from the University of Heildeberg and ETH Zurich offer further ways that this KFT mathematical conception, initiated by the lead author and colleagues in the earlier 2010s, can be seen well reflect and explain the variegated shape and course of celestial topologies. Search the arXiv eprint site by Bartelmann and the KFT term for much more. Kinetic field theory (KFT) is a statistical theory for an ensemble of classical point particles in or out of equilibrium. We here review its application to cosmological structure formation by adapting it to an expanding spatial background and the homogeneous and isotropic, correlated initial conditions for nonlinear cosmic formations. Three approaches are developed which rest either on expanding an interaction operator, averaging the interaction term, or resumming perturbation terms. (Abstract excerpt) Bohm, David. Wholeness and the Implicate Order. London: Routledge & Kegan Paul, 1980. The philosophical physicist draws upon unique insights into quantum theory to describe how an “explicate,” overt universe, its life forms and human dialogic consciousness, emanates from and reflects an “implicate,” unmanifest order. Bojowald, Martin. Foundations of Quantum Cosmology. Online: IOP Publishing, 2020. This latest volume by Penn State University theoretical physicist offers a wideranging survey along with indepth mathematical aspects. Its chapters are Universe on Large and Small Scales, Covariance, Quantum Corrections, Minispace Models, Quantum Gravity, and Inhomogeneous Spacetimes. Bojowald, Martin. Quantum Cosmology: A Review. Reports on Progress in Physics. 78/023901, 2015. The Penn State physicist posts an extensive technical update on the two decade project to coherently join these disparate spatial and temporal domains. Bojowald, Martin. The Universe: A View from Classical and Quantum Gravity. Weinheim: WileyVCH, 2013. The Penn State physicist provides to date an expansive, topical survey from quantum cosmology, black holes, atomic particles, to relativity, waves, states, measurement, and stellar reaches from the big bang to unifications. In regard, a number of cosmic “singularities” are recognized. Now could these novel human abilities to achieve such descriptions, as the apparent way a genesis universe tries to quantify and perceive itself, be realized as a further “singularity” of spectacular import and promise? Bousso, Raphael. The Holographic Principle. Reviews of Modern Physics. 74/825, 2002. A technical paper on a discrete, information rich universe akin to a hologram wherein the information content or measure of a three dimensional volume of space is proportional to the area of its two dimensional outer surface. One popular writeup of this approach is Hogan, Craig. “First Light.” New Scientist. January 11, 2003. A New Scientist update of Bousso's thinking is Touching the Multiverse by Amanda Gefter in the March 6, 2010 issue. Brumfield, Geoff. Cosmology Gets Real. Nature. 422/108, 2003. A news report on the growing affirmation by the worldwide astronomical community of the big bang evolutionary model of the universe. By clarifying the age and makeup of the Universe, researchers have ushered in an era of precision cosmology. (108)
