For centuries, it was assumed that our universe was static. In the late 1920s, astronomers defeated this assumption with a startling new discovery. From Earth, the light of distant galaxies appeared to be red, meaning that those galaxies were receding from us. This led to the revolutionary realization that the universe is expanding. The Red Limit is the tale of this discovery, its ramifications, and the passionately competitive astronomers who charted the past, present, and future of the cosmos.

David Harland describes the historical development of particle physics, and explains, in a non-mathematical way, how particle physics has influenced the structure of the Universe from the very beginning of time. He demonstrates the close links between discoveries in particle physics and in cosmology up to the present. He describes how our understanding of the Universe has developed from the discovery that the Universe is expanding, to the idea that all matter originated in a hot, Big Bang, then explains the many subtle improvements to the basic theory that have been necessary to understand how the very smallest particles and earliest structures (the 'microscale') in the Universe evolved to produce the Universe as it is now (the 'macroscale'). The author also describes how scientists are attempting to develop a 'Theory of Everything' that would explain how an instant after the Big Bang a single primordial force was transformed into the four forces of nature that we observe today, which hitherto were believed to be 'fundamental'.

Are we living in the "golden age" of cosmology? Are we close to understanding the nature of the unknown ingredients of the currently most accepted cosmological model and the physics of the early Universe? Or are we instead approaching a paradigm shift? What is dark matter and does it exist? How is it distributed around galaxies and clusters? Is the scientific community open to alternative ideas that may prompt a new scientific revolution - as the Copernican revolution did in Galileo's time? Do other types of supernovae exist that can be of interest for cosmology? Why have quasars never been effectively used as standard candles? Can you tell us about the scientific adventure of COBE? How does the extraction of the Cosmic Microwave Background anisotropy depend on the subtraction of the various astrophysical foregrounds? These, among many others, are the astrophysical, philosophical and sociological questions surrounding modern cosmology and the scientific community that Mauro D'Onofrio and Carlo Burigana pose to some of the most prominent cosmologists of our time. Triggered by these questions and in the spirit of Galileo's book "Dialogue Concerning the Two Chief World Systems" the roughly 40 interview partners reply in the form of essays, with a critical frankness not normally found in reviews, monographs or textbooks.

The infinite! No other question has ever moved so profoundly the spirit of man; no other idea has so fruitfully stimulated his intellect; yet no other concept stands in greater need of clarification than that of the infinite. . . - David Hilbert (1862-1943) Infinity is a fathomless gulf, There is a story attributed to David Hilbert, the preeminent mathe into which all things matician whose quotation appears above. A man walked into a vanish. hotel late one night and asked for a room. "Sorry, we don't have o Marcus Aurelius (121- 180), Roman Emperor any more vacancies," replied the owner, "but let's see, perhaps and philosopher I can find you a room after alL" Leaving his desk, the owner reluctantly awakened his guests and asked them to change their rooms: the occupant of room #1 would move to room #2, the occupant of room #2 would move to room #3, and so on until each occupant had moved one room over. To the utter astonish ment of our latecomer, room #1 suddenly became vacated, and he happily moved in and settled down for the night. But a numbing thought kept him from sleep: How could it be that by merely moving the occupants from one room to another, the first room had become vacated? (Remember, all of the rooms were occupied when he arrived.

In 1923 Edwin Hubble confirmed the existence of other galaxies. By the end of the decade, he proved that the universe is expanding, thus laying the very cornerstone of the big bang theory. A revealing portrait of a scientific genius at work, this book also offers an incisive narrative of the history of astronomy, and an evocation of what we see when gazing at the stars. "Highly entertaining. . . . Hubble may have been the most important astronomer since Galileo. Perhaps since Copernicus."—Dick Teresi, New York Times Book Review "Hubble's own story has not been adequately told until now. . . . A riveting portrait of a great scientist and a haunted man, and the best look we are likely to have of the real Hubble."—Dennis Overby, Los Angeles Times Book Review "Displays remarkable strength in its steadfast balance and scrupulous honesty. The greatness of the discoveries is set off against the contrasting pettiness of the man."—Hans Christian von Baeyer, Boston Sunday Globe "Fascinating. . . . This is one of the most impressive scientific biographies of recent years."—Kirkus Review, starred review — "Notable Books for the Year 1995" selection, New York Times Book Review —"Best Books of 1995" selection, Library Journal —Selected as one of the five best science books in 1995 by Carl Sagen, Washington Post

For over three millennia, most people could understand the universe only in terms of myth, religion, and philosophy. Between 1920 and 1970, cosmology transformed into a branch of physics. With this remarkably rapid change came a theory that would finally lend empirical support to many long-held beliefs about the origins and development of the entire universe: the theory of the big bang. In this book, Helge Kragh presents the development of scientific cosmology for the first time as a historical event, one that embroiled many famous scientists in a controversy over the very notion of an evolving universe with a beginning in time. In rich detail he examines how the big-bang theory drew inspiration from and eventually triumphed over rival views, mainly the steady-state theory and its concept of a stationary universe of infinite age. In the 1920s, Alexander Friedmann and Georges Lema�tre showed that Einstein's general relativity equations possessed solutions for a universe expanding in time. Kragh follows the story from here, showing how the big-bang theory evolved, from Edwin Hubble's observation that most galaxies are receding from us, to the discovery of the cosmic microwave background radiation. Sir Fred Hoyle proposed instead the steady-state theory, a model of dynamic equilibrium involving the continuous creation of matter throughout the universe. Although today it is generally accepted that the universe started some ten billion years ago in a big bang, many readers may not fully realize that this standard view owed much of its formation to the steady-state theory. By exploring the similarities and tensions between the theories, Kragh provides the reader with indispensable background for understanding much of today's commentary about our universe.
