Dark matter is a type of matter hypothesized in astronomy and cosmology to account for a large part of the mass that appears to be missing from the universe. Dark matter cannot be seen directly with telescopes; evidently it neither emits nor absorbs light or other electromagnetic radiation at any significant level. Instead, the existence and properties of dark matter are inferred from its gravitational effects on visible matter, radiation, and the large-scale structure of the universe. According to the Planck mission team, and based on the standard model of cosmology, the total mass–energy of the known universe contains 4.9% ordinary matter, 26.8% dark matter and 68.3% dark energy. Thus, dark matter is estimated to constitute 84.5% of the total matter in the universe and 26.8% of the total content of the universe.. Cosmology.

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? as Philosophy not Science.
