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 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.\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","brand":"The Bookhouse Broughty Ferry","offers":[{"title":"Default Title","offer_id":40578884698247,"sku":"9781785783203","price":10.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0357\/3199\/6807\/files\/9781785783203_ce444fb2-00d7-4706-873c-412545d8ff80.jpg?v=1741631198","url":"https:\/\/thebookhousebroughtyferry.pro\/products\/9781785783203","provider":"The Bookhouse Broughty Ferry","version":"1.0","type":"link"}
