Thisisthesecondeditionofabookonthephenomenological foundations ofmodern cosmology. The ?rst edition was surprisingly well timed. In the preceding 3 years, advances in astronomy had laid the foundations of the dark-energy/dark-matter c- mological model. In 1998, observations of type Ia supernova by the Supernova C- mology Project and High Z team suggested that the expansion of the universe is accelerating. In 2000, Boomerang and Maxima observed clearly the ?rst acoustic peak in the anisotropy spectrum of the cosmic microwave background. The position of the peak strongly suggested that the...
