A bit of Lula in Bologna, in one of the most important Italian cities they talk about Einstein Telescope. Today the exhibition "Einstein Telescope: A look at the deep universe" ended at Palazzo d'Accursio, one of the many events aimed at spreading the importance of the ambitious project. From May 26 to 30, for example, the international ET community gathered in Bologna for its 15th annual Symposium, with over 300 researchers from all over the world.

The event, co-organized by the Department of Physics and Astronomy "Augusto Righi" of the University of Bologna, by INFN, INAF and INGV, represented an important opportunity to discuss the developments of the project, which aims to become the most advanced gravitational wave observatory in the world. Among presentations, thematic and plenary sessions dedicated to the scientific, economic-social and management aspects of the project, ongoing studies on the geological characterization of the Sos Enattos site in Lula and updates on the theme of the experiment configuration, initiatives for the public were also held, completely free of charge with the support of the European Gravitational Observatory.

From May 26th until today, the exhibition has been a huge piece for the people of Bologna and the visitors who, through the exhibition panels full of texts and images, have traveled between the past and the future, from Einstein's general relativity to gravitational waves and Sos Enattos, where we focused in particular. A few days after the inauguration of the exhibition, on May 29th, the conference show "The Universe underground. Einstein Telescope Sardinia" between science, art and territory was held at the nearby Cinema Modernissimo «to tell one of the most fascinating challenges of contemporary physics», wrote the organizers.

The event was held with Patrizio Roversi and the scientist Marica Branchesi, the physicist and EGO director Massimo Carpinelli, the internationally renowned Sardinian violinist Anna Tifu, and the illustrator, artist and scientist Angelo Adamo. Also on the 29th, and then on the 30th, in Piazza Galvani, the mobile laboratory "Big Bang Machine" was held, which guides the public on a journey to discover black holes, star fusions and instants of the cosmos. "In parallel to the scientific program - says the president of the Bologna City Council Maria Caterina Manca - several initiatives open to the public were organized to involve citizens and promote scientific culture. The exhibition in the Maniga Lunga of Palazzo d'Accursio offered a complete exhibition path, up to the future prospects of the observation of gravitational waves. All these initiatives had the aim of bringing the general public closer to the frontiers of physics and raising awareness of the importance of scientific research in the field of astrophysics and gravitational waves. The request to organize the exhibition here, at Palazzo d'Accursio, aroused great interest and joy that we welcomed with enthusiasm."
