Richard Gott leads time travel out of the world of H. G. Wells and into the realm of scientific possibility. Building on theories posited by Einstein and advanced by scientists such as Stephen Hawking and Kip Thorne, Gott explains how time travel can actually occur. He describes, with boundless enthusiasm and humor, how travel to the future is not only possible but has already happened, and he contemplates whether travel to the past is also conceivable. Notable not only for its extraordinary subject matter and scientific brilliance, Time Travel in Einstein’s Universe is a delightful and captivating exploration of the surprising facts behind the science fiction of time travel.

    Whether floating in a skiff on the Ganges as the Sun descends behind the funeral pyres of Varanasi, interviewing psychologists in the Norwegian Arctic about the effects of darkness, or watching tomato seedlings in southern Spain being hair-brushed (the better to catch the Sun's rays), Cohen tirelessly pursues his quarry. Drawing on more than seven years of research, he reports from locations in eighteen different countries, including the Novolazarevskaya science station in Antarctica (the coldest place on Earth); the Arizona desert (the sunniest); the Pope's observatory-cum-fortress outside Rome (possible the least accessible); and the crest of Mount Fuji, where--entirely alone--he welcomes the sunrise on the longest day of the year. As he soon discovers, the Sun is present everywhere--in mythology, language, religion, sciences, art, literature, and medicine; in the ocean depths; even atop the Statue of Liberty. Ancient worshippers believed our star was a man with three eyes and four arms, abandoned by his spouse because his brightness made her weary. The early Christians appropriated the halo from sun imagery and saw the cross as an emblem of the Sun and its rays. Galileo was the first to espy blemishes on the solar surface--sunspots--but hid his discoveries for fear of persecution. Einstein helped duplicate the source of the Sun's power to create the atomic bomb; while the "Sun King" Louis XIV, Chairman Mao, Adolf Hitler, and the Japanese emperors all co-opted the Sun to enlarge their authority. Conan Doyle had Sherlock Holmes declare that even thinking about the solar system took up too much space in his brain, while Richard Wagner had Tristan inveigh against daylight as the enemy of romantic love. Packed with interesting figures (the Sun is responsible for 44 percent of the world's tidal energy, and when aligned with the Moon, as at high tide, makes us all minutely taller); extraordinary myths (in India, just a few years ago, pregnant women were still being kept indoors during an eclipse, for fear their babies would be born blind or with cleft palates); and surprising anecdotes (during the Vietnam War, a large number of mines dropped into Haiphong harbor blew up simultaneously in response to a large solar flare), this splendidly illustrated volume is erudite, informative, and supremely entertaining. It not only explains the star that so inspires us, but shows how complex our relations with it have been--and continue to be.

    You experience it passing every day when you watch clocks tick, bread toast, and children grow. But most physicists see things differently, from Newton to Einstein to today’s quantum theorists. For them, time isn’t real. You may think you experience time passing, but they say it’s just an illusion.Lee Smolin, author of the controversial bestseller The Trouble with Physics, argues this limited notion of time is holding physics back. It’s time for a major revolution in scientific thought. The reality of time could be the key to the next big breakthrough in theoretical physics.What if the laws of physics themselves were not timeless? What if they could evolve? Time Reborn offers a radical new approach to cosmology that embraces the reality of time and opens up a whole new universe of possibilties. There are few ideas that, like our notion of time, shape our thinking about literally everything, with major implications for physics and beyond—from climate change to the economic crisis. Smolin explains in lively and lucid prose how the true nature of time impacts our world.

    He looks at the difficult dialogue between science and religion; the conflict between our human desire for permanence and the impermanence of nature; the possibility that our universe is simply an accident; the manner in which modern technology has separated us from direct experience of the world; and our resistance to the view that our bodies and minds can be explained by scientific logic and laws. And behind all of these considerations is the suggestion—at once haunting and exhilarating—that what we see and understand of the world is only a tiny piece of the extraordinary, perhaps unfathomable whole.

     Never before have the wonders of our solar system been so immediately accessible to readers of all ages. Award-winning writer and broadcaster Marcus Chown combines science and history to visually and narratively explore our neighboring planets, dwarf planets, moons and asteroids, as well as all of the historical figures who aided in their discoveries. From the explosive surface of the sun to the frosty blue dunes on Mars; from the gargantuan rings of Saturn to the volcanoes of Io; from geological maps of bedrock on the Moon, to a simulation of what the Oort Cloud might look like, Solar System offers a window seat from which to view the beauty and magnificence of space.

    This authoritative yet accessible study is the ultimate astronomy lesson. Combining fascinating and often alarming scenarios that seem plucked from science fiction with the latest research and opinions, Plait illustrates why outer space is not as remote as most people think. Each chapter explores a different phenomenon, explaining it in easy-to-understand terms, and considering how life on earth and the planet itself would be affected should the event come to pass. Rather than sensationalizing the information, Plait analyzes the probability of these catastrophes occurring in our lifetimes and what we can do to stop them. With its entertaining tone and enlightening explanation of unfathomable concepts, Death from the Skies! will appeal to science buffs and beginners alike.

    Before the decade is out, telltale signs that they harbor life may be found. If they are, the ramifications for all areas of human thought and endeavor--from religion and philosophy to art and biology--will be breathtaking. In Strange New Worlds, renowned astronomer Ray Jayawardhana brings news from the front lines of the epic quest to find planets--and alien life--beyond our solar system.Only in the past fifteen years, after millennia of speculation, have astronomers begun to discover planets around other stars--hundreds in fact. But the hunt to find a true Earth-like world goes on. In this book, Jayawardhana vividly recounts the stories of the scientists and the remarkable breakthroughs that have ushered in this extraordinary age of exploration. He describes the latest findings--including his own--that are challenging our view of the cosmos and casting new light on the origins and evolution of planets and planetary systems. He reveals how technology is rapidly advancing to support direct observations of Jupiter-like gas giants and super-Earths--rocky planets with several times the mass of our own planet--and how astronomers use biomarkers to seek possible life on other worlds.Strange New Worlds provides an insider's look at the cutting-edge science of today's planet hunters, our prospects for discovering alien life, and the debates and controversies at the forefront of extrasolar-planet research.

    Augustine equate nothingness with the Devil? What tortuous means did 17th-century scientists employ in their attempts to create a vacuum? And why do contemporary quantum physicists believe that the void is actually seething with subatomic activity? You’ll find the answers in this dizzyingly erudite and elegantly explained book by the English cosmologist John D. Barrow.Ranging through mathematics, theology, philosophy, literature, particle physics, and cosmology, The Book of Nothing explores the enduring hold that vacuity has exercised on the human imagination. Combining high-wire speculation with a wealth of reference that takes in Freddy Mercury and Shakespeare alongside Isaac Newton, Albert Einstein, and Stephen Hawking, the result is a fascinating excursion to the vanishing point of our knowledge.
