The KM3NeT consortium consists of about 200 scientists preparing the design, construction and operation of the largest and most precise neutrino telescope on Earth. This instrument will be built at the bottom of the Mediterranean Sea, and will look for particle tracks coming out of the Earth. Such tracks can be associated with high energy neutrinos that passed through the Earth.
The observation of high energy neutrino sources in the universe is expected to clarify the so far mysterious origin of cosmic rays and may enable us to unravel the nature of dark matter, a mysterious substance making up some 25% of our universe.
