Endless Universe: Beyond the Big Bang.ENDLESS UNIVERSE: Beyond the Big Bang big bang Model of the origin of the universe, which holds that it emerged from a state of extremely high temperature and density in an explosive expansion 10 billion–15 billion years ago. PAUL J. STEINHARDT AND NElL TUROK The Big Bang theory big bang theory n. A cosmological theory holding that the universe originated approximately 20 billion years ago from the violent explosion of a very small agglomeration of matter of extremely high density and temperature. Noun 1. posits that the universe sprang into being in a violent explosion more than 14 billion years ago. In recent decades, the theory has been revised on the basis of information that astronomers have gleaned from their ongoing observations of the skies as well as of new findings relating to relating to relate prep → concernant relating to relate prep → bezüglich +gen, mit Bezug auf +acc the apparent acceleration of the universe's expansion. In this book, leading cosmologists Steinhardt and Turok propose a provocative alternative theory to the Big Bang. They suggest that time and space didn't begin with a single, cataclysmic cat·a·clysm n. 1. A violent upheaval that causes great destruction or brings about a fundamental change. 2. A violent and sudden change in the earth's crust. 3. A devastating flood. explosion. On the contrary, the Big Bang was simply one event in a cycle of creation; it occurred as the result of a collision of this universe with a parallel one. They suggest that their theory addresses some of the flaws in the inflationary model of the universe and explain how theorists are using particle physics particle physics or high-energy physics Study of the fundamental subatomic particles, including both matter (and antimatter) and the carrier particles of the fundamental interactions as described by quantum field theory. and string theory to model the new, cyclic model of the universe's origins. The authors outline each theory and provide evidence to support what it proposes about the universe. Doubleday, 2007, 284 p., b&w illus., hardcover, $24.95. |
