دانلود کتاب Before the Big Bang: The Prehistory of Our Universe

According to a recent survey, the most popular question about science from the general public was: what came before the Big Bang? We all know on some level what the Big Bang is, but we don’t know how it became the accepted theory, or how we might know what came before. In Before the Big Bang, Brian Clegg (the critically acclaimed author of Upgrade Me and The God Effect) explores the history of this remarkable concept. From the earliest creation myths, through Hershel’s realization that the Milky Way was one of many galaxies, to on-going debates about Black Holes, this is an incredible look at the origins of the universe and the many theories that led to the acceptance of the Big Bang. But in classic scientist fashion Clegg challenges the notion of the “Big Bang” itself, and raises the deep philosophical question of why we might want to rethink the origin of the universe. This is popular science at its best, exploratory, controversial, and utterly engrossing.
