Humanity's ongoing quest to unlock the secrets of dark matter and dark energy

Heart of Darkness describes the incredible saga of humankind's quest to unravel the deepest secrets of the universe. Over the past forty years, scientists have learned that two little-understood components—dark matter and dark energy—comprise most of the known cosmos, explain the growth of all cosmic structure, and hold the key to the universe's fate. The story of how evidence for the so-called "Lambda-Cold Dark Matter" model of cosmology has been gathered by generations of scientists throughout the world is told here by one of the pioneers of the field, Jeremiah Ostriker, and his coauthor Simon Mitton.

From humankind's early attempts to comprehend Earth's place in the solar system, to astronomers' exploration of the Milky Way galaxy and the realm of the nebulae beyond, to the detection of the primordial fluctuations of energy from which all subsequent structure developed, this book explains the physics and the history of how the current model of our universe arose and has passed every test hurled at it by the skeptics. Throughout this rich story, an essential theme is emphasized: how three aspects of rational inquiry—the application of direct measurement and observation, the introduction of mathematical modeling, and the requirement that hypotheses should be testable and verifiable—guide scientific progress and underpin our modern cosmological paradigm.

This monumental puzzle is far from complete, however, as scientists confront the mysteries of the ultimate causes of cosmic structure formation and the real nature and origin of dark matter and dark energy.

"In this stimulating study, the Princeton astrophysics professor and the University of Cambridge scholar offer a compelling insider's take on how astronomers have worked to reveal the mystery that is our universe. . . . Ostriker and Mitton's knowledge is vast, and while they acknowledge that our understanding of the universe is far from complete, this thought-provoking presentation is as accessible as it is exciting." - Publishers Weekly

"In this sweeping chronicle of cosmology, astrophysicist Jeremiah Ostriker and science historian Simon Mitton seamlessly blend historical narrative with lucid scientific explication, from the deeps of classical time to the data-fuelled hyperdrive of the past 50 years." - Nature

"A lucid history of cosmology. . . . With infectious enthusiasm, diagrams and even a little high school math, the authors deliver the available answers along with the increasing confusion. A fine introduction to cosmology but rich enough to inform readers familiar with introductions." - Kirkus Reviews

"[Heart of Darkness] traces the implications of modern cosmology and more. The path is a fascinating history from the first debates over cosmic redshift and the Hubble constant through the discovery of the cosmic microwave background by Penzias and Wilson in the 1960s right up to the big questions being raised today." - Astro Guyz

"Here is a new and welcome perspective on modern cosmology that any reader can easily grasp and appreciate. Excellent archival photos and a very useful appendix that clearly and simply explains some of the essential mathematical concepts add to the pleasure of reading this book. Written with authority and flair, this is one of the very best books on the topic. Recommended reading for any science buff." - Choice
