The Extravagant Universe tells the story of a remarkable adventure of scientific discovery. One of the world's leading astronomers, Robert Kirshner, takes readers inside a lively research team on the quest that led them to an extraordinary cosmological discovery: the expansion of the universe is accelerating under the influence of a dark energy that makes space itself expand. In addition to sharing the story of this exciting discovery, Kirshner also brings the science up-to-date in a new epilogue. He explains how the idea of an accelerating universe--once a daring interpretation of sketchy data--is now the standard assumption in cosmology today. This measurement of dark energy--a quality of space itself that causes cosmic acceleration--points to a gaping hole in our understanding of fundamental physics. In 1917, Einstein proposed the "cosmological constant" to explain a static universe. When observations proved that the universe was expanding, he cast this early form of dark energy aside. But recent observations described first-hand in this book show that the cosmological constant--or something just like it--dominates the universe's mass and energy budget and determines its fate and shape. Warned by Einstein's blunder, and contradicted by the initial results of a competing research team, Kirshner and his colleagues were reluctant to accept their own result. But, convinced by evidence built on their hard-earned understanding of exploding stars, they announced their conclusion that the universe is accelerating in February 1998. Other lines of inquiry and parallel supernova research now support a new synthesis of a cosmos dominated by dark energy but also containing several forms of dark matter. We live in an extravagant universe with a surprising number of essential ingredients: the real universe we measure is not the simplest one we could imagine.

What is a black hole? Could we survive a visit to one? Perhaps even venture inside? What would we find? Have we yet discovered any real black holes? And what do black holes teach us about what physicist John Archibald Wheeler called “the deep, happy, mysteries of the universe”? These are just a few of the tantalizing questions examined in this jargon-free review of one of the most fascinating topics in modern science. In search of the answers, we trace a star from its birth to its death throes, take a fabulous hypothetical journey to the border of a black hole and beyond, spend time with some of the world’s leading theoretical physicists and observational astronomers scanning the cosmos for evidence of real black holes, and take a whimsical look at some of the wild ideas black holes have inspired.

A eureka-inspiring book that will change your view of the world as you know it. In this compilation of the biggest scientific discoveries of the last decades, Pere Estupinyà clearly and thoughtfully explains to his readers the most innovative ideas sprouting from the world's top scientists' brains... How does the brain act when we are hung-over? Can we trick our body into falling in love? What's the world going to be like in thirty years? All of this, and much more, is explained in this indispensable book for science lovers and the curious-minded. In The Brain Snatcher, the author accesses the world's most prestigious laboratories in order to steal the knowledge of this century's heroes -scientists- and share it with his readers. Through entertaining stories, the reader gets acquainted with the hottest debates in neuroscience, cosmology, genetics, human psychology, sociology of science, and climate change. Moreover, the brain snatcher follows the flu virus through the body; steps into a brain scanner to check if it's capable of detecting his own lies; delves into the frictions between religion and creationism; asks his own hormones why he falls in love; surrenders to the Chaos theory, and sees how disastrous the brain is when it comes to making a thorough decision. He also gets to understand why his pupils dilate when he is having an orgasm; finds the origins of superstitions, analyzes why magazines like Science or Nature make more mistakes than other so-called minor magazines, discovers the reasons that can lead an endearing scientist to keep on investigating until he is 96, and goes crazy trying to figure out what things like antimatter or quantum entanglement are. A buffet of knowledge for those without a science degree, but who are curious about the whys, whats and hows of science!

WINNER OF THE 1996 WILLIAM HILL SPORTS BOOK OF THE YEAR PRIZE. In the early 1990s, Donald McRae set out to discover the truth about the intense and forbidding world of professional boxing. Travelling around the States and Britain, he was welcomed into the inner sanctums of some of the greatest fighters of the period - men such as Mike Tyson, Chris Eubank, Oscar de la Hoya, Frank Bruno, Evander Holyfield and Naseem Hamed among them. They opened up to him, revealing unforgettable personal stories from both inside and outside the ring, and explaining why it is that some are driven to compete in this most brutal of sports, risking their health and even their lives. The result is a classic account of boxing that remains as fresh and entertaining as when it was first published almost 20 years ago. McRae approaches his subjects with wit, compassion and insight, and the result was a book that was a deserved winner of the William Hill Sports Book of the Year prize.

From Brian Greene, one of the world’s leading physicists and author the Pulitzer Prize finalist The Elegant Universe, comes a grand tour of the universe that makes us look at reality in a completely different way. Space and time form the very fabric of the cosmos. Yet they remain among the most mysterious of concepts. Is space an entity? Why does time have a direction? Could the universe exist without space and time? Can we travel to the past? Greene has set himself a daunting task: to explain non-intuitive, mathematical concepts like String Theory, the Heisenberg Uncertainty Principle, and Inflationary Cosmology with analogies drawn from common experience. From Newton’s unchanging realm in which space and time are absolute, to Einstein’s fluid conception of spacetime, to quantum mechanics’ entangled arena where vastly distant objects can instantaneously coordinate their behavior, Greene takes us all, regardless of our scientific backgrounds, on an irresistible and revelatory journey to the new layers of reality that modern physics has discovered lying just beneath the surface of our everyday world.

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.

Two world-renowned scientists present an audacious new vision of the cosmos that “steals the thunder from the Big Bang theory.” —Wall Street Journal The Big Bang theory—widely regarded as the leading explanation for the origin of the universe—posits that space and time sprang into being about 14 billion years ago in a hot, expanding fireball of nearly infinite density. Over the last three decades the theory has been repeatedly revised to address such issues as how galaxies and stars first formed and why the expansion of the universe is speeding up today. Furthermore, an explanation has yet to be found for what caused the Big Bang in the first place. In Endless Universe, Paul J. Steinhardt and Neil Turok, both distinguished theoretical physicists, present a bold new cosmology. Steinhardt and Turok “contend that what we think of as the moment of creation was simply part of an infinite cycle of titanic collisions between our universe and a parallel world” (Discover). They recount the remarkable developments in astronomy, particle physics, and superstring theory that form the basis for their groundbreaking “Cyclic Universe” theory. According to this theory, the Big Bang was not the beginning of time but the bridge to a past filled with endlessly repeating cycles of evolution, each accompanied by the creation of new matter and the formation of new galaxies, stars, and planets. Endless Universe provides answers to longstanding problems with the Big Bang model, while offering a provocative new view of both the past and the future of the cosmos. It is a “theory that could solve the cosmic mystery” (USA Today).

In the first chapters the author describes how our knowledge of the position of Earth in space and time has developed, thanks to the work of many generations of astronomers and physicists. He discusses how our position in the Galaxy was discovered, and how in 1929, Hubble uncovered the fact that the Universe is expanding, leading to the picture of the Big Bang. He then explains how astronomers have found that the laws of physics that were discovered here on Earth and in the Solar System (the laws of mechanics, gravity, atomic physics, electromagnetism, etc.) are valid throughout the Universe. This is illustrated by the fact that all matter in the Universe consists of atoms of the same chemical elements that we know on Earth. This unity is all the more surprising when one realizes that in the original Big Bang theory, different parts of the Universe could never have communicated with each other. It then is a mystery how they could have shared the same physical laws. This problem was solved by the introduction of the idea of inflation, a phase of extremely rapid expansion of the Universe during the first fraction of a second following the Big Bang. The author explains how the unity of the Universe finds its origin in the Big Bang prior to inflation. The book addresses the many fundamental questions about the Universe and its contents from the perspective of the Big Bang: the formation of structure in the Universe, the questions of the mysterious dark matter and dark energy, the possibilities of other Universes (the Multiverse) and of the existence of intelligent life elsewhere in the Universe.
