Paperback. Etat : Fair. We are made of stardust-and so is all life as we know it. All the chemical elements on earth except hydrogen-including the ones in our bodies-have been processed inside stars, scattered across the universe in great stellar explosions, and recycled to become new stars, planets, and parts of us. In this engrossing book, John and Mary Gribbin relate the developments in twentieth-century astronomy that have led to this shattering realization. They begin their account in the 1920s, when astronomers discovered that the oldest stars are chiefly composed of the primordial elements hydrogen and helium, produced in the birth of the universe in a Big Bang. They then describe the seminal work of the 1950s and 1960s, which unlocked the secret of how elements are "cooked" by nuclear fusion inside stars. The heart of the story is their discussion of supernovae, only recently understood as great stellar explosions in which the resulting ash is spread far and wide through the cosmos, forming new generations of stars, planets, and people. Focusing on the relationship between the universe and the Earth, the authors eloquently explain how the physical structure of the universe has produced conditions ideal for life. …

Paperback. Etat : Fair. The bestselling author of>In Search of Schr dinger's Cat>examines the science of dark matter and ultimate fate of the universe. Is the universe infinitely expanding? Or at some point in the future will it finally reach its limit--and contract upon itself in one catastrophic reversal of the Big Bang? The ultimate answer to this perplexing question rests on one factor: the omega point. In one of the most astonishing developments of astronomy, scientists have recently discovered that more than 90 percent of the universe is missing. In>The Omega Point, acclaimed science writer and cosmologist John Gribbin investigates the perplexing mystery of this missing or dark matter. How much of it exists? What is it made of? And is its gravitational force enough to reach the omega point--the amount needed to cause the big crunch, as this last fatal cosmological squeeze has been nicknamed? From its first moments of creation, deep in the outermost regions of space, down to the microworld of quarks, bayrons, mesons, and other exotic forms of matter, Gribbin takes us on a fascinating journey along the arrow of time to discover the true nature of the universe we live in. One of the best science writers around.--Nature.…
