{"product_id":"gravitational-waves","title":"Gravitational Waves","description":"On 14 September 2015, after 50 years of searching, gravitational waves were detected for the first time and astronomy changed for ever.\u003cbr data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003e Until 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.\u003cbr data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003e At 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.\u003cbr data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003e This 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":"Readers Paradise Book Shop Wexford","offers":[{"title":"Default Title","offer_id":42242742845611,"sku":"","price":5.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0538\/7105\/0923\/products\/1_df48faad-bf08-4288-9033-eed1b506e81b.jpg?v=1665832940","url":"https:\/\/readersparadise.pro\/products\/gravitational-waves","provider":"ReadersParadise","version":"1.0","type":"link"}
