Sardinia would be "an excellent site" to host the Einstein Telescope : these are the words of two Nobel Prize winners in Physics, Arthur McDonald and Takaaki Kajita , who expressed their support for the Italian candidacy during an event at Expo2025 Osaka organized by the National Institute for Nuclear Physics during the Sardinia Region Week.

Arthur McDonald and Takaaki Kajita, awarded the Nobel Prize in 2015 for their studies on the mass of neutrinos, had the opportunity in Osaka to talk about the scientific cooperation between Italy and Japan in the field of gravitational waves and also demonstrated their appreciation for the unique characteristics that distinguish the Sardinian site of Sos Enattos, a candidate from Italy to host the future gravitational wave detector.

"We realized that it would be a great site to install an underground gravitational wave interferometer," Kajita says, "because the seismic activity is very low and the amount of underground water is also minimal . I therefore believe that Sardinia is a really good candidate site for the Einstein Telescope."

Arthur McDonald, heavily involved in the ARIA project – the Sardinian plant for the distillation of Argon-40, a fundamental chemical element for the search for dark matter – reiterated, in a speech recorded for the occasion, the suitability of the Sardinian site , and offered his support for the Italian candidacy also in light of the great quality of its research.
