A half century ago, a shocking Washington Post headline claimed that the world began in five cataclysmic minutes rather than having existed for all time; a skeptical scientist dubbed the maverick theory the Big Bang. In this amazingly comprehensible history of the universe, Simon Singh decodes the mystery behind the Big Bang theory, lading us through the development of one of the most extraordinary, important, and awe-inspiring theories in science.

Everyone knows that there are things no one can see, for example, the air you're breathing or a black hole, to be more exotic. But not everyone knows that what we can see makes up only 5 percent of the Universe. The rest is totally invisible to us.

The invisible stuff comes in two varieties--dark matter and dark energy. One holds the Universe together while the other tears it apart. What these forces really are has been a mystery for as long as anyone has suspected they were there, but the latest discoveries of experimental physics have brought us closer to that knowledge. Particle...

Astrophysicist George Smoot spent decades pursuing the origin of the cosmos, "the holy grail of science," a relentless hunt that led him from the rain forests of Brazil to the frozen wastes of Antarctica. In his search he struggled against time, the elements, and the forces of ignorance and bureaucratic insanity. Finally, after years of research, Smoot and his dedicated team of Berkeley researchers succeeded in proving the unprovable--uncovering, inarguably and for all time, the secrets of the creation of the universe. Wrinkles in Time describes this startling discovery that would...

Modern Cosmology begins with an introduction to the smooth, homogeneous universe described by a Friedman-Robertson-Walker metric, including careful treatments of dark energy, big bang nucleosynthesis, recombination, and dark matter. From this starting point, the reader is introduced to perturbations about an FRW universe: their evolution with the Einstein-Boltzmann equations, their generation by primordial inflation, and their observational consequences. These consequences include the anisotropy spectrum of the cosmic microwave background (CMB) featuring acoustic peaks and...

Previously the domain of philosophers and linguists, information theory has now moved beyond the province of code breakers to become the crucial science of our time. In Decoding the Universe, Charles Seife draws on his gift for making cutting-edge science accessible to explain how this new tool is deciphering everything from the purpose of our DNA to the parallel universes of our Byzantine cosmos. The result is an exhilarating adventure that deftly combines...

Everyone knows that the universe is extremely old and extremely large. But how did scientists determine just how old and how large? How do astronomers know that there are upwards of 100 billion galaxies in the universe if the nearest one is over 40,000 light-years away? How do we know what the stars are made of? The answer is that our current knowledge of the universe has arisen from the work and ideas of scientists and philosophers over hundreds of years. While it's only been during the last several decades that scientists have had the technology and theories to really understand how the...

What should the average person know about science? Because science is so central to life in the 21st century, science educators and other leaders of the scientific community believe that it is essential that everyone understand the basic concepts of the most vital and far-reaching disciplines. "Cosmology 101" does exactly that. This accessible volume provides readers - whether students new to the field or just interested members of the lay public - with the essential ideas of evolution using a minimum of jargon and mathematics. Concepts are introduced in a progressive order so that more...
