Book excerpt: Is the universe actually a giant quantum computer? According to Seth Lloyd, the answer is yes. All interactions between particles in the universe, Lloyd explains, convey not only energy but also information–in other words, particles not only collide, they compute. What is the entire universe computing, ultimately? “Its own dynamical evolution,” he says. “As the computation proceeds, reality unfolds.” Programming the Universe, a wonderfully accessible book, presents an original and compelling vision of reality, revealing our world in an entirely new light.

Download or read book Twenty Worlds written by Niall Deacon and published by Reaktion Books. This book was released on 2020-09-17 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thirty years ago, the only planets we knew were the ones orbiting our own sun; we now know of thousands of other worlds orbiting distant stars. In this book, astronomer Niall Deacon journeys to twenty of these globes: from giant, blisteringly hot planets orbiting close to their parent stars to planets that float through the cold wilderness of space alone, and from dead stars shredding asteroids to worlds made of diamond—and even planets that may be similar to the Earth. Deacon also takes in the latest exoplanet discoveries and explains how astronomers have come to learn so much about these strange and distant worlds. Twenty Worlds tells a sweeping story, of real planets around other stars, and it will fascinate a universe of fans of popular science and astronomy.

Download or read book REAL UNREAL COSMOS written by SAURABH GUPTA and published by Saurabh Gupta. This book was released on 2022-05-14 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: REAL UNREAL COSMOS is a non-fiction, physics & cosmology related book in which we talk about the Simulation Hypothesis i.e in simple words, Have you ever wondered, Who & Where is God? our almight creator that we pray and seek. Is everything that happens with us - our victories, losses & luck already preplanned? The universe in which we live, eat, feel, love, lose, achieve overall EXIST itself only doesn't seem to be real or authentic reality. Whatever we feel or see is just the image that our brain manifests for us to see hence the overall universe we call reality is nothing other than a mere simulation or a fake-world to be precise. We as humans have developed so far in technology that we created so much in this world. But......what if we're not creators but CREATIONS? Just like simple another character in a video game. So, Who is the Creator? REAL UNREAL COSMOS doesn't only just places myths behind facts like mere fantasies or probabilities but provides substantial evidence for why our universe, our cosmos, our reality, our existence is not real. Each chapter in the book provides an evidence or a reason to believe that REALITY IS UNREAL and that's what is REAL UNREAL COSMOS for you. ABOUT THE AUTHOR : SAURABH GUPTA is a Mumbai based Indian 21 years old cosmology & physics enthusiast with a Bachelors in Information Technology. He has a love for gaming and it was while a gaming session which brought upon the whole idea of this book. It took almost 3-5 years of research to complete his book. He is also an aspiring application developer. He always had a craving curiosity to learn, understand and manifest the universe since childhood. Due to his everlasting love for space and craving curiosity for the mysteries of the universe, he began researching in cosmology and theoretical physics as early as when he was in 5th grade. He started to study the universe deeply; and when he was in 5th grade, his love and interest in space rose at an exponential extent. What happened was, he usually kept records of the several satellites and spacecraft and kept on tracking them. And on a particular night he witnessed and observed the ISS (International Space Station) revolving around the earth through the sky and that was the moment which gave that chills of his and the existence of the universe around him.

Download or read book The Universe in a Box written by Andrew Pontzen and published by Penguin. This book was released on 2023-06-13 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientists are using simulations to recreate the universe, revealing the hidden nature of reality. Cosmology is a tricky science—no one can make their own stars, planets, or galaxies to test its theories. But over the last few decades a new kind of physics has emerged to fill the gap between theory and experimentation. Harnessing the power of modern supercomputers, cosmologists have built simulations that offer profound insights into the deep history of our universe, allowing centuries-old ideas to be tested for the first time. Today, physicists are translating their ideas and equations into code, finding that there is just as much to be learned from computers as experiments in laboratories. In The Universe in a Box, cosmologist Andrew Pontzen explains how physicists model the universe’s most exotic phenomena, from black holes and colliding galaxies to dark matter and quantum entanglement, enabling them to study the evolution of virtual worlds and to shed new light on our reality. But simulations don’t just allow experimentation with the cosmos; they are also essential to myriad disciplines like weather forecasting, epidemiology, neuroscience, financial planning, airplane design, and special effects for summer blockbusters. Crafting these simulations involves tough compromises and expert knowledge. Simulation is itself a whole new branch of science, one that we are only just beginning to appreciate and understand. The story of simulations is the thrilling history of how we arrived at our current knowledge of the world around us, and it provides a sneak peek at what we may discover next.

Book excerpt: In this thesis, we harness the power of modern scientific computing to explore the formation and evolution of cosmological structure in a wide variety of astrophysical scenarios. We explore the nonlinear dynamics associated with the interplay between cold dark matter (CDM), baryons, ionizing radiation, and cosmic neutrinos, within regimes where analytic calculations necessarily fail. We begin by providing an overview of structure formation and its connections to the fields of study considered here: the epoch of reionization, galactic substructure evolution, and cosmic neutrinos. We then present a rigorous numerical convergence study of cosmological hydrodynamics simulations post-possessed with radiative transfer to study the impact of small-scale absorption systems within the intergalactic medium (IGM) during the onset of reionization. We present converged statistics of the IGM on smaller scales and earlier times than previously considered. Moreover, we provide strict resolution limits for hydrodynamic simulations to properly resolve the unheated IGM. Next we study the infall and dynamical evolution of CDM halos in a galactic host. We find the behaviour of low-mass subhalos is qualitatively different than previously described for high-mass subhalos. In particular, the evolution of low-mass subhalos, with masses less than 0.1 per cent that of the host, is mainly driven by their concentration. This presents an opportunity to use concentration as a predictive indicator of substructure evolution. We finish this thesis with an investigation of a recently proposed method for constraining individual neutrino mass from cosmological observations. Such a detection depends on the ability to reconstruct the CDM-neutrino relative velocity, which we show can be accomplished using linear transformations of an observed galaxy field. Based on this, we perform the world's largest cosmological N-body simulation and present preliminary results for the observational prospects of cosmic neutrinos.

Download or read book The Routledge Handbook of Panpsychism written by William Seager and published by Routledge. This book was released on 2019-12-10 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: Panpsychism is the view that consciousness – the most puzzling and strangest phenomenon in the entire universe – is a fundamental and ubiquitous feature of the world, though in a form very remote from human consciousness. At a very basic level, the world is awake. Panpsychism seems implausible to most, and yet it has experienced a remarkable renaissance of interest over the last quarter century. The reason is the stubbornly intractable problem of consciousness. Despite immense progress in understanding the brain and its relation to states of consciousness, we still really have no idea how consciousness emerges from physical processes which are presumed to be entirely non-conscious. The Routledge Handbook of Panpsychism provides a high-level comprehensive examination and assessment of the subject – its history and contemporary development. It offers 28 chapters, appearing in print here for the first time, from the world’s leading researchers on panpsychism. The chapters are divided into four sections that integrate panpsychism’s relevance with important issues in philosophy of mind, philosophy of science, metaphysics, and even ethics: Historical Reflections Forms of Panpsychism Comparative Alternatives How Does Panpsychism Work? The volume will be useful to students and scholars as both an introduction and as cutting-edge philosophical engagement with the subject. For anyone interested in a philosophical approach to panpsychism, the Handbook will supply fascinating and enlightening reading. The topics covered are highly diverse, representing a spectrum of views on the nature of mind and world from various standpoints which take panpsychism seriously.
Download or read book Dynamic Structures in an Open Cosmos written by Mathias Hüfner and published by BoD – Books on Demand. This book was released on 2021-12-01 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: The restoration of the Pontifical Academy of Sciences served to reconcile science with faith. In other words, physics should be made subservient to faith. The spiritual shepherd nourishes his sheep using paradoxes. For example, the immaculate conception served for centuries. But this belief isn't time relevant anymore. Better is a beliefe based on mathematics. Modern physics is characterized by a number of paradoxes that can be traced back to the incorrect use of mathematical means of expression in a closed system. Now, out of concern for the common house, Pope Francis has released the connection to a closed theory with the groundbreaking sentence: "In this universe made up of open systems that communicate with one another, we can discover innumerable forms of relationship and participation." Now we are any more looking relativistically at the cosmos as a symmetric blown up ball. We are going back to a real view of an energy dissipative world. Read how we build on the successes of physics in the 19th century and apply the ideas of Iljy Prigogine on the thermodynamics of open systems to dynamic vortex structures in an open cosmos. Mechanics, thermodynamics and electrodynamics merge with Maxwell's and Stokes' equations to form a unit and the paradoxes disappear wonderfully and we now recognize that a projection of a real vortex filament into a plane gave rise to the idea of an abstract quantum mechanical wave function. This gives us simple physics from the macrocosm to the microcosm, free of contradictions, and we learn how nuclear fusion really works. This opens up a clean, CO2-free, effective energy source for us in the future. The book assumes a basic mathematical and scientific understanding, as it should be conveyed in high schools, but complicated mathematical derivations are largely dispensed with. After "Modern Astrophysics meets Engineering", it is the author's second book.
