WHISPER OF THE COSMOS HEARD. THE DISCOVERY OF GRAVITATIONAL WAVES NARRATED BY ONE OF THE PROTAGONISTS
Interview with Fulvio Ricci, spokesperson of the VIRGO international Collaboration
It is the scientific news of 2016. The discovery, awaited for a century, of the gravitational waves predicted by Albert Einstein in his Theory of General Relativity .
A revolutionary milestone, which changes our outlook on the universe.
The important result was achieved, thanks to the data of the twin detectors LIGO (Laser Interferometer Gravitational-wave Observatory), by the LIGO Scientific Collaboration (which includes the GEO600 Collaboration, the Australian Consortium for Interferometric Gravitational Astronomy) and VIRGO, part of the European Gravitational Observatory (EGO), founded by the National Institute for Nuclear Physics (INFN) and the French Centre National de la Recherche Scientifique (CNRS).
We asked one of the protagonists of this scientific enterprise, Fulvio Ricci, spokesperson of the VIRGO Collaboration, to tell us how this result was achieved, and how our understanding of the cosmos will change from now on.
The first direct gravitational wave signal was captured on 14 September 2015 after a century-long wait. Can you describe your feelings on that day?
I remember having received the first news of the signal via an email from Marco Drago, a young researcher trained in Italy by INFN and since one year in Germany, at the Max Planck Institute in Hannover. My first reaction was one of scepticism and incredulity. ...
