Gravitational Waves: How Einstein's Spacetime Ripples Reveal

On 14 September 2015, after 50 years of searching, gravitational waves were detected for the first time and astronomy changed for ever.

This book introduces gravitational waves and discusses some of their applications in five dimensions, this is all done in classical gravity. It also explains gravitational waves in quantum gravity (in which the universe is considered to be not continuous) and implications for trying to understand and explore dark energy and an expanding accelerated universe.

This book provides a concise introduction to the physics of gravitational waves. It is aimed at graduate-level students and PhD scholars.

This book is to help post-graduate students to get into gravitational wave astronomy. We assume the knowledge of General Relativity theory, though we will concentrate on the physics and often omit mathematically strict derivations. We provide references to already existing literature where possible, this helps us to see a broad picture, skipping the details. The uniqueness of this book is in that it covers three frequency bands and three major world-wide efforts to detect gravitational waves.
