Astronomer Joseph Silk explores the Universe from its beginnings to its ultimate fate. He demonstrates how cosmologists study cosmic fossils and relics from the distant past to construct theories of the birth, evolution and future of the Universe. Stars, galaxies, dark matter and dark energy are described, as successive chapters detail the evolution of the Universe from a fraction of a microsecond after the Big Bang. Silk describes how physicists apply theories of subatomic particles to recreate the first moments of the Big Bang, and how astronomers chart the vast depths of space to glimpse how the most distant galaxies formed. He gives an account of the search for dark matter and the dark energy that will determine the ultimate fate of the Universe. Joseph Silk is the Savilian Professor of Astronomy and Head of the Astrophysics Department at the University of Oxford. He was previously Professor of Astronomy at the University of California, Berkeley. He holds a BA in Mathematics from Clare College, Cambridge, and a PhD in Astronomy from Harvard University. Silk is the author, or co-author, of many books, including The Left Hand of Creation (Basic Books, 1994) and A Short History of the Universe (WH Freeman, 1997). He is a Fellow of the Royal Society, the American Physical Society, and the American Association for the Advancement of Science.
