In the next few years Advanced Virgo, will achieve a sensitivity allowing, with a high probability, the direct detection of gravitational waves. This event will open the study of gravitational field propagation, which is described by the Einstein’s General Relativity, a theory based on the principle of local invariance with respect to arbitrary transformations of the coordinate systems. This invariance is extended to the description of the force fields as it happen for example in the case of the electroweak interactions, providing a conceptual basis for the unification of gravity with the other elementary forces. In Italy, Edoardo Amaldi sensed the importance of these studies and pushed for their start-up, recommending to follow the developments with consistency. He supported with prophetic insight (the gauge theories were not yet established) that these studies had to be carried out in parallel to those of particle physics and fundamental interactions. The boost given by Edoardo Amaldi, supported by INFN since 1980, produced as consequence that nowadays Italy hosts one of the three most sensitive gravitational wave detectors in the world. The Virgo perspective, in its advanced configuration, is to reveal directly the waves emitted in gravitational collapses that occurred in distant galaxies. These signals are produced by the coherent motion of large masses and, in a perspective which has some similarities with the deep inelastic scattering studies in particle physics, will permit to probe the properties of the gravitational interaction. These instruments will open a new window on the cosmos as it occurred with the discovery of the telescope at the Galileo’s epoch. The INFN meeting of April, 7 - 8 is an opportunity to clarify the scientific prospective of the Italian contribution to the advancement of the fundamental physics and in particular to the gravitational research in the world. To prepare this event, we plan to devote on March 4, a day to study and discuss the scientific perspectives of Advanced Virgo, its evolution and the path toward the Einstein Telescope, the third generation of gravitational wave detector, with the aim to involve the wide community of physicists studying the fundamentals interaction.
