A behind-the-scenes look at the latest tool in astrophysics: computer simulations of the cosmos. Simulating the Cosmos is a behind-the-scenes look at one of the hottest and fastest-moving areas of astrophysics today: simulations of cosmology and galaxy formation. Leading cosmologist Romeel Davé guides you through the trials and tribulations of what it takes to teach computers how galaxies form, the amazing insights revealed by cosmological simulations, and the many mysteries yet to be solved. This rollicking journey is a rare glimpse into science in action, showing how cosmologists are using supercomputers to uncover the secrets of how the universe came to be.

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.
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.
"Simulating Large Scale Structure for Models of Cosmic Acceleration explores alternative cosmological models and how we can learn from these as well as differentiate them from the standard cosmic model. The book also looks at the ways in which techniques can be used to accurately develop and test the model to produce new observations. This self-contained book provides a fundamental guide to researchers looking to enter the field of cosmological simulations. Postgraduate students will also find it of use as the need for numerical simulations and astronomical surveys increases. The book contains a significant amount of Professor Li's own research as well as assistance from other experts and collaborators in the field and will certainly encourage others to explore the ever-expanding world of cosmic acceleration."--Source : résumé de l'éditeur.
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.
The reality behind the reality. Modern quantum theory leaves no doubt: We are living in a simulation that only takes place in our brain. Nothing is real except our conciousness! But where does this simulated "matrix" came from? How can we recognize it? And more important: how can we alter it!? WARNING: Consuming this book can drastically change your life and the way you view it. If you love your life as it is and the world you live in, please DO NOT read this book!
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.
