What happened before the primordial fire of the Big Bang: a theory about the ultimate origin of the universe. In the beginning was the Big Bang: an unimaginably hot fire almost fourteen billion years ago in which the first elements were forged. The physical theory of the hot nascent universe—the Big Bang—was one of the most consequential developments in twentieth-century science. And yet it leaves many questions unanswered: Why is the universe so big? Why is it so old? What is the origin of structure in the cosmos? In An Infinity of Worlds, physicist Will Kinney explains a more recent theory that may hold the answers to these questions and even explain the ultimate origins of the universe: cosmic inflation, before the primordial fire of the Big Bang. Kinney argues that cosmic inflation is a transformational idea in cosmology, changing our picture of the basic structure of the cosmos and raising unavoidable questions about what we mean by a scientific theory. He explains that inflation is a remarkable unification of inner space and outer space, in which the physics of the very large (the cosmos) meets the physics of the very small (elementary particles and fields), closing in a full circle at the first moment of time. With quantum uncertainty its fundamental feature, this new picture of cosmic origins introduces the possibility that the origin of the universe was of a quantum nature. Kinney considers the consequences of eternal cosmic inflation. Can we come to terms with the possibility that our entire observable universe is one of infinitely many, forever hidden from our view?

'Science has never had an advocate quite like David Deutsch ... A computational physicist on a par with his touchstones Alan Turing and Richard Feynman, and a philosopher in the line of his greatest hero, Karl Popper. His arguments are so clear that to read him is to experience the thrill of the highest level of discourse available on this planet and to understand it' Peter Forbes, Independent In our search for truth, how far have we advanced? This uniquely human quest for good explanations has driven amazing improvements in everything from scientific understanding and technology to politics, moral values and human welfare. But will progress end, either in catastrophe or completion - or will it continue infinitely? In this profound and seminal book, David Deutsch explores the furthest reaches of our current understanding, taking in the Infinity Hotel, supernovae and the nature of optimism, to instill in all of us a wonder at what we have achieved - and the fact that this is only the beginning of humanity's infinite possibility. 'This is Deutsch at his most ambitious, seeking to understand the implications of our scientific explanations of the world ... I enthusiastically recommend this rich, wide-ranging and elegantly written exposition of the unique insights of one of our most original intellectuals' Michael Berry, Times Higher Education Supplement 'Bold ... profound ... provocative and persuasive' Economist 'David Deutsch may well go down in history as one of the great scientists of our age' Scotsman

A Leading Figure in the Development of the New Cosmology Explains What It All Means Among his peers, Alex Vilenkin is regarded as one of the most imaginative and creative cosmologists of our time. His contributions to our current understanding of the universe include a number of novel ideas, two of which—eternal cosmic inflation and the quantum creation of the universe from nothing—have provided a scientific foundation for the possible existence of multiple universes. With this book—his first for the general reader—Vilenkin joins another select group: the handful of first-rank scientists who are equally adept at explaining their work to nonspecialists. With engaging, well-paced storytelling, a droll sense of humor, and a generous sprinkling of helpful cartoons, he conjures up a bizarre and fascinating new worldview that—to paraphrase Niels Bohr—just might be crazy enough to be true.

The third book in the trilogy--following "Fleet of Worlds" and "Juggler of Worlds--Destroyer of Worlds" is set 200 years before the discovery of Ringworld.

The classic science fiction trilogy by the author of The Chronicles of Narnia at last available in a new A-format boxed set The Cosmic Trilogy is a remarkable work of fantasy, demonstrating yet again the powerful imagination of C.S Lewis. OUT OF THE SILENT PLANET Dr Ransom, a Cambridge academic, is abducted and taken on a spaceship to the red planet of Malacandra, which he knows as Mars. His captors are plotting to plunder the planet's treasures and plan to offer Ransom as a sacrifice to the creatures who live there. Ransom discovers he has come from the 'silent planet' -- Earth -- whose tragic story is known throughout the universe...PERELANDRA Dr Ransom is called to the paradise planet of Perelandra, or Venus, which turns out to be a beautiful Eden-like world. He is horrified to find that his old enemy, Dr Weston, has also arrived and is putting him in grave peril once more. As the mad Weston's body is taken over by the forces of evil, Ransom engages in a desperate struggle to save the innocence of Perelandra...T decapitated head, Jane Studdock sees the same face in a newspaper and has the growing feeling that she is being warned of something real and ominous. Meanwhile, her husband Mark has been enticed to join the National Institute for Co-ordinated Experiments, which aims to control human society. As he is drawn into the sinister organization, he discovers the truth about his wife's dreams, while she seeks helps at a community called St Anne's, led by the charismatic Dr Ransom...

Paul Davies explains the significance of the amazing quantum universe, where fact is stranger than any science fiction. He takes us into a world where commonsense notions of space, time, and causality must be left behind as the realm of solid matter dissolves into vibrating patterns of ghostly energy, and where mind and matter are interwoven in a subtle and holistic manner. An Australian physicist and author of GOD AND THE NEW PHYSICS, Davies writes for the lay reader in simple language.

In 1584, while living in the household of Michel de Castelnau, the French Ambassador to the court of Queen Elizabeth of England, Giordano Bruno completed three books of cosmological dialogues: The Ash Wednesday Supper; On Cause, Principle and Unity; and the current volume, On the Infinite, the Universe and the Worlds. Drawing on the work of Lucretius, Nicholas da Cusa, Nicholas Copernicus and others, Bruno developed the theory of an infinitely extensive universe, filled with stars like our sun and planets like our own.Giordano Bruno's heretical ideas and forceful personality led to a turbulent life in which he travelled to most of the great academic and cultural centers of Europe, culminating in his trial and execution by the Roman Inquisition in 1600.Recently, this work and Giordano Bruno were referenced in the new series of Cosmos.
