Beschreibung
In the first chapters the author describes how our knowledge of the position of Earth in space and time has developed, thanks to the work of many generations of astronomers and physicists. He discusses how our position in the Galaxy was discovered, and how in 1929, Hubble uncovered the fact that the Universe is expanding, leading to the picture of the Big Bang. He then explains how astronomers have found that the laws of physics that were discovered here on Earth and in the Solar System (the laws of mechanics, gravity, atomic physics, electromagnetism, etc.) are valid throughout the Universe. This is illustrated by the fact that all matter in the Universe consists of atoms of the same chemical elements that we know on Earth. This unity is all the more surprising when one realizes that in the original Big Bang theory, different parts of the Universe could never have communicated with each other. It then is a mystery how they could have shared the same physical laws. This problem was solved by the introduction of the idea of inflation, a phase of extremely rapid expansion of the Universe during the first fraction of a second following the Big Bang. The author explains how the unity of the Universe finds its origin in the Big Bang prior to inflation. The book addresses the many fundamental questions about the Universe and its contents from the perspective of the Big Bang: the formation of structure in the Universe, the questions of the mysterious dark matter and dark energy, the possibilities of other Universes (the Multiverse) and of the existence of intelligent life elsewhere in the Universe.
Discusses the ways in which the laws of physics, which are valid throughout the Universe, find their origin in the Big Bang Gives new historical details of 1917 predictions and the subsequent discovery that the Universe is expanding Emphasizes the close interconnection between the Universe and the evolution of life on Earth throughout the book Presents how Earth is placed in space and time in a novel way

“One cannot wish for a better guide for a tour through the universe than this comprehensive account of modern astrophysics and cosmology by one of its masters. This engaging and highly informative book weaves cutting-edge research, basic scientific principles and historical developments into a vast fabric that dazzles the reader.” (Robbert Dijkgraaf, Director, Institute for Advanced Study, Princeton, New Jersey, Leon Levy Professor of Theoretical Physics)
“This clear, conversational account of the universe has it all. One of our leading astrophysicists paints a glowing picture of our extra-ordinary world – from planets to the cosmos –and engagingly recounts the tale of how we have decoded the signals arriving at our telescopes from outer space with the aid of laboratories, computers and our native wit.” (Jeremiah P. Ostriker, Professor of Theoretical Astrophysics, Columbia University, New York)
“Edward van den Heuvel is one of the leading astrophysicists of his generation. He covers everything -- from planets to the big bang -- with authority and balance. He sets the latest discoveries in a historical context and explains the physics that underlies them. Anyone wanting a clear and accessible account of all we've learnt about the cosmos should read this clearly written and beautifully produced book.” (Martin Rees, Professor of Cosmology and Astrophysics, University of Cambridge, UK, Astronomer Royal)“I read this exciting book with great pleasure. Ed van den Heuvel is one of the world’s most recognized scientists and a great expert in the field of the theory of evolution of binary stars and high energy astrophysics. However, I have never seen him from the perspective as writer of a popular book so broad in topics from cosmology to the origin of intelligent life (a topic which is becoming so interesting now that astronomers have discovered dozens of habitable planets in distant stellar systems). However, he succeeded. It is very impressive how well the author uses the key laws of physics to explain the evolution and properties of our Universe, how gently he demonstrates the role of theoretical prediction in the development of modern astronomy and cosmology, in addition to the great progress in the development of new extremely sensitive astronomical spacecrafts, telescopes and detectors.” (Rashid Sunyaev, Scientific Director, Max Planck Institute for Astrophysics, Garching, Germany)
