Scientists have been trying to confirm the existence of gravitational waves for fifty years. Then, in September 2015, came a "very interesting eventż (as the cautious subject line in a physicist's email read) that proved to be the first detection of gravitational waves. In Gravity's Kiss, Harry Collinsżwho has been watching the science of gravitational wave detection for forty-three of those fifty years and has written three previous books about itżoffers a final, fascinating account, written in real time, of the unfolding of one of the most remarkable scientific discoveries ever made. Predicted by Einstein in his theory of general relativity, gravitational waves carry energy from the collision or explosion of stars. Dying binary stars, for example, rotate faster and faster around each other until they merge, emitting a burst of gravitational waves. It is only with the development of extraordinarily sensitive, highly sophisticate, detectors that physicists can now confirm Einstein's prediction. This is the story that Collins tells.
