A team of international scientists recorded the gravitational waves of two black holes colliding 1.3 billion light-years away. This discovery was announced simultaneously in France (CNRS), Italy (INFN) and the United States (NSF) on February 11, 2016.
In France, M. Thierry Mandon, French minister for higher education and research, emphasized that International collaboration has been especially crucial in this discovery .
75 French scientists from 6 CNRS (French National Center for Scientific Research) laboratories have been involved in the project, three of them, Matteo Barsuglia, Fabien Cavalier and Laurent Pinard, participated in the National Science Foundation (NSF) Press Conference in Washington, DC on February 11, 2016.

By detecting gravitational waves for the first time, the U.S. Gravitational-wave Observatory LIGO and teams from the French-Italian Gravitational-wave Observatory EGO-VIRGO were also first in observing a collision between two black holes, thus opening a new window to the Universe.
After a quest that lasted half a century, physicists—more precisely those working since 2007 as part of the international collaboration associating the LIGO and EGO-VIRGO observatories—have finally found the Holy Grail: the first detection of a gravitational wave; the latter having been generated by the collision of two black holes. Not only does this discovery further validate Einstein’s theory, it also brings astronomy into a new era by providing an entirely novel way to observe the most violent phenomena in the Universe.
The EGO-VIRGO observatory is currently beeing upgraded to improve its sensivity and will be able to work simultaneously with the two U.S. LIGO observatories in late 2016. This will hopefully enable the triangulation of Gravitational waves and create unprecedented opportunities for Science.
