Heart of Darkness : Unraveling the Mysteries of the Invisible Universe

Heart of Darkness describes the incredible saga of humankind’s quest to unravel the deepest secrets of the universe. Over the past thirty 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.

Journey of the Universe

Today we know what no previous generation knew: the history of the universe and of the unfolding of life on Earth. Through the astonishing combined achievements of natural scientists worldwide, we now have a detailed account of how galaxies and stars, planets and living organisms, human beings and human consciousness came to be. And yet… we thirst for answers to questions that have haunted humanity from the very beginning.

Did Time Begin? Will Time End? Maybe The Big Bang Never Occurred

Although everyone is familiar with the concept of time in everyday life and has probably given thought to the question of how time began, recent scientific developments in this field have not been accessible in a simple understandable form. This book is important as it presents to readers current ideas about the role of time in theoretical cosmology.Recent observational discoveries, especially that the expansion rate of the universe is accelerating, have revolutionized the understanding of the energy content of the universe. This development leads to new possibilities for the beginning and end of cosmological time.
