Cosmology and the Evolution of the Universe provides readers with an up-to-date survey of the current scientific understanding of how the universe has evolved in the almost 14 billion years since the Big Bang. Scientifically sound and written with the student in mind, it is an excellent first step for students researching the science of cosmology and a resource for all who wish to know more about the evolution of the universe.Cosmology and the Evolution of the Universe discusses all areas of what is known about the subject. Topics include: the large-scale structure of the universe the discovery and importance of cosmic microwave background radiation and the forces and particles involved in the evolution of the universe. The book even tackles that most provocative of questions: How will the universe end? By now, your child will already understand the big concepts on astronomy. Included in this astronomy book are the history and future of space exploration as well as the types of equipment needed for a safe space travel. In addition, your student will learn about the scientific evidence for the origin, as well as age, of the universe. Read this book today.
