{"product_id":"9781785783203","title":"Gravitational Waves: How Einstein's spacetime ripples reveal the secrets of the universe","description":"\u003cp\u003eOn 14 September 2015, after 50 years of searching, gravitational waves were detected for the first time and astronomy changed for ever.\u003c\/p\u003e\u003cp\u003eUntil then, investigation of the universe had depended on electromagnetic radiation: visible light, radio, X-rays and the rest. But gravitational waves- ripples in the fabric of space and time- are unrelenting, passing through barriers that stop light dead.\u003c\/p\u003e\u003cp\u003eAt the two 2.5 mile long LIGO observatories in the US, scientists developed incredibly sensitive detectors, capable of spotting a movement 100 times smaller than the nucleus of an atom. In 2015 they spotted the ripples produced by two black holes spiralling into each other, setting spacetime quivering.\u003c\/p\u003e\u003cp\u003eThis was the first time black holes had ever been directly detected- and it promises far more for the future of astronomy. Brian Clegg presents a compelling story of human technical endeavour and a new, powerful path to understand the workings of the universe.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e","brand":"Icon Books, Ltd.
