After forty years of controversy, the theorists finally reached a consensus: gravitational waves exist, would it be possible to develop instruments sensitive enough to detect these waves produced by tremendous cosmic collisions in the fabric of spacetime? The answer is affirmative&#8221;, Barish explained.<\/p>\n<p>On 14 September, 2015, the two interferometers of the Laser Interferometer Gravitational-Wave Observatory (LIGO), run by a Nobel Prize winner and honorary academician of the RAED, captured for the first time gravitational waves that came from the collision of two black holes. And in August of 2017, others generated by the fusion of two neutron stars. These detections opened a new window for the study of the universe.<\/p>\n<p>Dr Barish received the 2017 Princess of Asturias award for his work on gravitational waves with <strong>Kip Thorne<\/strong> and <strong>Rainer Weiss<\/strong> and, that same year, the Nobel prize in Physics (also with Weiss and Thorne), in both cases &#8220;for their decisive contribution to the LIGO detector and the observation of gravitational waves&#8221;.<\/p>\n<p>&nbsp;<\/p>\n<div class=\"atribucion\">Photograph of Barry Barish: By Bengt Nyman de Vaxholm, Sweden (Barry C.
