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.

In this paper, we import techniques from quantum information theory to reveal undiscovered predictions for inflation which, in turn, signals how quantum entanglement across cosmological scales can affect large structural formations. Our key insight is that observable longwavelengths must be part of an open quantum system, so that the quantum fluctuations can decohere in the presence of an environment of shortwavelengs.

I comment at length because this news article aptly suggests how physics, cosmology, and also philosophy have, mostly unbeknownst, taken leave of reality. Physical science, an almost totally male pursuit, after a century of plumbing the depths of space, time and matter, seems now stuck there. For this is where causal answers lie, its paradigm avers, since they will legislate any extant cosmos. But the implied result becomes an alien, pitiless, computing machine, with no place of human observers. Strings are out, it is said, only to be replaced by “tangles.” In Markopoulou and Krib’s version of loop quantum gravity the universe as a giant quantum computer, where each quantum of space is replaced by a bit of quantum information. (31) By replacing loop quantum gravity’s chunks of space with qubits, what used to be a frame of reference – space itself – becomes just a web of information. (31) If the new loop quantum gravity does go the distance, though, it could give us a new sense of our place in the universe. If electrons and quarks – and thus atoms and people – are a consequence of the way spacetime tangles up on itself, we could be nothing more than a bundle of stubborn dreadlocks in space. (31) Castelvecchi, David. Shadow World. Science News. November 17, 2007. A report on the wellreceived ‘conjecture’ of Institute of Advanced Study physicist Juan Maldacena, that also offers a good review of quantum theory frontiers. Another entry is the article by Michael Dine on String Theory and the LHCollider in the December 2007 Physics Today. But are such gyrations akin to Ptolemaic epicycles which tried to prop up a fundamentally erroneous model? In his (Maldecena) vision, the mathematical machinery of strings completely translates into a more ordinary quantum theory of particles, but one whose would live in a universe without gravity. Gravity would be replaced by forces similar to the nuclear forces that prevailed in the universe’s first instants. And this would be a universe with fewer dimensions that the realm inhabited by strings. (315) Just as a hologram creates the illusion of the third dimension by scattering light off a 2D surface, gravity and the however many dimensions of space could be a higherdimensional projection of a drama playing out in a flatter world.

An introduction for a special issue on the frontiers of cosmological science with articles on string theory by Leonard Susskind, loop quantum gravity by Carlo Rovelli and on quantum gravity phenomenology by Giovanni AmelinoCamelia. In the same issue is a note on the work of Nobel laurate Geradus ‘t Hooft on a deterministic quantum physics. Chamcham, Khalil, et al, eds. The Philosophy of Cosmology. Cambridge: Cambridge University Press, 2017. With coeditors Joseph Silk, John Barrow, and Simon Saunders, the proceedings of a Templeton funded September 2014 conference organized by a group with this name (Google) based in New York City, Oxford, and Cambridge. At the outset, while a stellar array such as George Ellis, Bernard Carr, Joel Primack, James Hartle, Sean Carroll, Carlo Rovelli, and David Albert presented, the speakers were 30 men sans any women. Some chapters are The Domains of Cosmology by G. Ellis, Black Holes, Cosmology and the Passage of Time by B. Carr, and The Observer Strikes Back by J. Hartle and Thomas Hertog. While notice of the anthropic principle, and J. A. Wheeler’s “it from bit” circuit popped up, the collection remains fixated within an abstract cosmos devoid of a vivifying source, personal destiny or phenomenal essence of its own. Childs, Andrew, et al. Universal Computation by MultiParticle Quantum Walk. Science. 339/791, 2013. We cite this work by University of Waterloo, Canada, scientists from Combinatorics & Optimization, Quantum Computing, and Physics & Astronomy departments as a good instance of this total rethinking and appropriation of nature’s essence as a communicative complex system, similar to every other strata from universe to us. A quantum walk is a timehomogeneous quantummechanical process on a graph defined by analogy to classical random walk. The quantum walker is a particle that moves from a given vertex to adjacent vertices in quantum superposition. Here we consider a generalization of quantum walk to systems with more than one walker. A continuoustime multiparticle quantum walk is generated by a timeindependent Hamiltonian with a term corresponding to a singleparticle quantum walk for each particle, along with an interaction term. Multiparticle quantum walk includes a broad class of interacting manybody systems such as the BoseHubbard model and systems of fermions or distinguishable particles with nearestneighbor interactions. We show that multiparticle quantum walk is capable of universal quantum computation. Since it is also possible to efficiently simulate a multiparticle quantum walk of the type we consider using a universal quantum computer, this model exactly captures the power of quantum computation. (Abstract) Coley, Alan and George Ellis. Theoretical Cosmology. Classial and Quantum Gravity. 37/1, 2020. Dalhousie University and University of Cape Town physicists inaugurate the 2020s decade with a 50 page survey the past, present and future of salient mathematical, computational, spatial form, temporal course, philosophical aspects. Staying within our own universe, black holes, gravitational waves, singularities, dark energy, nonlinearities, string inflation and more are considered. But again it would seem that there must be some innate, eternal cosmic purpose for valiant participatory human beings whom altogether are capable of observing, quantifying, recording such depths and reaches.
