    <p>For over a decade, floating cranes have been lowering unusual cargo to depths of around 3,000 meters in the Mediterranean. These objects resemble something from a different realm: large, shiny spheres filled with electronic devices. In reality, they are detectors for a project called <a href="https://www.km3net.org/">KM3Net</a>, which aims to explore one of the most enigmatic fundamental particles.</p>
    <p>The facility has been in operation for only a few years. In 2023, <a href="https://www.cppm.in2p3.fr/web/en/pratical_info/directory/Y295bGVAY3BwbS5pbjJwMy5mcg==.html">Paschal Coyle</a> was astonished to discover a significant signal in the preliminary data. While it turned out to be a neutrino, it was unlike anything previously observed. "My program crashed when I first encountered this event," recalls Coyle, a physicist from the Centre for Particle Physics in Marseille, France.</p>

    <p>KM3Net detected neutrinos with roughly 35 times the energy of any previously recorded instances. These neutrinos were thousands of times more energetic than those produced by our best particle accelerators. Neutrinos are notoriously difficult to study as they interact very weakly with matter, making their detection elusive. This challenge was a key factor in placing the detectors on the ocean floor, a decision that seemed almost improbable.</p>
    <p>Now, the scientific community is racing to understand what could have generated this phenomenon in space. Astronomers are exploring two primary theories, both of which delve into some of the universe's most profound mysteries. Unraveling the origin of this particle will enhance our understanding of neutrinos and...</p>
