Astronomer Royal Martin Rees shows how the behaviour and origins of the universe can be explained by just six numbers. How did a single genesis event create billions of galaxies, black holes, stars and planets? How did atoms assemble - here on Earth, and perhaps on other worlds - into living beings intricate enough to ponder their origins? This book describes the recent avalanche of discoveries about the universe's fundamental laws, and the deep connections that exist between stars and atoms - the cosmos and the microscopic world. Just six numbers, imprinted in the big bang, determine the essence of our world, and this book devotes one chapter to explaining each.
A History Today Book of the Year A world-renowned astronomer and an esteemed science writer make the provocative argument for space exploration without astronauts. Human journeys into space fill us with wonder. But the thrill of space travel for astronauts comes at enormous expense and is fraught with peril. As our robot explorers grow more competent, governments and corporations must ask, does our desire to send astronauts to the Moon and Mars justify the cost and danger? Donald Goldsmith and Martin Rees believe that beyond low-Earth orbit, space exploration should proceed without humans. In The End of Astronauts, Goldsmith and Rees weigh the benefits and risks of human exploration across the solar system. In space humans require air, food, and water, along with protection from potentially deadly radiation and high-energy particles, at a cost of more than ten times that of robotic exploration. Meanwhile, automated explorers have demonstrated the ability to investigate planetary surfaces efficiently and effectively, operating autonomously or under direction from Earth. Although Goldsmith and Rees are alert to the limits of artificial intelligence, they know that our robots steadily improve, while our bodies do not. Today a robot cannot equal a geologist's expertise, but by the time we land a geologist on Mars, this advantage will diminish significantly. Decades of research and experience, together with interviews with scientific authorities and former astronauts, offer convincing arguments that robots represent the future of space exploration. The End of Astronauts also examines how spacefaring AI might be regulated as corporations race to privatize the stars. We may eventually decide that humans belong in space despite the dangers and expense, but their paths will follow routes set by robots.
A provocative and inspiring look at the future of humanity and science from world-renowned scientist and bestselling author Martin Rees Humanity has reached a critical moment. Our world is unsettled and rapidly changing, and we face existential risks over the next century. Various outcomes-good and bad-are possible. Yet our approach to the future is characterized by short-term thinking, polarizing debates, alarmist rhetoric, and pessimism. In this short, exhilarating book, renowned scientist and bestselling author Martin Rees argues that humanity's prospects depend on our taking a very different approach to planning for tomorrow. The future of humanity is bound to the future of science and hinges on how successfully we harness technological advances to address our challenges. If we are to use science to solve our problems while avoiding its dystopian risks, we must think rationally, globally, collectively, and optimistically about the long term. Advances in biotechnology, cybertechnology, robotics, and artificial intelligence-if pursued and applied wisely-could empower us to boost the developing and developed world and overcome the threats humanity faces on Earth, from climate change to nuclear war. At the same time, further advances in space science will allow humans to explore the solar system and beyond with robots and AI. But there is no "Plan B" for Earth-no viable alternative within reach if we do not care for our home planet. Rich with fascinating insights into cutting-edge science and technology, this accessible book will captivate anyone who wants to understand the critical issues that will define the future of humanity on Earth and beyond.
A beautiful showcase of Johann Doppelmayr's magnificent Atlas Coelestis that deconstructs its intricately drawn plates and explores its influential ideas. Showcasing Johann Doppelmayr's magnificent 1742 map of the cosmos, Atlas Coelestis, this spectacular guide to the heavens is also a superb introduction to the fundamentals and history of astronomy. Charting constellations, planets, comets and moons, Doppelmayr's Atlas presents the ideas and discoveries of many famous and influential astronomers, including Copernicus, Riccioli, Kepler, Newton and Halley, in intricate colour plates that interweave annotated diagrams and tables with figurative drawings and ornamental features. Here, you can appreciate the beauty of those exquisite astronomical and cosmographical plates and comprehend the details, which are also presented in step-by-step deconstructed form. Astronomer Giles Sparrow elucidates the scientific ideas inherent in each plate, expertly decoding and analysing the complex information contained in them and placing Doppelmayr's sumptuous Atlas in the context of the ground-breaking discoveries made during the Renaissance and Enlightenment periods. A spectacular, revelatory celestial compendium to the cosmos, Phaenomena expands on and explains Doppelmayr's original, awe-inspiring Atlas and reflects upon its influence on the development of the science of astronomy to the present day.
It has already been called the scientific breakthrough of the century: the detection of gravitational waves. Einstein predicted these tiny ripples in the fabric of spacetime nearly a hundred years ago, but they were never perceived directly until now. Decades in the making, this momentous discovery has given scientists a new understanding of the cataclysmic events that shape the universe and a new confirmation of Einstein's theory of general relativity. Ripples in Spacetime is an engaging account of the international effort to complete Einstein's project, capture his elusive ripples, and launch an era of gravitational-wave astronomy that promises to explain, more vividly than ever before, our universe's structure and origin. The quest for gravitational waves involved years of risky research and many personal and professional struggles that threatened to derail one of the world's largest scientific endeavors. Govert Schilling takes readers to sites where these stories unfolded-including Japan's KAGRA detector, Chile's Atacama Cosmology Telescope, the South Pole's BICEP detectors, and the United States' LIGO labs. He explains the seeming impossibility of developing technologies sensitive enough to detect waves from two colliding black holes in the very distant universe, and describes the astounding precision of the LIGO detectors. Along the way Schilling clarifies concepts such as general relativity, neutron stars, and the big bang using language that readers with little scientific background can grasp. Ripples in Spacetime provides a window into the next frontiers of astronomy, weaving far-reaching predictions and discoveries into a gripping story of human ambition and perseverance.
Our universe seems strangely "biophilic," or hospitable to life. Is this happenstance, providence, or coincidence? According to cosmologist Martin Rees, the answer depends on the answer to another question, the one posed by Einstein's famous remark: "What interests me most is whether God could have made the world differently." This highly engaging book explores the fascinating consequences of the answer being "yes." Rees explores the notion that our universe is just a part of a vast "multiverse," or ensemble of universes, in which most of the other universes are lifeless. What we call the laws of nature would then be no more than local bylaws, imposed in the aftermath of our own Big Bang. In this scenario, our cosmic habitat would be a special, possibly unique universe where the prevailing laws of physics allowed life to emerge. Rees begins by exploring the nature of our solar system and examining a range of related issues such as whether our universe is or isn't infinite. He asks, for example: How likely is life? How credible is the Big Bang theory? Rees then peers into the long-range cosmic future before tracing the causal chain backward to the beginning. He concludes by trying to untangle the paradoxical notion that our entire universe, stretching 10 billion light-years in all directions, emerged from an infinitesimal speck. As Rees argues, we may already have intimations of other universes. But the fate of the multiverse concept depends on the still-unknown bedrock nature of space and time on scales a trillion trillion times smaller than atoms, in the realm governed by the quantum physics of gravity. Expanding our comprehension of the cosmos, Our Cosmic Habitat will be read and enjoyed by all those--scientists and nonscientists alike--who are as fascinated by the universe we inhabit as is the author himself.
Richly illustrated with the images from observatories on the ground and in space, and computer simulations, this book shows how black holes were discovered, and discusses what we've learned about their nature and their role in cosmic evolution. This thoroughly updated third edition covers new discoveries made in the past decade, including the discovery of gravitational waves from merging black holes and neutron stars, the first close-up images of the region near a black hole event horizon, and observations of debris from stars torn apart when they ventured too close to a supermassive black hole. Avoiding mathematics, the authors blend theoretical arguments with observational results to demonstrate how both have contributed to the subject. Clear, explanatory illustrations and photographs reveal the strange and amazing workings of our universe. The engaging style makes this book suitable for introductory undergraduate courses, amateur astronomers, and all readers interested in astronomy and physics.
Sir Arthur Stanley Eddington (1882 1944) was a key figure in the development of modern astrophysics, who also made important contributions to the philosophy of science and popular science writing. The Arthur Eddington Memorial Trust was set up after his death in order to hold annual lectures on the relationship between scientific thought and aspects of philosophy, religion or ethics. This 2012 collection gathers together six of these lectures, including contributions by Sir Edmund Whittaker, Herbert Dingle, Richard B. Braithwaite, John C. Eccles, Dame Kathleen Lonsdale, and Baroness Mary Warnock, together with Eddington's 1929 Swarthmore Lecture on Science and the Unseen World. A preface written by the Astronomer Royal, Baron Rees of Ludlow, is also included. This is a fascinating book that will be of value to anyone with an interest in the philosophy of science and Eddington's legacy.

Marvel at the wonders of the Universe, from stars and planets to black holes and nebulae, in this exploration of our Solar System and beyond. Universe opens with a look at astronomy and the history of the Universe, using 3D artworks to provide a comprehensive grounding in the fundamental concepts of astronomy, including the basic techniques of practical astronomy. The core of the book is a tour of the cosmos covering the Solar System, the Milky Way, and galaxies beyond our own. Explanatory pages introduce different celestial phenomena, such as galaxies, and are followed by catalogues that profile the most interesting and important examples. A comprehensive star atlas completes the picture, with entries on each of the 88 constellations and a monthly sky guide showing the night sky as it appears throughout the year as viewed from both the northern and southern hemispheres.
This volume presents an unique and accessible synthesis of modern cosmology. In recent years, observational cosmology has made remarkable advances, bringing into sharper focus a new set of fundamental questions that Martin Rees addresses in this book. Why is the universe expanding the way it is? What were the 'seeds' that caused galaxies, clusters and superclusters to form? What is the nature of 'dark matter'? What happened in the very early universe? The latest exciting advances and theories are discussed, while maintaining a clear distinction between aspects that now have a firm empirical basis and those that remain speculative.

Bolstered by unassailable science and delivered in eloquent style, "Our Final Hour"'s provocative argument that humanity has a mere 5050 chance of surviving the next century has struck a chord with readers, reviewers, and opinion-makers everywhere. Rees's vision of our immediate future is both a work of stunning scientific originality and a humanistic clarion call on behalf of the future of life.
Popular cosmologist Martin Rees of Cambridge University traces the essential features of the physical cosmos to six numbers imprinted in the Big Bang, and argues that if a single one were untuned, there would be no stars and no life.
In this landmark book, one of the twentieth century's greatest astronomers presents scientific evidence that our vast universe may be only a grain of sand on the infinite cosmic shore.It is now widely accepted that our universe exploded around 15 billion years ago from an unimaginably energetic initial event: the big bang. As the primordial material expanded and cooled, it evolved into the exquisite patterns of stars and galaxies we now observe. The mix of energy and radiation that characterizes our universe was imprinted in that initial instant,as were the binding forces of nuclear physics and gravity that controlled our universe's evolution.The experimental triumphs and theoretical insights of recent years,from the detection of neutrinos from exploding stars to the search for extraterrestrial life,offer the most dramatic enlargement in our concept of the universe since astronomers first realized the sun's true place among the stars. In this illuminating work, Sir Martin Rees, Britain's Astronomer Royal and one of the most creative and original of contemporary scientists, draws these advances together with up-to-the-minute research on black holes, dark matter, and nucleosynthesis of the elements. He also sheds light on some of the personalities behind the science, offering first-hand impressions of Subrahmanyan Chandrasekhar, Stephen Hawking, John Archibald Wheeler, and Fred Hoyle, among others.With stunning clarity, Professor Rees argues that a family,even an infinity,of universes may have been created, each by its own big bang, and each acquiring a distinctive imprint and its own laws of physics. These baby universes will either live out their immense cosmic cycle, or die because those laws do not allow them to achieve longevity.Our "home universe," then, is just one element in a cosmic archipelago where impassable barriers prohibit communication between the islands. But, as Rees demonstrates, our universe is an exceptional member of this infinite ensemble, for it is still near the beginning of a fascinating evolutionary process that will end either in the heat-death of external expansion, or in what scientists call a "big crunch." Most remarkable of all, our universe contains creatures able to observe it. The multi-universe revolution in cosmological thought limned by Rees casts a piercing light on man's place in the cosmos, and argues that the conditions permitting the evolution of life stand on the razor's edge between a dead universe and one filled with living beings.
