Italy is proposing a disused mineral mine in a distant nook of Sardinia to home one of the world’s most superior telescopes, hoping that the unusual stillness of the spot will clinch European Union approval and funds.
The Sos Enathos lead and zinc mine, extending 300 metres underground under lush vegetation, has been picked by the Rome authorities as its candidate to host the so-called Einstein Telescope (ET).
The breakthrough EU-financed mission goals to discover deep house via the examine of gravitational waves, and it could solely work with when floor vibrations are minimal.

“It will allow us … to see events very close to when the Big Bang happened” round 14 billion years in the past, 2021 Physics Nobel Prize winner Giorgio Parisi advised Reuters.
Parisi and different scientists say the mine is right due to the world’s low seismic exercise and the absence of settlements close by, however Italy faces a rival bid from a website in Meuse-Rhine, a area divided among the many Netherlands, Germany and Belgium.
The tender will likely be formally awarded no ahead of the top of subsequent yr.
Italy is betting that its 1.9-billion-euro ($2.09 billion)mission can convey much-needed funding to the island of Sardinia, one of the nation’s poorest areas.
The authorities has already invested 50 million euros of EU post-pandemic restoration funds in its bid, together with a feasibility examine.
Gravitational waves, the ripples in house and time predicted by Albert Einstein, are attributable to the collision of celestial entities like black holes.

The telescope is predicted to seize the waves and observe a quantity of the universe a lot bigger than is seen by the instruments at the moment used, often called interferometers.
A mine of alternatives
The Italian mission’s design envisages a triangle-shaped underground facility with 10-km-long arms.
Mirrors on the finish of every tunnel will replicate laser beams whose lengths are affected by the passage of gravitational waves. These minimal variations in size will likely be analysed by the ET.
Sos Enathos, close to the distant city of Lula in jap Sardinia, was a mining website for at the least 2,000 years earlier than being shut down in 1997.
Local authorities now see the telescope as a possibility to convey new life to an space hit by poor infrastructure, a declining birth-rate and depopulation.
“The mine has become the alternative to the mine,” Mario Calia, the 63-year-old mayor of Lula, advised Reuters.
Calia, himself a former miner, stated the mission would depart Lula’s unspoiled pure panorama untouched whereas bringing in funding. (Reporting by Federico Maccioni, modifying by Gavin Jones and Nick Macfie)
