Foundations of Quantum Cosmology (eBook, ePUB)

• Format: ePub

Produktbeschreibung

Quantum cosmology, an application of quantum physics to theories of the universe, has been studied for more than five decades. Initially proposed as a mathematical model to test possible quantum theories of gravity, the field is now expected to be in reach of experimental relevance thanks to a wealth of new data from observations of the cosmic microwave background, gravitational waves, or the accelerated expansion of the universe. This change of perspective requires not only new phenomenological methods, but also a careful look at the physical foundations of the theory, making sure that predictions of potentially observable effects are reliable.

This is the first book that aims to lay the foundations of quantum cosmology. It develops classical cosmology and quantum physics based on general principles without requiring detailed background knowledge in these fields. No previous exposure to general relativity is required, although it may be useful. Throughout the book, the discussion focuses on the physical meaning of space-time - classical or quantum - and on the important requirement of general covariance. Various classical models are derived from this condition and applied to basic questions in cosmology and the physics of black holes. The book's introduction of relevant ingredients from quantum physics makes it possible to derive fundamental features of quantum cosmology, to present the main approaches to quantum gravity, including string theory and causal dynamical triangulations, and to outline some of their cosmological implications. It is a perfect guide for researchers in quantum gravity and astrophysicists interested in fundamental aspects of cosmology.
