… [Greene's] excitement for science on the threshold of vital breakthroughs is supremely contagious. The Fabric of the Cosmos is as dazzling as it is tough, and it beautifully reflects this theoretician's ardor for his work. In interviews he is sometimes asked where the next generation of physicists will come from. One clear answer: from the brain-teasing, exhilarating study of books like this. — Janet Maslin
String theory is a recent development in physics that, by positing that all which exists is composed of infinitesimally small vibrating loops of energy, seeks to unify Einstein's theories and those of quantum mechanics into a so-called "theory of everything." In 1999, Greene, one of the world's leading physicists, published The Elegant Universe (Norton), a popular presentation of string theory that became a major bestseller and, last fall, a highly rated PBS/Nova series. The strength of the book resided in Greene's unparalleled (among contemporary science writers) ability to translate higher mathematics (the language of physics) and its findings into everyday language and images, through adept use of metaphor and analogy, and crisp, witty prose. The same virtues adhere to this new book, which offers a lively view of human understanding of space and time, an understanding of which string theory is an as-yet unproven advance. To do this, Greene takes a roughly chronological approach, beginning with Newton, moving through Einstein and quantum physics, and on to string theory and its hypotheses (that there are 11 dimensions, ten of space and one of time; that there may be an abundance of parallel universes; that time travel may be possible, and so on) and imminent experiments that may test some of its tenets. None of this is easy reading, mostly because the concepts are tough to grasp and Greene never seems to compromise on accuracy. Eighty-five line drawings ease the task, however, as does Greene's felicitous narration; most importantly, though, Greene not only makes concepts clear but explains why they matter. He opens the book with a discussion of Camus's The Myth of Sisyphus, setting a humanistic tone that he sustains throughout. This is popular science writing of the highest order, with copious endnotes that, unlike the text, include some math. (Feb. 16) Forecast: With a first printing of 125,000, Knopf clearly hopes this title, a main selection of BOMC, will at least match the sales of The Elegant Universe. Greene, a charismatic speaker, is going all out for the book, with a 14-city author tour and much major media, including an appearance on Letterman. Simultaneous Random House Audio editions will extend the book's reach: expect high interest and big sales. Copyright 2004 Reed Business Information.
Greene, the critically acclaimed author of The Elegant Universe and one of the world's leading string theorists, has written yet another thought-provoking account of where we are in our understanding of the universe. He tells the story of how generations of physicists have searched for the holy grail of physics, i.e., the single set of universal laws that govern the universe. However, the principal characters are not the physicists themselves but the theories that they developed, in particular, general relativity and quantum mechanics. Greene explores the string theory-mating dance between the two in simple but elegant language that titillates the mind. Frogs in bowls, falling eggs, loaves of bread, pennies on balloons, ping pong balls in molasses, and babushka dolls are just some of the analogies used to explain complex concepts cleverly. After reading this book, you will never look at a starry night sky the same way again. Strongly recommended for most science collections. [Previewed in Prepub Alert, LJ 10/1/03.]-James A.

Stephen Hawking may be the more renowned scientist, but when it comes to explaining cutting-edge physics to the lay reader, he comes second to Brian Greene. This recording introduces superstring theory, an attempt to solve one of science’s most perplexing problems: how to reconcile general relativity and quantum mechanics. Not only is Greene a superb stylist who introduces these concepts without jargon or mathematics, he also has a grab bag of imaginative analogies for ideas that are impossible to visualize--such as the extra spatial dimensions that superstring theory requires. Erik Davies may not be a physicist, but he’s entirely comfortable with the material, and he delivers it at just the right pace. Most importantly, he feeds on Greene’s enthusiasm and passes it along to the listener. D.B. © AudioFile 2004, Portland, Maine

Chapter 1: Roads to Reality
SPACE, TIME, AND WHY THINGS ARE AS THEY ARE
None of the books in my father's dusty old bookcase were forbidden. Yet while I was growing up, I never saw anyone take one down. Most were massive tomes–a comprehensive history of civilization, matching volumes of the great works of western literature, numerous others I can no longer recall–that seemed almost fused to shelves that bowed slightly from decades of steadfast support. But way up on the highest shelf was a thin little text that, every now and then, would catch my eye because it seemed so out of place, like Gulliver among the Brobdingnagians. In hindsight, I'm not quite sure why I waited so long before taking a look. Perhaps, as the years went by, the books seemed less like material you read and more like family heirlooms you admire from afar. Ultimately, such reverence gave way to teenage brashness. I reached up for the little text, dusted it off, and opened to page one. The first few lines were, to say the least, startling.
"There is but one truly philosophical problem, and that is suicide," the text began. I winced. "Whether or not the world has three dimensions or the mind nine or twelve categories," it continued, "comes afterward"; such questions, the text explained, were part of the game humanity played, but they deserved attention only after the one true issue had been settled. The book was The Myth of Sisyphus and was written by the Algerian-born philosopher and Nobel laureate Albert Camus. After a moment, the iciness of his words melted under the light of comprehension. Yes, of course, I thought. You can ponder this or analyze that till the cows comehome, but the real question is whether all your ponderings and analyses will convince you that life is worth living. That's what it all comes down to. Everything else is detail.
My chance encounter with Camus' book must have occurred during an especially impressionable phase because, more than anything else I'd read, his words stayed with me. Time and again I'd imagine how various people I'd met, or heard about, or had seen on television would answer this primary of all questions. In retrospect, though, it was his second assertion –regarding the role of scientific progress–that, for me, proved particularly challenging. Camus acknowledged value in understanding the structure of the universe, but as far as I could tell, he rejected the possibility that such understanding could make any difference to our assessment of life's worth. Now, certainly, my teenage reading of existential philosophy
was about as sophisticated as Bart Simpson's reading of Romantic poetry, but even so, Camus' conclusion struck me as off the mark. To this aspiring physicist, it seemed that an informed appraisal of life absolutely required a full understanding of life's arena–the universe. I remember thinking that if our species dwelled in cavernous outcroppings buried deep underground and so had yet to discover the earth's surface, brilliant sunlight, an ocean breeze, and the stars that lie beyond, or if evolution had proceeded along a different pathway and we had yet to acquire any but the sense of touch, so everything we knew came only from our tactile impressions of our immediate environment, or if human mental faculties stopped developing during early childhood so our emotional and analytical skills never progressed beyond those of a five-year-old–in short, if our experiences painted but a paltry portrait of reality–our appraisal of life would be thoroughly compromised. When we finally found our way to earth's surface, or when we finally gained the ability to see, hear, smell, and taste, or when our minds were finally freed to develop as they ordinarily do, our collective view of life and the cosmos would, of necessity, change radically. Our previously compromised grasp of reality would have shed a very different light on that most fundamental of all philosophical questions.
But, you might ask, what of it? Surely, any sober assessment would conclude that although we might not understand everything about the universe–every aspect of how matter behaves or life functions–we are privy to the defining, broad-brush strokes gracing nature's canvas. Surely, as Camus intimated, progress in physics, such as understanding the number of space dimensions; or progress in neuropsychology, such as understanding all the organizational structures in the brain; or, for that matter, progress in any number of other scientific undertakings may fill in important details, but their impact on our evaluation of life and reality would be minimal. Surely, reality is what we think it is; reality is revealed to us by
our experiences.
To one extent or another, this view of reality is one many of us hold, if only implicitly. I certainly find myself thinking this way in day-to-day life; it's easy to be seduced by the face nature reveals directly to our senses. Yet, in the decades since first encountering Camus' text, I've learned that modern science tells a very different story. The overarching lesson that has emerged from scientific inquiry over the last century is that human experience is often a misleading guide to the true nature of reality. Lying just beneath the surface of the everyday is a world we'd hardly recognize. Followers of the occult, devotees of astrology, and those who hold to religious principles that speak to a reality beyond experience have, from widely varying perspectives, long since arrived at a similar conclusion. But that's not what I have in mind. I'm referring to the work of ingenious innovators and tireless researchers–the men and women of science–who have peeled back layer after layer of the cosmic onion, enigma by enigma, and revealed a universe that is at once surprising, unfamiliar, exciting, elegant, and thoroughly unlike what anyone ever expected.
These developments are anything but details. Breakthroughs in physics have forced, and continue to force, dramatic revisions to our conception of the cosmos. I remain as convinced now as I did decades ago that Camus rightly chose life's value as the ultimate question, but the insights of modern physics have persuaded me that assessing life through the lens of everyday experience is like gazing at a van Gogh through an empty Coke bottle. Modern science has spearheaded one assault after another on evidence gathered from our rudimentary perceptions, showing that they often yield a clouded conception of the world we inhabit. And so whereas Camus separated out physical questions and labeled them secondary, I've become convinced that they're primary. For me, physical reality both sets the arena and provides the illumination for grappling with Camus' question. Assessing existence while failing to embrace the insights of modern physics would be like wrestling in the dark with an unknown opponent. By deepening our understanding of the true nature of physical reality, we profoundly reconfigure our sense of ourselves and our experience of the universe.
The central concern of this book is to explain some of the most prominent and pivotal of these revisions to our picture of reality, with an intense focus on those that affect our species' long-term project to understand space and time. From Aristotle to Einstein, from the astrolabe to the Hubble Space Telescope, from the pyramids to mountaintop observatories,
space and time have framed thinking since thinking began. With the advent of the modern scientific age, their importance has been tremendously heightened. Over the last three centuries, developments in physics have revealed space and time as the most baffling and most compelling concepts, and as those most instrumental in our scientific analysis of the universe. Such developments have also shown that space and time top the list of age-old scientific constructs that are being fantastically revised by cutting-edge research.
To Isaac Newton, space and time simply were–they formed an inert, universal cosmic stage on which the events of the universe played themselves out. To his contemporary and frequent rival Gottfried Wilhelm von Leibniz, "space" and "time" were merely the vocabulary of relations between where objects were and when events took place. Nothing more. But to Albert Einstein, space and time were the raw material underlying reality. Through his theories of relativity, Einstein jolted our thinking about space and time and revealed the principal part they play in the evolution of the universe. Ever since, space and time have been the sparkling jewels of physics. They are at once familiar and mystifying; fully understanding space and time has become physics' most daunting challenge and sought-after prize.
The developments we'll cover in this book interweave the fabric of space and time in various ways. Some ideas will challenge features of space and time so basic that for centuries, if not millennia, they've seemed beyond questioning. Others will seek the link between our theoretical understanding of space and time and the traits we commonly experience. Yet others will raise questions unfathomable within the limited confines of ordinary perceptions.
We will speak only minimally of philosophy (and not at all about suicide and the meaning of life). But in our scientific quest to solve the mysteries of space and time, we will be resolutely unrestrained. From the universe's smallest speck and earliest moments to its farthest reaches and most distant future, we will examine space and time in environments familiar and far-flung, with an unflinching eye seeking their true nature. As the story of space and time has yet to be fully written, we won't arrive at any final assessments. But we will encounter a series of developments–some intensely strange, some deeply satisfying, some experimentally verified, some thoroughly speculative–that will show how close we've come to wrapping our minds around the fabric of the cosmos and touching the true texture of reality.
Classical Reality
Historians differ on exactly when the modern scientific age began, but certainly by the time Galileo Galilei, René Descartes, and Isaac Newton had had their say, it was briskly under way. In those days, the new scientific mind-set was being steadily forged, as patterns found in terrestrial and astronomical data made it increasingly clear that there is an order to all the comings and goings of the cosmos, an order accessible to careful reasoning and mathematical analysis. These early pioneers of modern scientific thought argued that, when looked at the right way, the happenings in the universe not only are explicable but predictable. The power of science to foretell aspects of the future–consistently and quantitatively–had been revealed.
Early scientific study focused on the kinds of things one might see or experience in everyday life. Galileo dropped weights from a leaning tower (or so legend has it) and watched balls rolling down inclined surfaces; Newton studied falling apples (or so legend has it) and the orbit of the moon. The goal of these investigations was to attune the nascent scientific ear to nature's harmonies. To be sure, physical reality was the stuff of experience, but the challenge was to hear the rhyme and reason behind the rhythm and regularity. Many sung and unsung heroes contributed to the rapid and impressive progress that was made, but Newton stole the show. With a handful of mathematical equations, he synthesized everything known about motion on earth and in the heavens, and in so doing, composed the score for what has come to be known as classical physics. In the decades following Newton's work, his equations were developed into an elaborate mathematical structure that significantly extended both their reach and their practical utility. Classical physics gradually became a sophisticated and mature scientific discipline. But shining clearly through all these advances was the beacon of Newton's original insights. Even today, more than three hundred years later, you can see Newton's equations scrawled on introductory-physics chalkboards worldwide, printed on NASA flight plans computing spacecraft trajectories, and embedded within the complex calculations of forefront research. Newton brought a wealth of physical phenomena within a single theoretical framework.
But while formulating his laws of motion, Newton encountered a critical stumbling block, one that is of particular importance to our story (Chapter 2). Everyone knew that things could move, but what about the arena within which the motion took place? Well, that's space, we'd all answer. But, Newton would reply, what is space? Is space a real physical entity or is it an abstract idea born of the human struggle to comprehend the cosmos? Newton realized that this key question had to be answered, because without taking a stand on the meaning of space and time, his equations describing motion would prove meaningless. Understanding requires context; insight must be anchored.
And so, with a few brief sentences in his Principia Mathematica, Newton articulated a conception of space and time, declaring them absolute and immutable entities that provided the universe with a rigid, unchangeable arena. According to Newton, space and time supplied an invisible scaffolding that gave the universe shape and structure. Not everyone agreed. Some argued persuasively that it made little sense to ascribe existence to something you can't feel, grasp, or affect. But the explanatory and predictive power of Newton's equations quieted the critics. For the next two hundred years, his absolute conception of space and time was dogma.
