KM3NeT: Searching the Depths of the Sea for Elusive Neutrinos

The sun alone produces more than 64 billion neutrinos per second and per cm² that pass right through the Earth. These elementary particles of matter are everywhere, yet they remain almost entirely elusive.

The key word is almost… : The European infrastructure KM3NeT, currently being installed in the depths of the Mediterranean Sea, has been designed to detect the extremely faint light generated by neutrino interactions in the water. Researcher Richard Dallier from IMT Atlantique offers insight on the major scientific and technical challenge of searching for neutrinos.
