Gravitational Physics assesses the achievements of the field over the past decade in both theory and experiment, identifies the most promising opportunities for research in the next decade, and describes the resources necessary to realize those opportunities. A major theme running through the opportunities is the exploration of strong gravitational fields, such as those associated with black holes. The book, part of the ongoing decadal survey Physics in a New Era, examines topics such as gravitational waves and their detection, classical and quantum theory of strong gravitational fields, precision measurements, and astronomical observations relevant to the predictions of Einstein's theory of general relativity.Some of the key questions in quantum gravity are the following: ac How can the principles of general relativity and ... fuse together, providing deeper insights and perhaps complete answers to these fundamental questions about nature. ... Usual quantum mechanics is recovered in those epochs and situations in which the spacetime geometry is approximately classical. This conceptual advance resulted from a fruitful interchange of ideas between experts working on quantum gravity, anbsp;...
