Book Description
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.

Book Description
PaGaian Cosmology brings together a religious practice of seasonal ritual based in a contemporary scientific sense of the cosmos and female imagery for the Sacred. The author situates this original synthesis in her context of being female and white European transplanted to the Southern Hemisphere. Her sense of alienation from her place, which is personal, cultural and cosmic, fires a cosmology that re-stories Goddess metaphor of Virgin-Mother-Crone as a pattern of Creativity, which unfolds the cosmos, manifests in Earth's life, and may be known intimately. PaGaian Cosmology is an ecospirituality grounded in indigenous Western religious celebration of the Earth-Sun annual cycle. By linking to story of the unfolding universe this practice can be deepened, and a sense of the Triple Goddess-central to the cycle and known in ancient cultures-developed as a dynamic innate to all being. The ritual scripts and the process of ritual events presented here, may be a journey into self-knowledge through personal, communal and ecological story: the self to be known is one that is integral with place. PaGaian Cosmology may be used as a resource for individuals or groups seeking new forms of devotional expression and an Earth-based pathway to wisdom within.

Book Description
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.

Book Description
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? What fundamental laws govern our universe?This book describes new discoveries and offers remarkable insights into these fundamental questions. There are deep connections between stars and atoms, between the cosmos and the microworld. Just six numbers, imprinted in the "big bang," determine the essential features of our entire physical world. Moreover, cosmic evolution is astonishingly sensitive to the values of these numbers. If any one of them were "untuned," there could be no stars and no life. This realization offers a radically new perspective on our universe, our place in it, and the nature of physical laws.

Book Description
Are we more than stardust? Is the appearance of the fragile Earth in the vast universe more than an accident? Are we not children of a Spirit that pervades the dust, rejuvenates life, and embraces the ever-evolving universe? Is there a cosmic Spirit that wants us to awaken to a consciousness of universal meaning, sacred purpose, and mutual friendship with all beings? This book answers these questions with a spirituality of the numinous in our relation to the elements of the Earth in the matrix of the multiverse by taking you on a journey through nine paths and nineteen meditations of awakening. Not bound by any religion, but in deep appreciation of the religious and spiritual heritage of human encounters with the divine depth of existence in our selves and in nature, they invite you to become sojourners by engaging the most profound embodiments of the intangible Spirit by which it facilitates its own materialization in the cosmos and our spiritualization of the cosmos. Use--says this Spirit--the stardust that you are to become a spirit-faring species in an eternal journey of the cosmos to realize its ultimate motive of existence--the attraction of love!

Book Description
Are humans a galactic oddity, or will complex life with human abilities develop on planets with environments that remain habitable for long enough? In a clear, jargon-free style, two leading researchers in the burgeoning field of astrobiology critically examine the major evolutionary steps that led us from the distant origins of life to the technologically advanced species we are today. Are the key events that took life from simple cells to astronauts unique occurrences that would be unlikely to occur on other planets? By focusing on what life does - it's functional abilities - rather than specific biochemistry or anatomy, the authors provide plausible answers to this question. Systematically exploring the various pathways that led to the complex biosphere we experience on planet Earth, they show that most of the steps along that path are likely to occur on any world hosting life, with only two exceptions: One is the origin of life itself – if this is a highly improbable event, then we live in a rather “empty universe”. However, if this isn’t the case, we inevitably live in a universe containing a myriad of planets hosting complex as well as microbial life - a “cosmic zoo”. The other unknown is the rise of technologically advanced beings, as exemplified on Earth by humans. Only one technological species has emerged in the roughly 4 billion years life has existed on Earth, and we don’t know of any other technological species elsewhere. If technological intelligence is a rare, almost unique feature of Earth's history, then there can be no visitors to the cosmic zoo other than ourselves. Schulze-Makuch and Bains take the reader through the history of life on Earth, laying out a consistent and straightforward framework for understanding why we should think that advanced, complex life exists on planets other than Earth. They provide a unique perspective on the question that puzzled the human species for centuries: are we alone?

Book Description
Many environmentalists think going into space detracts from solving problems here on Earth. Many astrophysicists feel environmentalism hampers their exploration and settlement of space. Actually environmentalism and space exploration have one and the same objective, argues leading astro-biologist Professor Charles Cockell: to ensure humanity has a home. Cockell calls for a fusion of the two movements as the only way forward. The technologies we develop to live sustainably on Earth, such as wind and solar power, will also establish humanity in space. The exploration of space will provide new resources and skills for the protection of the Earth's environment. For example, studying extreme environments on Earth is helping us to look for life on Mars and satellites orbiting Earth are helping track hurricanes and protect people from natural disasters. There are many books on environmentalism and many on space faring. Space On Earth is the first to provide a new vision of humanity's future bringing these two goals together.
