BOOK EXCERPT:

One of the world's leading physicists questions some of the most fashionable ideas in physics today, including string theory What can fashionable ideas, blind faith, or pure fantasy possibly have to do with the scientific quest to understand the universe? Surely, theoretical physicists are immune to mere trends, dogmatic beliefs, or flights of fancy? In fact, acclaimed physicist and bestselling author Roger Penrose argues that researchers working at the extreme frontiers of physics are just as susceptible to these forces as anyone else. In this provocative book, he argues that fashion, faith, and fantasy, while sometimes productive and even essential in physics, may be leading today's researchers astray in three of the field's most important areas—string theory, quantum mechanics, and cosmology. Arguing that string theory has veered away from physical reality by positing six extra hidden dimensions, Penrose cautions that the fashionable nature of a theory can cloud our judgment of its plausibility. In the case of quantum mechanics, its stunning success in explaining the atomic universe has led to an uncritical faith that it must also apply to reasonably massive objects, and Penrose responds by suggesting possible changes in quantum theory. Turning to cosmology, he argues that most of the current fantastical ideas about the origins of the universe cannot be true, but that an even wilder reality may lie behind them. Finally, Penrose describes how fashion, faith, and fantasy have ironically also shaped his own work, from twistor theory, a possible alternative to string theory that is beginning to acquire a fashionable status, to "conformal cyclic cosmology," an idea so fantastic that it could be called "conformal crazy cosmology." The result is an important critique of some of the most significant developments in physics today from one of its most eminent figures.

BOOK EXCERPT:

What came before the Big Bang? How did the universe begin and must it inevitably end? In this remarkable book Roger Penrose brilliantly illuminates some of the deepest mysteries of the universe. Cycles of Time contains a penetrating analysis of the second law of thermodynamics - according to which the 'randomness' of our world is continually increasing - and a thorough examination of the light-cone geometry of space-time. It combines these two central themes to show how the expected ultimate fate of our accelerating, expanding universe can actually be reinterpreted as the 'big bang' of a new one. Presenting various standard and non-standard cosmological models, discussing black holes in depth as well as taking in the role of the cosmic microwave background along the way, Roger Penrose argues that the Big Bang was not actually the beginning of everything - nor will it signal the end. ‘Science needs more people like Penrose, willing and able to point out the flaws in fashionable models from a position of authority, and to signpost alternative roads to follow’ Independent

BOOK EXCERPT:

Today we are blessed with two extraordinarily successful theories of physics. The first is Albert Einstein's general theory of relativity, which describes the large-scale behaviour of matter in a curved spacetime. This theory is the basis for the standard model of big bang cosmology. The discovery of gravitational waves at the LIGO observatory in the US (and then Virgo, in Italy) is only the most recent of this theory's many triumphs. The second is quantum mechanics. This theory describes the properties and behaviour of matter and radiation at their smallest scales. It is the basis for the standard model of particle physics, which builds up all the visible constituents of the universe out of collections of quarks, electrons and force-carrying particles such as photons. The discovery of the Higgs boson at CERN in Geneva is only the most recent of this theory's many triumphs. But, while they are both highly successful, these two structures leave a lot of important questions unanswered. They are also based on two different interpretations of space and time, and are therefore fundamentally incompatible. We have two descriptions but, as far as we know, we've only ever had one universe. What we need is a quantum theory of gravity. Approaches to formulating such a theory have primarily followed two paths. One leads to String Theory, which has for long been fashionable, and about which much has been written. But String Theory has become mired in problems. In this book, Jim Baggott describes ": an approach which takes relativity as its starting point, and leads to a structure called Loop Quantum Gravity. Baggott tells the story through the careers and pioneering work of two of the theory's most prominent contributors, Lee Smolin and Carlo Rovelli. Combining clear discussions of both quantum theory and general relativity, this book offers one of the first efforts to explain the new quantum theory of space and time.

BOOK EXCERPT:

A breathtaking vision of a utopian future on Mars by one of science fiction’s most renowned authors In the middle decades of the twenty-first century, the corporate powers on Earth have established a thriving colony on Mars as an alternative to life on the overpopulated, war-torn, ecologically ravaged home planet. But when the economy of EUPACUS—Earth’s collective industrialized nations—collapses, all contact between the two worlds abruptly ceases, and the Martian pioneers are left to fend for themselves. Led by Tom Jeffries, a philosopher and a visionary, the colonists now face a twofold challenge: No longer supported and subsidized by Earthbound interests, they must somehow form a working planetary alliance to create a new society based firmly in freedom and fairness for all while at the same time eliminating war, hunger, hatred, environmental abuse, and other former scourges of humanity. But first and foremost, they must survive. Brian W. Aldiss, a Hugo and Nebula Award–winning Grand Master of Science Fiction, presents a vision for the future that is startling, uplifting, and endlessly exciting. Written in collaboration with noted mathematician and physicist Roger Penrose—and with essential input from international law expert Laurence Lustgarten—Aldiss’s remarkable White Mars opens a window onto a relentlessly thrilling and gloriously possible tomorrow.

BOOK EXCERPT:

What is the relationship between religion and multi-player online roleplaying games? Are such games simply a secular distraction from traditional religious practices, or do they in fact offer a different route to the sacred? In eGods, a leading scholar in the study of virtual gameworlds takes an in-depth look at the fantasy religions of 41 games and arrives at some surprising conclusions. William Sims Bainbridge investigates all aspects of the gameworlds' religious dimensions: the focus on sacred spaces; the prevalence of magic; the fostering of a tribal morality by both religion and rules programmed into the game; the rise of cults and belief systems within the gameworlds (and how this relates to cults in the real world); the predominance of polytheism; and, of course, how gameworld religions depict death. As avatars are multiple and immortal, death is merely a minor setback in most games. Nevertheless, much of the action in some gameworlds centers on the issue of mortality and the problematic nature of resurrection. Examining EverQuest II, Lord of the Rings Online, Rift, World of Warcraft, Star Wars: The Old Republic, and many others, Bainbridge contends that gameworlds offer a new perspective on the human quest, one that combines the arts, simulates many aspects of real life, and provides meaningful narratives about achieving goals by overcoming obstacles. Indeed, Bainbridge suggests that such games take us back to those ancient nights around the fire, when shadows flickered and it was easy to imagine the monsters conjured by the storyteller lurking in the forest. Arguing that gameworlds reintroduce a curvilinear model of early religion, where today as in ancient times faith is inseparable from fantasy, eGods shows how the newest secular technology returns us to the very origins of religion so that we might "arrive where we started and know the place for the first time."
