They are the first time travelers--guinea pigs in an experiment that cannot fail. From a future ravaged by plague, they must travel thousands of years into the past to the dawn of civilization. Among tribes of primitive hunters, they will trace a fatal chain of events--and alter history to save humanity from itself.

From the very first moments of the universe to the birth of the first star, our solar system, and our planet: a physicist traces the known and the unknown. Since the beginning of the twentieth century, the horizon of our knowledge about the universe has expanded to encompass the infinitesimally small—and the infinitely vast. In First Dawn, physicist Roberto Battiston takes readers on a journey through space and time, to the boundaries of our knowledge and beyond. From the violence of the Big Bang and the birth of the first star, hundreds of millions of years later, to the emergence of our solar system, the dawn of life on Earth, and the possibility of life on other planets, Battiston maps what we know about the universe and how we came to know it—cautioning us, however, that what we know is a minuscule fraction of what there is to know. Battiston outlines discoveries by some of the greatest theoretical physicists of the twentieth century, including Einstein, Bohr, Schrödinger, Heisenberg, Fermi, and Hubble; discusses the mysteries of dark energy and dark matter; and considers what it means for the universe to have emerged out of nothing. The ignition of the first star illuminated a universe that had been expanding, unobserved and unobservable, in the dark. Drawing on his own research, Battiston discusses the birth of the Sun, the formation of planets, the origins of life, interstellar migrations, extrasolar planets, black holes, gravitational waves, and much more. But, he warns, for some questions—the dimensions of the universe, for example, or the existence of other universes—we are destined to remain in the realm of speculation.

Astronomers have successfully observed a great deal of the Universe's history, from recording the afterglow of the Big Bang to imaging thousands of galaxies, and even to visualising an actual black hole. There's a lot for astronomers to be smug about. But when it comes to understanding how the Universe began and grew up we are literally in the dark ages. In effect, we are missing the first one billion years from the timeline of the Universe. This brief but far-reaching period in the Universe's history, known to astrophysicists as the 'Epoch of Reionisation', represents the start of the cosmos as we experience it today. The time when the very first stars burst into life, when darkness gave way to light. After hundreds of millions of years of dark, uneventful expansion, one by the one these stars suddenly came into being. This was the point at which the chaos of the Big Bang first began to yield to the order of galaxies, black holes and stars, kick-starting the pathway to planets, to comets, to moons, and to life itself. Incorporating the very latest research into this branch of astrophysics, this book sheds light on this time of darkness, telling the story of these first stars, hundreds of times the size of the Sun and a million times brighter, lonely giants that lived fast and died young in powerful explosions that seeded the Universe with the heavy elements that we are made of. Emma Chapman tells us how these stars formed, why they were so unusual, and what they can teach us about the Universe today. She also offers a first-hand look at the immense telescopes about to come on line to peer into the past, searching for the echoes and footprints of these stars, to take this period in the Universe's history from the realm of theoretical physics towards the wonder of observational astronomy.

The paleoanthropologist who discovered "Lucy" teamed up with the artist Kevin O'Farrell to re-create, as closely as the facts allow, what life was like for the world's first family more than 3 million years ago.

Have you ever wondered how we really know what year it is? Part detective story, part conspiracy theory, part scientific history, The Lost Millennium explores the astonishing possibility that our calendar is out by a thousand years. A chance conversation at a conference in Mexico started mathematician Florin Diacu on an amazing journey to make sense of one of the strangest — and if true, most revolutionary — theories you’ll ever encounter. To understand how scientists could be sceptical about what year it is, Florin Diacu explores the fascinating history of chronology — from Egyptian horoscopes to the work of Isaac Newton, with cameos by Voltaire and Edmund Halley — making the startling discovery that our calendar is far from ironclad. It all depends, rather, on the dating of ancient events — about which there is real controversy. At once accessible and profound, The Lost Millennium examines the arguments of present-day chronological revisionists such as the Russian scholar Anatoli Fomenko, who claims that our system of dating is horribly askew. Fomenko cites evidence from ancient astronomy, linguistics and cartography, and a crucial manuscript by Ptolemy, staking his scientific prestige on a theory so controversial that it will change the way you think about time, history and the calendar on your wall. The field has also inspired its share of now-discredited cranks, such as Immanuel Velikovsky, a media celebrity of the 1950s. His notorious book Worlds in Collision argued that biblical events are incorrectly dated. Beautifully written and peopled with fascinating characters from past and present, The Lost Millennium is essential reading for anyone who believes they’re living in the year 2005.
