The Cosmic Microwave Background: Historical and Philosophical Lessons [Hardcover]

Explanations of the cosmic microwave background prompt this unique case study of theory building in modern science.The untold story of how the cosmic microwave background radiation was interpreted following its discovery is a modern case study of theory building within the history and philosophy of science. It examines the epistemological factors at play between the emerging scientific orthodoxy of the Big Bang theory and its alternatives.The untold story of how the cosmic microwave background radiation was interpreted following its discovery is a modern case study of theory building within the history and philosophy of science. It examines the epistemological factors at play between the emerging scientific orthodoxy of the Big Bang theory and its alternatives.This volume tells the untold story of how observations of the cosmic microwave background radiation were interpreted in the decades following its serendipitous discovery, before the Hot Big Bang model became the accepted orthodoxy. The authors guide the reader through this history, including the many false trails and blind alleys that occurred along the way. Readers will discover how the Big Bang theory was shaped by alternative theories that exposed its weaknesses  including some that persist even today. By looking carefully at what it takes to reject an incorrect theory and the assumptions and processes at each stage, the authors examine the epistemological factors at play between an emerging scientific orthodoxy and since discarded alternatives. Their analysis of the cosmic microwave background provides a uniquely well-documented case study of theory building for a wide readership spanning cosmology, the history of physics and astronomy, and the philosophy of science more broadly.Introduction; Part I.
