How Einstein’s relativity unlocks the past, present and future of the cosmos
Author: New Scientist
Publisher: Hachette UK
How did it all begin? Where is it all going? A little over a century ago, a young Albert Einstein presented his general theory of relativity to the world and utterly transformed our understanding of the universe. His theory changed the way we think about space and time, revealed how our universe has been expanding from a hot dense state called the big bang and predicted black holes. WHERE THE UNIVERSE CAME FROM is a 13.8-billiion-year journey through the cosmos. Discover how Einstein's work explains why the cosmos is the way it is, why 95% of the universe is missing, how physicists go to extraordinary lengths to unlock gravity's secrets and how black holes could hold the key to a theory of everything. ABOUT THE SERIES New Scientist Instant Expert books are definitive and accessible entry points to the most important subjects in science; subjects that challenge, attract debate, invite controversy and engage the most enquiring minds. Designed for curious readers who want to know how things work and why, the Instant Expert series explores the topics that really matter and their impact on individuals, society, and the planet, translating the scientific complexities around us into language that's open to everyone, and putting new ideas and discoveries into perspective and context.
Consequences of quantum gravity on grander scales are expected to be enormous: only such a theory can show how black holes really behave and where our universe came from. Applications of loop quantum gravity to cosmology have especially by now shed much light on cosmic evolution of a universe in a fundamental, microscopic description. Modern techniques are explained in this book which demonstrate how the universe could have come from a non-singular phase before the big bang, how equations for the evolution of structure can be derived, but also what fundamental limitations remain to our knowledge of the universe before the big bang. The following topics will be covered in this book: Hamiltonian cosmology: a general basic treatment of isotropy, perturbations and their role for observations; useful in general cosmology. Effective equations: an efficient way to evaluate equations of quantum gravity, which is also useful in other areas of physics where quantum theory is involved. Loop quantization: a new formalism for the atomic picture of space-time; usually presented at a sophisticated mathematical level, but evaluated here from an intuitive physical side. The book will start with physical motivations, rather than mathematical developments which is more common in other expositions of this field. All the required mathematical methods will be presented, but will not distract the reader from seeing the underlying physics. Simple but representative models will be presented first to show the basic features, which are then used to work upwards to a general description of quantum gravity and its applications in cosmology. This will make the book accessible to a more general physics readership.
A new window opens onto the cosmos... Almost every day we are challenged by new information from the outermost reaches of space. Using straightforward language, One Universe explores the physical principles that govern the workings of our own world so that we can appreciate how they operate in the cosmos around us. Bands of color in a sunlit crystal and the spectrum of starlight in giant telescopes, the arc of a hard-hit baseball and the orbit of the moon, traffic patterns on a freeway and the spiral arms in a galaxy full of stars--they're all tied together in grand and simple ways. We can understand the vast cosmos in which we live by exploring three basic concepts: motion, matter, and energy. With these as a starting point, One Universe shows how the physical principles that operate in our kitchens and backyards are actually down-to-Earth versions of cosmic processes. The book then takes us to the limits of our knowledge, asking the ultimate questions about the origins and existence of life as we know it and where the universe came from--and where it is going. Glorious photographs--many seen for the first time in these pages--and original illustrations expand and enrich our understanding. Evocative and clearly written, One Universe explains complex ideas in ways that every reader can grasp and enjoy. This book captures the grandeur of the heavens while making us feel at home in the cosmos. Above all, it helps us realize that galaxies, stars, planets, and we ourselves all belong to One Universe.
The MTV Generation (Generation X's protege) is stereotyped as apathetic, ineffectual, entitled and lazy. David Schuster is here to show you that things are not always what they seem. In a world dominated by the opinions of Baby Boomer pundits, Schuster adds a youthful voice to the cacophony. Politically incorrect, incisive and funny, Schuster waxes philosophical on the most important sociological quandaries of the Western world. He tackles everything from sex to metaphysics with optimism and authenticity uncharacteristic of his generation. Always careful not to take himself too seriously, he offers a refreshing viewpoint badly needed in a cynical world constantly bombarded by doomsday warnings. Philosophy Junk Food is an entertaining peek into what the younger crowd has been up to while you weren't looking, with just enough profound messages to change the way you look at the world.
Christian parenting is hard work--and it's getting harder. Parents have a deep desire to pass on their faith, but fear that today's increasingly skeptical and hostile world will eventually lead their kids to reject the truth of Christianity. That leaves many parents feeling overwhelmed--uncertain of what they can do to help their children, given the difficulty and extent of the faith challenges they will face. This practical and timely resource gives parents the confidence of knowing what to discuss with their children and how to discuss it in order to facilitate impactful conversations that will form the basis of a lifelong faith. In a friendly, parent-to-parent voice, Natasha Crain identifies 30 specific conversations about God that parents must have with their children, organizing them under the categories of - the existence of God - science and God - the nature of God - believing in God - the difference God makes Chapters are sequenced in a curriculum-oriented way to provide a cumulative learning experience, making this book a flexible resource for use in multiple settings: homes, church classes, youth groups, small groups, private Christian schools, and homeschools. Every chapter has a step-by-step conversation guide with discussion questions and tips, and content is readily adaptable for use with kids of any age (elementary through high school). Endorsements: "My prayer is that God will use this book to both motivate and equip you to help your kids develop convictions about their faith."--From the foreword by Sean McDowell, PhD, Biola University professor, speaker, and author of more than eighteen books, including A New Kind of Apologist "I can't think of a more relevant or more needed book for parents raising kids in today's culture. This book on apologetics will lead parents in critical conversations that will help grow and guide kids to be lifelong followers of Christ."--Kristen Welch, author of Raising Grateful Kids in an Entitled World "Hey parents: Do you want to reduce the chances that your child will follow the crowd to the point of rejecting Christ and the values and truths you hold so dearly? Then you need to have the conversations that Natasha Crain so brilliantly describes in this book. Prevent heartbreak later by reading and heeding this book now!"--Frank Turek, PhD, president of CrossExamined Ministries and author of I Don't Have Enough Faith to Be an Atheist and Stealing from God "May this book lead to thousands more Moms and Dads engaging with their kids through an intelligent faith. And may there be tens of thousands more kids who feel loved because the adults in their lives take their questions seriously."--Jeff Myers, PhD, president, Summit Ministries
"The Big Bang is a clear, simple and entertaining introduction to the greatest discovery in the history of science - the birth of the universe.Written by award-winning broadcaster and cosmologist Marcus Chown, The Big Bang details how 13.82 billion years ago all matter, energy, space - and even time - erupted into being in a titanic fireball. Inside you'll learn how scientists have approached the questions: What was the big bang? What drove the big bang? And what happened before the big bang? The evidence it turns out, is all around us..." --Publisher description.
This book takes the reader through ten areas where Christians misunderstand highly motivating Christian truths. Many Christians have doubts about the reality of God. Attacks, especially in the realm of science, have many questioning whether the God of the Bible is real. Without getting bogged down in the science, Mr. Webster provides assurance that the God of Christianity is the only God.But the God of Christianity has gained a terrible reputation, and Mr. Webster addresses how understanding the biblical message from God's perspective reveals a God who really is good and wonderful and even exciting. Mr. Webster addresses misunderstandings about Christian love and the nature of sin, saving faith, Christian hope (heaven), God's plan, the role of suffering, the role of prayer, the role of Christian forgiveness, and the role of the church, taking the reader back to the Bible over and over to show that Christianity was always meant to be exciting and good.If you grasp the truths in this book, they can change your life in wonderful ways. These truths can truly revitalize your Christianity. These truths can set Christians on fire for their Lord!
In an age of Pharaohs and pyramids, Gods and Oracles, two men fight beliefs that could tear their world apart. Accused of angering the tribe's spirits, and blamed for the raid and kidnapping of two children, Tor and Kel are banished for their closeness. Forced from home and apart from Kel, Tor must follow signs left by the raiders, Kel, and the two childrenSeeking proof about the raid and healing for his doubts about himself, Tor visits the sleep temples of ancient Egypt (Kemet). But Tor's dreams and visions are shared by others also threatened by the growing movement of the raiders: the Pharoah, two of his priests, and a woman claiming to be the Oracle of the Earth.To protect Kemet, the Pharoah sends them to Gebal and Cirali, both vital trading ports under potential threat, to find the truth about their disturbing shared visions and the raiders.The destiny of Tor, Kel, the children, the Oracle, Kemet and Phoenicia will all meet at the Fires of Yanartas, Tor "s writings and stories tell the value of finding yourself, celebrating differences, and the need to stand against hatred and division, and is ultimately a tale of joy and redemption.
