But gravitational waves - ripples in the fabric of space and time - are unrelenting, passing through barriers that stop light dead. \u003cp\u003e\u003c\/p\u003e \u003cp\u003e\u003c\/p\u003eAt the two 4-kilometre 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. \u003cp\u003e\u003c\/p\u003e \u003cp\u003e\u003c\/p\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.","brand":"Icon Books","offers":[{"title":"Paperback","offer_id":45084038398103,"sku":"9781785783203","price":455.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9781785783203.webp?v=1767636386","url":"https:\/\/atlanticbooks.com\/products\/gravitational-waves-how-einsteins-spacetime-ripples-reveal-the-secrets-of-the-universe-9781785783203","provider":"Atlantic Books","version":"1.0","type":"link"}
